Dry powder enamel is the abbreviation of electrostatic dry powder automatic adsorption process, also known as electrostatic enamel. The enamel powder is electrostatically sprayed, adsorbed on the metal surface, and then sintered at a high temperature of 800°C or higher, so that the expansion coefficient of the enamel powder and the steel plate can be close to the same. The biggest advantage of dry electrostatic enamel coating is that the utilization rate of enamel can reach 97%~98%. The enamel dry powder can be used directly without grinding the glaze slurry. high.

Dry powder enamel is expensive.

(1) Dry powder enamel

The service life of dry powder enamel is 2~3 times that of ordinary wet enamel, but the cost is also 2 times. The equipment of dry powder enamel is expensive and suitable for powerful enamel manufacturers. Dry powder enamel is a high-quality advanced process, generally used in enamel ovens, water heaters, microwave ovens, washing machines and other household appliances, and gradually extended to kitchen utensils and wall panels.

(2) Wet enamel

Enamel powder and other raw materials are ground into enamel glaze slurry with water, and then enamel is applied to the surface of the casting and then sintered at high temperature. Because the liquid spraying process is not like electrostatic spraying, it is easy to flow unevenly, and it will cause enamel defects such as blasting in case of shocks. However, the investment in equipment is small, the price is cheap, and the production is simple. The enamel products made by this process are often used in enamel products such as daily necessities and decorations.

Which is better, enamel or stainless steel

1. 304 stainless steel: 304 stainless steel is a common material in stainless steel. It has a high temperature resistance of 800 ° C, and has the characteristics of good processing performance and high toughness. Compared with ordinary stainless steel, it has better heat resistance, corrosion resistance and lead content. lower; hence the name food grade stainless steel.
