In recent years, the development speed of powder coating is quite amazing, under the environmental pressure of chemical industry depression, still maintain the growth rate of about 10%. This is naturally closely related to the characteristics and advantages of powder coatings. Under the traction of environmental protection requirements and technological innovation, it provides sufficient power for the rapid progress of powder coatings.
Low temperature curing powder coating
Curing conditions for powder coatings are usually harsh. Usually, they need to bake at 180-200 for 10-15 minutes. The baking temperature of low-temperature curing powder coating is about 150. The higher the baking temperature, the longer the time, the lower the efficiency.
Reducing the curing temperature of powder coating can not only accelerate the production speed of automatic production line, improve production efficiency, but also make powder coating applied to composite materials, wood, plastic and other heat-sensitive substrates.
Therefore, the realization of low temperature curing can effectively save energy, improve work efficiency, expand the application field, is one of the important development directions of powder coating.
Thin powder coating
Film thickness is an important factor to determine the appearance of powder coatings.
At present, the standard film thickness of powder coating powder manufacturer in our country is 60-80m. For some products that only need 30-40m film thickness, the performance of thick coating is too high, which increases the cost. Therefore, thin coating is one of the important development directions of powder coating.
Coil powder coating
With the increasingly stringent environmental protection requirements and cost-benefit factors of the country, coil coating powder will be gradually recognized by people and become the development trend of coil coating.
Functional powder coating
Functional powder coating refers to surface coating materials with special functions and special uses.
It can not only play the traditional role of protection and decoration, but also give materials a variety of special functions. This powder coating can be a high wear and scratch resistant coating with fine structure and matte color, or a coating with rough surface structure but good masking properties for concave and convex defects on the substrate surface.
The technology level of functional powder coating in China is still far behind the advanced level abroad. It is one of the directions to be overcome in the future.
Fine art powder coating
Art powder coating is a kind of paint with special art decoration. Fine art granular powder coatings suitable for indoor and outdoor use in a variety of complex environments can mask substrate defects or enhance the image of sprayed substrates.
Fine art powder coating has high requirements on the appearance, uniformity, stability and reproducibility of the pattern.
Heavy anticorrosive powder coating
Heavy anticorROsive coating is mainly anticorROsive, with excellent mechanical properties and acid resistance, alkali resistance, solvent resistance, heat resistance and other anticorROsive properties. It is mainly used for oil pipeline, ship, construction steel bars, storage tank and so on.
Water-based powder coating
The powder paint is dispersed in water, then additives are added and filtered to form a suspension. These additives have little effect on the properties of the final coating.
Imitation electroplating effect powder
High simulation electroplating products have high requirements for powder production and use. Any negligence will lead to defects in the paint film.
At present, the defects of Bunding technology, metal powder and powder appearance make the imitation electroplating powder still have a certain distance from the actual electroplating product. However, due to the country's increasingly strict environmental protection, environmental protection technology products will have a broader market space.
