Galvanized diamond mesh is divided into hot-dip galvanizing and cold galvanizing. Where is the difference between cold galvanizing and hot dip galvanizing?
Galvanized steel network is the most common product in the diamond mesh products, but if subdivided, there will be a cold galvanizing, hot galvanizing, and there is a big gap in the price and cost. The common name of cold galvanizing is also called galvanizing. It is the use of electrolytic equipment to remove wire or steel wire or wire through oil removal and acid washing in a solution of zinc salt, and connect the negative electrode of the electrolytic equipment. The zinc plate is placed on the opposite side of the wire. The cathode is connected to the cathode of the electrolytic equipment and the directional movement of the cathode from the cathode to the negative electrode will be used. A layer of zinc is deposited on the pipe, and the cold plated tube is machined and galvanized. In this way, the antirust effect of the diamond mesh is common, and its service life is short, because it is cheap, so the dosage is very large.
Cold galvanizing production process:
Chemical degreasing, hot water washing, water washing, electrolysis degreasing, hot water washing, water washing, strong corrosion, water washing, Electrogalvanized iron alloy, water washing, water washing, out of light, passivation, water washing and drying.
Hot dip galvanizing (galvanizing) is also called hot dip galvanizing and hot-dip galvanizing: it is the most effective metal anticorrosion method at present, mainly used in the metal structure of various industries. The steel after rust removal is immersed in molten zinc at about 500 degrees, so that the surface of the steel member is attached to the zinc layer, thereby playing the role of anticorrosion. Hot dip galvanizing process: finished product Pickling - water washing - adding bath - drying - hanging plating - cooling - Medicine - Cleaning - grinding - hot galvanizing, hot galvanizing rope has good antirust effect and long service life, generally it is high speed engineering, prairie fence project, and the first choice of railway engineering.
Hot galvanizing production process:
Feeding, acid pickling, water washing, solvent drying, hot galvanizing, internal and external blowing, rolling marking, marking, passivation, inspection and packaging.
The two materials of the raw materials used in galvanized steel network, or the processing mode of anticorrosion treatment, are directly related to the service life after the installation of the diamond mesh, and the service life of the material is different because of the different zinc content on the raw material. The service life of the hot-dip galvanizing network is more than 3-5 years longer than that of the cold galvanized steel network. At the same time, there is a relatively large difference in the appearance of the diamond mesh. It is easier to distinguish it from the appearance. The hot galvanizing is just bright when it is just produced, but it will react with the air for a period of time and the color will gradually come into being. It's a little dark, but it's not rusty.
