Product Description
The molten metal is reacted with an iron matrix to produce an alloy layer, thereby combining the substrate and the plating layer.Hot-dip galvanizing is to pickle the steel pipe first, in order to remove the iron oxide on the surface of the steel pipe, after pickling, it is washed by ammonium chloride or zinc chloride aqueous solution or a mixed aqueous solution of ammonium chloride and zinc chloride, and then fed. Hot dip plating tank. Hot-dip galvanizing has the advantages of uniform plating, strong adhesion and long service life. Most of the northern processes use galvanized strips to directly coil the zinc.
Hot dip galvanizing process:
Workpiece degreasing → washing → pickling → washing → drying solvent dip fluxing preheated hot dip galvanized → cooling →finishing → rinsing → drying → passivation test
Workpiece degreasing → washing → pickling → washing → drying solvent dip fluxing preheated hot dip galvanized → cooling →finishing → rinsing → drying → passivation test
Advantages of galvanized pipes are following below:
Second , after being galvanized pipe galvanized its impact resistance and anti-wear properties are very good, because the zinc coating hardness values larger than the hardness of steel, and therefore the impact resistance of hot-dip galvanized after and abrasion resistance is quite good. Furthermore galvanized biggest advantage is in the corner of the zinc layer will be relatively thick and good toughness and abrasion resistance, while other coatings are often in this corner of the thinnest most difficult construction, and therefore are vulnerable injury.
Third , there is a major feature of hot-dip galvanizing that is occasionally subject to considerable mechanical damage or other causes a small portion of the zinc layer off, the iron-based nudity, then it will play around the zinc layer and other coatings not the same spirit of sacrifice to protect the steel here, so from erosion.
Finally , the hot-dip galvanizing and other aspects of life and aesthetics of art, life expectancy is in a particular environment, the main agency of the thickness of the coating, and the coating thickness of it but also by the thickness of the galvanized pipe and decisions, and therefore thicker galvanized pipe is more easily coating. Second, in terms of aesthetics and art, at the time it is certain severe corrosive environments, galvanized layer above Zaishi paint to deal with, as long as the selection of the correct paint system, easy construction of its anti-corrosion effect will be very good.
