The corrosion or discoloration of galvanized iron wire in the atmosphere caused by oxygen, moisture and other pollution impurities is called rust or rust. After galvanized iron wire rusting, it will affect the appearance quality, seriously affect the use, and even cause scrap, so galvanized iron wire must be properly kept and pay attention to rust prevention.
1. The diameter of raw materials and the thickness of the diameter have a direct impact;
Stainless steel wire is characterized by good corrosion, in chemical plants or pharmaceutical industry can often be used to stainless steel wire, suitable for acid, alkali environment. Aluminum alloy wire is characterized by high temperature, can adhere to the high temperature of more than 100 degrees Celsius does not fade, and has good corrosion, patience is also very good. It can be used for device manufacturing in construction industry.
Low and medium carbon steel wire is used as raw material, with good surface gloss, uniform zinc layer, strong adhesion, corrosion resistance and so on. Available: diameter 1.60mm-4mm (16#-33#) cold plating wire; Diameter 6.40mm-0.81mm(8#-21#) black iron wire, changed wire. It is mainly used in communication equipment, medical equipment, weaving net, brush, steel cable, filter, high-pressure pipe, construction, crafts and other industries.
Paint on the galvanized layer, the binding force between each other and the baking temperature of the paint has a great relationship, after galvanized coating alkyd paint, adhesion is no problem. Galvanized amino paint, paint adhesion is not good. Do two bottom two surface, adhesion is ok, if the two bottom two surface to two bottom three surface, that is, more paint, more baking once, again test adhesion is very poor, poor to the paint from the galvanized layer of pieces torn off.
U-nail price related products: flood control wire mesh: stone cage mesh, gabion mesh, wall mesh, wire cage, honeycomb grid, ecological grid, ecological cage, road reinforcement net, green grid, heavy hexagonal net. Traffic safety protection with wire fence: highway fence network, road fence network, airport fence network, railway fence network, bridge fence network, factory fence, stadium fence, workshop warehouse fence, construction site fence, district fence network. U nail price is a kind of use of high quality Q195 low carbon steel wire row welding, and then cold plating (electroplating), hot plating, PVC plastic bag surface passivation, plasticizing treatment, smooth surface, uniform mesh, welding spot firm, local machining performance is good, stable, anticorrosive, anticorrosive good mesh screen products. Galvanized (electroplating or hot plating) after welding mesh forming; The product is made of high quality galvanized iron wire by precise automatic mechanical welding. It has the characteristics of solid welding spot, reasonable structure, uniform mesh, smooth mesh, solid structure, strong integrity, and strong corrosion resistance. It can also be used for special mesh of floor heating in construction industry.The large hexagonal mesh is called the stone cage net. Stone cage net before delivery, must be folded into a simple surface, packed compressed after delivery. Then put it in the right position to open, and then the block diameter suitable stone into the cage, the cover is tight, and then the various stone cage net and the adjacent stone cage net tied up.
In order to pack and bundle galvanized wire on the surface of the deposit layer to remove the surface film, surface inclusion and other defects can be found and treated by conventional technology; Excess foam is caused by soaps and saponable fatty surfactants being brought into the tank. Moderate foam formation rates may be harmless. Small homogeneous particles of large denier present in the tank can stabilize the foam layer. To remove surface active substances by matting with activated carbon. Or filtration to make the foam less stable, which are effective measures; Other measures should also be taken to reduce the intake of surfactant. The electroplating speed can be significantly reduced by the introduction of organic matter. Although the chemical formula is conducive to a high deposition rate, the coating thickness cannot meet the requirements after the organic matter is loaded, so activated carbon can be used to treat the tank.
From the spraying, spraying blade gill net (PVC blade gill net, coated blade gill net) is also called spraying blade barbed rope, spraying blade barbed wire is produced in the future, to carry out anti-rust treatment attack. Plastic-sprayed surface treatment makes it has quite good anticorrosion ability, beautiful appearance gloss, waterproof effect, convenient construction, economic and practical excellent characteristics. Plastic spraying blade barbed wire is a kind of surface treatment method to spray plastic powder on the product blade barbed wire.Galvanized wire in acid, alkali, sodium chloride aqueous solution of poor corrosion resistance, in the atmosphere containing carbon dioxide and hydrogen sulfide, as well as Marine atmosphere is not corrosion resistance. In high temperature and high humidity air and containing organic acid atmosphere is small, galvanized layer is also easy to be corroded. Galvanized wire and general wire is very different, general wire is cheap, and because the iron is not very stable, easy to rust in the wet place, so the stability is not very good, the life is not very long.
Now many hardware manufacturers produce iron wire, and iron wire is very easy to rust, if you need to use in outdoor or humid places, generally customers will require the use of galvanized iron wire equipment to give the wire a layer of zinc, the thickness can be determined according to user requirements. Galvanized iron wire equipment is specially used for the plating of iron. Generally speaking, the stability of zinc is much higher than that of iron, and it will not rust in the daily water vapor or damp place.
Most cattle nets are mechanically woven from high ductility and corrosion resistance of low carbon steel wire or PVC clad steel wire. Several common materials used in the manufacture of cattle nets are electrogalvanized wire, hot-dip galvanized wire, Galfan plated steel wire, 10 percent aluminum zinc alloy steel wire and the new selenium chromium plated steel wire.And the role of wire mesh in the exterior wall plastering if from an Angle to sail a method of anti-falling, the role of anti-cracking is relatively small, because of the problem of orientation; And about the external insulation system is used in the tile veneer, as for the role should also be anti-drop followed by anti-cracking, so the grid should be selected 10×10×0.6, these are some experience selection, grid conversion from the national provisions of the wire mesh standard, choose the level of steel conversion.
