The silver powder is actually a mixture of aluminum powder and polymer after painting the film, the film is brittle, easy to appear adhesion problems, and corrosion resistance is also slightly poor. Galvanizing refers to the surface of metal, alloy or other materials coated with a layer of zinc to play the role of beautiful, rust prevention and other surface treatment technology. Zinc dissolves easily in acids and also in bases, so it’s an amphoteric metal. Zinc changes little in dry air.
- In addition, when using the steel wire, it is also necessary to pay attention to protecting the surface of the steel wire. For example, if the surface of the steel wire is damaged or corroded, it may affect its electrical conductivity. Therefore, in the use of steel wire, should try to avoid steel wire with wet environment or chemical substances in order to protect its surface and electrical conductivity.
- Most people think that the fine wire of the front and back twist barbed wire is not as thick and durable as common sense, but the front and back twist barbed wire is made of hot-dip galvanized steel wire, which is more than three times greater than the tensile strength of iron wire, and the amount of zinc added is not less than hot-dip wire
- D, coating adhesion; The zinc layer of the plating parts should be firmly combined with the base metal with sufficient adhesion strength, and will not fall off or bulge after the hammer test.
Post time: 23-11-22Advantages: The cost of hot dip galvanized rust prevention is lower than that of other paint coating. In suburban environment, the standard hot-dip galvanized rust prevention thickness can adhere to more than 50 years without repair. In urban or offshore areas, the standard hot-dip galvanized rust protection layer can last 20 years without repair. Galvanized layer and steel is a metallurgical connection, into a part of the steel surface, so the durability of the coating is more reliable.
- 1. Water washing: Clean the galvanized steel wire to remove the residual zinc liquid and impurities on the surface.
- So, do you know how to choose the right dog cage? Choose a dog cage to focus on quality and practicality! Let’s take a look:
- A. When the thickness of the plating is 3-4 mm, the zinc adhesion should be less than 460g/m, that is, the average thickness of the zinc layer is not less than 65 microns.
Stainless steel blade barbed wire production process is similar to galvanized blade barbed wire production process, usually according to the mold to determine the size of the blade.
Stainless steel blade barbed rope material is produced according to stainless steel plate and stainless steel wire, as a whole have achieved the purpose of high quality anticorrosion. So how long can stainless steel blade thorn rope be used?
Post time: 30-03-23- Because the large roll galvanized wire alloy element in ore iron, can make copper through the thickness, hardness, impact force, strength, library rate, elongation, so alloy iron in the exercise of good iron, is an important auxiliary element. Galvanized wire and general wire is very different, general wire is cheap, and because the iron is not very stable, easy to rust in the wet place, so the stability is not very good, the life is not very long.
The use of packaging galvanized wire with the development of industry and agriculture is also expanded accordingly. Therefore, galvanized silk commodities have been widely used in industry (such as chemical equipment, petroleum processing, Marine exploration, metal structure, electric power transportation, shipbuilding, etc.), agriculture (such as irrigation, heating houses), construction (such as water and gas transportation, wire casing, scaffolding, houses, etc.), Bridges, transportation, etc., in recent years. Because galvanized silk products have beautiful surface, good corrosion resistance and other characteristics, its use is more and more extensive.
Cattle fence network in outdoor use for a long time will inevitably appear rusty corrosion, this time the use of cattle fence network life depends on the maintenance of the product is not in place, we all know that cattle fence network if a long time exposed to the harsh environment, the service life will be greatly reduced. How long does a normal cattle net last?
- Some welding methods of galvanized steel mesh will reduce the quality of low carbon steel welded joints, such as electroslag welding. Because the line energy is high, the coarse grains in the heat affected zone of welding will become very coarse, leading to a severe reduction in impact toughness. After welding, it is necessary to normalize with refined grains to improve impact toughness.
No matter how big they are, dogs seem to love touching noses with people and other animals. In fact, nose touching is a form of social interaction for dogs, much like shaking hands and hugging humans. But dogs don’t rub their noses with every person or animal. They choose who to rub their noses with. If they don’t like you or don’t know you at all, they won’t touch your nose. However, adult dogs will touch the nose of almost every puppy. They will not only touch the puppy’s nose, but also smell the puppy.
- And for the external insulation system is used in the brick veneer, as for the role of first should also be anti fall off followed by anti cracking, so should choose the grid 10×10×0.6, these are some experience choice, grid conversion from the national regulations of steel mesh specifications, using steel level conversion. The index of wire mesh size, wire warp, square meter steel content, galvanized amount, etc., mainly consider the corrosion resistance of wire mesh and the safety of the system! Galvanized wire mesh is more critical than wire diameter, galvanized amount is very important, must be hot plating, welding after plating is better than plating after welding, as for wire diameter, comprehensive consideration of site construction and to meet the needs of safety, 0.6 ~ 0.7 is better.
- In white iron, its carbon and iron phase into iron carbide, crack white, extremely strong and brittle, for the malleable steel material. Alloy grades are made up of various alloying elements with different compositions and structures. Because the alloy element in the iron can make the copper material thick strengthening degree, hardness, impact force, strength resistance, collection rate, elongation rate, so the alloy iron in the exercise of high quality iron, is an additive element.
Post time: 17-11-22- Production technology: Through the excellent low carbon steel rod drawing forming, pickling rust removal, high temperature annealing, hot dip galvanizing. Cooling and other 5 operation processes refined. Galvanized wire characteristics: good resistance and elasticity, strong corrosion resistance.
- 5, after the light plating should be carried out light treatment.
Every time galvanized wire production enters the peak season of the industry, the road leading to the factory will see from time to time transport wire and container vehicles, as well as galvanized bright wire short-distance transport trucks, driving the labor utilization rate in the surrounding countryside, solving the employment problem of most people. Galvanized wire is divided into hot dip galvanized wire and cold galvanized wire difference: hot dip galvanized is in the heated melting zinc liquid dip plating, production speed is fast, the coating is thick but not uniform. Dark color, consumption of zinc metal, and matrix metal formation of infiltration layer, good corrosion resistance, hot dip galvanizing in outdoor environment can be maintained for decades.
Large roll galvanized wire phosphating film is dark gray to black gray, the thickness is generally 5-20μm, has better corrosion resistance in the atmosphere. Membrane is a microporous structure, strong adsorption ability to paint, such as used as paint bottom, corrosion resistance can be further advanced. Metal oxidation treatment: Add steel products to NaOH and NaNO2 mixed solution, heating treatment, the surface can form a layer of thickness of about 0.5-1.5μm blue oxide film, in order to reach the purpose of steel corrosion prevention, this process is called blue treatment, referred to as blue.
Post time: 31-10-22Annealed wire is mainly made of soft iron wire through low carbon steel heating, hot drawing, constant temperature and other processes. Because of the differences in use, there are also different in the production process, and the specifications are varied. Annealed wire can be widely used, mainly because annealed wire and other kinds of wire, has many advantages.
Electric galvanized wire direct selling is in the plating tank through the current one-way to gradually zinc plating on the metal appearance, the 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, the production cost of electric galvanizing is lower. 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 galvanizing shiny white.
- 2. Breeding small animals such as chickens, ducks and geese, enclosure protection for fruit trees and gardens, and protection for medium-sized breeding, it is recommended that you choose products with a wire diameter of 2.3mm-2.5mm.
- There are many kinds of zinc plating solution, which can be divided into plating solution and no plating solution according to its properties. The galvanized liquid has good dispersion and covering property, the coating crystal is smooth and fine, the operation is simple, the application range is wide, and the long-term use is in the production. However, due to the toxic substances contained in the plating solution, the gas escaping from the plating process has great harm to the health of workers, and the waste water must be treated strictly before discharge.
- Combination of fence mesh and maintenance network restrictions: Residential fence net, garden villa, private swimming pool, courtyard lawn, city scene, municipal transportation, sports venues, airports and ports, offices and schools, military equipment, prison farms, industrial parks, tourist resorts, distribution centers, The specifications and parameters of the fence mesh are as follows: 800, 1000, 1200, 1400, 1600, 1800, 2000, 2200, 2400 (mm) : 2000, 2500, 3000 mesh spacing (mm).
1: according to the different color of the sprayed blade barbed rope, its price is 2000-2200 yuan higher than the ordinary blade barbed rope, but the cost performance of the sprayed blade barbed rope is much higher.
Large hexagonal mesh called stone cage net, is mainly used for mountain protection, hydraulic construction and so on. Small wire hexagonal mesh is used as a good material for breeding, will twist twist hexagonal mesh in the welded iron frame on the hexagonal mesh welding into chicken coop, pigeon cage, rabbit cage cage cage, hexagonal mesh is the best material for breeding with a net.
