- Reverse twist: Twist the barbed wire in the opposite direction from where the nematocyst is wound around the main wire. It’s not twisted in one direction. It’s called the reverse twist.
Post time: 05-05-23- After the wire mesh appears black spots, you can choose the appearance of treatment to deal with this problem, such as galvanized, paint, dip plastic to deal with, after the appearance of the welding mesh surface smooth and bright, beautiful and generous.
- The use of bundled galvanized wire with the development of industry and agriculture also expanded accordingly. Therefore, galvanized wire products in the industry, such as chemical equipment, oil processing, Marine exploration, transport, electricity, shipbuilding, metal structure, etc.), agriculture (such as sprinkler irrigation, dim room, building (such as water and gas transport, wire casing, scaffolding, house, etc.), Bridges, shipping, etc., has been widely use in recent years. Because galvanized wire goods have beautiful surface, good corrosion resistance and other characteristics, its use scale is more and more extensive.
The quality of hot-dip galvanized barbed wire is only good in the surface of the wire attached to the galvanized layer, and with the chemical reaction, the surface of the zinc layer will gradually lose effect because of the oxidation reaction, this situation is more prominent in the humid area of the environment. And because after all, it is rusty iron wire, so the quality of hot-dip galvanized barbed rope is certainly not up to the level of stainless steel barbed rope.
Because the large volume of galvanized wire alloy elements in iron ore, can make the copper through the material thickening degree of strengthening, hardness, impact force, strength resistance, closing rate, elongation, so alloy iron in the exercise of good iron, is an important supplementary element. The difference between galvanized wire and general iron wire is very big, general iron wire is cheap, and because iron is not very stable, easy to rust in wet places, so the stability is not very good, life is not very long.
Spring wire shall have high tensile strength, elastic limit, endurance and fatigue strength, and be resistant to shock and oscillation. The objectives of strength and endurance, especially the prevention of alteration cracks, are key to the consumption of spring steel wires. The inner and outer quality of wire rod directly affect the function of steel wire.
- Blade barbed WIRE technology: Blade gill net is made of hot-dip galvanized steel plate or stainless steel sheet stamping sharp knife flake, high tension galvanized steel wire or stainless steel wire as the core wire combination of blocking equipment. Because of the unique shape of the gill net is not easy to touch, it can achieve excellent protection and isolation effect. The main material of the products are galvanized sheet and stainless steel plate.
Poor pretreatment before plating; Bath temperature is too low; Poor quality of additives or too many additives and organic impurities will cause poor bonding. The quality of additives also has an effect on coating foaming. Some additives react incompletely during synthesis and continue to polymerize during long-term storage or use. The additive tends to distort the crystal lattice and cause stress, causing the coating to bubble.
- (2) can be used as breeding net, sheep net, cattle net, chicken and duck, isolation chicken and duck house, play the role of poultry protection;
With other coatings, the opposite is true. Rust builds up immediately and spreads quickly underneath the coating, causing it to peel. The depletion of zinc in the atmosphere is very slow, about 1/17 to 1/18 of the corrosion rate of steel, and is predictable. Its life span far exceeds that of any other coating. The life of the coating depends on the thickness of the coating in a particular environment. And the coating thickness is determined by the thickness of the steel, that is, the thicker the steel is easy to get thicker coating, so the thick steel part of the same steel structure must also get thicker coating, in order to ensure a longer life.
- 2. The cage must be strong
- Galvanized iron wire is divided into hot galvanized wire and cold galvanized wire (electric galvanized wire) is made of low carbon steel, after drawing molding, pickling rust removal, high temperature annealing, hot galvanized, cooling and other processes. Galvanized iron wire has good toughness and elasticity, zinc content can reach 300 grams/square meter. It has the characteristics of thick galvanized layer and strong corrosion resistance. The products are widely used in construction, handicrafts, wire mesh, galvanized hook mesh, spackle mesh, highway fence, product packaging and daily civilian and other fields.
- Twine: Twist two or more wires into a double wire rope and then wrap the twine around the double wire. It’s called a straight twist cord which is the common double strand cord.
- The application of electric welding network is more and more widely, and the technology is gradually mature, electroplating rust prevention, plastic processing, used for breeding, grille, coupled with the framework made of guardrail network.
When galvanized wire is galvanized, it is generally necessary to pay attention to the following problems: the duration of the protective effect of galvanized wire is greatly related to the thickness of the coating. Generally speaking, in the dry main gas and in indoor use, the thickness of galvanized wire galvanized layer only 6-12 μm “, and in harsh environmental conditions, galvanized wire galvanized layer thickness needs 20μm “to B height up to 50μm”. Therefore, the environmental impact should be considered when choosing the thickness of galvanized layer. Galvanized wire in galvanized, pay attention to the above problems, can be well galvanized, to ensure the quality of galvanized wire.
Crevice corrosion is a kind of corrosion in small area, especially in concealed position, which can form vicious corrosion cycle. Almost all the crevice corrosion can occur in a metal alloy, with gas containing active anionic neutral medium Z is easy to cause crevice corrosion, crevice corrosion often occurs in the aperture of 0.025 to 0.1 mm, because of long time gathered, the cracks will exist a series of impurities, coupled with the external environment of damp easily corrode the area of the gap is small.
Post time: 18-04-23Galvanized hexagonal mesh weaving process: double stranded hexagonal mesh, can be divided into three screws and five screws.
Aquaculture galvanized welding net this mesh structure is easy to construction, to ensure quality. Compared with the traditional manual binding on site, it can guarantee the quality of the project, shorten the anti-drug construction and shorten the construction period. So now such grids are being used in new villages to strengthen walls and prevent earthquakes.
