- The optional height of this type of wire mesh is 1 meter, 1.2 meters, 1.5 meters, 1.8 meters, 2 meters. The latter three are the most commonly used, too low to achieve the fence protection effect. The mesh size is divided into 3 cm and 6 cm, and the vast majority of 6 cm is used.
After the corrosion of impregnated hexagonal wire mesh, the original characteristics will be lost, and the shape, color and mechanical properties will be changed, resulting in equipment damage, pipeline leakage, etc., specifically, it is easy to break and lose the original protection function. Usually, there are three kinds of metal corrosion: physical corrosion, chemical corrosion, electrochemical corrosion, corrosion in addition to the chemical properties and organizational structure of the metal itself, but also related to the surrounding medium, such as wet environment is easier to rust than dry environment, more impurities than impurities less easy corrosion, high temperature conditions than low temperature conditions easy corrosion. After understanding these, we can effectively prevent the corrosion of impregnated six-sided wire mesh, prolong the service life of the product.
- The key and important parts with tensile strength greater than 1034Mpa should be relieved of stress at 200±10℃ for more than 1 hour before plating, and the carburized or surface hardened parts should be relieved of stress at 140±10℃ for more than 5 hours. The cleaning agent used for cleaning shall have no effect on the binding force of the coating and no corrosion on the substrate. Acid activation Acid activation solution should be able to remove corrosion products and oxide film (skin) on the surface of parts without excessive corrosion on the matrix.
- Attention should be paid to line collection and operation. Others shall not get on the train without the monitor’s consent. The wire reel should be put lightly, stacked firmly and neatly, not more than 5 discs. It is forbidden to contact human skin directly with acid and base. When the acid fog exceeds the specified target of the state, timely measures should be taken to control it; otherwise, production is not allowed.
Galvanized iron wire is widely used in construction, handicrafts, wire mesh, highway guardrail, product packaging and daily civilian and other fields.
The height of the shield should not be less than two meters. The length of the shield should be the width of the journey and the extension 10 meters away. The vertical load of the handrail on the bridge is 1.2KM/m, and the horizontal external load is 2.5KM/m, both of which should be calculated separately. Galvanized hook mesh belongs to a hook mesh, it is the selection of galvanized wire, hot-dip galvanized wire as raw materials, woven through the hook mesh truncated.
- Post-plating treatment of hot-dip galvanized wire for enhanced protection function, decoration and other special purposes (passivation, hot melting, closing and hydrogen removal, etc.). After galvanized, chromate passivation or other conversion treatment is generally required, forming the corresponding type of conversion film is one of the key processes to ensure the quality of plating. Because hot-dip galvanized wire has a long anti-corrosion life, a wide range of applications, hot-dip galvanized wire to net, rope, wire and other ways are widely used in heavy industry, light industry, agriculture, widely used in the manufacture of wire mesh, highway guardrail and construction engineering and other fields.
The welding core is the metal core of the electrode. In order to ensure the quality of the weld, there are strict regulations on the content of various metal elements in the weld core. In particular, there are strict restrictions on harmful impurities (such as sulfur and phosphorus), and the quality of the weld core metal should be better than that of the base metal. Arc welding cannot be carried out on a smooth rod without a coating. This is because the arc stability is very poor, splashing is very large, and the weld is not well formed. After long-term practice, it is gradually found that the performance of the electrode is greatly improved by coating the welding core with some mineral raw materials (i.e. electrode coating). (1) Ensure stable arc combustion, so that the welding process is normal. (2) Using the gas produced after the drug skin reaction, protect the arc and the molten pool, prevent the harmful gases in the air (such as nitrogen, oxygen, etc.) from invading the molten pool, such as these gases will cause cracks and pores in the welding material, so that the welding can not achieve the ideal effect. (3) After the drug skin is melted, slag is formed, which covers the weld surface to protect the weld metal, make the weld metal slowly cool, help the gas escape, prevent the generation of pores, and improve the structure and performance of the weld. (4) After melting, various metallurgical reactions will be carried out, such as deoxygenation, sulfur removal, phosphorus removal, etc., so as to improve weld quality and reduce alloying element burning loss.

Product features: strong structure, flat surface, with good corrosion resistance, oxidation resistance. The material of small hexagonal mesh is the same as that of other hexagonal mesh, which is generally made of low carbon steel wire, stainless steel wire and galvanized steel wire as raw materials by the hexagonal mesh machine.
Post time: 14-07-22Broken wire is the iron bright wire, fire wire, galvanized wire, plastic coated wire, paint wire and other metal wire, wire factory according to customer requirements for straightening after sizing cut, has the characteristics of easy transportation, easy to use, widely used in the construction industry, handicrafts, daily civilian and other fields. No limit on length, packing as required. Annealing wire also known as black oiled wire, black annealing wire, fire wire, black iron wire. Compared with cold drawing, black annealed wire is more economical as raw material for nails.
- Carbon steel wire is basically do not participate in alloying elements of high carbon steel wire, but also in the low cost of steel wire, hot and cold processing is outstanding, the use of a wide range of steel. Spring steel wire contains high carbon steel wire, high carbon steel wire is the spring steel wire in between.

Building grid (floor heating) has good thermal conductivity and heat dissipation, the appearance of heat dissipation effect is more average 2 cm, 2.5 cm, 5 cm, 10 cm, 15 cm, 20 cm. Wire rope thickness, net length, net width, mesh and other indicators can be stopped at any time according to customer request. The mesh surface, solder joint and mesh are all equal.
- For example, in gray iron, its carbon exists in iron ore in graphite condition, the crack is often gray, soft and strong, simple filtering, suitable for casting. In white iron, its carbon and iron together into iron carbide, crack appears white, very strong and brittle quality, for the material of malleable steel. The alloy grade consists of various alloying elements with different compositions and structures.
- Hexagonal hulanwang custom applications in the channel slope protection work plays a very important role, according to the network performance, it can make is not firmly grasp soil erosion, so hexagonal hulanwang custom slope protection effect is very significant, but also because of this advantage, is widely used in such as channel protection, river bank protection, protection of landslides.
Post time: 26-05-22The tensile strength of cold drawn spring steel wire is slightly higher than that of oil tempered steel wire. The large specification of cold drawn steel wire elastic force is too large, winding the spring is very difficult, so the cold drawn spring steel wire application specification is generally less than 8.0mm, oil quenching tempered steel wire application specification is generally less than 13.0mm. In fact, the diameter of 13.0mm spring is used to light tension spring steel wire, cold drawing wound made into shape and then quenched and tempered. Steel wire with diameter above 15.0mm is mostly made by heating winding process.
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.
- The composition of hot dip galvanizing layer is composed of hot dip galvanizing layer, which is composed of iron zinc alloy between iron matrix and surface pure zinc layer. The shape of the workpiece is formed by the iron zinc alloy layer in hot dip, so that the iron and pure zinc layer touch outstanding. When the iron workpiece is immersed in a molten zinc solution, the initial zinc and iron (body) are formed at the interface. This is a crystal made up of zinc atoms in the solid metal iron. When two metal atoms are fused together, the gravitational force between the atoms is very small.
The production of large rolls of galvanized wire iron can be divided into two categories, is directly from the iron ore after iron stroke exercise out of the metal, the composition of the ore is iron oxide, silica and other miscellaneous stone.
- Packaging: Welding mesh is generally packed with moisture-proof paper (color is mostly gray, yellow, plus trademarks, certificates, etc.), some like 0.3-0.6mm domestic sales of small wire diameter welding mesh, because the wire is relatively soft, coupled with small rolls, customers often require baling and bagging treatment, to prevent damage caused by shipment, etc. The wire of the electric welding net is straight, and also with wavy bend (also known as Dutch net). According to the shape of the mesh surface can be divided into: electric welding mesh and electric welding mesh roll.
The material of steel structure will affect the organization and thickness of hot dip galvanized film. For example, high tension steel containing silicon, carbon content is high, easy to react with molten zinc quickly, the result of excessive growth of alloying, will cause a grayish black appearance, but does not affect its corrosion resistance. Or heat treated steel, if its tensile strength exceeds 90kg/mm2, after hot dip operation, easy to reduce its strength, etc.
- The management system of the rinsing water after the steel wire pickling should be regularly and regularly discharged after the rinsing water, and the rinsing water should be kept clean and low acid value as far as possible. The pH control is more appropriate. The concentration of plating aid should not be too high. Hot plating wire must be added ammonium chloride and zinc chloride according to the data of laboratory analysis, and the specific gravity of the composite solution is controlled in the range of 50~80g/L. The addition of ammonium chloride or zinc chloride raw materials without the results of laboratory analysis shall be subject to criticism and education, and economic treatment if necessary.
