Abstract

The invention discloses an electromagnetic valve surface environment-friendly treatment process. The process comprises the following steps: A, firstly, carrying out sand blasting treatment on the surface of an aluminum product to remove surface oxides; B, carrying out primary washing on the aluminum product subjected to sand blasting, and naturally drying at normal temperature; C, putting the dried aluminum product into an electrolyte for anodic electrolysis, and generating a protective film; D, carrying out secondary water washing on the aluminum product subjected to anode electrolysis, and putting the aluminum product into a low-temperature drying oven for drying; and E, finally, spraying a layer of antioxidant on the surface of the dried aluminum product to finish the treatment of the surface of the aluminum product. The electromagnetic valve surface environment-friendly treatment process adopted by the invention is environment-friendly, non-toxic and high in treatment efficiency, the aluminum product can be effectively treated, and the oxidation phenomenon of the aluminum product after long-time use is prevented.

Description

technical field [0001] The invention relates to the technical field of surface treatment of aluminum products, in particular to an environmentally friendly treatment process for the surface of an electromagnetic valve. Background technique [0002] Aluminum products are a general term for daily necessities and industrial products processed from aluminum alloy as the main raw material. Aluminum alloy is a general term for alloys based on aluminum. The main alloying elements are copper, silicon, magnesium, zinc, manganese, and the secondary alloying elements are nickel, iron, titanium, chromium, lithium, etc.; the aluminum alloy has low density, but relatively high strength, which is close to or exceeds high-quality steel, and has good plasticity and can be processed Formed into various profiles, it has excellent electrical conductivity, thermal conductivity and corrosion resistance. It is widely used in industry, and its usage is second only to steel. [0003] The surface o...
