If not treated directly into the atmosphere , it will cause great harm to the air pollution and biological and environmental . Toxic organic solvents is large, inhaled, will harm people's respiratory , nervous system and hematopoietic systems. A large number of mist particles generated during the production of the coating is wet dust, which contains all of the coating composition, such as pigments, resins, organic solvents and other auxiliary materials . These chemicals enter the body would endanger the respiratory tract , lungs, stomach and other organs , can cause lead poisoning . Organic solvents and paint particles will damage the skin , but also enter the body through the skin , causing harm.
We say that the use of the painting process is higher than the risk of fire spray process, based on the following three reasons: First, because the paint contains volatile organic solvents, in the construction and coating curing process , the overflow of organic solvents accumulate in the air to a certain concentration , once contact with fire ( sparks, Mars ) , it is easy to cause a fire and explosion, and powder coating composition does not contain organic solvents , it is less dangerous than the painting process ; followed by ignition of paint , flash point, Finally, the method using a conventional air spray painting a workpiece ; powder coatings were lower than the ignition energy , fast burning powder coating diffusion , and therefore under the same conditions , the risk of fire and explosion process than spray painting process either ventilation or construction environment and the rules are inferior to the spray process, and therefore the risk of fire former than the latter. It should be particularly noted that despite the fire risk is higher than the spray painting process technology , but once the powder coating exploded, its strength and destructive explosion will be greater than liquid coatings.
