Problems solved by technology

However, almost all plastics are now insulators, which are prone to static electricity, and in some cases can generate thousands or even tens of thousands of volts of static electricity
It is precisely because of the physical characteristics of plastics that people use plastic products to bring many problems, hidden dangers, losses and even disasters. For example, the electromagnetic field generated by static electricity is like a vacuum cleaner, which makes plastic products easy to absorb dust and affects normal production. , leading to product appearance defects; another example, in petrochemical, mining and many other industries, static sparks will cause explosions. If not handled and controlled in time, plastics with static electricity are like invisible bombs that may detonate at any time. Therefore, today Effective antistatic plastics are required in many fields
[0003] The antistatic plastics with migratory chemical antistatic additives or conductive fillers are traditional antistatic plastics, but plastics with migratory chemical antistatic additives have short service life, cannot work in low humidity environments, and The characteristics of migration will pollute the product and the surrounding environment; another kind of plastic that adds conductive fillers or conductive metal fibers will also pollute the product or the environment, and the color of this type of product is dull, and it is difficult to deploy a variety of colors. Due to the characteristics of excessive discharge of the product, it may cause explosion in some occasions
