Widely used in practice, iron wire also has certain harm, simple rust and corrosion, so we can generally use galvanized method to prevent product corrosion. Together in addition to this method, metal commonly used treatment methods and phosphating treatment, oxidation treatment, etc. Metal phosphating treatment: iron and steel products to remove oil, rust, into the specific composition of the salt solution soak, you can form a layer of water soluble salt film on the surface of the metal, this process is called phosphating treatment.
On the contrary, the denser the ion deposition, the better the quality of zinc layer. Under the condition that the surface zinc layer is dense and bright, the quality of zinc layer per unit area should reach 80g/m2, and the process parameters should be optimized as follows: current density is 16-20A /dm2, mass concentration of zinc sulfate solution is 500g/L, and pH value is 2.5-3.0.
1. Used for mountain farming, road isolation, large farming enclosure protection, it is recommended that you choose 3mm wire diameter products.
2, performance characteristics. Zinc coating is thick, fine crystallization, uniform and no pores, good corrosion resistance; Is pure, the zinc plating layer in acid, alkali corrosion slower, such as fog Eng effectively protect tight sand-fixation matrix, the galvanized layer formed after chromate passivation, color white, army green, beautiful and easy, have certain adornment sex, because the galvanized layer has good ductility, and therefore can be rushed, rolling, cold bending and forming and not damage the coating.
When we buy barbed rope, we need to know the kilogram weight of each bundle and the length to be used, so as to decide which product to buy. Or let it check directly into how much money a meter, is also a means to avoid being cheated. What you need to know when buying is the weight, and the length of the barbed rope can be customized from 50-250 meters. If the barbed rope is installed in a large area, it is recommended to use the barbed rope of 250 meters to reduce the use cost and logistics and transportation costs.
Post time: 18-07-22Pet cats are animals that people keep to relieve loneliness or for entertainment purposes. A pet cat is one of the more perfect animals: good-looking, independent, not dependent on its owner, giving more but taking less. The cat’s sensory organs are extremely well developed and always respond to its surroundings with keen sensitivity. Cats are very docile and have a rich body language to express their emotions. They purr when they are happy and pet you with their front PAWS. Some cats have a special habit of jumping on your lap to impress you. If a cat squats and gently wags its tail from side to side, it is an invitation to play. A twitch of the tail means it is angry.
- And the role of wire mesh in the exterior wall plastering if from an Angle to sail a method of anti-falling, the role of anti-cracking is relatively small, because of the problem of orientation; And about the external insulation system is used in the tile veneer, as for the role should also be anti falling followed by anti-cracking, so the grid should be selected 10×10×0.6, these are some experience selection, grid conversion from the national provisions of the wire mesh standard, choose the level of steel content conversion.
In the process of composite electroplating galvanized wire, the plating solution must be stirred to obtain the composite coating in which the particles dispersed in the matrix metal. Stirring methods include mechanical stirring, air stirring, ultrasonic stirring, bath circulation, etc. The acid activation solution in the production process can remove the corrosion products and oxide film on the surface of the low carbon steel wire without excessive corrosion on the matrix.

- Great attention should be paid to pickling of large rolls of galvanized wire. Acid is highly corrosive. Therefore, when adding acid, the acid must be poured into the water, and it is along the wall of the cylinder, and not thrown down at once, so as not to cause splashing. Remember the order of acid pouring, acid into water rather than water into acid, water into acid will cause splashing and boiling, when pouring acid must wear protective glasses, beside must ensure that there are no non-professional people watching, so as not to cause some acid splashing danger.
- 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.
- Because the coating obtained is thicker, hot-dip galvanizing has very good protective function than electric galvanizing, so it is an important maintenance coating for iron and steel parts in strict working environment. Hot-dip galvanized products are widely used in chemical equipment, petroleum processing, Marine exploration, metal structure, electric power transportation, shipbuilding and other occupations. In the field of agriculture, such as pesticide irrigation, greenhouse and construction industry such as water and gas transportation, wire casing, scaffolding, Bridges, highway guardrail and other aspects, it has been widely used in these years.
The surface coating of galvanized wire can be seen 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. High quality galvanized wire in general, the zinc layer attached to the surface of the wire is relatively thick, so when we buy galvanized wire, as long as we look at the thickness of the zinc layer, we can generally judge the quality of galvanized wire.
Reduce the impact of the project on the environment, protect the slope protection area of land, maintain the rock can be fully strong, slope protection hook flower net through artificial planting grass planting, the implementation of green function. Suitable for any complex terrain, at the same time, does not destroy the original landform, the product is mesh distribution, visual interference, convenient for artificial afforestation, conducive to the environment, engineering and environment integration system flexibility.
Post time: 31-08-22In the purchase of barbed rope should be customer demand, so the amount of galvanized is different, then the two kinds of barbed rope and what is the difference, some customers need high zinc blade barbed rope, but high zinc blade barbed rope price to ordinary galvanized barbed rope price is more than 1000 yuan per ton, the two kinds of barbed rope products, the former is used in many aspects, such as the military, the government’s barbed rope, The latter is more for civilian use.
- Galvanized also has several different methods, the so-called hot dip galvanizing is put racing in the zinc bath, need to clean them on metal, which ensures that formed between metal and coating adhesive, after cleaning, the matrix metal is dissolved, to clear any residual oxides of residue and then immerse the substrate metal heating liquid zinc, and metallurgical bonding is formed.
Post time: 01-11-22Galvanized electric welding mesh refers to the mesh made of zinc alloy material, because of its high strength, high hardness, beautiful appearance, bright color and other advantages, become used in residential communities. Traditional electric welding mesh using iron bars, aluminum alloy materials, need to use welding and other technology, and the texture is soft, easy to rust, single color.
① The diameter of galvanized iron wire for drawing shall not be less than 4mm, and the diameter of galvanized iron wire for binding shall not be less than 2.6mm.
The hot plating wire is made of low carbon steel wire rod, which is processed by drawing forming, pickling and rust removal, high temperature annealing, hot dip galvanizing and cooling. Galvanized iron wire has resistance and elasticity, the amount of zinc can reach 300 g/square meter, with thick galvanized layer, strong corrosion resistance and other characteristics. Widely used in construction, handicrafts, wire mesh, highway guardrail, commodity packaging and ordinary civilian and other fields.
- Although galvanized hook mesh is outstanding because of its surface, this does not mean that this hook mesh product is not useful. From the point of view of people’s use of it, this hook mesh products through a surface of galvanized treatment, whether it is wind and sun, or man-made inadvertent damage, will not bring a little harm to it, so the more comprehensive use of galvanized hook mesh products will then be widely used in several fields.
