Abstract

The invention discloses an air negative ion detector. The air negative ion detector comprises a metal casing, wherein the metal casing is coated with a film. The film coating process comprises the following steps of (1) sequentially adding 1 to 2 parts of tetrafluoroethylene-hexafluoropropylene copolymer by weight, 1.8 parts of sodium metasilicate by weight, 2.0 parts of inositol hexaphosphate byweight, and 1.9 parts of sodium dodecyl benzene sulfonate by weight into 50 parts of deionized water by weight, and uniformly stirring; (2) sequentially adding 17.5 parts of bromodiethy carbonate by weight, 10.4 parts of 4-Vinyl-1,3-dioxolan-2-one by weight, 2.0 parts of dodecyl dimethyl betaine by weight, and 0.9 part of benzotriazole by weight, continuing to stir, and fully and uniformly mixing,so as to obtain a film coating treatment liquid; (3) placing the metal casing into the film coating treatment liquid to impregnate, fetching out, and drying. The air negative ion detector has the advantages that the surface of the metal casing is coated with a protection film, the property is good, and the surface finish is high.
