:How to deal with large volume galvanized wire anticorrosion
How to deal with large rolls of galvanized wire anticorrosion? Large-volume galvanized wire is widely used in practice. It also has certain harmful effects, and it is rust and corrosion. Therefore, galvanizing can be used to prevent product corrosion. In addition to this method, the common treatment methods for metals are phosphating, oxidation treatment, etc. Let us introduce the characteristics of these two methods.we provide galvanized iron wire and electro galvanized wire
,you can know it.
Phosphating treatment of metal: After the oil and steel products are degreased and rusted, they are immersed in a specific composition of the acid salt solution to form a water-insoluble acid salt film on the metal surface. This process is called phosphating. The large-volume galvanized silk phosphating film is dark gray to black gray, and the thickness is generally 5-20 μm, which has good corrosion resistance in the atmosphere. The membrane is a microporous structure and has strong adsorption capacity for paints and the like. For example, as a paint primer layer, corrosion resistance can be further advanced.
Oxidation treatment of metal: The steel product is added to a mixed solution of NaOH and NaNO2, and heat-treated to form a blue oxide film (mainly Fe3O4) having a thickness of about 0.5-1.5 μm to reach the steel. For the purpose of corrosion protection, this process is called blue treatment, referred to as blue. This oxide film has greater elasticity and lubricity and does not affect the accuracy of the part.we provide galvanized iron wire and electro galvanized wire

Therefore, the components of precision instruments and optical instruments, spring steel, thin steel sheets, thin steel wires, etc. are commonly used for blue processing. The commonly used galvanizing treatment is equivalent to forming a protective layer on the surface of the wire. Commonly used methods include hot-dip galvanizing, thermal spraying, vacuum plating, etc. Different methods have corresponding characteristics.
