Prevention of rubber aging deterioration to remove security risks

Tires should be replaced in 3 years / 60,000 km, the longest life of 5 years or 60,000 -8 million km. And the replacement of new tires when the owner must pay attention to the production date, otherwise it will change to the old but old old tires, this will also bring security risks. Tires are rubber products, with the passage of time, the rubber will be aging deterioration. The ...


How to achieve energy saving and environmental protection in the production of carbon black?
