Metal surface treatment agent

Metal surface treatment agents are mainly used in machinery (automobiles, passenger cars, tractors, forklifts, mining machinery, etc.), chemical industry, electrician, light industry (washing machines, bicycles, refrigerators, freezers, building materials, steel doors, steel windows, steel pipes, Degreasing, rust removal, chemical products, etc. of small and medium-sized steel parts such as wire drawing). The steel plate is a flat steel that is cast with molten steel and pressed after cooling; the galvanized steel plate is to prevent the surface of the steel plate from being corroded and prolong its service life, the surface of the steel plate is coated with a layer of Chemicalbook metal zinc, this zinc-coated thin steel plate It is called galvanized sheet; aluminum alloy is a general term for aluminum-based alloys. The main alloying elements are copper, silicon, magnesium, zinc, and manganese, and the secondary alloying elements are nickel, iron, titanium, chromium, lithium, etc. Low, but relatively high strength, close to or exceeding high-quality steel, good plasticity, can be processed into various profiles, with excellent electrical conductivity, thermal conductivity and corrosion resistance, the above three are used in aviation, aerospace, automobiles, machinery manufacturing, ships. And the chemical industry has been widely used.
