The character of galvanization silk reachs skill demand

Galvanization silk divides again for galvanizing silk and cold galvanization silk (electric galvanization silk) difference is:

Galvanizing is to heating plating of the dip inside the zincic fluid of melt, produce rate is rapid, film is deep but inhomogenous, the lowermost ply that bazaar promises 45 micron, highest can amount to 300 micron above. Colour is darker, expend zincic metal much, form with base metal enter a layer, be able to bear or endure corrode sex is good, the galvanizing below the environment outdoor can hold to a few years.

Cold galvanization (electric galvanization) it is to be in eletroplate through electric current one-way sex makes zinc progressively inside groove surface of the metal on plating, produce rate is slow, film is even, ply is thinner, want 3-15 micron only normally, the exterior is shining, corrosion resistance is poor, normally a few months are met rustily.

Relative to galvanizing, electric galvanization produces cost is inferior.

Cold galvanization and galvanizing difference:

Cold galvanization and galvanizing difference are to go up namely zincic amount is different, can identify from colour they, cold galvanization colour shines hair silvery white contains yellow. Galvanizing shines hoar color.

Galvanizing uses scale:

Because the film of earning is deeper, galvanizing relatively electric galvanization has better defend function, because this is,make with the iron and steel at strict work environment important safeguard film. Galvanizing finished product is in structure of treatment of chemical equipment, oil, marine exploration, metal, electric power is carried, the profession such as shipbuilding has wide application, water is like to reach like pesticide sprinkling irrigation, greenhouse and bldg. in agricultural category gas carry, electrical wiring bushing, scaffold, bridge, highway protects the respect such as column, in recent years already abundantly is chosen.
