Zinc series (immersion)-furniture

Zinc system (immersion) is a process commonly used in furniture manufacturing for the surface treatment of metal parts. The following is an introduction to the process principle, treatment process, advantages and limitations:

Process principle

Zinc (immersion) treatment is a surface treatment of furniture metal parts by immersion in a solution with zinc salt as the main component. During the immersion process, the metal surface reacts chemically with the zinc solution to form a zinc phosphate film. This phosphate film has good corrosion resistance, wear resistance and adsorption, which can improve the protective performance of metal parts, and at the same time provide a good foundation for subsequent coating and other processes, and enhance the adhesion between the coating and the metal surface.

advantage

Good corrosion resistance: Zinc phosphating film can effectively isolate the metal surface from contact with air, moisture and other corrosive media, slow down the corrosion rate of the metal, and increase the service life of furniture metal parts.

Enhance coating adhesion: The metal surface after zinc immersion treatment has good roughness and adsorption, which can make the subsequent coatings such as paint and powder coating adhere better to the metal surface, improve the adhesion and durability of the coating, and reduce the phenomenon of coating shedding and peeling.

Relatively low cost: Compared with some other surface treatment processes, the equipment investment and operating costs of the zinc series (immersion) process are relatively low, which is suitable for large-scale production and can reduce the cost of furniture manufacturing to a certain extent.

Good environmental performance: The components in the zinc solution are relatively environmentally friendly, and the wastewater, waste gas and other pollutants generated during the treatment process are relatively small. After proper treatment, they can meet environmental emission standards and have less impact on the environment.
