Information

Electrostatic dry enamelling is known as one of the greatest achievements of the enamelling process. It was first put into practical use in advanced countries in Europe and America, and then popularized in Japan, Spain and other countries. As we all know, electrostatic dry enamel coating requires high equipment, and the equipment cost is higher than traditional wet enamel coating. Even so, in China, there are still many large-scale enamel factories producing high-end products who choose to use electrostatic dry enamel coating. why?

1. Simple process is the development trend of the enamel industry

Throughout the history of enamel development, the progress of enamel technology is influenced by other industries on the one hand, such as the improvement of iron and steel smelting technology and the advancement of chemical technology, which continuously stimulate the progress of enamel manufacturing technology; on the other hand, it is affected by the needs of the times. Influence, in the past, the enamel industry pursued high quality, high purity and low price, but today, it pursues production efficiency, specialization and refinement development.

The electrostatic dry enamel coating method uses the enamel dry powder directly without grinding it into a enamel slurry, omitting the drying process after ball milling and spraying, and has a high degree of mechanization, so it is popular in large enamel factories. The enamel production line using dry electrostatic coating has been extended to microwave ovens, dishwashers, water heaters, washing machines and other household appliances or kitchen utensils wall panels, etc., and will continue to be popular in the future.

2. The enamel factory itself has brand strength

Dry electrostatic spray enamel system includes electrostatic spray gun, elevator, powder supply barrel, material supply and return system, filter screen, magnetic separation device, spray booth, recovery system, etc. The cost of a set of equipment is high and not suitable for small cost batches Production. However, for powerful enamel manufacturers, the use of electrostatic dry enamel coating is more suitable for production in the long run, which can improve the utilization rate of enamel, reduce raw material costs, improve product quality and pass rate, and reduce product defects.

3. The advantages of electrostatic dry method are outstanding

In addition to the above advantages, the advantages of dry electrostatic enamel coating are: it can improve the quality of the porcelain surface of the enamel product and reduce the defects of the porcelain surface at the edge; two enamels and one firing process can be used, and there is no need to use special decarburized steel plates for enamel, etc. .

Dry electrostatic spray enamel has high requirements on the accuracy of the particle size of the porcelain powder and the thickness of the porcelain layer.
