Rubber and rubber-fabric plates

Rubber and rubber-fabric  plates in accordance with GOST 7338-90
Plates according to the destination, structure and method of manufacture produced the following brands:
ТМКЩ – heat frost acid alkali resistant;
Working environment: indoor air, air of containers, vessels: nitrogen, inert gases at a pressure of from 0.05 to 0.4 MПa or fresh water, marine, industrial, sewage without organic solvents and lubricants: salt solution with a concentration up to saturation; acid , an alkali concentration of not more than 20% at a pressure of 0.05 to 10.0 MПa. Temperature range: -45 to +80 º C.
AMC – weathering and oil resistant;
Operating environment: air of atmosphere, space, containers, vessels: nitrogen, inert gases at a pressure of from 0.05 to 0.4 MПa or petroleum-based oils from 0.05 to 10.0 MПa. Temperature range: -30 to +80 º C.
MБС - oil and petrol resistance;
Working environment: indoor air, air of vessels: inert gas at a pressure of from 0.05 to 0.4 MПa or oil and petroleum-based fuels, gas at a pressure of from 0.05 to 10.0 MПa nitrogen. Temperature range: -30 to +80 º C.
classes
1 - plate thickness from 1.0 to 20.0 mm, intended for the manufacture of rubber products, which serve to seal assemblies, working under a pressure greater than 0.1 MПa of pressure in excess of 0.1 MПa;
2 - a plate thickness of from 1.0 to 60.0 mm, intended for the manufacture of rubber products, which serve to seal assemblies, working under a pressure to 0.1 MПa, to prevent friction between metal surfaces, as well as perception of single shock or as washers, decking;
types:
Ф - shaped plate, manufactured by vulcanization in vulcanizing presses;
 H - unmolded plate manufactured by vulcanization boilers, as well as continuous vulcanizers.
 types
 I - rubber plate;
 II - rubber plate with one or more fabric layers. degrees of hardness (Shore A LU)
M - mild (35-50);
C - medium (50-65);
T-enhanced (65-85).
Plates rubber, or as they are called in a professional environment - rubber plates, can act as an independent product and semi-finished product for the manufacture of other products.
Technical not shaped rubber plates manufactured: width from 500-1200mm and a thickness of 5-20mm.
Symbol plates must contain the word "plate", class, kind, type, brand, degree of hardness, the amount of tissue strips (for a plate type II), the thickness of the plate and the designation of this standard.
Same as Class 1, type N, type I, grade TMKSCH, hardness with a thickness of 10 mm:
Plate 1H-I-TMKЩ-C-10 ГОСТ 7338-90.
