The content of ozone in the atmosphere is very small but it is the main factor of rubber cracking. This product simulates and strengthens the ozone conditions in the atmosphere, studies the law of the effect of ozone on rubber, and quickly identifies and evaluates the ozone resistance and aging resistance of rubber. The method of anti-ozonant protection efficiency. Reference standard: GB/T7762-2003 vulcanized rubber or thermoplastic rubber anti-ozone cracking static tensile test method, GB/T2951.21-2008 cable insulation and sheath material general test method, GB/T 11206-2009 Rubber aging test surface cracking method, and other test methods specified in related standards.
Principles and methods
test methods can be divided into "static" and "dynamic" according to test methods and standards. Static means that the sample is stretched and placed in the test box for testing, while dynamic means that the sample is placed in the test box. On the fixture, do the test while stretching, and the fluctuation of the stretching is about 5%-45% of the tested sample itself
