目前,空调通风风管的材料以薄钢板为主,常用的有两种:一种是普通薄钢板;另一种是镀锌薄钢板。一般空调风管制成后,内外表面均刷防锈底漆及面层油漆。从设计到施工,这两种不同性质薄钢板的防腐刷漆做法相同。从理论上分析,这里存在着一定的不合理性。油漆材料是一种涂料,将它涂刷在金属或其它物体表面上,待干结成膜后,能将物体表面与外界空 At present, the material of air-conditioning ventilation ducts is mainly made of thin steel plates. There are two types commonly used: one is ordinary thin steel plates; the other is galvanized thin steel plates. After the general air-conditioning duct is made, the inner and outer surfaces are brushed with rust-proof primer and surface paint. From design to construction, these two different properties of steel sheet are the same for anti-corrosion painting. From the theoretical analysis, there is some irrationality here. The paint material is a kind of paint. It is painted on the surface of metal or other objects. After the film is dried, the surface of the object and the outside world can be empty.
