Greenhouse building structure with tube
1, hot-dip galvanized steel pipe structure: hot dip galvanized pipe is the molten metal and the reaction of the iron matrix alloy layer, so that both the substrate and coating combination. Hot galvanized pipe is the first pickling pipe, in order to remove the iron oxide on the surface of the steel pipe, after pickling, ammonium chloride or zinc chloride solution or aqueous solution of ammonium chloride and zinc chloride tank cleaning, and then sent Into hot dipping tank. Hot dip galvanized coating with uniform, strong adhesion, long life and other advantages. Hot galvanized steel substrate and the molten bath complex physical and chemical reactions, the formation of corrosion-resistant zinc-iron alloy layer closely. Alloy layer and pure zinc layer, steel substrate integration. Therefore, its strong corrosion resistance.
2, galvanized pipe structure: galvanized pipe to produce the production of hot-dip galvanized pipe made adjustments. In order to remove the iron oxide on the surface of the steel strip, the steel strip is first pickled, cleaned with an aqueous solution of ammonium chloride or zinc chloride or a mixed solution of ammonium chloride and zinc chloride, and then cleaned Into hot dipping tank. Then air-dried, and then made of pipe. With a coating uniform, bright, very little galvanized, than the cost of producing hot-dip galvanized pipe. Its corrosion resistance slightly worse than the hot-dip galvanized pipe!
3, hot-dip galvanized steel pipe and galvanized pipe difference: hot-dip galvanized pipe:
1) color hot galvanized pipe a little whitish, weight: 6.5 kilograms long 6 meters (corrosion resistance, long life, the price is slightly higher);
2) Galvanized pipe snow white, but not shiny, non-reflective, many snowflake-like surface, two ports of zinc tumor (condensed zinc)
Galvanized pipe:
1) Color Galvanized pipe is a little blue, 2) Weight: 5.5 kg in 6 meters long (corrosion resistance is slightly worse than the service life of hot-dip galvanized steel pipe short life, low price economy).
2) Galvanized tube White too bright and reflective, very few snow-like, two-port clean zinc-free tumor.
