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.
The quality of hot-dip galvanized barbed wire is only in the surface of the wire attached to the galvanized layer, and with the reason of the chemical reaction, the surface of the zinc layer will gradually lose its role because of the oxidation reaction, this situation is more prominent in humid areas. And because after all, the steel wire will rust, so the quality of hot-dip galvanized barbed wire is certainly not up to the level of stainless steel barbed wire.
The entire steel surface is protected, and the melted zinc is easily coated evenly, whether in the interior of the pipe fitting in a depression, or in any other corner where the coating is difficult to access. The hardness of galvanized coating is greater than that of steel. The Eta layer of the upper layer of Z is only 70 DPN hardness, so it is easy to be dented by collisions. However, the hardness values of the lower layer of Zeta layer and delta layer are 179 and 211 DPN respectively, which are higher than that of the iron material of 159 DPN. Therefore, its impact resistance and wear resistance are quite good.
Decorative hook mesh selection of stainless steel, aluminum alloy, brass, copper and other alloy materials, through the special process of preparation of hook mesh. It is a silk screen made of decoration. Today we introduce the aperture and wire diameter of the decorative hook mesh.
Wire-wall 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. The coating on the surface of the weld core is called the coating. The coating of electrode plays a very important role in the welding process. If the photoelectrode without drug skin is used for welding, in the welding process, oxygen and nitrogen in the air will invade a large number of molten metal, metal iron and beneficial elements such as carbon, silicon, manganese oxidation and nitriding to form various oxides and nitrides, and residual in the weld, resulting in slag inclusion or cracks in the weld. The gas in the weld pool may produce a large number of pores in the weld. These factors can greatly reduce the mechanical properties of the weld and make it brittle.
For example, Przewalskopeles is a first-class protected animal in China. At present, as long as there are several other przewalskopeles populations around Qinghai Lake in China, according to incomplete statistics, there are only about 1,000 of them left. Stainless steel barbed wire fence net is commonly used in grassland pastoral area of Qinghai Lake, with a height of 1.5 meters.
The application of barbed rope is calculated in accordance with the length, but the purchase of barbed rope is calculated in accordance with the weight of the barbed rope, which causes the user is difficult to count the number of procurement confusion, so we need to understand clearly, a kilogram of barbed rope to less meters? How much does a meter of barbed rope weigh? These two problems, the procurement of thorn rope becomes very simple.
Galvanized hexagonal net features: easy to use; Save transportation costs. It can be reduced to small rolls and wrapped in moisture-proof paper packaging, taking up less space. Coating thickness uniformity, stronger corrosion resistance; Simple construction, no need for special technology; It has strong ability to resist natural damage, corrosion resistance and adverse weather effects; Can withstand a large range of deformation, but still does not collapse. Fixed heat preservation and heat insulation effect.
The production process of stainless steel blade and galvanized blade is basically similar. The blade size is usually determined according to the mold.
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.Cold drawing wire is a metal cold processing, with wire rod as raw material, that is, the mouth of the steel bar. Cold drawing wire is a product produced by a series of processes such as shell stripping, which is a common wire. In the development and production of metal materials, cold drawing wire is a very common material, its performance is good, the range of use is very wide, manufacturers in processing are the use of cold processing to produce.
Galvanized barbed wire as a safety protection of the metal wall, the galvanized barbed wire device also need to be protected for a long time? And how to protect it? Maintenance and protection of galvanized barbed rope. First, we can start from two aspects. One is about the protection of galvanized barbed rope posts.
Barbed wire, on the one hand, is a great protection against livestock theft, because the surface is covered with sharp spikes that make it very difficult to penetrate through the barbed wire. On the other hand, because livestock generally have the habit of bumping, the barbed rope is used to circle, which makes the livestock dare not rush to collide with the barbed rope, so as to save the use cost of users. In fact, after the construction of the power grid does not need to be energized, the only security measures can play the equipment is these galvanized barbed rope, in the choice of time is certainly to choose some of their own needs, and the quality of the product of reliable materials.Wire mesh welding after galvanized is through the end of the welding and then the cold company to make wire mesh wire mesh steel mesh construction mesh floor heating mesh galvanized or hot galvanized. After the first galvanized welding is to change the wire mesh, after the end of welding can see the welding spot; The two processes are different prices are also very different, the cost of the first plating after welding is low, the appearance is smooth, and the cost of the first welding after plating is higher, not easy to rust.
After the optimization of the process, mass production of 0.80mm electro galvanized steel wire electro galvanized zinc layer quality is controlled within 80 ~ 90g/m2, zinc layer quality dispersion is very small; The results show that the average weight of zinc layer is 14.5g/m2, the loss of zinc layer is less than 5%, and the tensile strength of steel wire is 2300 ~ 2500MPa. It not only effectively controls the quality of zinc layer of raw steel wire, but also reduces unnecessary waste and production cost.
Each coil of steel wire shall consist of one wire. The surface of the rod shall not have cracks, folds, scars, ears, layers or inclusions. However, indentation, pits, bumps, scratches and pockmarks are allowed, and the depth or height shall not be 0.2mm. There should be no corrosion and oxidation skin on the surface of the steel wire, and oxidation color is allowed by heat treatment. The surface of the wire is allowed to have scratches not exceeding half of the allowable deviation range of the diameter, and local defects not exceeding the allowable deviation of the appropriate diameter.
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.
Hot-dip galvanized wire has longer service life and better corrosion resistance than ordinary steel wire. Hot dip galvanizing is a method of chemical combination of zinc metal and steel wire surface, through the formation of a strong and self-healing zinc-iron alloy protective layer on the steel wire surface, so as to prevent direct contact between the steel wire and the external environment, reduce the possibility of oxidation corrosion, and extend the service life of the steel wire.
The life of the “wire”, is actually “low carbon steel wire”, carbon content in less than 0.2%. The surface is usually coated with zinc plating because it is easy to rust. Under atmospheric conditions, the galvanized layer will not rust before most of the fall off, relatively soft. The life of the “steel wire”, is carbon content in about 0.6% of the “carbon steel wire”, or carbon content in about 0.8% of the “high carbon steel wire”, they have enough hardness and elasticity after appropriate heat treatment, high strength. Uses such as winding ordinary spring and so on.
6, passivation to remove hydrogen parts should be passivation after the removal of hydrogen, passivation before the application of 1%H2SO4 or 1% hydrochloric acid activation 5~15s. Passivation shall be treated with colored chromate unless otherwise specified in the design drawings.Galvanized iron wire is widely used in construction, handicrafts, wire mesh, highway guardrail, product packaging and daily civilian and other fields.
