With the continuous development of science and technology, people are increasingly aware of the advantages of electrostatic powder enamel spraying technology, and the fields of application are also constantly expanding.

Electrostatic powder enamel spraying is a new enamel coating process developed in the 1970s. It is currently one of the most advanced enamel coating technologies in the world. The main principle is: with the help of compressed air, the enamel powder is transported through a pipeline to a negatively charged high-pressure spray gun, so that it is sprayed out with a negative charge and is adsorbed on the surface of the grounded iron blank, thereby forming a uniform enamel powder layer. After firing, an enamel composite product with a delicate and smooth porcelain surface is obtained.

Compared with traditional wet enamel coating, the electrostatic powder enamel coating process has the following three major advantages:

1. Spraying of enamel products does not require grinding or preparing enamel slurry; no other grinding additives are added, only an electrostatic powder; no waste and wastewater treatment are required;

2. The enamel coating process is based on electrostatic adsorption, and the spray chamber can be integrated with the pretreatment process; it can be fully automated to achieve high production capacity and efficiency; the enamel powder is almost 100% recycled; because the product is dry powder, no drying device is required ;

3. The surface quality of the final enamel product is excellent. After spraying, it is sent directly to the firing conveyor, so there is no dust pollution; the surface is very smooth and the spraying thickness is uniform; the spraying is complete because the edges are also covered; there is little reprocessing, so there is no The enamel coating is ultra-thick, and the bubble structure of the enamel layer is stable and regular.

Based on the advantages of electrostatic powder enamel spraying and the continuous improvement of dry powder technology, such as the further development and improvement of spray guns, complete sets of equipment and enamel processes, the practical application capabilities of electrostatic powder enamel spraying continue to improve, and the application scope of electrostatic powder enamel spraying is increasing. The wider range: enamelware, enamel water heater liner, enamel building slab, enamel oven liner, enamel grill and grill, enamel exchanger, enamel assembly tank, enamel granary, etc.
