What is the prospect of metal surface treatment technology?

According to statistics, domestic products suitable for chemical surface treatment of metals include fasteners for power, transportation and machinery, plumbing fittings, nails, cement nails and chain links. (about 2 million tons per year). At present, the actual output of mechanical electroplating is only about 6.5438 million tons per year, and it is mainly processed and exported. With the development of the market, the requirements for metal surface treatment are getting higher and higher. In the surface treatment of quite a few kinds of workpieces, the metal chemical surface treatment technology will definitely replace the traditional electroplating and hot dip galvanizing technology. Moreover, the hardware products in industrialized countries are gradually developing to high and medium-grade products, and the middle and low-grade hardware products have been transferred to developing countries for production. Compared with Indian, Korean, Vietnamese and other countries, China has greater market potential, including domestic and processing export markets, and is gradually developing into a major country in hardware processing and export in the world. In recent years, with the development of chemical surface treatment technology of metals in China, the domestic processing volume entrusted by foreign countries has increased year by year, which is distributed in Sichuan, Zhejiang, Henan, Hebei and coastal provinces. It can be seen that the chemical surface treatment process of metal has a huge development space in China, while the foreign mechanical zinc plating equipment and raw materials are expensive (the whole set of equipment is 420 thousand US dollars) and the process is complex, which creates a good development opportunity for the domestic mechanical zinc plating technology and equipment.

With the enhancement of people's awareness of environmental protection and the implementation of environmental protection laws and regulations, the development of traditional zinc plating technology will be limited. Mechanical zinc plating technology belongs to "green" surface treatment technology, which has good social and economic benefits and good application prospects.
