Know briefly about hot dip galvanizing process

In today's industry, steel materials are more widely used, and these materials are used in different environments, which are subject to varying degrees of corrosion. According to statistics, corrosion results in the loss of one third of the total steel and iron materials in the world every year. To ensure the normal use of these products, extend their life, use hot dip galvanizing process, these materials to add a protective film.

What is hot galvanizing? It is the reaction of molten metal and iron matrix to produce an alloy layer, and the matrix and plating are combined. To be galvanized processing, have to put the steel parts for pickling, in order to remove iron oxide on the surface of the steel parts, after pickling, by ammonium chloride or zinc chloride or ammonium chloride and zinc chloride mixed aqueous solution cleaning, in hot dip plating tank, finally is available from the outside world oxidation factors interfere with iron and steel products, even in different environments, can slow oxidation, extended a long use life. Hot dip galvanizing process is to solve the problem of iron and steel metal corrosion.

What is the process of hot dip galvanizing? Need to go up makings, undertake product exterior face cleans namely, cannot have oily dirt also cannot have bump and bump. After loading the material to pickling, use hydrochloric acid pickling, check whether the surface of the product smooth whether there is residual dirt. Through solvent treatment, the solvent tank into all immersion, after the treatment of ammonium chloride and drying, the temperature between 80-180, do not overheat. Then we dip the product into the new field and finish the hot dip galvanizing process. After that, internal and external blowing, marking, passivation, inspection, packaging, etc., this is the complete hot dip galvanizing process, then the product can be successfully galvanized.
