Ozone aging test chamber for testing vulcanized rubber products, organic materials, non-metallic materials, ozone aging resistance and aging cracking tensile test.
Rubber and rubber products in the molding process, long-term storage and use of the process, due to oxygen, ozone, variable metal ions and other chemical substances, combined with mechanical stress, light, heat, high energy radiation and other physical factors, Soften sticky, or harden crisp, crack, physical degradation. This phenomenon is called aging.
The reasons why rubber (including raw rubber and vulcanized rubber) suffer aging is the internal factors of rubber macromolecules exist in the weak bond, so it is vulnerable to oxygen invasion, thus destroying the structure of the original rubber; and external factors that the chemical, physical Factors accelerate the aging of rubber. However, the basic reason is the oxidation.
Common types of rubber aging
Light oxygen aging
Harmful metal aging
Variable metal ions
Oxygen + deformation
Flexion, mechanical damage
From the above analysis we can see that the aging of rubber is mainly under different conditions of oxidation and ozonation.CLIMATE INSTRUMENT CO.,LTD has over 10 years of industry experience in designing and manufacturing environmental chambers and temperature controlled products.
