Which antistatic linoleum to choose. Antistatic linoleum: technical characteristics and reviews How to lay antistatic tape under linoleum

Currently, antistatic coating is an irreplaceable thing in any house or apartment. IN modern home There are many different devices that are sources of static electricity. Highest value have computers, televisions, microwave ovens and other equipment. To protect against the harmful effects of electrostatic electricity, antistatic linoleum is successfully used. Under normal conditions, contact with metal appliances in the home can be dangerous to humans. Very often, cases of mild electrical discharges occur, and residents feel this on their bodies.

Of great importance is the fact that high levels Static electricity can negatively affect the operation of equipment. Malfunctions and breakdowns often occur. In addition, static electricity contributes to the accumulation of dust, which is especially noticeable on the floor. Antistatic linoleum allows you to cope with all of the above problems. Let us consider in more detail how antistatic linoleum is laid, the main stages of work, necessary tools and materials.

Advantages of antistatic linoleum

The colors of linoleum can be quite varied.

Pretty simple. What are the advantages of this material over others? Antistatic linoleum, which everyone loves so much, is flooring, which prevents the formation and accumulation of static electricity. Simple materials upon contact and friction with objects they are easily electrified. This valuable linoleum is made from polyvinyl chloride. The advantage of linoleum is that it is widely used both in residential buildings and in production. TO positive aspects it can be used in rooms with high-precision equipment.
In this case, it is practically irreplaceable. It is also important that antistatic linoleum is reliable and safe material, which can last for many years. It is resistant to mechanical stress, that is, there are no problems when cleaning and washing it. Laying antistatic linoleum is also good because it creates excellent sound insulation.

The advantage of PVC flooring is its resistance to high temperatures.

Thanks to this property, it is less dangerous in terms of fire. In terms of durability, it is not inferior to tiles and marble.
Antistatic linoleum is widely used in rooms with high voltage equipment.

Modern technologies for its production make it possible to choose linoleum of any color and design for your home or apartment. The technical characteristics of this flooring include good elasticity and wear resistance. Linoleum can withstand the effects of acids, alkalis, and oils. It does not change its shape under mechanical influence (from pressure from the legs of chairs or a table). Very big advantage it is possible to lay it on the floor with electrically heated.

Types of antistatic linoleum

Linoleum can be divided into several types: antistatic, current dissipative and conductive. They are all somewhat different from each other. To lay linoleum, you will need to select a material. So, antistatic linoleum can be called a PVC-based material that has a high resistance to electric current. When a person walks on it, a voltage of no more than 2 kV is generated. This material is great for computer classes.

Due to its structure, conductive linoleum has a resistance of 1000 MegaOhms.

As for the current-dissipating coating, the resistance it creates is 100-1000 MegaOhms. It differs from the previous version in that it contains carbon particles. With their help, the resulting electric current quickly disperses throughout the material. This reduces the danger of the material to humans. This coating is often used in X-ray rooms. The third type is conductive linoleum, which has a resistance of 10 kiloOhm-10 MegaOhm. It includes graphite additives that promote better current dissipation from the coating. This type of linoleum is used in laboratories and other premises with a large number complex equipment.

Preparatory work

The technology for laying this type of flooring includes 2 main stages: preparing the base and directly laying the insulating material. To lay linoleum, you need to carefully select materials and prepare the coating.

The floor must be leveled as best as possible before laying linoleum. Of course, it is best to make a screed.

Firstly, for normal installation, a certain microclimate must be maintained in the room. The temperature should not be lower than 18 degrees, the optimal relative humidity is 30-60%. Before laying, the sheets are left in the room for some time. Laying the coating also includes marking the material. To do this, use a tape measure to measure the area of the room and determine required quantity sheets. Linoleum can be cut with a knife or scissors.

The subfloor must be dry, clean and level. If there are defects and unevenness, it is recommended to use a primer or putty. To give the base a flat surface suitable for chairs on wheels, putty is applied with a layer of 1.5-2 mm. If installation is planned on water-sensitive materials, the putty layer should be at least 2 mm thick.

Nowadays, the problem associated with the use of large quantity various electrical appliances, as a result of which static electricity accumulates in the room. As a result of this, malfunctions occur in the operation of computers, faxes and telephone exchanges, and, in addition, even touching an ordinary door handle often produces a fairly noticeable electrical discharge. Decide this problem possible by using a special coating - antistatic linoleum.

This type of linoleum is produced specifically to combat excess electrification of floor coverings, both in residential and non-residential premises. The antistatic coating reduces the accumulation of dust, fire and explosion hazards significantly prevent the negative effects of static on highly sensitive devices.

Antistatic linoleum is a PVC floor covering characterized by antistatic properties, that is, allowing to minimize the formation of static charges upon contact with another material, friction of one material against another, etc.

The main advantages of antistatic linoleum is the ability to use it in rooms with high-precision equipment, in which the use of other types of linoleum is unacceptable. In addition, this flooring is highly reliable, resistant to external influences, hygiene and ease of care. Also, antistatic linoleum has high sound insulation and resistance to high temperatures. This coating has wide variety color range, which makes it possible to choose suitable option any room design. The service life of antistatic linoleum is comparable to marble or tiles.

There are three types of antistatic PVC, depending on conductivity:

Antistatic linoleum has an electrical resistance of at least 109 Ohms. Linoleum can be considered antistatic provided that walking on it causes no more than 2 kilovolts of voltage. These coatings are also sometimes called insulating coatings. It will be noted that almost any commercial coating has antistatic properties and all the above characteristics, therefore, if the floor special requirements is not presented, then you can safely use it. This type of linoleum is often used in computer classes, service rooms and call centers.

Current-dissipating linoleum has a resistance of 106-108 Ohms. To give such linoleum current-dissipating properties, special additives (carbon particles or carbon filaments) are included in its composition. In this case, the electrical charge generated when walking on the surface quickly dissipates throughout the floor, and static charges become harmless. Current dissipative coatings are used in X-ray rooms, server rooms, etc.

Conductive linoleum has a resistance of 104-106 Ohms. These coatings contain graphite additives, which ensure excellent conductivity and instant removal of electrical charge from the floor. This linoleum is used in rooms with expensive and highly sensitive industrial equipment.

There is often a little confusion, and antistatic linoleum refers to all three types of coatings. However, this is incorrect, since there is big difference, both in characteristics and production features and installation methods. In normal office space As a rule, the use of the first type of coating is sufficient, but rooms saturated with equipment and electronics (automatic telephone exchange rooms, operating rooms, testing laboratories, etc.) require the use of the third type of linoleum. One way or another, you should not choose the coating yourself; it is best to consult with experienced specialists.

As you can see, the scope of application of antistatic linoleum is extensive. To be sure of the safety of work at industrial facilities, it is important that the resistance is the same at all points of the floor covering. In addition, the resistance value of the floor covering throughout its entire service life must remain unchanged, since human lives depend on the quality of the floor covering in industrial facilities.

Laying antistatic linoleum is carried out using long-established technology. The old coating is removed, a layer of glue is applied, on which the linoleum is laid. To install the current dissipative coating, you will also need to use a mesh of copper tape and conductive adhesive.

Thus, antistatic linoleum is an indispensable material for finishing works in household and production premises. Its price is slightly higher, however, in terms of functionality it is far superior common species linoleum.

The steadily increasing number of household and industrial equipment has led to the emergence of such commercial coating as antistatic linoleum, which has very specific characteristics.

Life modern man is unthinkable without various electrical appliances, but their use leads to the accumulation of static electricity in the room, and this serves main reason interruptions in the operation of computers, printers, and any other equipment. Sometimes a fairly noticeable electric charge can be obtained simply by touching metal objects.

Antistatic linoleum: characteristics and properties

The main structural component is polyvinyl chloride with the addition of antistatic particles. They have truly unique abilities - they eliminate static electricity. As a result, dust does not accumulate on the linoleum, and particularly sensitive equipment is protected from static.

Types of paintings

Linoleum with an antistatic effect is divided into three groups:

Antistatic coatings generating a voltage of no more than 2 kW. Minimum resistance 109 ohms.
Current dissipative, having a resistance of 106–108 Ohms. In order for current-dissipating linoleum to fulfill its main function, the composition includes carbon particles or threads, thanks to which electric charges arising during movement are instantly dissipated over the entire surface, becoming completely harmless.
Conductive, with special graphite additives that ensure impeccable conductivity, resulting in lightning-fast removal of charges from the surface. Such linoleums have a resistance of at least 104 Ohms.

The scope of application of antistatic PVC coatings is private homes, electrical assembly shops, power plants, computer classes, laboratories, medical institutions, in particular, operating rooms, ultrasound/MRI rooms, X-ray rooms, etc., where it is necessary to minimize the accumulation of electrical charges .

Specifications

It is permissible to lay antistatic sheets on heated floors with a maximum heating temperature of up to +27° C.

Advantages and Disadvantages

The undoubted advantage is versatility. Antistatic linoleum is successfully used both in houses/apartments and in production workshops.

High safety and hygiene indicators are due to the absence of heavy chemicals, which allows its installation in children's institutions and bedrooms. And excellent moisture resistance significantly expands the range of use.

Sufficient thickness of the product provides good heat and sound insulation parameters, resistance to various mechanical loads. Durability is comparable to the service life of tiles and marble, as a result of which it can be safely laid even in rooms with excessive load intensity.

The inability to accumulate dust greatly simplifies the maintenance process, and high resistance to exposure chemical compounds and phenomenal color-fast parameters will help maintain a presentable appearance for a long time.

Antistatic PVC linoleum is presented in a huge range of colors and textures. In addition to traditional rolls, it is produced in the form of tiles with a laminate pattern, parquet board and other finishing materials.

The main disadvantages are: the composition is not environmentally friendly, the possibility of installation only on a prepared (leveled) base and high cost.

When choosing antistatic linoleum, you need to take into account its class. Greater value corresponds to thicker protective layer, and, therefore, such coatings will last longer.

Do not forget about the color characteristics - in accordance with them, you can choose the material to suit any style.

It is advisable to pay attention to abrasion and deformation rates declared by the manufacturers. In addition, it must fulfill its main role, which is to eliminate electrical charges. Therefore, you need to choose products with the highest degree of resistance.

For ordinary offices, it is enough to purchase commercial antistatic linoleum, for rooms with a large number of electrical devices and equipment ideal option– current dissipative or conductive.

Antistatic coatings are laid using classic scheme. It is necessary to dismantle the old floor finishing, carefully level the floor and treat it with a conductive primer solution to ensure good adhesion to the glue and the underside of the linoleum.

A leveled plane is needed not only to eliminate unevenness on the laid linoleum and eliminate the possibility of damage to its lower layer, but also to distribute stress evenly.

The base is coated with a thin layer adhesive composition, and direct laying of the canvases is carried out end-to-end. It is strictly not recommended to use adhesive made on the basis of neoprene, as it does not interact well with the coating, which will lead to loss of color characteristics.

Current-dissipating linoleum sheets involve the use of a special copper mesh installed to provide grounding and conductive adhesive.

The final stage is the elimination of air bubbles using a rubber roller, as well as opening the seams and then sealing them by hot welding.

Antistatic linoleum is a unique floor covering designed to protect others from static electricity. And thanks to the impeccable technical parameters it is deservedly considered one of the most practical and durable.

Antistatic linoleum, video

High quality coating for the floor has great value to date. This is due to the growing number electrical appliances in premises of any type. Due to electricity, too much static energy can be generated, which will interfere with normal work and human life. To eliminate this problem, use antistatic linoleum.

Scope of application

This type of flooring is designed specifically to eliminate excess static electricity. Regular linoleum is made from a material that does not conduct electricity well. When a person walks on it, small electrical charges may arise that are not harmful to people. But for working with very precise equipment, such interference is unacceptable. Moreover, these small charges may cause an explosive or flammable substance to ignite.

Antistatic linoleum finds its application in rooms where high-precision electronics operate, which are sensitive to any influence of electricity.

It attracts less dust and dirt, which is very important in medical institutions that require constant cleanliness. Thanks to the polyvinyl chloride material that is part of this floor covering, this linoleum reduces static electricity. Laboratories, computer centers, server rooms, operating rooms, computer rooms, MRI rooms are the main places where this coating is placed.

Recently, it has begun to be used in residential premises where many electrical appliances are installed. Appliances such as computers, televisions and microwave ovens also provide harmful radiation. When a person comes into contact with a metal device, a weak but noticeable discharge may occur. It not only has a negative impact on human health, but also has a bad effect on the equipment itself and contributes to a faster accumulation of dust. That's why Antistatic linoleum is recommended for use in any premises with a large number of equipment.

Advantages

In addition to the obvious advantages when using this coating in the premises listed above, antistatic linoleum has other advantages. This material is reliable and safe. It lasts a long time and is practically not subject to mechanical stress, accordingly, it is easy to clean and wash. In addition, this coating insulates sound well.

Another undoubted advantage is the fact that antistatic linoleum is resistant to high temperatures. Therefore, it does not pose a fire hazard.

And its durability can rival tile and marble. Antistatic linoleum has a high light resistance and can easily withstand temperature changes.

Thanks to modern technologies, on at the moment This linoleum can be purchased in any color and design. Moreover, it can be laid on an electrically heated floor. This material elastic, wear-resistant. It can withstand acid, alkali or oil. The legs of chairs and tables do not leave dents or marks on it.

Varieties

There are 3 types of antistatic linoleum according to the level of static protection it provides:

antistatic linoleum, as a rule, are installed in rooms with a large number of computers, for example, language laboratories or computer science classrooms at schools, as well as offices. Its resistance value is more than 109 ohms. Objects with voltages higher than 2 kV are not allowed on it. Its installation is done using ordinary glue. This type of linoleum is also called insulating.
current dissipative linoleum They are often placed in rooms where ultrasound diagnostics are performed, as well as in server rooms. The parameter of its vertical resistance should not be higher than 10⁹ Ohm. If an electric charge arises in some place of this coating, it will quickly dissipate over its entire area and cease to be dangerous. This linoleum is able to dissipate current due to the presence of a special impurity, which is carbon filaments and carbon particles. To install such a coating, you will need a special glue capable of conducting current and copper tape.
vertical resistance of conductive linoleum does not exceed 10⁶ Ohm. Due to its fairly low resistance, this type of coating quickly removes any resulting charge from the surface. To obtain such characteristics, graphite substances are added to it, which outwardly resemble a black mesh. Before laying electrically conductive linoleum, it is necessary to lay grounding. Scientific laboratories, operating rooms, and automatic telephone exchanges are the main areas of application of this type of coating.

Laying order

The technology for laying antistatic linoleum has several differences compared to the installation of a conventional coating. It is important to comply correct order work, since the manifestation of the protective properties of linoleum depends on this. It is advisable that the installation of this coating be carried out by professional workers.

Before starting work, it is necessary to prepare the floor surface. It must be level, and the distortion cannot be more than 2 mm per 1 square meter. If necessary, any surface is leveled, dried and degreased, and then treated with a special antibacterial primer. A special primer is chosen that helps increase the coating’s resistance to electric current.

You can cut the material only after the linoleum has been in the target room for about a day. This is important so that the material adapts to temperature conditions and humidity in the room. After a day, the coating is spread and cut in accordance with the contour and geometry of the room. After this, it can be rolled up again.

When laying antistatic linoleum, conductive adhesive and strips with the same characteristics must be used. There are self-adhesive strips, but more often they are also laid on glue. These auxiliary elements play an important role, as they create the diversion potential. Special attention should be given to grounding. It must be consistent with electrical safety standards and regulations.

Copper strips should be laid at a distance of 20 cm from each other and from the walls. Laying in stripes should be parallel to the joints of the linoleum. It is important to connect all grounding elements to each other. In areas with particular electrostatic sensitivity, conductive tapes are connected to a separate grounding system.

Installation begins when the conductive adhesive has reached the required strength. It is applied with a notched trowel reverse side linoleum as the roll unwinds. It is imperative to carefully align the roll after unwinding it. To get full contact and get rid of air bubbles, use a special roller. If absolutely necessary, you can make a neat cut in the coating without damaging the copper strips.

Usually, after 24 hours of work, you can already use a room with an antistatic coating.

But exact time expectations depend on the technical characteristics of the selected type of linoleum.

Features of care

For antistatic coating it is extremely important regular care and cleaning. Excessive accumulation of dust and dirt significantly reduces its electrostatic properties. In no case should you use polishes, rubs and various mastics when cleaning, as they are good insulators. Because of them, the coating may lose its electrically conductive properties. Recommended use degreasing compounds and mastics, capable of conducting current.

Popular coatings

Manufacturers of antistatic linoleum offer various options coatings Each of them is intended for its own area of application.

For example, commercial homogeneous linoleum widely used in public spaces, where the coating should be as wear-resistant as possible. The thickness of this material is 2 mm. It is durable, resistant to various types of dents and has good antistatic properties. The presence of a wide range of colors allows it to be used in rooms with different interiors.

Can be used in areas with electronic equipment antistatic linoleum with a thickness of about 4 mm. Additional thickness is provided by a special protective layer. There are linoleum options with a slip-resistant coating. Special moisture-resistant coatings are also available for sale. In rooms where it is necessary to ensure increased safety, linoleum with polyurethane reinforcement is laid.

Scheme for laying conductive coatings in rolls (linoleum, carpet)

Scheme of laying conductive coatings in tiles (conductive PVC tiles)

BASE PREPARATION:

The base for laying antistatic and conductive coatings must meet the same requirements as for laying any floor coverings:

dry - base moisture content is not more than 2.0%, measured using the carbide method;

durable - must have surface strength, should not crumble when parallel scratches are applied, strength must correspond to the expected loads;

flat - according to GOST, on a 2m base the gap between the ruler (rule) and the base should not exceed 2 mm;

monolithic;

clean - dust-free, without traces of dirt, oils, etc.

SURFACE PREPARATION:

Before laying antistatic and conductive coatings it is necessary to prime the base with a conductive dispersion primer Eurocol FORBO 041 Europrimer EL. In this case, the removal potential is carried out by self-adhesivecopper tapeEurocol FORBO801 . The discharge potential is grounded into the grounding bus (by an electrician) and glued deep into the room 1.5 - 2 meters over an area of up to 30 m². Indoors larger area it is necessary to carry out several potentials (depending on the area) in such a way that there is a grounding for every 30 m². If 041 Europrimer EL is not used, it is necessary to lay a mesh of copper tape over the entire area of the room.

For roll coatings: copper tapeis glued to the base under each roll along its entire length approximately in the middle of the roll. Next, a discharge potential is made from copper tape across the glued strips. This potential is glued on the basis that the charge is removed from a distance of no more than 10 m. For example, if you step back from the wall 9.9 m and stick a strip, then the distance to the next strip of copper tape will be 19.9 m, etc. In rooms up to 40 m² there are two discharge potentials. All potential discharges (transversely glued copper tapes) must be grounded into the ground bus (by an electrician).

For materials made in the form of tiles, it is necessary to lay copper tape under each row of tiles. Discharge potentials are carried out in the same way as in the case of roll coatings.

After the conductive dispersion primer has dried(after approximately 30 minutes) or after completing a grid ofcopper tapeEurostrip EL , prepare and lay the floor covering using appropriate adhesives:

All these adhesives are characterized by exceptionally high initial and final adhesive strength. After opening the can, the glue should be thoroughly mixed and applied to the base using a notched trowel.

The glue should be applied with a special notched trowel to the entire surface of the base, carefully and evenly, in a circular motion, without leaving any accumulations of glue on the base. After applying a certain amount of glue, you need to smooth out the “roundings” of the glue with a spatula. You should try to apply the glue in straight lines, because... In places of curves, the formation of magnetization zones and malfunctions in the operation of the current-conducting system are possible.

Work is done with only one side of the spatula - the other side should always remain clean. Excess glue is collected with a spatula back into the jar and closed. have special form"shark tooth"

It is necessary to change the side of the rack every 50 m².

WORKING CONDITIONS:

the room temperature must be stable for at least 48 hours before installation;

indoor air temperature - not lower than 18 degrees C;

base temperature - not lower than 15 degrees C;

relative humidity should not exceed 75%.

rolls must be acclimatized in the given room for at least 24 hours before installation;

rolls must be acclimatized to vertical position;

labels on prepared rolls must be easy to read - to control the article, color, roll number and batch number;

If more than one roll of the same color is stacked in a given room, you must ensure that all rolls are from the same batch.

LAYING COATINGS:

natural linoleum is laid strictly in one direction, according to the arrows on inside or marks that must be placed before starting work;

vinyl and PVC coating laid using the reverse method. The first sheet of coating is laid in one direction, the next one should be laid in the opposite direction (rotated 180˚) due to the peculiarities of the production of many PVC coatings.

LAYING ORDER:

unwind the rolls directly in front of the wall on which it will take place

gluing, cutting to the required length;

in order to ensure precise markings seams, you must first place

sheets overlap by 1.5 - 2 cm;

BONDING COATINGS:

It is possible to glue several panels at a time, or one panel at a time.

on the base, mark the border of the roll - the border of applying glue;

if the room width is small, lay out all the canvases, trim along the walls;

wrap the roll to the middle of its length;

to prevent the glue from being applied layer to layer in the middle of the roll, at the border of the wrapped covering sheets, mark a line with a pencil or construction lace;

using an appropriate notched trowel (TKV), glue is applied to the base, strictly observing the previously marked glue application boundary;

glue is applied from the wrapped covering to the wall (from the covering);

glue 234 Eurosol EL can be applied by contact; for this it is necessary to apply glue to both the base and the back of the coating;

For high-quality “welding” of linoleum, it is necessary to use only a professional one, in particular, a professional one with step-by-step air temperature control, special knives, fixtures, etc. PVC coatings are welded with a cord made from PVC materials, under the influence of temperature they are welded at the molecular level.
If you cut the fused cord in one pass, when the cord is still hot, then as a result, after the cord cools, a groove will remain - the cord shrinks when cooled. Such minor negligence can lead to significant deterioration appearance laid covering, since dirt and dust will always collect in the grooves. Also, when heated, the coating becomes soft and when cutting the cord, damage to the coating itself may occur.

NOTE:

It is not recommended to apply protective mastics to conductive systems, because this may lead to an increase electrical resistance and degrade the performance of coatings.
