云南快乐10分计算公式 www.pxlrrk.com.cn Tianjin galvanized square tube is divided into hot-dip galvanized square tube and cold-galvanized square tube from the production process. It is precisely because of the different processing of these two galvanized square tubes that they have many different physical and chemical properties. In general they have many differences in strength, toughness and mechanical properties.
The galvanized square tube is such that the molten metal reacts with the iron matrix to produce an alloy layer, thereby combining the substrate and the plating layer. Tianjin galvanized square tube is first pickled by the square tube. In order to remove the iron oxide on the surface of the square tube, after pickling, it is cleaned by mixing the aqueous solution tank of ammonium chloride and zinc chloride, and then sent to the hot-dip galvanizing tank. Galvanized.
