Large Weathering Accelerated Ozone Aging Test Chamber for Plastic Rubber
The ozone aging test chamber 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 of rubber and the method of anti-ozonant protection. It is suitable for the aging test of non-metallic materials and organic materials (coatings, rubber, plastics, paints, pigments, etc.) under ozone conditions.
Features:
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.

Equipment summary:
Ozone is a major factor in rubber cracking although it is rare in the atmosphere, rubber ozone aging testing chamber oven simulates and enhance the condition of ozone in the atmosphere to study the effects of ozone on rubber, and
then identify and evaluate the method to resist ozone and aging for rubber, adopt effective anti-aging measures to enhance the life of rubber products.
