Zinc series (spray)-office furniture

The zinc series (spray) used in office furniture usually refers to zinc series phosphating spray, which is a chemical process commonly used in the surface treatment of office furniture. The following is an introduction to the principles, advantages, process flow, etc.:

principle

Zinc phosphating spray uses phosphate solution to react chemically with the metal surface of office furniture to form an insoluble phosphate conversion film on its surface. This film is mainly composed of zinc phosphate and its hydrate, which can improve the corrosion resistance, wear resistance and coating adhesion of the metal surface.

advantage

Good corrosion resistance: The zinc phosphating film can effectively isolate the metal from the contact with moisture, oxygen and other corrosive media in the external environment, thereby slowing down the corrosion rate of the metal and extending the service life of office furniture.

Enhance coating adhesion: The phosphate film has a porous microstructure, which can increase the roughness and specific surface area of the metal surface, so that the subsequent coatings such as paint and powder coating can better adhere to the metal surface, improve the adhesion and bonding force of the coating, and reduce the phenomenon of coating shedding and peeling.

Low cost: Compared with some other surface treatment methods, such as electroplating, the cost of zinc phosphating spray process is relatively low, the equipment investment and operating costs are not high, it is suitable for large-scale industrial production, and can reduce production costs while ensuring product quality.

Good environmental performance: Zinc phosphating solution usually does not contain harmful substances such as heavy metals. The wastewater, waste residue and other pollutants generated in the production process are relatively small. After proper treatment, they can meet environmental emission standards and cause less pollution to the environment.
