Problems solved by technology

There are many defects in vulcanization and cross-linking: if a 100-meter-long sulfur pipe is required, the production energy consumption is high and the speed is slow, scorching is prone to occur during the production process, and exhaust gas pollutes the environment
Irradiation cross-linking electron accelerator equipment is expensive, covers a large area and has high maintenance costs, and the radiation produced is not conducive to environmental protection
