The whole welding process of galvanized steel wire mesh does not need special technological methods, good weldability. However, in a few cases, the welding process will present difficulties: the converter steel produced by the old smelting method has high nitrogen content and high impurity content, resulting in high cold brittleness, added aging sensitivity, lower quality of welded joints, and poor weldability.
When the large roll galvanized wire galvanizing process coating foaming, first check the bath temperature. If the bath temperature is not low, then strengthen the plating before removing oil, prevent the matrix metal in acid corrosion. If you pay attention to these problems, the foaming phenomenon still exists, it should pay attention to the amount and quality of additives, then you can stop adding additives, with high current electrolysis for a period of time, in order to reduce the content of additives, observe whether the foaming phenomenon is improved. If there is still no improvement, it is necessary to check whether the storage period of additives is too long, or whether there are too many impurities in the additives.
- Galvanizing refers to the surface treatment technology of plating a layer of zinc on the surface of metal, alloy or other materials to play the role of aesthetics and rust prevention. The main method used now is hot galvanizing. However, hot dip galvanizing industry has been developed with the rapid development of cold strip rolling in the past 30 years. The production process of hot-galvanized sheet mainly includes: raw plate preparation → pre-plating treatment → hot-dip plating → post-plating treatment → finished product inspection and so on.
- 5. Environmental conditions: Galvanized wire in different environmental conditions, its corrosion resistance may also be different. For example, in acidic environment, zinc layer is easy to be corroded; The corrosion resistance of zinc layer is better in alkaline and neutral environment.
Cold galvanized, generally speaking, do not need heating, galvanized amount is little, this galvanized parts are easy to fall off in wet environment. Hot dip galvanizing, also known as hot dip galvanizing, is to melt the zinc ingot at high temperature, put some auxiliary materials in, and then dip the metal structural parts into the galvanized groove, so that the metal members are attached to a layer of zinc layer. The advantage of hot dip galvanized is that its anticorrosion ability is strong, the adhesion and hardness of galvanized layer is better.
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.
Different from the general zinc barbed rope, the zinc content of the surface of the high zinc barbed rope is very high, which can reach 6-8 times of the former, so that it has a great advantage in service life. Ordinary products begin to corrosion in three or five years, while the latter takes longer time to change.
High-speed road guardrail net, hexagonal mesh of all kinds of guardrail net, the value of the high-speed road is more prominent, it is not only used in a variety of roads, in a variety of sports ball fields and landslides to take care of, but also to reach a very close utility.
When the ground is undulating, the installation method of barbed rope also needs to be changed accordingly, because the installation of the original installation method will not play a protective effect.
One is to do a good job of galvanized wire packaging, avoid bump, to ensure the integrity of the zinc layer;
- Some birds suffer from illness due to poor diet or other injuries, and need timely treatment so that the birds can recover.
- In addition to these reasons, we should also pay attention to the tooling and process must be stable, and regular testing should be done to ensure the uniformity of galvanized layer.
- 4, galvanized can be used zincate galvanized or chloride galvanized process, should use appropriate additives to meet the requirements of this standard coating.
- Galvanized wire is divided into hot galvanized wire and cold galvanized wire (electric galvanized wire). Hot dip galvanizing is dipped in zinc liquid melted by heating. It has fast production speed, thick but uneven coating. The market thickness is 45g and can reach more than 300g. The color is dark, the zinc metal is consumed, and the matrix metal is formed into the entry layer, the corrosion resistance is good, and the outdoor environment of hot dip galvanized can adhere to decades.
- 5. The bird cage should be sprayed with transparent wood environmental protection paint every 1-2 years. This protects the cage’s skeleton from the effects of weathering.
- The chromium-plated layer has good thermal property. When the temperature is heated below 500℃, its luster and hardness are not changed obviously. When the temperature is higher than 500℃, the initial oxidation and discoloration occur, and the hardness decreases when the temperature is higher than 700℃. The friction coefficient of chrome coating is small, especially the dry friction coefficient, which is low among all metals. So the chrome coating has good wear.
- For example, if the barbed rope is used for circling, the cost per meter is only a few yuan. If the other products are used for circling, it may be more than ten or even 20 yuan. This is undoubtedly to increase the cost of users again, so the barbed rope is the most economical and affordable product for breeding cattle and sheep.
- Large rolls of galvanized wire products are widely used because of its anti-rust and anti-corrosion effect, because zinc has a great protective effect on the appearance of the product, so it greatly improves the role and characteristics of the product itself, which also promotes the promotion of the application of the product. The characteristics of galvanized wire products on galvanized wire products are the factors that determine many characteristics of galvanized wire products.
Post time: 31-08-22- In the calculation process of 12*14 specifications of barbed rope, it can not be calculated according to the above calculation formula, because first of all, two specifications of raw materials are used, the thinner the wire diameter, the higher the processing cost. Generally speaking, a kilogram of 12*14 barbed rope can reach about 7.5 meters, and the ratio of warp wire to barbed rope cannot be calculated according to the traditional ratio of 7 to 3. The exact amount of stinging and use the warp need to increase after a series of professional measurement on the loss of raw materials and so on factors to calculate.
Post time: 07-02-23Blade thorn rope because the volume is relatively large, so the thorn rope factory is used to packaging.
Post time: 18-04-23Galvanized wire can be used zincate galvanized or chloride galvanized and other processes, appropriate additives should be used to obtain the coating required by the standards of low carbon steel wire. When the galvanized wire out of light plating should be carried out light treatment, the galvanized wire bath to control the temperature. Now the quality level of galvanized wire on the market is not equal, galvanized wire is also called hot dip zinc and hot dip galvanized, is an effective way of metal corrosion prevention, mainly used in various industries of metal structure facilities.
- Packaging is also very important, cut wire to do a good job in the bundle with plastic film tightly packed, and then in the regular box, to fill the whole box is very full and sealed, it is best not to have a half box of conditions, if there is a half box to fill with foam and other things, so that in the transit cut wire will not receive a little damage.
Post time: 18-05-23The construction of inner wall and outer wall steel wire mesh can effectively solve the wall cracks, falling off, empty drum phenomenon. Hot dip galvanized steel wire mesh material requirements: net surface leveling, width and length to meet the project required standards, welding process, weight, zinc, etc., with more production and operation, detection certificate is complete.
Some customers pay more attention to the quality problem, so they pay more attention to the service life. The barbed rope factory will generally recommend the use of high zinc barbed rope or stainless steel barbed rope.
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.
