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.
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.Compared with other galvanizing processes, the cleaning requirements for low carbon steel wire before galvanizing are low. However, under the current trend of increasing the quality level of galvanized layer, some pollutants brought into the plating tank are obviously harmful. Because cleaning galvanized coating wastes a lot of time and reduces the production, it is very important to properly clean and effectively rinse the substrate before electroplating.
Therefore, the rust of galvanized black iron wire has a great relationship with storage. At the same time, after rust, it should also be reasonable for post-treatment to avoid affecting its use effect. Of course, when the black iron wire is galvanized, the thickness of the galvanized layer should be ensured, so that the possibility of rust can be reduced. Speaking of galvanized iron wire, perhaps many people think it is relatively rare, in fact, it is not.
Stainless steel blade barbed rope production process is basically similar to galvanized blade barbed rope production process, usually according to the mold to determine the size of the blade.
Iron has gray iron, white iron and the above – mentioned combination of gold, each of which has different characteristics, so in industry, according to their different characteristics to transport and selection. For example, in gray iron, its carbon exists in iron ore as graphite, and the crack is often gray, soft and tough, simple filter cutting, which is suitable for casting.
We basically know that the barbed wire fence generally has two kinds of ring and linear filamentous, the overall protective wire mesh selection of galvanized, stainless steel processing raw materials, long-term use is not easy to rust. Barbed wire fence uses stainless steel barbed wire, plastic coated barbed wire, aluminum coated barbed wire, galvanized barbed wire and other raw materials through special wire drawing into the strand planning, has a strong role in protection and maintenance. Widely used on both sides of the highway, grassland, gardens and other places, because it is a field protection product and therefore updated faster, so how to use the barbed wire fence after abandonment? Here are some of the uses of discarded blades.
2. Preheating: Put the steel wire into the preheating furnace to increase its temperature in order to better react with the molten zinc liquid.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, and small in humid air or water containing carbon dioxide and oxygen. A thin film layer of basic zinc carbonate will be formed on the surface, which can delay the corrosion rate of zinc layer. The corrosion resistance of galvanized layer in aqueous solution of acid, alkali and sodium chloride is relatively strong. It is also not resistant to corrosion in atmospheres containing carbon dioxide and hydrogen sulfide and in Marine atmospheres; In high temperature and high humidity air and containing organic acid atmosphere is small, galvanized layer is also easy to be corroded.
The hoop diameter of 8mm is combined with the cement column guardrail specially customized and equipped with nuts and anti-theft washers. The surface treatment is galvanized, respectively. There are three kinds of bracket hoop at the column cap, bracket hoop at the center column, bracket hoop with encryption bracket, etc. The protective effect of nematocyst rolling cage is good.After proper heat treatment or cold drawing hardening, high carbon steel wire has high strength and hardness, high elastic limit and fatigue limit (especially notched fatigue limit), cutting function is acceptable, but welding function and cold plastic deformation ability is poor.
There is in place to use, the blade thorn rope is commonly border, installation and use of the fence, and prisons, and galvanized barbed wire is in the orchard, fence livestock and so on the installation of large area, although the use of relatively large, but not as good as the use of blade thorn rope and high grade, so this is also the main reason for the price is quite high. Finally, the general installation site of the blade barbed rope for the protection level requirements are relatively high, so the quality requirements for the product is also relatively high, but the ordinary galvanized barbed rope because of the requirements in the installation site is more casual, which is also for the processing process for the quality requirements are relatively low.
Cattle net in outdoor use for a long time will inevitably show rust corrosion, this time the use of cattle net life depends on the maintenance of the product is not in place, we all know cattle net if a long time exposure to the harsh environment, the service life will be greatly reduced. How long does a normal cattle net last?
One is to do a good job of galvanized wire packaging, avoid bump, to ensure the integrity of the zinc layer;
