Bio-preservation technology apply in many fields such as ammonia-free rubber

This project intends to replace the ammonia water with the self-developed and patented nano-preservation technology formula in the rubber milk processing process, so as to fundamentally solve the harm of harmful substances in natural rubber and ammonia nitrogen (high nitrogen wastewater) to the water source environment. Pollution. At present, all of the world’s natural rubber milk preservation uses ammonia water,

What is the role of magnesium oxide and zinc oxide in rubber?

Magnesium oxide and zinc oxide in the rubber is mainly to play a liquidity and antioxidant capacity, increase the tensile strength of rubber and impact resistance. Second, the reaction of zinc oxide as an active agent with an organic accelerator, stearic acid, sulfur and the like occurs during the vulcanization process on the surface of the zinc oxide particles. Due
