Problems solved by technology

[0002] Anti-termite, anti-mouse, durability and corrosion resistance are long-term problems to be solved in the field of wire and cable. In the past, various additives such as dieldrin, aldrin or chlordane were used to prevent termites. However, these additives volatilized A large number of irritating and toxic gases pollute the human body and the environment greatly. Therefore, nylon materials are used internationally to prepare wire and cable sheaths to achieve the purpose of preventing rodents and ants. Nylon has high insulation and strong hardness, which can Resistant to termites, and nylon-sheathed wires and cables made of nylon are durable and corrosion-resistant
However, at present, the research and application in this area in our country is not mature.
