高压无气喷涂是相对于低压有气喷涂而言的。一般常见的喷漆法是利用压缩空气在喷枪喷嘴外形成负压将漆流带出并分散成雾滴状涂覆在物面上,因而有压缩空气随漆流一起喷出,而常用的压缩空气又是0.4～0.6MPa的低压,涂料在喷出前处于低压状态,因此,这种喷涂方法称为“空气喷涂”。 High pressure airless spraying is relative to low pressure air spraying. Commonly used spray paint is the use of compressed air in the gun nozzle to form a negative pressure to paint flow out and dispersed into droplets coated on the object surface, which has compressed air along with the spray out, and the commonly used compressed air Also low pressure of 0.4 ~ 0.6MPa, the paint is in a low pressure state before ejection, therefore, this spraying method is called “air spraying.”
