- Three is to do a good job of galvanized silk product production site clean and tidy, in accordance with the scientific method of operation to operate the production, the operator should wear the required dress. If it is hot dip galvanized wire products, we must do a good job of passivation treatment, will be able to effectively prevent discoloration, prolong the method of discoloration, can solve the problem of discoloration.
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.
Post time: 02-09-22Galvanized iron wire is widely used in construction, handicrafts, wire mesh, highway guardrail, product packaging and daily civilian and other fields.
- Because the anti-aging and anti-corrosion ability of zinc and aluminum alloy wire is much higher than galvanized barbed rope, it is widely used in a variety of places with few personnel and lack of maintenance ability, and there is the protection of coastal areas.
The antisepsis of these materials is very different, the use of life is not the same. Cold galvanized cattle net, also known as electroplating, galvanized amount is small, rust in rain, but the price is cheap, the service life is 5-6 years. The amount of zinc on hot dip galvanizing (low zinc and high zinc) is about 60g to 400g, the service life is about 20-60 years, and the corrosion resistance is general.
- Galvanized iron wire has excellent endurance and elasticity, zinc can reach 300 grams/square meter. It has the characteristics of thick galvanized layer and strong corrosion resistance. Widely used in construction, handicrafts, wire mesh, highway guardrail, commodity packaging and ordinary civilian and other categories.
- 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.
- Galvanized iron wire has tolerance and elasticity, the amount of zinc can reach 300 g/square meter. It has the characteristics of thick galvanized layer and strong corrosion resistance. Widely used in construction, handicrafts, wire mesh, highway guardrail, commodity packaging and ordinary civilian and other fields.
Post time: 28-02-23Welding mesh is widely used in industry, agriculture, breeding, construction, transportation, mining and other aspects. Such as machine shields, animal fences, flower fences, window fences, access fences, poultry cages, egg baskets and home office food baskets, paper baskets and decorative. We can make it according to the special requirements of customers. Welding mesh is made of high quality low carbon steel wire row welding, and then cold plating (electroplating), hot plating, PVC plastic coated surface passivation, plasticizing treatment, smooth mesh, uniform mesh, solid solder joint, local machining stable performance, corrosion resistance, corrosion resistance. Features: Stainless steel mesh selection of high quality stainless steel wire row welding, more acid, alkali resistance, solid welding, beautiful, widely used and so on.
- First of all, the protective layer of zinc-iron alloy can prevent the steel wire from being corroded by oxidation. The zinc metal reacts with water and oxygen to form a dense zinc oxide layer, which forms a physical barrier to prevent oxygen and water from entering the inside of the steel wire, reducing the chance of corrosion. Compared with ordinary steel wire, hot-dip galvanized wire is more resistant to corrosion in humid, high humidity or corrosive environments such as acid and alkali, so it is more durable.
- In want to use barbed wire fence ground road at both ends of each set up a stake, and then from the two stakes, every 30m to set up a stake, until the installation of the line is full of stakes, so installed barbed wire net is a straight line.
This oxide film has greater elasticity and lubricity, does not affect the accuracy of parts. Therefore, the parts of precision instruments and optical instruments, spring steel, thin steel sheet, fine steel wire and so on are commonly bluing treatment. The commonly used galvanizing treatment of large roll galvanized wire is equivalent to forming a protective layer on the surface of the iron wire. The commonly used methods are hot dip galvanizing, hot spray plating, vacuum plating and so on. Different methods have corresponding characteristics.
- The galvanized requirements of the parts to be plated: the surface of the parts to be plated should be smooth, and there is no dirt that cannot be removed by pickling method. Such as paint, grease, cement, asphalt and excessive rotten harmful substances; All welds of welded components shall be sealed without air; Pipe fittings and containers must have exhaust and zinc inlet holes; The workpiece should be finished welded steel pipe without thread, if any thread should be protected.
- At present, some manufacturers also use the process of sandblasting equipment for wire pretreatment, sandblasting process is carried out in the sandblasting room, but in the process of sandblasting, dust will permeate the whole sandblasting room, produce a lot of dust that is not easy to collect, and if the dust will be discharged at will.
- Many pet carriers are designed with a small box in the base, so that pets can clean up when they poop. At the same time, it is also convenient for pet hygiene. For example, if there is no leakage of excrement in the box, pet excrement will be on the ground, which is quite unsanitary. If you have a box you can easily take it out and clean it out so it doesn’t get all over the place, so it’s more hygienic.
- Hexagonal net weaving methods: positive twist, reverse twist, two-way twisting, first editing after plating, first plating after editing, and then divided into hot dip galvanized hexagonal net, electric galvanized hexagonal net, PVC plastic coated hexagonal net, stainless steel hexagonal net, etc.
In view of this situation, many manufacturers are committed to ensuring the corrosion resistance of titanium and titanium alloy under the premise of increasing the hardness of titanium alloy, and surface carburizing is one of the typical processing technology means. Similar to the surface carburizing treatment of steel, the surface carburizing treatment of titanium alloy is to make the active carbon atoms, diffusion to the internal of titanium alloy, the formation of a certain thickness of higher carbon content of the carburizing layer, after quenching and tempering, so that the surface layer of the workpiece to obtain high carbon content of titanium alloy wire.
Electro galvanizing shaft wire direct is in the electroplating tank through the current unidirectional zinc gradually plated on the metal surface, production speed is slow, uniform coating, thin thickness, usually only 3-15 microns, bright appearance, poor corrosion resistance, generally a few months will rust. Compared with hot dip galvanizing, electric galvanizing has lower production cost. The difference between cold galvanizing and hot galvanizing: the difference between cold galvanizing and hot galvanizing is that the amount of zinc is different. They can be identified from the color. The color of cold galvanizing is shiny silver white with yellow. Hot dip galvanized shiny hair white.
2, the production and installation is simple and fast, the use of patented friction connection or special connection accessories for installation, greatly improve the installation efficiency.
- The most obvious gap in a short time is the cross section. Because the hot-dip galvanized barbed rope is surface anticorrosive treatment, there will be rust in the cross section, while the stainless steel barbed rope because the internal raw materials are consistent with the surface raw materials, so there is no such situation.
In order to pack and bind galvanized wire in the surface of the sedimentary layer to local removal of surface film, surface inclusion and other defects can be found and treated by conventional technology; Excess foam is formed when soap and surfactants such as saponified fats are brought into the tank. Moderate rates of foam formation may be harmless. Small, homogeneous particles of large denier present in the bath can stabilize the foam layer. Use activated carbon mat to remove surface active substance. Or through filtration to make the foam is not too stable, which are effective measures; Other measures should also be taken to reduce the amount of surfactant introduced. The electroplating speed can be obviously reduced by the addition of organic matter. Although chemical formulations facilitate high deposition rates, the deposition of organic matter does not meet the requirements of coating thickness, so activated carbon can be used to treat the bath.
