Become the Trend of Enamel Products?

As a composite inorganic material resistant to acid, alkali and corrosion, enamel is widely used in enamelware, pipes, equipment and other fields. In its manufacturing process, electrostatic dry powder spraying technology has become a major trend in the production of enamel products, and is currently widely used in construction products, household appliances (microwave ovens, dishwashers, water heaters, washing machines, etc.) and kitchen utensils.

The electrostatic dry method is an efficient and environmentally friendly enamelling method. The powder is sprayed on the surface of the object to be coated, and the powder is evenly attached to the surface of the object under the action of static electricity, and then cured under high temperature conditions to form a dense, wear-resistant coating. , Corrosion-resistant porcelain layer. Compared with traditional spraying technology, electrostatic dry powder coating has the following characteristics:

First of all, the electrostatic dry powder coating technology has a high adhesion rate. Due to the existence of electrostatic interaction, the powder can evenly adhere to the surface of the object and form a dense porcelain layer, thereby improving the adhesion and corrosion resistance of the porcelain layer.

Secondly, the utilization rate of electrostatic dry powder enamel is high. In the traditional enamelling technology, the utilization rate of enamel is low, and a large amount of paint is often sprayed into the surrounding environment, resulting in waste of resources and environmental pollution. The electrostatic dry powder coating technology can directly contact the enamel powder with the surface of the object, reducing the splash and consumption of the enamel powder and improving the utilization rate of the enamel.

Thirdly, the luster and acid resistance of the porcelain layer have been improved after the electrostatic dry powder coating and firing. Since the powder particles are evenly attached to the surface of the object to form a dense coating, the product coated with electrostatic dry powder has a smooth and uniform appearance, and is not prone to bubbles, sags and other phenomena. This spraying technique improves the aesthetics and quality of the product.

Finally, the electrostatic dry powder coating technology has good environmental performance. The powder used in this technology can be reused, which reduces the discharge of paint waste and meets environmental protection requirements.

With the continuous development of the enamel product market and the improvement of consumers' requirements for product quality, enamel manufacturers have moved from low-end to high-end, using electrostatic dry powder coating technology to produce high-quality products.

If the enamel factory wants to switch to electrostatic dry spraying, it needs to purchase related equipment, such as electrostatic spray guns, elevators, powder supply barrels, material supply and return systems, spray booths, etc. The equipment is relatively large and the price is not low. At the same time require the staff to master the relevant spraying technology. Hunan Nolifrit is a manufacturer of enamel frits and inorganic pigments. If any enamel factory needs electrostatic dry powder or wants to adopt electrostatic dry method and needs relevant technical support, please contact Hunan Nolifrit.
