VLM lamellar mats are formed from basalt wool bars with a density of 25 to 65 kg/m3, fixed adhesive method on special substrates. As substrates are used:

reinforced aluminum foil;
Foiled fiberglass fabric Outside.

In the first case, the operation of vertically layered mats is limited by the thermal insulation of internal (protected from negative environmental factors) communication lines, in the second case there are no restrictions, which significantly expands the operational capabilities.

The main field of application of VLM lamellar mats is the thermal insulation of pipelines and air ducts, the alternative is the thermal insulation of casings of various equipment and tanks. In addition, the mentioned mats are truly universal and retain their effectiveness on any structures and on any equipment.

They are fixed on insulated surfaces in two ways:

tightening with bandage belts (this method is used for thermal insulation of pipelines and air ducts);
gluing (used for thermal insulation of casings and tanks, as well as other large objects).

Technical characteristics of lamellar (vertically layered) VLM mats

The width of VLM lamellar mats is 1 m, the length varies from 2.5 to 15 m. Their thickness can also be different: its lower limit is 40 mm, the upper one is 200 mm. The dimensions of the mats do not change either when heated/cooled or moistened/drying (their coefficients of thermal expansion and shrinkage are zero).

At the minimum density of VLM vertically layered mats (it is 25 kg/m3), their compressive strength is 5 kN/m2, at the maximum density (65 kg/m3) it reaches 10 kN/m2. But water absorption does not depend on density and never exceeds 1.5%. Wet mats do not affect their service life, but increase thermal conductivity.

The operating temperature range of VLM lamellar mats is quite wide: their operation is possible at temperatures from -180 to +350 C. Short-term exposure is more than high temperatures also allowed. The fire-technical classification classifies VLM mats into the following groups.

in terms of combustibility - G1 (low combustible);
flammability - B1 (flammable);
according to smoke-generating ability - D1 (practically not forming smoke);
according to the toxicity of combustion products - T1 (minimal danger).

Distinctive features lamellar (vertically layered) VLM mats

Durable and extremely easy to install, VLM lamellar mats are one of the special thermal insulation materials widely used both in industry and in the housing and communal services sector. The reason for this is their outstanding performance features, which include:

oil resistance, various types fuels, solvents, alkalis and even acids;
significant deformation ability (the compressibility of the lamellas reaches 10%);
high insulating potential.

Use of vertically layered mats for thermal insulation ventilation ducts(air ducts) allows not only to prevent unwanted cooling of the air transmitted through them, but also to neutralize the noise created by its intense current. Mats made on the basis of Outside fabric also have waterproofing properties, protecting air ducts laid in open space from corrosion.

Deliveries of VLM lamellar mats to consumers are made in the form of rolls of various footage, packed in polyethylene film. After opening the package, the mats are completely ready for installation.

It is allowed, upon agreement between the manufacturer and the consumer, to use other covering and adhesive materials. Maximum deviations in the dimensions of the mats should not exceed: along the length + 3%; -1% in width ± 10 mm in thickness + 3; 0 mm (for 40, 50) + 5; 0 mm (for 60, 70, 80, 90, 100). The variation in the thickness of the mat should not exceed 5 mm. 4

5 2.3; 2.4. (Changed edition, Rev. 2) The gap between the mineral wool strips constituting the mat s should not exceed 2 mm According to the physical and mechanical parameters, the mats must meet the requirements specified in Table. 2. Table 2 Name of the indicator Value for mats of the brand Density, kg / m 3 From 50 to 75 St. 75 to 125 Compressibility under a specific load of 2000 Pa (0.02 kgf / cm 2,%, no more than 3 2 Thermal conductivity, W / (m K), not more, at temperature: a) (298±5)K 0.048 0.046 b) (398±5)K 0.083 0 2.7. (Revised edition, Rev. 2). 5

6 3. ACCEPTANCE RULES 3.1. Acceptance of mats should be carried out in accordance with the requirements of GOST and this standard. The volume of a lot of mats is set in the amount of not more than a shift working. the mat included in the sample is determined for each game. Thermal conductivity is determined once a quarter and with each change in raw materials and production technology on three mats that have passed acceptance tests according to the indicator for which the batch was not accepted. When a batch of mats is rejected, based on the results of determining the thermal conductivity, a re-check is carried out. Upon receipt of unsatisfactory results of the repeated check, the supply of mats to the consumer should be stopped. After eliminating the causes of the release of low-quality mats, each batch is subjected to control. Upon receipt of satisfactory results for three consecutive batches, it is allowed to carry out periodic control according to Sec. 3. (Revised edition, Rev. 2). 4. TEST METHODS 4.1, 4.2. (Excluded, Rev. 1) The length, width and thickness of the mats are measured according to GOST on a mat laid with mineral wool strips up. 6

7 The thickness of the mat is measured at a specific load of 500 Pa (0.005 kgf / cm 2). The size of the gaps between the mineral wool strips is determined after every fifth strip of the measured product. (Changed edition, Rev. 1, 2) The difference in thickness is determined by the results of measuring the thickness of the mats according to n The difference in thickness is calculated as the difference between the largest and smallest values of the mat thickness The width of the longitudinal edge is measured with an error of up to 1 mm in six places and is calculated as the arithmetic mean of the measurements made Density determined without taking into account the cover material according to GOST (Changed edition, Rev. 1, 2) The compressibility of the mat is determined according to GOST From each mat that fell into the sample according to clause 3.1, two samples are cut out together with the cover material The thermal conductivity of the mat is determined according to GOST From each mat , selected according to clause 3.3, are cut out in one sample without cover material The moisture content of the mat is determined according to GOST selection according to n The strength of bonding of mineral wool strips to the cover material is determined by examining the mat after it has been rolled up twice and then unrolled on a flat surface. The mat is deemed to have passed the test if, after the second unfolding and turning the mat with the strips down, not a single strip is completely separated from the covering material. 7

8 (Revised edition, Rev. 2). 5. PACKAGING, MARKING, TRANSPORTATION AND STORAGE 5.1. Packing, marking, transportation and storage of mats is carried out in accordance with the requirements of GOST and this standard. (Revised edition, Rev. 2). 5.la. Mats must be rolled up. Roll weight - no more than 50 kg, roll diameter - no more than 400 mm. Mats up to 1500 mm long can be delivered unfolded in stacks. The foot is wrapped with a strip of paper, the end of the paper web is sealed. Foot mass - no more than 50 kg, foot height - no more than 500 mm. Transport packages are formed in accordance with the rules for the carriage of goods, the sizes of packages and the means of packaging are in accordance with GOST (Introduced additionally, Amend. 2) Transportation of mats in open vehicles at a distance of up to 200 km is allowed with the obligatory covering of them with a tarpaulin or other moisture-proof material. Transportation of mats by rail is carried out by carload shipments. Transport marking is carried out with the application of the manipulation sign “Afraid of dampness” in accordance with GOST The height of the stack during storage should not be more than 2 m. 8

9 (Revised edition, Rev. 1, 2). 6. MANUFACTURER WARRANTY 6.1. The manufacturer guarantees the compliance of the mats with the requirements of this standard subject to the conditions of transportation and storage established by this standard. Guaranteed shelf life of mats - 6 months from the date of their manufacture. Sec. 6. (Introduced additionally, Rev. 1). INFORMATION DATA 1.
