Hot dip galvanizing, also known as hot dip zinc and hot dip galvanizing, is an effective way of metal corrosion prevention, mainly used in various industries of metal structure facilities. It is to immerse the steel parts after rust removal into the molten zinc liquid at about 500℃, so that the surface of the steel member is attached with zinc layer, so as to play the purpose of anticorrosion.
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.
Post time: 26-10-22- 6. If the damage volume of the bird cage is large, it needs to be repaired patiently. If the project is large, it needs to be repaired immediately to prevent the damage from continuing to expand. Of course, you can go to the repair shop to maintain specially.
- 2. Dissolution treatment: Put the pickling steel wire into the dissolution tank, and dissolve the zinc powder with the bath liquid by heating, and the dissolved zinc liquid will adhere to the surface of the steel wire.
- There are two kinds of electrochemical protection. One is to connect a piece of metal that is slightly more vivid than it. For example, ships and ships will be inlaid with zinc blocks. The second is to connect the negative terminal of the power supply, such as iron and steel river locks are often connected with the negative terminal of the power supply, through the negative terminal. Its methods include: metal cover film such as electroplating, organic coating such as paint, transformation layer such as orchid or black, new elements to change the metal structure.
With the increasing use of hook mesh, the method of bridge rail is also different. The height of the outer railing of the walkway or seat belt should not be lower than 1.10 meters. The net distance between railings should not be greater than 140 mm and horizontal bar rails should not be used. The planning of the hook mesh is necessary to be safe and reliable, the bolt should be installed on the basis of the railing, its strength should meet the requirements of the standard.
- Although to be able to reduce the production cost, but the strength of the whole product will have a great lack of, so in this case will also let it have a great strength decline. Of course, in the shopping mall, the higher the intensity of the data in production, the higher the implementation of standards, naturally there will be certain progress in price.
The characteristics of galvanized hexagonal net: easy to use; Save transportation costs. It can be shrunk into small rolls and involved in moisture-proof paper packaging, taking up little space. Coating thickness uniformity, stronger corrosion resistance; The construction is simple and does not require special technology; Strong resistance to natural damage and corrosion resistance and adverse weather effects; Can withstand a large range of deformation, and still not collapse. It has the function of fixed heat preservation and insulation.
Hot dip galvanized wire is dipped in zinc liquid melted by heating, with fast production speed and thick but uneven coating. The market allows a low thickness of 45 microns and a high of more than 300 microns. The color is dark, the consumption of zinc metal is much, and the matrix metal forms the infiltration layer, the corrosion resistance is good, the outdoor environment of hot dip galvanized wire can be maintained for decades.
- Post-plating treatment of hot-dip galvanized wire for enhanced protection function, decoration and other special purposes (passivation, hot melting, closing and hydrogen removal, etc.). After galvanized, chromate passivation or other conversion treatment is generally required, forming the corresponding type of conversion film is one of the key processes to ensure the quality of plating. Because hot-dip galvanized wire has a long anti-corrosion life, a wide range of applications, hot-dip galvanized wire to net, rope, wire and other ways are widely used in heavy industry, light industry, agriculture, widely used in the manufacture of wire mesh, highway guardrail and construction engineering and other fields.
1. The surface of the stainless steel pet cage is deposited with dust or alien metal particles containing other metal elements. In the humid air, the condensed water between the attachment and stainless steel will connect the two into a micro cell, which causes the electrochemical reaction and the protective film is destroyed, which is called electrochemical corrosion. To avoid this situation, as long as the stainless steel surface is clean, you can ensure that the stainless steel pet cage does not rust.
- 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: 20-07-22B. When the thickness of the plating is greater than 4 mm, the zinc adhesion should not be less than 610g/m, that is, the average thickness of the zinc layer should not be less than 86 microns.
Stainless steel blade barbed rope under normal circumstances, basically 20 or 30 years is no problem, but because of the problem of its own material will appear a certain degree of rust, this is also because usually stainless steel blade barbed rope used by the material is 304 material, in daily use if in a long-term humid environment will cause certain corrosion. But usually users buy stainless steel blade barbed rope is basically life will not have problems users can also rest assured to use.
Post time: 17-06-24- “At present, many international well-known pet manufacturers have also seized the huge business opportunities of the pet economy, and they continue to develop high-tech pet products, which are favored by consumers.” China’s pet industry should constantly introduce new varieties, strengthen research and development of pet food and supplies, and improve the content of science and technology to win a place in the market competition, an industry insider said.
The external environment has great influence on the preservation of galvanized wire mesh. In the rainy season, it is necessary to pay attention to the air humidity of the workshop, warehouse and other departments. It is recommended to use a humidifier. Usually, the moisture absorption of book paper is larger than that of powder paper, and the pH value is higher. Generally speaking, in the normal environment of storage wire, storage time of two years is not corroded wire phenomenon. However, it should be noted that in the process of handling the iron wire, it should be handled gently to avoid the position of the coiling coil, which will cause the smooth pulling of the wire and affect the production.
- In the field of anti-theft, railway blade barbed rope is favored by people for its economic and practical, good resistance effect, convenient construction and other advantages, and railway blade barbed rope can also be sprayed into various colors, for their own yards and parks and other places to add a lot of luster. Many occasions require a barbed rope.
- 2.25*2.25mm indicates that the two strands are 2.25mm silk, and the thorn thread is also 2.25mm silk;
- C, coating uniformity: galvanized layer is basically uniform with copper sulfate solution test etched five times without exposing iron.
Galvanized hexagonal net uses: building wall fixing, heat preservation, heat insulation; Power plant piping, boiler insulation; Anti-freezing, residential protection, landscaping protection; Raise chickens and ducks, isolate chicken and duck houses, protect poultry; Protect and support seawalls, hillsides, roads, Bridges and other water and wood works.
- Hexagonal net Uses: Used for raising chickens, ducks, geese, rabbits and zoo fences, construction industry wall batching net, daub wall net. Road green belt protection net.
After annealing, iron wire will become softer and more flexible. Iron is a more active metal, and more active than hydrogen, so it is a good reducing agent. At room temperature, iron is not easy to react with oxygen, sulfur, chlorine and other non-metallic elements in dry air, its production cost is low, the use and scale is relatively wide, better protective function, so it is an important material for steel parts used in strict working environment.
- Other discarded guardrails can be used as enclosures for cattle, sheep or other domestic animals. It has a good protective effect. Together these robust products do not have a variety of effects on the overall perimeter. It also shows the value of the rich guardrail network in the community, rural cultivation, or cultivation. Although the appearance of barbed wire fence is not safe after abandonment, the protective function will not be affected, so it will not affect the recovery and use.
