Features of Dynamic ozone aging test chamber
1. The content of ozone in the atmosphere is very small, but it is the main factor for rubber cracking. This product simulates and strengthens the ozone conditions in the atmosphere, studies the effect of ozone on rubber, and quickly identifies and evaluates the anti-ozone aging performance and anti-ozone properties of rubber. Method for the protective efficacy of the agent. Reference standards: GB/T7762-2003 vulcanized rubber or thermoplastic rubber ozone crack resistance static tensile test method, GB/T2951.21-2008 General test method for cable insulation and sheathing materials, GB/T 11206- 2009 Rubber aging test surface cracking method, and test methods specified in other relevant standards.
2. Principle and method - The test method can be divided into "static" and "dynamic" according to the test method and standard. Static means that the sample is placed in the test box for testing after being stretched, and dynamic means that the sample is placed in the test box. On the fixture, the test is performed while stretching, and the tensile fluctuation is about 5%-45% of the tested sample itself.
