- Reconnect the negative battery cable. Start the vehicle and test the gear shifter through all gears to ensure it operates smoothly without any binding or sticking.
- The wire mesh is finished by fine welding of active welding equipment. The material can be divided into cold drawing wire, hot dip galvanized, cold galvanized, dip plastic and so on. To be used for bridge reinforcement, deck paving, building reinforcement, etc.
- Take the blade cord for example, the quality of the cord and the shape and direction of the surface barbs are what consumers need to consider.
- In the processing of stainless steel barbed wire after cold galvanized or hot galvanized coating on the surface of the last zinc material, not only beautiful but also plays a good protective role.
- The most obvious gap in a short period of time is the cross section of this piece, hot dip galvanized wire because it is surface anti-corrosion treatment, so in the cross section of this piece will appear rust, and stainless steel wire because the internal raw materials and surface raw materials are consistent, so there is no such situation.
- Suitable for general engineering building wall, pouring concrete, multi-storey building, etc., in the structure of heat preservation and heat insulation system plays an important role, when the construction will be hot dip galvanized welded wire rack together wall of heat preservation and heat insulation board placement will be concrete pouring mold inside, outside the wall heat preservation and heat insulation board and one kind of live, after ripping into heat preservation and heat insulation board and wall body. The coating on the surface of the welding core is called the coating.
Large roll galvanized wire can be divided into hot-dip galvanized wire and cold galvanized wire, the difference between the two lies in the way of zinc and the amount of zinc. Hot dip galvanizing is to soak steel wire in melted zinc liquid, hot dip galvanizing zinc fast, zinc layer thick rust prevention performance is very good, but the zinc is not uniform, and the surface is dark, the life of hot dip galvanizing can reach 20 years.
In the calculation process of 12*14 specifications of barbed rope, it can not be calculated according to the above calculation formula, because first of all, two specifications of raw materials are used, the thinner the wire diameter, the higher the processing cost. Generally speaking, a kilogram of 12*14 barbed rope can reach about 7.5 meters, and the ratio of warp wire to barbed rope cannot be calculated according to the traditional ratio of 7 to 3. The specific use of how much wire and silk need to go through a series of professional measurement but also increase the loss of raw materials and other factors to calculate. Thorn rope factory will also according to customer needs to calculate the reasonable amount of customer use.
- 1, prepare for the bird cage
Large hexagonal net called stone cage net, stone cage net before delivery, must be folded into a simple surface, packed compression after delivery. Then put it into the right position to open, and then put the appropriate size of the stone into the cage, the lid tight, and then the various stone cage net and adjacent stone cage net tied up.
The surface coating of galvanized wire can be seen whether the quality of galvanized wire is good or not. If the strength of zinc attached to the wire is very poor, then this galvanized wire do not buy, because this galvanized wire must be poor galvanized wire. High quality galvanized wire in general, the zinc layer attached to the surface of the wire is relatively thick, so when we buy galvanized wire, as long as we look at the thickness of the zinc layer, we can generally judge the quality of galvanized wire.
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.
- Hard black galvanized iron wire is made of low carbon steel wire by wire drawing machine. Hard black galvanized iron wire is the first feature of high hardness, bright appearance. It is mainly used for welding clothes hanger, umbrella, metal mesh, basket, basket and other metal products. Soft black galvanized iron wire is made of low carbon steel wire after annealing and softening, and then cold drawing. Soft black galvanized iron wire is the first feature of good flexibility, slightly higher hardness, bright appearance. Mainly used for metal mesh weaving technology, welding net, process products of welding.

Post time: 11-11-22The characteristics of this kind of small animal cage, is small, light, easy to carry, but also easy to clean care. For small animal cages, the wire diameter of the general iron wire is not very large, the thickness of the plastic is relatively thin, so the use of the time can not be “violent”, or the cage under the “destruction” will occur welding or plastic crack off.
With the improvement of people’s living standards, now many families are raising some small pets, these small pets also need a safe nest, pet cage has become an important choice of people, each pet’s habits and living habits will choose to adapt to the cage.
- ③ Galvanized iron wire shall not be damaged when it is tightened.
- Especially after passivation of galvanized layer, the surface of the oxide layer is thicker and compact, itself has high oxidation resistance. On the other hand, when the surface of the galvanized layer is damaged, exposing the inner iron matrix, because zinc is more active than iron, zinc will bear the role of sacrificing zinc anode, zinc will be oxidized before iron, so as to protect the iron layer will not be damaged.
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.
Galvanized wire is divided into hot galvanized wire and cold galvanized wire (electric galvanized wire). Hot dip galvanizing is dipped in zinc liquid melted by heating. It has fast production speed, thick but uneven coating. The market thickness is 45g and can reach more than 300g. The color is dark, the zinc metal is consumed, and the matrix metal is formed into the entry layer, the corrosion resistance is good, and the outdoor environment of hot dip galvanized can adhere to decades.
Post time: 15-02-23On the contrary, the denser the ion deposition, the better the quality of zinc layer. Under the condition that the surface zinc layer is dense and bright, the quality of zinc layer per unit area should reach 80g/m2, and the process parameters should be optimized as follows: current density is 16-20A /dm2, mass concentration of zinc sulfate solution is 500g/L, and pH value is 2.5-3.0.
- 2, mesh, mesh also directly affect the price of stone cage net
If the zinc coating is good, but when the light comes out in 3% nitric acid, there is a dark shadow on the coating, and the film is brown when passivation occurs, which may be caused by foreign metal impurities such as copper or lead in the galvanized liquid. When there is a problem in the process of galvanizing, check the temperature and current density first, and then measure and adjust the content of zinc and sodium hydroxide in the bath through the analysis of the bath. Whether DPE levels are low can be determined by Hull cell test.
Moderate rates of foam formation may be harmless. The presence of small, homogeneous particles of large denier in the tank can stabilize the foam layer, but the accumulation of excessive solid particles can cause an explosion. Using activated carbon mat to remove surface active substances, or through filtration to make the foam is not too stable, this is an effective measure; Other measures should also be taken to reduce the amount of surfactant introduced to Z.
