What is conductive linoleum: characteristics and installation features. Which antistatic linoleum to choose Copper tape for laying antistatic linoleum

Arrangement problem high-quality coating on the floor these days is acute. It must be suitable for the working conditions, surrounding people environment, ensure reliability and safety. In a room where a large number of electrical appliances are used, static electricity and other troubles appear. To solve this problem, antistatic linoleum was created, eliminating excess electricity and providing conditions for human life and work.

Antistatic coating on the floor in the room with electrical equipment

Antistatic linoleum: necessity, scope

There is a PVC material that reduces static electricity. It is called antistatic linoleum. This type coatings have found application in rooms where a large number of electrically sensitive equipment is installed:

• in laboratories;
• in different computer centers;
• in ultrasound, MRI and other rooms.

The coating is used to protect against the effects of computers, televisions, microwave ovens. This kind of linoleum is becoming popular for use in residential areas, where there are a lot of household appliances, devices that are a source of static voltage.

Often there is contact between a person and metal devices, a slight electrical discharge occurs, which the person feels on himself. Besides this category negatively affects the functioning of household appliances, devices, equipment; Static electricity contributes to the accumulation of dust. Therefore, you should use commercial linoleum that copes with these problems.

Construction of building materials

Antistatic linoleum consists of polyvinyl chloride, which is considered an insulating material. The polymer material has the ability to accumulate electricity. To reduce its level, use a coating with low resistance and grounding elements.

Metal tapes are often used for PVC coating. They (usually copper) are highly conductive and help dissipate static current. To improve grounding, linoleum with inserted copper strips is laid on special glue with high conductivity.

Types of antistatic linoleum

This type of coating is unique due to its ability to be used in places where the use of other coatings is impossible, especially in rooms with high electrical resistance. Based on current conductivity, antistatic linoleum is divided into types with their own characteristics:

• With a resistance greater than 109 Ohms: a popular type, used in schools and computer classes.
• Linoleum, the resistance of which is in the range of 107–108 Ohms (current dissipative). Carbon thread, glue, and other additives provide the required scattering properties. The material is widely used in server rooms, fluorography rooms, chemotherapy rooms, and other medical rooms.
• With a resistance in the range of 104–106 Ohms (conductive linoleum), the composition contains graphite, which removes electrical charge from the floor. The building material is not widespread and is used in large-scale premises of plants, factories, industrial enterprises equipped with new technical inventions. Its high conductivity eliminates the possibility of electric shock upon contact with the metal surface of structures, devices, and furniture.

Such linoleum must comply with GOST: 11529, 11529-68, etc. This information is familiarized with when purchasing the material - specifications is on the label.

Technical characteristics, pros and cons of linoleum

Conductive linoleum and others have a number of positive characteristics:

• PVC coating is good insulator. However, for antistatic purposes, plasticizers are added to the composition, reducing the resistance to 109 Ohms. When walking on such a surface, a charge of no more than 2 kW occurs, which allows it to be dissipated throughout the surface.
• The material is laid in any residential, public, industrial premises, since there is no relationship between electrical resistance and humidity.
• It must meet high levels of strength and wear resistance, since non-uniformity of the coating thickness leads to incorrect charge distribution. This also applies to the evenness of the subfloor.
• The material has good level thermal insulation, elasticity, sound insulation.
• Heat-resistant, difficult to ignite.
• Has a high light fastness rate.
• The coating is recommended for use in medical institutions due to its hygiene characteristics (easy to clean, washable).
• Resists temperature changes.
• The product has a wide color palette.
• It is used under a “warm floor” system.
• Moisture resistance prevents delamination, rotting, and destruction of the material.
• It has an affordable price - cheaper than other types of coatings.
• In terms of durability, the material is not inferior to tiles.

Despite the large list positive points and high technical characteristics, antistatic linoleum has a couple of disadvantages: it is inferior in beauty to parquet, laminate, wood, and is sensitive to mechanical stress.

Popular brands and cover prices

Purchasing such a coating is not difficult - linoleum is available in stores in wide range. The main thing is to choose quality material.

Attention! Before purchasing material, you must require a certificate of quality and compliance with GOST.

From total number There are three brands:

• Tarkett;
• Forbo (Smaragd collection);
• Armstrong.

Despite the fact that these linoleum models cost less than other coatings, the prices for the products cannot be called low. By the way, buying this building material, should be purchased Additional materials for its installation, for example, copper tapes, conductive glue, primer. The cost of the coverage may include the installation of grounding, as well as the salary of the craftsmen who will perform this work.

Linoleum installation technology

Laying antistatic linoleum consists of two stages: preparation of the base and installation insulating material. The work requires appropriate tools and materials.

Tools required for work

To install antistatic linoleum, you need a set of materials and tools:

• primer, putty;
• brush;
• rags;
• roulette;
• drill;
• knife, scissors;
• Master OK;
• screws, nails.

You will also need copper strips for grounding, insulation sheets (linoleum), and special glue.

Preparatory work before laying the material

Before installing the covering, the base is carefully prepared - it should be leveled and screeded.

During operation, a certain microclimate is maintained in the room: humidity - up to 60%, air temperature - above 18 degrees. Before starting work, commercial antistatic linoleum is left in the room, having previously made markings and cut with scissors (knife) into the required number of sheets.

The base is carefully prepared - it must be clean, dry, and even. All irregularities and defects are puttied and primed, and a layer of putty is applied with a thickness of more than 2 mm.

Installation procedure

The laying technology has a number of subtleties and features characteristic of this type of material: temperature, humidity conditions, adaptation to conditions.

Important! When buying linoleum, pay attention to its appearance: there should be no kinks or folds.

An important condition when laying conductive linoleum is to ensure contact with grounding, correct selection glue (so that it maintains conductivity). The use of neoprene-based contact adhesive is prohibited - the floor will change tone without providing the required effect. The issue with grounding is solved using copper tape and glue.

The sequence of actions is as follows:

• First of all, a mesh of copper tapes is mounted on a base coated with a special primer. Part of it is placed along each joining seam, retreating 200 mm from the edge. The other part is placed across, connecting to the laid one. Then the resulting mesh is connected to the grounding system.

Attention! If there is no grounding, then it is pre-installed.

• Then they prepare a special conductive glue for linoleum. It is purchased at the same time as the material so that the adhesive composition is optimally suited. Before using the glue, read the instructions: different compositions have their own characteristics.
• Strips of material are immediately placed on freshly prepared glue, since if the of this rule the quality of the flooring deteriorates.
• Glue is applied to copper strips and allowed to dry. The linoleum is completely glued and applied according to the instructions.
• To achieve full contact, air bubbles are removed using a special roller in two directions. If necessary, make a cut in the coating, but so as not to damage the copper strips. The process is continued until the coating adheres firmly. A plinth is installed around the perimeter of the room.

Antistatic linoleum is a reliable, popular material for flooring in production, commercial and residential premises. He has a number positive qualities. The installation of the coating can be entrusted to professionals, or you can do it yourself. In the latter case, you need to know the sequence of work stages and proper organization grounding.

It is impossible to imagine a modern clinic without large quantity high-precision electronic diagnostic, treatment and preventive equipment, without computers and other equipment. Stable operation of any electronic component directly depends on the level of electrical conductivity of the floor coverings in the room. When we're talking about about the health and safety of patients - compromise is impossible. That is why Armstrong's Conductive Series homogeneous conductive coatings with low electrical resistance (less than 10 in 6 ohms) are specially designed for the accuracy and stability of electronic equipment in any type of healthcare facility.

What is the difference between conductive linoleum and antistatic linoleum?

Clients often contact our company with a desire to buy antistatic linoleum. But when you start to understand, it turns out that they do not need an antistatic agent, but conductive or current-dissipating linoleum. What's the difference? Firstly, the difference in resistance - conductive linoleum has a resistance of 1x10 4 -1x10 6 Ohm inclusive, current dissipating linoleum has a resistance of 1x10 6 -1x10 8 Ohm, antistatic linoleum - 1x10 9 ohms. Secondly, conductive linoleum and current-dissipative linoleum discharge the charge along the thickness into the ground, and in antistatic linoleum the static charge simply spreads over the surface. Antistatic linoleum is used mainly in large offices and call centers; it cannot be used in medicine, despite the fact that there are still designers who write antistatic linoleum in their projects (still according to the Soviet standard) instead of conductive.

An electrostatic charge constantly generated on the floor surface can cause irreparable damage to equipment and cause a lot of inconvenience to staff and patients. Decreased electrical resistance flooring allows you to instantly remove static charge, ensuring safety and comfort in the room. Hi-tech DLW Armstrong guarantees the material lifelong conductive properties - due to the introduction of graphite inserts into the structure of the material.

How to save on conductive linoleum?

In 2012, the Armstrong company released a new product in conductive linoleum, conductive linoleum Royal Conductive LG2, which has a graphite layer as a substrate and can be glued to regular glue for pvc linoleum. If other conductive linoleums are glued with conductive glue and require the mandatory use of copper tape, then for Armstrong Royal Conductive linoleum copper tape is needed only as a contour around the perimeter and expensive conductive glue is not needed at all; ordinary glue for PVC linoleum, which is half the price, is sufficient.

Therefore, by overpaying a little for the Armstrong Royal Conductive conductive linoleum itself, you save on the cost of glue (regular glue is half the price of conductive glue), on copper tape (much less of it is needed) and on the cost of work (no need to glue copper tape), in the end you save from 10 to 20% of the cost.

Conductive linoleum in tiles

Conductive linoleum is also available in tiles; this is more convenient for small rooms - there are fewer scraps and there is no need to buy multiple rolls (45.8 m2). But the installation work is more complicated and therefore more expensive, and also if indoors high humidity or when they wash and spill a lot of water, then soon the conductive pvc tiles it will peel off and its corners will bend, since it is glued with water-dispersed adhesives, which are destroyed by water.

Technical characteristics of conductive linoleum
Armstrong Royal Conductive

• homogeneous coating 180 cm wide, 2.2 mm thick.
• per roll 45.8 m2 (tiles 60.8x60.8 cm)
• vertical resistance: less than 1x10 6 ohms
• antistatic properties less than 0.1 kV
• usage class 34/43
• slip coefficient R9
• abrasion coefficient P

Armstrong Royal Conductive conductive linoleum is recommended for use in operating rooms, intensive care boxes and resuscitation rooms, “clean” rooms, as part of the raised floor system, server rooms, MRI rooms, radiography and functional diagnostics.

Antistatic linoleum – group floor PVC materials that prevent the formation of static currents and residual voltage on their surface when a person walks with simultaneous contact with various electrical appliances. Usage of this type floor coverings are regulated by GOST 11529-86 and GOST 6433.2-71. Linoleum with antistatic properties is recommended for installation in laboratories with big amount measuring instruments, offices, computer school classes and other rooms where there is a risk of residual stress forming on the surfaces of furniture and equipment.

Antistatic linoleum can compete with traditional and rubberized coatings.

PVC coating with antistatic properties - what is it?

If we consider the technical characteristics of linoleum as a whole, then each type has a different antistatic effect. Any PVC coating is called insulating. However, materials are capable of accumulating some charge on their surface, and therefore they are not traditionally mounted for additional protection from free currents.
To ensure a sufficient level of safety, the coating must contain:

• carbon additives – they are present both throughout the material as impurities and in the form of an interlayer. Additives can dissipate the charge. The current, having reached the carbon layer, stops there, is redistributed and, having reached grounding, leaves the room circuit;
• graphite inserts – such commercial linoleum is capable of instantly removing free charge from the room, and therefore its installation is appropriate in rooms with a large number of electrical equipment.

Classification of flooring material:

• traditional antistatic linoleum– its resistance must be at least 109 Ohms. A mandatory condition for using such a coating is that a voltage higher than 2 kilowatts should not form on its surface. Its installation is appropriate in computer classes and various service areas;
• current dissipative commercial material with a resistance of 106-108 Ohms - its antistatic characteristics are provided by carbon additives. This one is commercial flooring material relevant for x-ray rooms, offices;
• conductive with a resistance of up to 106 Ohms - graphite inserts are responsible for distributing the charge and removing it from the room. The material is recommended for use in industrial buildings.

The difference between the materials lies not only in structure and resistance, but also in installation. Installation of the first type is carried out traditionally glue method. To fully use the second one, you need copper tape or mesh and special conductive glue.

Tarkett – modern flooring

Among all the manufacturers of floor coverings that protect against free charge, the international brand Tarkett and its commercial linoleum stand out. The technical characteristics of the company's product comply with TU No. 5771-021-54031669-2009.
Antistatic linoleum tarkett and its main types:

• traditional products with increased protection against voltage and current - ACCZENT MINERAL AS line;
• current-dissipating commercial linoleum GRANIT SD line;
• conductive material - TORO SC line.

The traditional product of this brand is sold in rolls of 15 m or 20 m. The first is enough to cover 60 sq. m., the second – 80 sq. m. The material has additional protective covering PUR, it is slip-resistant (R9), its wear resistance meets the requirements of group “T”. It is moisture resistant. In addition, other technical characteristics of the coating of this brand differ depending on the line. When sold, antistatic linoleum must be accompanied by a certificate of conformity, which confirms its originality.

Installing antistatic flooring

Laying antistatic linoleum is somewhat different from installing a similar material with conventional properties. From the correctness of the installation work in the future, the characteristics and protective properties of the coating completely depend, and therefore the installation of antistatic linoleum should be carried out by professionals.

Stages of work:

• surface preparation. Antistatic linoleum is demanding in terms of surface evenness, like any other floor covering. IN in this case The skew of the horizontal coating should not exceed 2 mm per 1 sq. m. Any surface (if necessary) is leveled, dried, degreased, and treated with an antibacterial primer. Installation of the material involves the use of special primers that increase the surface resistance to electric current;
• cutting the material - antistatic linoleum must remain in the room for at least a day before installation so that its structure adapts to the temperature and humidity conditions of the room. Next it is spread on the floor in the room. It is cut according to the contour and geometry of the room. Then it is rolled back into a roll;

• conductive glue and strip are a mandatory attribute (according to GOST 6433.2). The strip can be self-adhesive, but in most cases its installation is carried out with glue. The main function of conductive auxiliary elements is to create a diversion potential. The tape is laid in increments of 20 cm, the distance from it to the wall should also be 20 cm. The end of the tape is connected to the ground;
• direct installation. As soon as the glue for the conductive strip has gained the required strength, the floor covering is installed. The glue is applied to the back surface of the material using a notched trowel. The decorating layer is laid from the middle of the room. The glue is applied as the roll unwinds. After one roll has been unrolled, it is carefully aligned.

Depending on the initial characteristics materials used, the room where commercial flooring material with antistatic properties was laid can be used within 24 hours.

Linoleum has been and remains one of the popular finishing materials for the floor. There are several reasons for its popularity: relatively low price, speed of installation and wide specification of types of linoleum.

You are probably familiar that linoleum produced by industry is strictly classified according to purpose and application. And the first division of linoleum into household, commercial and commercial flooring. Household linoleum Designed for apartments, houses and other premises with low traffic. This linoleum has a lower abrasion rate. According to its characteristics, commercial linoleum is produced specifically for premises with high traffic (gyms, offices, shops) or premises special purpose.

In this article we are interested in commercial linoleum for special premises. It is logical that such linoleum is called: commercial linoleum for special purposes.

Types of special purpose linoleum

Speaking about special-purpose linoleums, we are faced with two concepts that household level contradict each other. This is linoleum and electricity. However, it is the interaction of linoleum with electricity that distinguishes special commercial linoleums.

There are three types of special commercial linoleums: conductive linoleum, current dissipative linoleum, antistatic linoleum. The types of special linoleum differ in their electrical resistance.

• Conductive linoleum (10 6 Ohm). Ten to the sixth power Om;
• Current dissipative linoleum (10 6 -10 8 Ohm);
• Linoleum with antistatic properties (10 9 Ohm). Ten to the ninth power Om.

Let us analyze the features of special linoleum using the example of the characteristics and purpose of conductive linoleum.

Conductive linoleum and its characteristics

The task of conductive linoleum is to quickly drain electric charge from the linoleum surface to the grounding system. For these purposes back side conductive linoleum is covered with a special conductive layer, often graphite.

Conductive linoleum is used in special purpose premises:

• Server rooms;
• Automatic telephone exchanges;
• Computer data centers;
• Scientific laboratories;
• High precision manufacturing;
• Medical rooms with X-rays, tomography, treatment rooms, operating rooms.

Features of laying conductive linoleum

In conclusion, I will list the features of laying special conductive linoleum:

• Conductive linoleum is laid on a very well leveled base;
• To lay conductive linoleum, you do not need special conductive glue. This fundamentally distinguishes it from current-dissipating linoleum. By the way, to lay current-dissipating linoleum you also need a copper mesh under the linoleum;
• To remove the electrical charge, a flexible grounding bus is placed under the current-carrying linoleum, which is connected to the room’s grounding system.

Conclusions and prices for linoleum

Antistatic linoleum, although classified as special, is widely used in household and office premises. The cheapest linoleum in this line.

Current dissipative linoleum used in rooms with a small amount of electrical equipment (server rooms). Middle price segment.
