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?
- 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.
- 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.
- 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.

Dry and Wet Powder Enamel, Which Cost Higher?
What kind of production process is used in enamel directly determines the level and quality of the product. The enamel factory will choose the enamel process according to the metal type, shape, and volume quality of the green body. Generally, it is divided into two categories: wet enamel coating and dry enamel coating. So which one costs more, dry powder enamel or wet powder enamel? What are the advantages and disadvantages? How to choose an enamel factory? After reading this article, I believe you will have the answer. (1) Dry powder enamel 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 above 800 °C, so that the expansion coefficient of the enamel powder and the steel plate can be nearly 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 enamel slurry. high. 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 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.
How long does power coating take to dry?
Powdercoat painting is an electrostatic 'dry' form of painting. It does however take in the region of two hours to dry properly, depending on the process used.
Is black acid resistant enamel electrostatic powder ideal for enamel oven and BBQ stove manufacturers?
With the development of enamel technology and the upgrading of enamel products, more and more enamel factories adopt electrostatic dry spraying to improve the utilization rate of enamel. Among them, food contact enamel has high requirements for acid resistance, NOLIFRIT as an enamel glaze factory, hereby introduces black acid-resistant enamel electrostatic powder, specially tailored for enameled ovens, baking trays, pots and pans, barbecue grill grill and other enameled products in direct contact with food to lead the new enamel market with excellent performance. 1、 Good powder properties, shaping beautiful porcelain layers Nolifrit black anti-acid enamel electrostatic powder has good powder properties. Its excellent fluidity ensures uniform coverage during the spraying process, reducing waste; High adhesion speed and strong adhesion enable the coating to tightly bond with the metal substrate, achieving good adhesion even on complex shaped surfaces, giving enamel products a strong and beautiful appearance. 2、 Glazed luster, showcasing quality We are well aware that appearance is the first element that attracts consumers. Therefore, after firing, the dry powder presents a charming black glaze surface, which not only has a uniform and full color, but also has a delicate luster, making every enamel product emit a high-end and atmospheric texture, meeting the aesthetic needs of modern homes and commercial kitchens 3、 Featuring excellent performance and durability, it provides peace of mind Adhesion performance is one of the important indicators for measuring the quality of enamel coatings. NOLIFRIT black acid resistant enamel electrostatic powder ensures a strong bonding force between the coating and the substrate through precise formula design and advanced production technology, effectively resisting wear and impact in daily use, extending the product's service life, and allowing consumers to use it with more peace of mind. 4、 Excellent acid resistance, safeguarding food safety Enamel products made by coating and firing the electrostatic powder with common acidic substances in the kitchen environment, such as lemon juice and vinegar, can have excellent acid resistance. It can effectively resist acidic erosion, protect the substrate from damage, and ensure that food does not come into contact with harmful substances during cooking, comprehensively safeguarding food safety and ensuring that every meal is healthy and worry free.
How long does enamel paint need to dry?
It depends. If it's an oil based enamel, it will take anywhere from an hour, for a super-fast dry enamel which is intended to be sprayed, to 24 hours for a standard coating. A water based enamel with usually dry to the point of being serviceable anywhere from an hour to six hours. This is assuming that the paint was applied at a moderate temperature and with a low relative humidity. Both types of enamels should not be scrubbed for at least two weeks to allow time for the surfaces to fully cure. As always, it's best to check the paint's label or technical data sheet for information specific to that coating.
