Corrosion can lead to significant operational issues, including system failures and increased maintenance costs. Corrosion inhibitors, such as phosphates and organic compounds, are used to form protective films on metal surfaces, thereby reducing the rate of corrosion. These chemicals are especially important in cooling water systems and boiler feedwater treatment.

Steel wire and iron wire have many similarities, but carefully distinguish, will find that they are not only different in the material, but also in the product characteristics of the great difference. So when choosing, be sure to make a clear distinction between the two. Steel wire factory introduces steel wire carbon structural steel made above, generally not galvanized, used for machinery, spring. Black, very hard; Wire: made of mild steel (mild steel), galvanized, used for joining and binding. White and soft.

The appearance quality of cold-drawn low carbon steel wire in each inspection lot shall be all visually inspected. The appearance of steel wire shall not have cracks, burrs, corrosion and mechanical damage affecting mechanical function. Cold-drawn low carbon steel wire with unqualified appearance can be used in engineering after treatment and inspection.
- (4) Stop the use of more than two strands of galvanized iron wire around the operation method.
- 3. Scope of application. Electrogalvanizing involves more and more extensive fields, fastener products have been widely used in machinery manufacturing, electronics, precision instruments, chemical industry, transportation, aerospace and so on in the national economy is of great significance.
- Galvanized wire can be seen as iron wrapped in carbon, when extinguished, the surface is comparable to shallow carbon can contact with oxygen, produce carbon dioxide gas, will wrap it in iron (this is a molten state) radiation in. The more carbon there is in the galvanized wire, the more likely it is to spark. The iron-encased carbon is like dynamite in a dynamite bag, blowing the iron away from time to time.

Our country industry chooses the low carbon steel with good quality as raw material, and then produces the quality galvanized iron wire by drawing, galvanizing and other processes. Now the production technology of galvanized iron wire products can be divided into hot plating and electroplating two kinds of methods. No matter which one is chosen, it should be carried out in accordance with the corresponding operating specifications, so as to better ensure the production of good products. For key and important parts with tensile strength greater than 1034mpa before plating, the stress should be released at 200±10℃ for more than 1 hour and 140±10℃ before plating.
- Uses: used in industry, agriculture, animal husbandry, highway, forest protection

Field fence line net is a streamlined, streamlined, beautiful, tacky, fashionable European elegance; The diversity of color selection, a variety of standard color card color choice, can meet different varieties, different needs. The field fence line network can be separated with a variety of methods, and according to the customer’s request.

The production process of large coil galvanized wire is relatively simple. The wire after cleaning is put into electroplating solution first. Of course, the plating solution should contain zinc oxide, a direct current of steel, another zinc plate in the plating solution. The zinc is transferred to the surface of the steel as a molecule. If it shows a bright and beautiful color, the wire is coated with zinc.

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.

The corrosion or discoloration of galvanized iron wire in the atmosphere caused by oxygen, moisture and other pollution impurities is called rust or rust. After galvanized iron wire rusting, it will affect the appearance quality, seriously affect the use, and even cause scrap, so galvanized iron wire must be properly kept and pay attention to rust prevention.
- Generally speaking, it is necessary to install thorn rope in pasture, which is simpler and saves time and effort. It is better managed because it is full of spikes that keep livestock away from the barbed fence.

Galvanized hexagonal net is a kind of galvanized metal wire mesh, mesh shape is hexagonal.
-
Barbed rope factory not only provides the sales of blade barbed rope, including the subsequent construction is also contracted, and the construction price is particularly different.

Plastic paint is often see way of electrostatic daub, can be fixed on the periphery of the barbed wire or iron wire board, requires two baidu after heat treatment, make plastic paint or powder coating adhesive on the wire plate, these are painted plastic razor wire is commonly used in indoor boxes, plastic paint surface look overall feeling is very good, strong adhesive force, at the same time is more durable, Coating processing does not take too long, mainly rust prevention and corrosion effect is quite good, much better than the general material.

For mountainous or hilly areas where the ground is more undulating set up stakes. You need to set a stake at the beginning and the end, and then determine the position. In the middle of the ups and downs, to increase the stakes according to the complexity of the ups and downs of the terrain, we need to be able to see 3 stakes at the same time, so that the installation is. It’s a straight line.
- 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.
