What hazards can static electricity generate? At present, with the rapid development of technology, various industries are prone to static electricity, and both the plastic industry and other industries may be harmed by static electricity.

The harm of static electricity: Static electricity is a static state of charge. Static electricity can occur during the dissociation and separation, friction, deformation, and ion attachment of two objects.

There are many hazards of static electricity, which can be roughly divided into two parts.

The first type of electrostatic hazard: originating from the interaction of charged bodies. When the aircraft body rubs against particles such as air, dust, and water vapor, it can become electrically charged. If measures are not taken in a timely manner, the aircraft's radio equipment will malfunction, and static electricity in the printing factory will cause paper to bond, making it extremely difficult to separate and causing trouble for printing

The second type of electrostatic hazard: Explosion occurs due to the ignition of flammable materials by electrostatic sparks. Sparks generated by static electricity are generally harmless to the human body, but when the air is filled with flammable gases and dust, electric sparks can cause a powerful explosion. In coal mines, gas explosions can occur, leading to worker death or injury, and the mine being scrapped; The main component of anesthesia on the operating table is ether, and electrostatic sparks can cause the anesthetic to explode, causing harm to doctors and patients.

Definition of antistatic agent: antistatic agent is a kind of chemical additive added to the resin or coated on the surface of polymer materials to prevent or dissipate static charges. It does not have free moving electrons and belongs to the category of surfactants. It forms a leakage charge channel through the conduction or hygroscopic action of ionized genes or polar groups, achieving the purpose of anti-static.

The classification of antistatic agent can be divided into: surfactant antistatic agent (cationic antistatic agent, anionic antistatic agent, zwitterion antistatic agent, non-ionic antistatic agent), conductive filler antistatic agent.

Development trend of antistatic agent

The development of optoelectronic technology The development of antistatic agents puts forward new requirements. In addition to antistatic properties, they should also have good mechanical properties. In recent years, some harmful solvents with high irritation and toxicity are being replaced by safety guards, low toxicity or non-toxic products. These products have long-term antistatic properties, are basically non-toxic, and have no surface precipitation, so they will not cause surface pollution, and will become a hotspot in the future research of antistatic field.

Due to the high processing temperature of plastic antistatic agent and plastic, many antistatic agent will decompose and produce harmful gases. In order to solve this problem, it is necessary to develop high heat resistant antistatic varieties.
