At present, due to the rapid industrialization of domestic cities, many industries are now emerging. With the development of many industries, the raw material downstream products industries used in these industries have also been promoted, such as the sodium sulfide industry. Nowadays, there are many upstream industrial chains of sodium sulfide, so the application of sodium sulfide is also quite extensive, and since the production technology of the sodium sulfide industry is also constantly innovating, the purity of the extracted sodium sulfide products is now higher and higher, making sodium sulfide products Not only for industrial applications, but also for other industrial applications.

   Sodium sulfide is an inorganic salt product and is an important chemical raw material for industry. Today, sodium sulfide is widely used as a raw material for the production of various corrosion inhibitors and sulphur dyes. It is also used in the papermaking, textile, mineral processing, surface treatment and other industries. Among them, it is mostly used in the tanning industry, mainly because sodium sulfide has significant effects and economic benefits on the peeling and enamel of leather products. Moreover, many factories use other chemical additives to compare sodium sulfide. The reaction of sodium sulfide is better than other chemical additives, and the price is low, so the comprehensive treatment cost is also low, which is also the sodium sulfide. The reason for favor.

   Nowadays, as sodium sulphide has a place in many industries, the market for sodium sulphide has also been rising, and sometimes it has caused insufficient supply of market demand. As a result, the domestic sodium sulphide production base is gradually growing, but now With the stricter requirements of environmental protection laws, the sodium sulphide industry is also limited in terms of sunrise quality. Therefore, the research on new product production technology of sodium sulfide industry is also aimed at reducing and reducing the development of environmental pollution, which has great practical significance for environmental protection. .
