The price of galvanized iron wire is relatively low, but the corrosion resistance is excellent, so it is favored by many screen businesses. In the production process of galvanized iron wire, first of all, we should check the equipment to see if there are any problems, and then we should look at the galvanized process, whether there are factors that cause product discoloration. If these problems do not exist, or some of them occur on the same equipment, and some are normal, then we should consider the problem of raw materials at this time.
- “Wet” hot dip galvanizing is also called “molten solvent method” hot dip galvanizing. Iron and steel workpiece through degreasing, pickling and cleaning, it is necessary to set in a special box above the surface of the molten zinc in the “molten solvent” (also called cosolvent), and then into the zinc liquid to galvanized. The molten solvent is usually a mixture of ammonium chloride and zinc chloride, but also other chlorine salts.
Post time: 24-03-23- 2: plastic spraying blade barbed rope characteristics of beautiful color, according to the use of the environment to choose the color, so that it and the surrounding environment. Paint color including grass green, dark green, black, red, white and so on.
Large roll galvanized wire is simply galvanized iron wire, usually used wire is often visible, because iron is very easy to be corroded and rusted, so it is necessary to put a layer of other not easy to rust metal plating in the outer layer, to achieve the effect of corrosion resistance and rust resistance, the effect of zinc can do more. Therefore, many customers often require hardware factories to produce galvanized iron wire, which requires the use of galvanized iron wire equipment.
The derusting steel parts are immersed in the melted zinc liquid at about 500℃, so that the surface of the steel member is attached with zinc layer, so as to achieve the purpose of anti-corrosion. The surface of galvanized wire coating can see whether the quality of galvanized wire is good or not. If the strength of zinc attached to the wire is very poor, then this galvanized wire do not buy, because this galvanized wire must be poor galvanized wire.
Take 20cm galvanized wire for acid fog experiment, check the zinc content of galvanized wire through the balance to see whether it meets the zinc layer standard required by customers, ensure that the metal wire achieves the role of rust and corrosion prevention, and meet the service life required by customers. Galvanized iron wires must be packed in good condition, bound neatly and orderly, and bound inward to prevent scratches during transportation. The inspection standard of galvanized iron wire also includes the tensile test, which is decided according to the material of the galvanized wire order ordered by the customer, and it needs to be tested by comparing the raw material list.
The characteristics of hexagonal net: solid structure, flat surface, with good corrosion resistance, oxidation resistance and other characteristics: used for raising chickens, ducks, geese, rabbits and zoo fences, mechanical equipment protection, highway guardrail, sports places Seine, road green belt protection net. The screen in the production of box shaped container, with stone filled with cages, can be used to protect and support seawall, hillside, road and bridge, reservoir and other civil engineering, is a good material for flood control and flood resistance, namely (stone cage net, stone cage cage).
Post time: 13-04-23- In sulfur dioxide, hydrogen sulfide and Marine atmosphere, zinc corrosion resistance is poor, especially in the high temperature and high humidity atmosphere containing organic acid, galvanized wire galvanized layer is easy to be corroded. The surface of galvanized wire galvanized layer uniformity and color of galvanized wire, good quality galvanized wire surface galvanized layer uniformity, zinc adhesion is good, and the color is white, no leakage plating and rust points.
- 2. Zinc layer uniformity: zinc layer uniformity also has an important impact on corrosion resistance. If the zinc layer is not uniform, there are local defects or insufficient thickness areas, it is easy to form corrosion points, resulting in the destruction of the entire zinc layer.
- Pure zinc is more stable in dry air. In moist air or water containing carbon dioxide and oxygen, the surface will generate a layer of basic zinc carbonate based thin film layer, which can delay the corrosion rate of zinc layer. Comparison of corrosion resistance of zinc coating in aqueous solution of acid, alkali and sodium chloride; It is also resistant to corrosion in atmospheres containing carbon dioxide and hydrogen sulfide and in oceanic atmospheres; In high temperature and high humidity air and contain organic acid atmosphere is small, galvanized layer is also easy to be corroded.
Post time: 10-03-23- I’m going to take the middle one. Steel wire galvanized is very important, must master galvanized, galvanized, because there are many methods, but we first must choose hot plate, welding mesh material, and then excitation, and diameter of steel wire is mainly according to the construction requirements, as well as the requirements of the range of application.
- 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. Zinc is a silver-white metal, brittle at room temperature, soluble in acid and alkali, known as amphoteric metal. Pure zinc is more stable in dry air. In humid air or small water containing carbon dioxide and oxygen, the surface of large rolls of galvanized wire will generate a layer of basic zinc carbonate based thin film layer, which can delay the corrosion rate of zinc layer.
Post time: 06-01-23National standards on the use of wire mesh standards have certain requirements, diameter and mesh size matching use, rather than simply diameter, on the plaster layer to use the mesh should not be greater than 20×20, diameter is not easy to be less than 1mm, just choose diameter is not much meaning, choose 40×40×0.9 and choose 10×10×0.6 wire mesh, Which is better? I’m afraid it’s 10 by 10 by 0.6.

Post time: 12-08-22Hot dip galvanizing is a kind of external treatment technology in the production of fasteners. The common varieties of hot dip galvanizing fasteners are electric galvanizing, powder galvanizing, mechanical galvanizing and hot dip galvanizing. Wire factory according to different requirements of customers for fasteners, different hot-dip galvanized surface treatment. Galvanized layer and steel is a metallurgical connection, become a part of the steel surface, so the durability of the coating is more reliable.
- Since nose touching is an important part of dogs’ social behavior, humans can use this to train them. Experts say that if owners touch their dogs’ noses often when they are young, they will grow up to have softer personalities and be far less likely to hurt people.
The lighting surface of each type of shed is designed to be curved, improving the Angle of the light surface, because the lighting surface is curved, no dust accumulation, good light transmittance, high temperature in the shed, after measurement, the average temperature in the shed is 3℃ higher than the traditional bamboo pole cement column shed, the yield is increased by 15~20%, and the harvest date is advanced. The formula is scientific, the surface does not absorb moisture, do not return halogen through modification technology and scientific production process, solve the greenhouse frame rod is easy to absorb moisture return halogen, poor water resistance and easy to change the shortcomings, so that the greenhouse steel pipe in the high temperature and high humidity environment, few drops, frost phenomenon, and reduce pests and diseases.
2. Eliminate the caked zinc residue at the zinc liquid surface
