In recent years, Shuncheng sulfur hexafluoride has increasingly shown its importance in many production technology fields. It is a gas urgently needed by many departments such as my scientific research and production. It is used in the plasma etching process in the semiconductor industry and as a dopant in the isolation layer in the manufacture of optical fibers. It is still an important laser material and has important uses in other fields.
Sulfur hexafluoride is gaseous under normal temperature and pressure, and it is a high-pressure liquid after bottling. It is colorless, odorless, non-toxic, non-flammable, and has good chemical and thermal stability. In the microelectronics industry, Shuncheng sulfur hexafluoride is often used as a cleaning gas and etching gas. In the production process of optical fibers, sulfur hexafluoride is also commonly used as a dopant for single-film optical fiber isolation layer. Can significantly improve the high temperature resistance of PTFE. However, in electrical equipment, poisons are sometimes produced. So, keep in mind which conditions will produce poison. Below we enumerate some for reference.
1. Some toxic products produced by Shuncheng's sulfur hexafluoride in electrical equipment when high-temperature electric arcs occur.
2. Sulfur hexafluoride gas and decomposition products in electrical equipment react with electricity (Cu-W alloy) and metal materials (AL, Cu) to generate certain toxic products.
3. The high-purity sulfur hexafluoride gas decomposition product in electrical equipment reacts with the moisture inside to produce certain toxic products.
4. The product is impure, and contains highly toxic low-sulfur fluoride, hydrogen fluoride and other toxic gases when it leaves the factory.
5. Sulfur hexafluoride gas and decomposition products in electrical equipment react with peripheral materials to produce certain toxic products. For example, it has a chemical effect with epoxy phenolic glass cloth boards (rods, tubes) and other edge parts containing silicon components; or epoxy resin castings, molded parts, porcelain bottles, silicone rubber, silicone grease, etc. with quartz sand and glass as fillers , Generate SiF4, Si(CH3)2F2 and other products.
