Post time: 15-08-22- Pure zinc is more stable in dry air. In moist air or water containing carbon dioxide and oxygen, the surface will generate a layer of basic zinc carbonate based thin film layer, which can delay the corrosion rate of zinc layer. Comparison of corrosion resistance of zinc coating in aqueous solution of acid, alkali and sodium chloride; It is also resistant to corrosion in atmospheres containing carbon dioxide and hydrogen sulfide and in oceanic atmospheres; In high temperature and high humidity air and contain organic acid atmosphere is small, galvanized layer is also easy to be corroded.
- This material itself has the advantages of good integrity, uniform force, high strength, wear resistance, corrosion resistance and so on. Moreover, the production process is simple and the degree of industrialization is high, so its economic benefits are better than other metal mesh materials. In some industrially developed countries, this material has long been used in urban and rural roads, tarmac runway is also widely used. The application of galvanized wire welding net in the construction industry is countless, and the application of galvanized wire welding net in the construction industry has been greatly developed.
With the improvement of people’s living standards, many families are raising some small pets, which also need a stable nest. Pet carrier has become a more important item in people’s choice, and each pet’s different habits and living habits will choose the cage suitable for it.
There is no adhesion test of powder spraying or fluorocarbon spraying on packaged galvanized wire, but there are two points for reference: first, in sealed or air-free environment, non-metallic volatiles can corrode zinc coating; Second, zinc at higher than 230 degrees (c) will cause the matrix metal brittle. And powder spraying and fluorocarbon spraying are to be baked at a higher temperature and in a sealed environment, causing rapid corrosion of zinc, resulting in loose corrosion film resulting in coating adhesion decline, and even lead to (matrix) steel wire brittle situation may exist.
The management system of the rinsing water after the steel wire pickling should be regularly and regularly discharged after the rinsing water, and the rinsing water should be kept clean and low acid value as far as possible. The pH control is more appropriate. The concentration of plating aid should not be too high. Hot plating wire must be added ammonium chloride and zinc chloride according to the data of laboratory analysis, and the specific gravity of the composite solution is controlled in the range of 50~80g/L. The addition of ammonium chloride or zinc chloride raw materials without the results of laboratory analysis shall be subject to criticism and education, and economic treatment if necessary.
For the specification of galvanized wire, the galvanized wire produced by our factory can range from No.8 to No.22, which refers to the BWG standard, that is, from about 4mm to 0.7mm, which can basically cover the type required by customers. As for the raw material of galvanized wire, normally, we use Q195 mild steel, and some factories will also use SAE1006 or SAE1008. The following is the zinc coating, for galvanized wire, this thing is more important, the general zinc coating is about 50g/m2 to 80g/m2, some customers need high zinc galvanized wire, zinc coating can reach 200g/m2 to 360g/m2. The tensile strength of galvanized wire is usually 350n/m2 to 800n/m2. Then there is the packaging specification of galvanized wire. The specifications of small rolls of galvanized wire are 50kg/ roll, 100kg/ roll and 200kg/ roll. Of course, there are large rolls of galvanized silk, the weight can reach 300kg/ roll or 800kg/ roll.
Post time: 28-11-221. Grid structure is simple, beautiful and practical; 2. Easy to transport, installation is not limited by terrain relief; 3. Especially for mountain, slope, multi-curved area adaptability; 4. Medium low price, suitable for large area use. Main market: railway, highway closed net, yard fence, residential guardrail, all kinds of isolation net.
Galvanized wire coating rough, passivation film is not bright, bath temperature is too high. If the cathode current density is too high, zinc content in the bath is too high or sodium hydroxide and DPE content is too low; Electroplating solution with solid particles or excessive foreign metal impurities, will lead to such problems. Solution: If the large roll galvanized wire to the above coating is rough, there may be solid particles in the plating solution. If the roughness of the part is severe, the current density may be too high.
Railway is not only the main artery of national economy, but also an important means of mass transportation to protect people’s travel. It plays an important role in the process of economic and social development. Therefore, the safety issue is an important guarantee for railway transportation, one is a symbol of the railway transportation enterprise product quality, the other is also the focus of social attention. The off-road collision accident is one of the focus of public opinion on the railway industry. How to grasp the off-road safety management, eliminate the off-road collision accident from the source, maximize the protection of people’s life and property safety, and reduce the non-operational cost of railway enterprises is a key content of railway safety work in the new era. We should install protective nets on both sides of the railway, which are also barbed wire protective nets, so as to prevent accidents.
Post time: 18-10-22Hot dip galvanized iron wire using high quality carbon structural steel, after drawing, galvanized iron wire processing. Hot dip galvanized iron wire is widely used in wire mesh, highway guardrail and construction projects. It has the characteristics of thick coating, strong corrosion resistance and strong coating. And according to the special needs of users, according to industry standards to provide various specifications of galvanized wire.
Post time: 15-11-22- Steel mesh benefits: Compared with traditional handmade steel mesh, steel mesh has better elasticity and even spacing. When pouring concrete, the steel mesh is not easy to bend, and the thickness of concrete protective layer is easy to control and even. In bridge deck surfacing, measure the protective layer of steel mesh. The pass rate is 95 percent.
- Of course, these are limited to the maintenance of the indoor balcony, so outdoor, some of this is less than maintenance, some maintenance will waste resources, because of the expected life, in order to ensure the safety of the role, timely update is good.
- Material: low carbon steel wire, stainless steel wire, PVC wire, copper wire
- The reason for the bridge reinforcement is that the bridge durability function is poor and aging, through the steel wire mesh reinforcement, can prolong the service life of the bridge, to avoid the bridge cracks, collapse and other phenomena, steel wire mesh in the bridge reinforcement anti-crack engineering can play an obvious effect, improve the construction speed of the project, enhance the concrete anti-crack function, sum up the economic benefits.

There are many categories of large rolls of galvanized wire, and different categories can be applied to different scenarios. The common application of galvanized iron wire is the application of the construction industry. One is the use of binding wire. Whether it is the binding of scaffolding or reinforcement, galvanized iron wire is needed to carry out. There are also 20kg or 50kg bundles of No. 18, No. 16, No. 14, No. 12, No. 10 galvanized coils.
