Common high-temperature cables will be wrapped in a layer of "rubber protective layer", when such a protective layer is damaged, high-temperature cables will be damaged, so that can not continue to use, so manufacturers will do anti-aging treatment of the rubber protective layer on the periphery, this process involves antioxidants.
1. aging properties
Because of the different characteristics of each antioxidant, the aging properties of different rubber formulations are different. Therefore, the most effective antioxidant for an oak may be ineffective or even harmful to another rubber. Therefore, the selection of antioxidants must be in accordance with the aging properties of various rubber, anti-aging requirements and the characteristics of various antioxidants overall consideration, reasonable choice.
2. and use
When an antioxidant is difficult to meet the requirements, two or more antioxidants should be used together to produce a coordinated effect to ensure the anti-aging effect.
Some antioxidants are coloring and polluting the rubber. Generally speaking, phenolic antioxidants are poorly protected, but they do not pollute or pollute little. The amine antioxidants with high protective effect will cause rubber pollution and serious discoloration. These contradictions should be considered as a whole when choosing.
The dosage of antioxidant should not exceed the solubility in rubber, so as to prevent frosting and pollute the surface quality of rubber.
Amine antioxidants have an adverse effect on the scorching of rubber, phenolic antioxidants can delay vulcanization, and attention should be paid to the selection. As an important protective measure for high-temperature cables, the treatment of rubber protective layer by antioxidants needs attention. Only with solid protection can we further ensure the service life of high-temperature cables and resist the erosion of various hazards.
