Problems solved by technology

However, the insulation resistance of nylon is very high, generally higher than 10 14 Ω, in the process of use, nylon is easy to accumulate a large amount of electrostatic charge after contact or friction with other materials, which is easy to cause electrostatic discharge, resulting in fire, explosion and other accidents, which greatly limits its application in coal mines, chemical equipment, textile machinery parts, electronic appliances, etc. Promotion and application in other fields
In order to eliminate the electrostatic hazard of nylon itself, some antistatic agents such as conductive carbon black and conductive zinc oxide are usually added. However, the addition of a large amount of antistatic agents tends to weaken the mechanical properties of nylon composites. In addition, the added antistatic The agent will gradually precipitate out during long-term use and cannot achieve durable antistatic properties, which are not conducive to the wider application of nylon composite materials
