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.
- The strength of the hook mesh should be satisfied: when the vehicle is traveling at 80 kilometers per hour, the hook mesh will not fall into the river when it bumps against the rail at a 15 degree Angle. The shape and color of the hook mesh should be in harmony with the surrounding natural environment. The phenomenon planning of the important Bridges of the hook network should be done well. When the bridge crosses important traffic lines, such as expressways, urban rail transit, expressways, railway trunk lines, etc., the hook mesh should add the protective mesh on the pavement of the bridge deck.
There are many ways to choose the blade stabbing rope, and it is necessary to choose reasonably when choosing. Blade barbed rope is very good in the market reputation, and different types of blade barbed rope can play different roles, so how should we choose blade barbed rope? What are the main points?
The utility of the hexagonal net in the playground is very superficial, in each city to build the playground, are less than the shadow of the hexagonal net. In the stadium around the installation of hexagonal nets, not only can improve the stadium group image, but also convenient city residents to carry out a row of activities.
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 galvanizing is in the hot melt zinc liquid dip plating, production speed, thick but uneven coating, the market allows the thickness of 45 microns, up to 300 microns above. It is dark in color, consumes more zinc metal, forms infiltration layer with base metal, and has good corrosion resistance. Hot dip galvanizing can be maintained for decades in outdoor environment. The protection of zinc coating on iron matrix has two principles: on the one hand, although zinc is more active and easy to oxidize than iron, but its oxide film is not as loose and compact as iron oxide. The dense oxide layer formed on the surface inhibits the further oxidation of zinc in the interior.
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.
If the coating roughness is not caused by the above reasons, it may be caused by impurities in the plating solution. Can take a small amount of electroplating solution, filtration test, and then take a small amount of electroplating solution, with zinc powder treatment after the test, check the problem is solid particles or copper, lead and other foreign metal impurities caused by. One by one, it’s not hard to find the cause of the problem. Galvanized iron wire coating blister, poor adhesion.

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.
This oxide film has greater elasticity and lubricity, does not affect the accuracy of parts. Therefore, the parts of precision instruments and optical instruments, spring steel, thin steel sheet, fine steel wire and so on are commonly bluing treatment. The commonly used galvanizing treatment of large roll galvanized wire is equivalent to forming a protective layer on the surface of the iron wire. The commonly used methods are hot dip galvanizing, hot spray plating, vacuum plating and so on. Different methods have corresponding characteristics.
- Hexagonal cage has a wide range of applications, with the progress of science and technology, has been extended to the major hydraulic engineering, civil engineering. Geotechnical engineering and other projects. In the hydraulic hexagonal cage in the river construction to reach the utility, that is appropriate and the use of hexagonal cage used to fill stone, fixed river, can be used to avoid river erosion bring water and soil loss. In the civil engineering project, the hexagonal cage is considered appropriate and the use of similar particle size volume particle filling, the mesh wall is formed between the cage, which is the stone cage mesh retaining wall.

If the surface of galvanized wire is black and the galvanized layer is thin and uneven, the galvanized wire is partly because the inventory storage time is longer, but also because the production technical requirements of galvanized wire do not meet the standard and lead to the quality problems of galvanized wire. According to the use of galvanized wire is different, galvanized wire has soft and hard, then the galvanized wire used for binding requires the flexibility of galvanized wire is better, the flexibility of galvanized wire is good, and it can be easy for workers to operate.
When the barbed rope is used, it is calculated according to the length, while when purchasing the barbed rope, it is calculated according to the weight of the barbed rope, which causes the confusion of users’ difficulty in counting the quantity of purchase. Therefore, it is necessary to understand clearly that there are less meters per kilogram of the barbed rope. How much does a barbed rope weigh in a meter? These two problems, the purchase of barbed rope becomes very simple.

- Hexagonal mesh is a metal wire woven Angle mesh (hexagonal) made of wire mesh, the use of metal wire diameter is based on the size of the hexagonal and different. If it is a hexagonal metal galvanized layer of metal wire, the wire diameter is 0.3mm to 2.0mm metal wire, if it is a PVC coated metal wire braided hexagonal net, the use of 0.8mm to 2.6mm PVC(metal) wire. Twisted into a hexagonal shape, the outer frame edge of the line can be made into a unilateral, bilateral, movable silk.
- Galvanized hexagonal net is a galvanized metal wire mesh, the shape of the grid is hexagonal.
- ③ The galvanized iron wire shall not be damaged when it is tightened.
- First of all, the protective layer of zinc-iron alloy can prevent the steel wire from being corroded by oxidation. The zinc metal reacts with water and oxygen to form a dense zinc oxide layer, which forms a physical barrier to prevent oxygen and water from entering the inside of the steel wire, reducing the chance of corrosion. Compared with ordinary steel wire, hot-dip galvanized wire is more resistant to corrosion in humid, high humidity or corrosive environments such as acid and alkali, so it is more durable.

Stainless steel blade barbed wire production process is similar to galvanized blade barbed wire production process, usually according to the mold to determine the size of the blade.
When laying steel wire mesh, according to the laying method from the middle to both sides in turn. Wall plastering engineering use wire mesh material is generally two kinds: one is electroplating, the other is hot dip galvanized. The former has low cost and a wide range of use. The cost of hot-dip galvanized material is slightly higher than that of electroplating, and the cost is high and the life is good to prevent rust. Hot dip galvanizing is in the case of heating plating. After the zinc is melted into liquid form, the base metal is immersed in it so that the zinc interpenetrates with the base metal and binds so tightly that there are no other impurities or defects left in the process.
- To stop normalizing or soxhlet processing of wire rod, spheroidization annealing is used instead of large specification. In the middle, especially before the waste drawing process, the thermal disposal of soxhlet is widely used. Prevent decarbonization during thermal disposal. After hot disposal, sulfuric acid or hydrochloric acid pickling is used to remove the iron sheet. Coating can be used to dip lime, phosphating, borax treatment or copper plating.
