Two test methods of rubber low temperature brittleness tester

One, rubber test equipment aging performance test method



1, hot air aging test under the action of atmospheric pressure, constant
temperature and hot air, after a certain time, measure the change of physical
and mechanical properties of the sample, used to measure the thermal stability
of rubber and the performance of antiaging agent.



2, the test of oxygen aging measurement sample in the closed oxygen inhalation
apparatus in the oxygen induction period and oxygen absorption speed, used to
evaluate the rubber resistance to oxygen aging properties, study the dynamics of
the oxidation process, evaluate the effectiveness and optimal dosage of
antiaging agent.



3, artificial climate aging test simulation and strengthening of sunlight, heat,
rain, temperature and other factors in the atmosphere, in order to obtain in the
shortest time similar to the results of atmospheric aging test method.



Two, rubber test equipment low temperature performance test method



1. Torsion modulus test by measuring the torsion Angle of rubber at different
temperatures, calculate the change of its torsion touch, to measure the degree
of rubber rigidity increase at low temperature.



2, glass temperature test to determine the temperature of rubber from high
elastic state to glass state transformation, that is, glass temperature. It can
characterize the ultimate service temperature of rubber material (the lowest
operating temperature)
