The advantages of powder coating powder
1. No organic solvents
So what is powder coating powder? Or a fireproof agent, no organic solvent can avoid the organic solvent brought by fire; it can also avoid poisoning and inconvenient transportation.
2. High utilization rate
Powder coating powder is actually a completely solid system. What is powder coating powder? Closed-circuit circulation system can be used, there is no air pollution, spray powder coating powder can be recovered, the utilization rate is up to 95%.
3, efficient construction
Powder coating powder in the coating, coating thickness can be controlled, a coating thickness, a class to reach 30~500μm, powder coating powder is what? It is equivalent to the thickness of several to dozens of solvent-based coatings, which reduces the number of construction and improves the production efficiency.
4, convenient operation and hygiene
In construction application, it is not necessary to adjust the viscosity with seasonal changes; the construction operation is convenient, does not need very skilled operation technology, thick coating is not easy to produce flow hanging and other film malady; easy to maintain the health of the construction environment, the powder attached to the skin can be blown off with compressed air or washed off with warm water, soap, do not need to use an irritating cleaning agent;
the disadvantages of powder coating powder
1. The manufacturing process of powder coating powder is more complex than that of general coating, and the manufacturing cost of coating is high;
2. The coating equipment of powder coating powder is different from that of general coating. The coating equipment of general coating can not be used directly.
3. The softening point of resin used in powder coating powder is generally required to be above 80℃. In this way, the baking temperature of powder coating powder is much higher than that of general coating. And can not be painted with large equipment and heat sensitive substrate;
4, the replacement of paint color, variety than the general paint trouble. When it is necessary to exchange colors frequently, the economy of production and construction of powder coating powder is seriously damaged, and the cleaning between colors is time-consuming. Powder coating powders are best suited for reasonably long running with powders of the same type and color.
