In addition, heavy hexagonal net is commonly used in water conservancy projects, as the use of loading stone box, in order to achieve the purpose of river management, floods, in addition to it can also be used as slope prevention, retaining wall, breeding and cherish animals. Small hexagonal net is usually used for animal breeding, wall protection network, green vegetation network and so on.
Both sides of the galvanized welding net exposed can not be more than 2mm, so as to be qualified. And in the welding mesh of each warp and weft wire cross place, must be welded very firm, and if you want to welding very firm, both sides must have some warp and weft wire out, and the length must be controlled within two millimeters. From the mesh distribution is not uniform, galvanized is not uniform, but also to see whether the welding mesh is qualified standards. Powder coating color is divided into: blade thorn rope blue, grass green, dark green, yellow. Spray blade gill net is made of hot-dip galvanized steel plate or stainless steel sheet stamped out of sharp knife sheet, high tension galvanized steel wire or stainless steel wire as core wire combination of blocking devices. Because the shape of the thorn rope is not easy to contact, so it can reach excellent protective barrier effect. The primary raw materials of products are galvanized sheet, stainless steel plate, high quality low carbon steel wire (electric galvanized, hot galvanized, coated plastic, plastic spray) wire, blue, green, yellow and other colors.
According to the different requirements of the industry, in accordance with the standard allocation in the smelting furnace, put the different weight of alloy ingots, such as weaving, Ming, paper, lang, silicon, etc., this kind of smelting out of the data is called gold ore iron. Iron has gray iron, white iron and the above-mentioned gold, they have different characteristics, so in the industry according to their different characteristics to transport and selection.
Galvanized wire coating rough, passivation film is not bright, bath temperature is too high. If the cathode current density is too high, zinc content in the bath is too high or sodium hydroxide and DPE content is too low; Solid particles or excessive foreign metal impurities in the electroplating solution can cause such problems. Solution: If the coating of large galvanized wire is rough, there may be solid particles in the plating solution. If the roughness of the part is severe, the current density may be too high.
Wire flexibility and elongation is good, can withstand the pressure of mechanical operation, in our country’s industry has played a very important role. There are many kinds of iron wire, the most common is to give black iron wire, galvanized iron wire. The corrosion resistance of the outer coating is effectively improved, but the phenomenon of crevice corrosion will be found after long-term use.
When the large roll galvanized wire galvanizing process coating foaming, first check the bath temperature. If the bath temperature is not low, then strengthen the plating before removing oil, prevent the matrix metal in acid corrosion. If you pay attention to these problems, the foaming phenomenon still exists, it should pay attention to the amount and quality of additives, then you can stop adding additives, with high current electrolysis for a period of time, in order to reduce the content of additives, observe whether the foaming phenomenon is improved. If there is still no improvement, it is necessary to check whether the storage period of additives is too long, or whether there are too many impurities in the additives.
