*The generation of static electricity and the basic principle of antistatic
Almost any static electricity is created by friction. For example, a plastic bag rubs against the surrounding air (wind, airflow, or movement of the plastic bag), causing static electricity on the surface of the plastic bag:
The friction between plastic bags and equipment during production.
Since the plastic itself is a good insulator, the static electricity generated by friction can accumulate on the surface of the plastic bag and generate a relatively high voltage. The voltage can be hundreds of volts, or in some cases, even as high as several thousand volts. Therefore, for the electronics industry, almost all plastic packaging bags must have antistatic functions. Otherwise, electronic products will be easily destroyed by the static electricity carried by the packaging plastic bags. For plastic bags used for fast automatic packaging, static electricity will cause the "adhesion" of the plastic bags on the equipment, affecting the normal operation of the equipment. For general packaging plastic bags, it will absorb dust

*Basic classification, working principle and efficacy of antistatic agents
① antistatic agents are basically divided into two categories: 1) conductive substances; 2) moisture adsorption antistatic agents in the air.
1) Conductive substances include carbon black, carbon fiber, stainless steel microwires, conductive polymers, etc. These substances can make plastics have permanent antistatic properties, and at the same time, they can also make plastic materials have different levels of antistatic properties due to the difference in the amount of added people, and even make the added plastic materials into electrical conductors.
2) The moisture adsorption antistatic agent in the air is a polar compound with a hydrophilic group. They all have a tendency to penetrate into the surface of plastic materials. When it penetrates into the surface of the plastic material, its hydrophilic polar groups can adsorb the moisture in the surrounding air to the surface of the plastic material, so that the resistivity of the surface of the plastic material is reduced, so static electricity is eliminated.
*Antistatic agent commonly used in antistatic masterbatch:
(1) Monoglyceride stearate
English name GlycerylMonostarate, GMS
GMS is a typical product of polyol fatty acid ester nonionic antistatic agent. As an additive antistatic agent, it is suitable for polyethylene, polypropylene, polyvinyl chloride and other products, with high thermal stability, relatively durable antistatic properties and good cost and performance balance
(2) Antistatic agent KJ-210 (NN-Bis(2-hydroxyethyl)fatty Amide and Ester)
KJ-210 is an alkanol amide type non-ionic antistatic agent, suitable for polyethylene, polypropylene, polystyrene, soft PVC and other products, with thermal stability, outstanding antistatic effect, no blooming, volatile Small size and good durability. Since it is non-corrosive to electronic packaging, it has the potential to replace amine antistatic agents in the application field of electronic equipment packaging products. This product is non-toxic and can be used in food contact materials.
(3) Antistatic agent HZ-1
Antistatic agent HZ-1
use. This product is a non-ionic additive antistatic agent. It is mainly used in polyethylene, polypropylene and other plastic products. It can reduce the surface resistivity of plastics from 1016Ω•m to 109~1Ω•m. This product is basically non-toxic and can be used in food and Medical Packaging Materials
