Surface treatment technology for hot-dip galvanized iron wire!
In order to locally remove the surface layer, surface inclusions and the like from the surface of the deposited layer, the defects can be found and treated by conventional techniques; the excess foam is formed by the surfactant and the saponifiable fatty surfactant in the bath. .
Moderate foam formation rates may be harmless. The large denier micro-homogeneous particles present in the bath stabilize the foam layer, but the accumulation of too much solid particles can cause an explosion. Use activated carbon to remove surface active substances. Or the foam is not stable by filtration, which is an effective measure; other measures should be taken to minimize the amount of surfactant introduced.
The introduction of organic matter can significantly reduce the plating speed. Although the chemical formulation is advantageous for high deposition speeds, the thickness of the coating cannot be satisfied after the organic matter is taken, so that the activated carbon can be used to treat the bath.
Zinc is a silver-white metal that is brittle at room temperature, soluble in acid and soluble in alkali, and is called an amphoteric metal. Pure zinc is more stable in dry air. In humid air or water containing carbon dioxide and oxygen, a thin layer of basic zinc carbonate is formed on the surface, which can delay the corrosion rate of the zinc layer.we are provide galvanized iron wire and galvanized wire,you can know it.
The corrosion resistance of the galvanized layer in aqueous solutions of acid, alkali and sodium chloride is relatively low; it is also resistant to corrosion in the atmosphere containing carbon dioxide and hydrogen sulfide and in the maritime atmosphere; in high temperature and high humidity air and in organic acids. The atmosphere is small and the galvanized layer is easily corroded.
The fire wire produced by our factory is very widely used. Because the annealed wire has good elasticity and flexibility, it can control its hardness and hardness during the annealing process. It is made of high quality iron wire and is mainly used for binding wire and binding wire in the construction industry. .
The silk number is mainly 5#-38# (filament 0.17-4.5mm) is softer than ordinary black iron wire, more flexible, uniform softness and uniform color.
