Technical plates of TMKShch, MBS, AMS GOST 7338-90 are intended for production of the rubber products serving for consolidation of motionless connections, prevention of friction between metal surfaces for perception of single shock loadings, and also as laying, floorings and other sealing connections.
Technical plates of TMKShch, MBS, AMS depending on appointment, a design and a way of production let out the following:
TMKShch - teplomorozokislotoshchelochestoyky;
AMS - atmosfero-oilproof (restrictedly ozonostoyky);
MBS - maslobenzostoyky.
class 1: the plate of TMKShch, MBS, AMS from 1 to 20 mm thick intended for production rezino-the technical products serving for consolidation of the knots working under pressure of higher than 1 MPA (10 kg/cm2, 10 atm);
class 2: the plate of TMKShch, MBS, AMS intended for production from 1 to 60 mm thick of the rubber products serving for consolidation of the knots working under the pressure up to 0.5 MPAS (5 kg/cm2, 5 atm) for prevention of friction between metal surfaces and also for perception of single shock loadings or as linings, floorings.
Ф - shaped plates of TMKShch, MBS, AMS: the curing produced by method in compression molds on vulkanizatsionny pressa, thickness from 3 to 80 mm., the size is 250*500 mm., 500*500 mm., 720*720 mm.
N - not shaped rolled plates of TMKShch,MBS, AMS: made by means of expression of rubber mix via dies with the subsequent curing without forms in coppers, and also on vulcanizers of continuous action, thickness from 1 to 20 mm., width 800, 1200 mm., length is from 1200 mm.
type I: rubber technical plate (TMKShch, MBS, AMS brands);
type II: a rezinotkanevy plate with one or several fabric layers (on each 2 mm. plates there have to be no more than one fabric layer).
degrees of hardness of TMKShch, MBS, AMS:
M - soft: (hardness on ShORu of 35-50 units);
With - average: (hardness on ShORu of 55-65 units);
T - raised: (hardness on ShORu of 70-80 units).
Marking of a technical plate example: 2-H-I-TMKShch-S-5 GOST 7338-90
The 2-first figure – a class, speaks about technical plate service conditions
1 - under pressure of over 0,1 MPas,
2 - it is lower than 0,1 MPas;
- H-a letter F or H – a type of a technical plate:
H – not shaped (rolled)
Ф – shaped (sheet)
- I-the Roman figure I or II – type of material of which the technical plate is made:
type I – a technical plate rubber
type II – a technical plate rezinotkanevy (rubber with fabric laying)
TMKShch brand of rubber which characterizes the environment of application of a technical plate:
TMKShch – warm morozo-kisloto-alkaliproof
MBS – maslobenzostoyky
AMS – atmosferomaslostoyky
- With - the letter C, M or T specifies on strepen technical plate hardness on ShORu:
With – average, 55-65 pieces.
M – soft, 35-50 pieces.
The t – increased 70-80 pieces.
- The 5th last figure speaks about its thickness in millimeters.
Before the last figure for a rezinotkanevy technical plate the number of fabric laying is specified: for example-1х5
