The transfer efficiency of traditional air spray guns (i.e. paint utilization rate) is about 30%, and about 70% of spraying solvents are dispersed into the surrounding environment with the flying mist, which wastes a lot of paint or coatings, which not only increases economic costs, but also TVOC, The emission of toxic and harmful substances such as benzene and formaldehyde is very large, which seriously pollutes the atmosphere and water environment, and at the same time damages the health of the constructors. The use of spray guns or spraying equipment that meet the HVLP standard can reduce flying fog and rebound (overspray), reduce paint, photocatalyst and other solvent emissions, greatly save spraying consumption, while maintaining a clean working environment, protecting the atmosphere and construction personnel Healthy body.

Now, due to the strong economy and environmental protection of spray coating equipment, in foreign countries, most of the spray paint, sanitary ware renovation, photocatalyst construction, etc., use HVLP spray equipment, which can not only obtain excellent surface effects, but also save a lot of money The amount of paint used reduces the unit cost of construction by about 50%. It is particularly worth mentioning that a large number of construction experiments have shown that the use of portable HVLP turbo spraying equipment and a professional HVLP metal spray gun with a diameter of 0.4mm can achieve good results without sagging, uniform coating, and construction efficiency. Higher.

When we select spray coating equipment, we must choose suitable equipment according to the characteristics of the construction at the beginning. If the construction site needs to be changed frequently during the construction process, and the spraying task is not long-term fixed-point construction, we should choose the portable turbine HVLP spraying equipment. For example, spraying photocatalyst, decorating spray paint, woodworking, furniture and sanitary ware renovation, etc.; if you need to fix the spraying task at the construction site for a long time, you should choose a factory-style spray gun, such as an automobile manufacturer, a furniture manufacturer, and so on.

The second is to determine whether the spraying task is for regular construction use or occasional use at home. In foreign countries, equipment is usually distinguished between professional (Professional) and family (DIY). The materials, core components, design and manufacturing standards used by the two are very different, and the use effect and lifespan are also very different. Some importers take advantage of the blind belief and ignorance of imported equipment by domestic users to recommend low-priced family-level equipment to professional users, resulting in frequent maintenance, high maintenance costs, rapid reduction in construction effects, and premature scrapping. .
