In addition to logistical challenges, importers must also keep up with changing quality standards and environmental regulations. Titanium dioxide is classified as a potential human carcinogen by the International Agency for Research on Cancer, and there is increasing pressure on importers to ensure that the material meets strict safety and environmental guidelines
1. PVC plastic coated barbed rope adopts flexible structure
Stainless steel barbed rope in the way of corrosion is not too, because the surface is not processed but depends on its own raw materials for corrosion resistance, so there will be no chemical reaction. After a long time of use, will not be similar to hot dip galvanized barbed rope surface corrosion coating problems will rust, because the stainless steel barbed rope internal material and the surface of the material is the same.
Galvanized electric welding net is widely used in industrial production, agriculture, engineering construction, transportation, mining and other processing and manufacturing industries. Such as machinery and equipment protective cover, animal guardrail, pot flower guardrail, window fence, safety exit guardrail, poultry cage, egg basket and home office food industry basket, paper basket and design decoration. It is suitable for general engineering building wall, pouring concrete, multi-storey building, etc., which plays an important structural role in the thermal insulation system. In the construction of the building, the thermal insulation board of hot-dip galvanized electric welding grid is placed on the inside of the outer mold of the wall to be concreted. The external thermal insulation board and the wall are one kind of live, and the thermal insulation board and the wall are integrated into one body after the removal of the mold.
Different supports are used for different installation environments. In the past, the blade barbed wire was not easy to fix, and the installation environment was often steep. Therefore, special tools must be used to fix the blade barbed wire to prevent it from being improperly installed.
- 1. Cleaning: Soak the pre-treated steel wire in detergent to remove surface impurities and dirt.
Most people in addition to pay attention to the price of barbed rope, many people for hot-dip galvanized barbed rope or cold galvanized barbed rope will have questions, in fact, these two products, the price difference is not very big, so how to choose hot-dip galvanized barbed rope and electric galvanized barbed rope?
If the zinc coating is good, but in 3% nitric acid when the light, the coating has dark shadow, passivation occurs when the film is brown, may be caused by foreign metal impurities such as copper or lead in the galvanizing liquid. When problems occur in the process of galvanizing large coil galvanized wire, the temperature and current density are checked first, and then the content of zinc and sodium hydroxide in the plating solution is measured and adjusted through the analysis of the plating solution. Whether DPE content is low can be determined by hull cell test.
- 2, oil: it is recommended to use cloth (there is a kind of textile cloth for polishing glasses, do not knit, because the nap is easy to fall off), oil to the inside and outside of the cage. The amount of oil is not much, because the bamboo material is old, density and hardness are relatively high.
Post time: 19-12-22Galvanized welding net is currently a large use of galvanized wire drawing products, galvanized welding net is divided into cold galvanized welding net and hot galvanized welding net. The price of cold galvanized welding net is cheaper than that of hot galvanized welding net, and the anti-corrosion performance is worse. Production process standard for cold galvanized electric welding mesh. The selection of galvanized electric welding net uses Q195 low-carbon metal wire, the wire rod is drawn by wire drawing machine.
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.
Pet cages have many kinds, the selectivity is relatively large, pet cages are generally made of a little thick wire, and then at the bottom of the base with wheels, so a simple pet cage is made, at the bottom of the wheels is to facilitate the movement of a pet cage, but also should be made in suitable position in addition to a door, Convenience comes in handy when it comes to pet feeding.
- C, coating uniformity: galvanized layer is basically uniform with copper sulfate solution test etched five times without exposing iron.
Post time: 16-03-23The distance between the adjacent two thorn rope installation do not know whether you have noticed? Careful observation can find that its spacing is not the same, the thorn rope factory for customer consultation when asking the installation height of the reason.
Hot dip galvanizing is to remove oil from the workpiece, pickling, dipping, drying after dipping into the dissolved zinc solution for a certain time, can be brought out. Hot dip galvanizing is an effective way to prevent corrosion of metal. It is mainly used for metal structure facilities in various industries. It is to immerse the steel parts after rust removal into the melting zinc liquid at about 500℃, so that the surface of the steel members is attached with zinc layer, so as to play the purpose of anti-corrosion. The galvanized layer is more firm.
- The common barbed rope produced by the manufacturer is the 14*14 type of barbed rope product. Since the warp wire used is the same as the wire diameter of the barbed rope, it is easier to calculate the length and weight. Usually each kilogram of barbed rope can reach about 10 meters of service length. The length of each kilogram of raw material is about 35 meters. Since 35 meters of raw material wire diameter can produce 10 lengths of barbed rope cost.
Moderate rates of foam formation may be harmless. The small homogeneous particles with large denier in the tank can stabilize the foam layer, but the accumulation of too many solid particles will cause explosion. Using activated carbon mat to remove the surface active substances, or through the filtration of foam is not very stable, this is an effective measure; Other measures should also be taken to minimize the introduction of surfactant.
- (2) can be used as breeding net, sheep net, cattle net, chicken and duck, isolation chicken and duck house, play the role of poultry protection;
- For example, if the barbed rope is used to circle, the cost per meter is only a few yuan, if the ring with other products, it may be more than ten yuan or even 20 yuan, which undoubtedly increases the cost of the user again, so the cattle and sheep with barbed rope is the most economical product
- 2, galvanized welding mesh away from acid and alkali corrosion effect of acid and alkali is electric welding mesh. If the electric welding mesh is accidentally stained with acid and alkali, it should be immediately washed with clean water, and then dried with dry cotton cloth.
The external environment has a great influence on the storage of cold drawn wire. Especially during the rainy season, special attention should be paid to the air humidity of workshops and warehouses. It is recommended to use moisture test paper with a value between 8 and 10. If the PH value is high, attention should be paid to the corrosion of the internal cold drawing wire. Cold drawing wire in normal environment storage for two years no problem, cold drawing wire will not be corroded. However, it is necessary to place the coil gently during the handling process to avoid the winding position leading to the cable is not smooth.
Flood control and flood information. Can also be used for handicrafts manufacturing, machinery and equipment of transport network mountain beautification network – high strength wire grille (hook flower net, rhombus net) the use of mountain flowers network protection principle, hook flower net, mesh uniform, flat surface, weaving concise, crochet, beautiful generous, wire mesh, mesh with wider picture, diameter of thicker, not easy corrosion, taking a long, and strong usefulness.
The formation process of hot dip galvanized layer is between the iron matrix and the outside of the pure zinc layer, the formation of iron-zinc alloy process, the workpiece surface in hot dip plating when the formation of iron-zinc alloy layer, so that the iron and pure zinc layer is well combined. The process of large roll galvanized wire can be simply described as: when the iron workpiece is immersed in the molten zinc liquid, the first zinc and α-iron (body-centered) solid melt is formed on the interface. This is a crystal formed by the matrix metal iron dissolved with zinc atoms in the solid state. The two metal atoms are fused with each other, and the attraction between the atoms is relatively small.
There is a connection between the hook mesh and the aperture, in short, the general hole small hook mesh, the wire is also very small; Aperture is large, hook mesh wire is generally larger. The weaving of the hook mesh also has certain rules, using the first pre-bent into a wavy wire, and then woven into the hook mesh. According to the knitting method, the hook mesh can be divided into: closed weaving, two-way plain weaving, one-way corrugated weaving, two-way plane weaving, two-way corrugated weaving, rectangular hole weaving.
There are three methods to detect the thickness of zinc layer of galvanized wire: weighing method, cross section microscopy method and magnetic method, among which the first two experiments will cause certain damage to galvanized wire, including the length of galvanized wire and the reduction of dosage. The general detection of galvanized wire galvanized layer is detected by magnetic method, which is also a more intuitive and convenient method. The standard of galvanized layer thickness is related to the wire diameter of galvanized wire. The larger the wire diameter of galvanized wire, the thicker the galvanized layer is. It is the thickness of galvanized layer and cast iron after centrifugal separation.
- 2, oil: it is recommended to use cloth (there is a kind of textile cloth for polishing glasses, do not knit, because the nap is easy to fall off), oil to the inside and outside of the cage. The amount of oil is not much, because the bamboo material is old, density and hardness are relatively high.
Use in daily life does not need to carry out maintenance and maintenance, save a lot of time, but also save maintenance and maintenance costs. The annealed wire has good stability and corrosion resistance, which greatly prolongs its service life. There are many kinds, which can be selected according to different uses.
