The ozone content in the atmosphere is very small but it is the main factor for rubber cracking. The ozone aging test chamber is a simulated and strengthened large-scale rubber product exposed to air and constant temperature test chamber with constant ozone concentration and exposed to closed and non-light, according to the predetermined time Test the samples, study the effect of ozone on rubber, quickly identify and evaluate the anti-ozone aging performance of rubber and the protective effect of anti-ozone agent, and then take effective anti-aging measures to increase the service life of rubber products.
The equipment used to test the ozone aging resistance of rubber and its products implements (meets) relevant standards: GB / T7762-2003 vulcanized rubber or thermoplastic rubber ozone cracking static tensile test method. GB / T2951.21-2008 General test method for cable insulation and sheath materials. And the test methods specified in other relevant standards. Brief description of GB / T7762-2003 standard of rubber aging test box:
