Since powder coating spraying technology entered the coating industry, the market share of powder coatings in general industrial coatings has continued to increase year by year. The reason is that powder spraying technology has unique advantages.
Powder spraying room,Reduce environmental pollution
With the environmental protection law becoming more and more stringent on the content of organic volatiles (voc) in the atmosphere, the coating industry has been trying to develop coating technologies that are milder to the environment. After long-term research and experiments, it has been discovered that "electrostatic powder spray "It is the cleanest coating technology currently available.
Significant economic benefits
Among the components of the coating film, the solvent type is about 60% to 65%, and the powder coating can reach almost 100% efficiency, and the powder that is not attached to the object to be sprayed can be recycled and reused. Under normal circumstances, the use of powder spraying technology can make the coating operation as economical and effective as possible.
Energy saving
Because powder coatings do not produce organic volatiles, the waste caused by volatilization into the atmosphere is avoided, so compared with liquid coatings, energy costs are greatly reduced.
Excellent film performance
As long as the powder coating is directly sprayed on the surface of the pre-treated MDF board and baked, the surface of the coating film with excellent performance can be obtained.
Advantages of spray paint
The leveling of spray paint is better than that of spray paint. This is because the molecular structure of the additives and solvents used in spray paint will help the leveling, and spray paint does not have these components.
Spray paint can be repaired in a small area, but spray paint is not. The flexibility of spray paint is better than spray paint, so spray paint can be bent in a small size.
The spray paint is rich in decoration, and the delivery time is fast. It can be customized or produced in small batches.
The spray must be baked at a high temperature, so the adhesion will be better, but there will be requirements for the product size, too large to be put in the oven, and spray paint does not require the size of the product, and can be sprayed on a large area.
Therefore, spray paint and spray plastic cannot be said to be better than each other. It is necessary to adopt a suitable spraying process according to different product requirements.
