高压无气喷涂是相对于低压有气喷涂而言的。一般常见的喷涂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”。高压无气喷涂是把涂料直接增至8～40MPa的高压,并迫使涂料通过无气喷枪,经
High pressure airless spraying is relative to low pressure air spraying. Commonly used spray method is the use of compressed air in the gun nozzle to form a negative pressure to the paint flow out and dispersed into droplets coated on the object surface, so compressed air along with the paint flow, 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.” High-pressure airless spray coating is directly increased to 8 ~ 40MPa high pressure, and forced the paint through the airless spray gun, the
