3 Test principle
The yarn dipped or dipped tire cord fabric and rubber, respectively, according to certain rules in a certain order blanks into the sample mold, after vulcanization prepared to become
Sample. Using tensile testing machine at a constant speed between the peeling layer and rubber fabric sample was measured during the peeling of the peel force peaks
Value, this value is the adhesion peel force measured or dipped tire cord fabric and yarn dipped vulcanized rubber; peel adhesion force and the specimen width ratio of test
Kind of bond peel strength; rubber sample after stripping effective coverage and effective peeling rubber coverage area ratio of samples; determined by the rules
And indicating the position set after the release of the destruction of the sample.
4 instruments and equipment
4.1 tensile testing machine
This standard uses constant elongation (CRE) type tensile testing machine, testing machine should meet the following technical requirements.
a) the use of electric drive and equipped with a suitable non-inertial force measuring device (such as electronic type or optical type);
b) a holder holding the sample, during the test, two gripping surfaces of the holder should be in the same vertical plane;
c) There may be a method in accordance with GB/T 12833 stipulated the test data recording and processing of computer hardware and software systems.
4.2 tensile testing machine holder
The holder shall meet the following requirements.
a) the movable holder moving at a constant speed, speed variation should be less than 4%;
