- Common galvanized iron wire equipment is usually used in the barbecue net, barbecue net generally requires to have a long service life, with galvanized iron wire equipment to the wire on a layer of zinc, barbecue net is not easy to be corroded.
- 4, barbed wire protective net and culvert intersection, such as the ditch is narrow, barbed wire barbed wire protective net can be directly crossed, the ditch is wide, barbed wire barbed wire protective net is difficult to cross, can take the treatment method of bridge, channel.
There is no adhesion test of powder spraying or fluorocarbon spraying on packaged galvanized wire, but there are two points for reference: first, in sealed or air-free environment, non-metallic volatiles can corrode zinc coating; Second, zinc at higher than 230 degrees (c) will cause the matrix metal brittle. And powder spraying and fluorocarbon spraying are to be baked at a higher temperature and in a sealed environment, causing rapid corrosion of zinc, resulting in loose corrosion film resulting in coating adhesion decline, and even lead to (matrix) steel wire brittle situation may exist.
The cooling circulation system uses spray to cool the drawing die, and takes away a lot of heat generated by the drawing machine in high speed drawing in time to ensure the quality of the wire. Control drawing process parameters: drawing speed 10 ~ 12m/s; Winding tension 8 ~ 10N; Measuring length 30km; The mass fraction of lubricant is 3.5 ~ 4.5%; pH value of lubricant 7 ~ 8; Lubricant temperature 30 ~ 40℃.
In the process of composite plating, it is necessary to stir the plating solution to obtain the composite coating in which the particles dispersed in the matrix metal. Stirring methods include mechanical stirring, air stirring, ultrasonic stirring, bath circulation, etc. In the process of production, the acid activation solution can remove the corrosion products and oxide film on the surface of low carbon steel wire without excessive corrosion on the matrix. Galvanized wire can be used zincate galvanized or chloride galvanized and other processes, appropriate additives should be used to obtain the coating required by the standards of low carbon steel wire.
- Good word of mouth blade barbed rope must be a reasonable evaluation given by consumers after using, this is because many people feel good after choosing the blade barbed rope, whether in terms of safety protection or in the overall decoration and beautification effect is very good, so that in the actual choice will be more assured, In the eyes of many people, the high quality razor cord will not have problems, or the overall service life is really long, so that we can reduce a lot of cost, and can know whether it is the best.
The wire mesh is composed of low carbon steel wire or medium carbon steel wire, high carbon steel wire or stainless steel wire. There are two kinds of manufacturing technology of steel wire mesh, one is the weaving method, the other is the welding connection, the formation of grid.
Because there are many large livestock in pasture, and because of the large cost of development and easy to be destroyed by livestock, galvanized barbed rope is the best choice for enclosure. Pasture installation thorn rope is necessary, wire mesh factory to introduce the role of pasture installation thorn rope。
- Generally speaking, in dry main gas and indoor use, the thickness of galvanized coating is only 6-12μm, but under poor environmental conditions, the thickness of galvanized coating is 20μm, can reach 50μm. Therefore, environmental factors should be considered when choosing the thickness of galvanized layer. Galvanized layer after passivation treatment, can naturally form a layer of bright, beautiful color passivation film, can obviously improve its protective function, decorative.
Large roll galvanized wire is processed from high quality low carbon steel wire rod. Each wire rod rolled by continuous rolling mill is not less than 200kg, but 15% of the number of plates in each batch is allowed to be composed of two, of which the weight of each rod is not less than 80kg, and 4% of the number of plates in each batch is allowed, and the mass of its single wire rod is less than 200kg, but not less than 40kg. Each rod rolled by semicontinuous mill shall not be less than 60kg, and each batch shall be allowed to have 5% disk nitrogen. The mass of the rod shall not be less than 60kg, but not less than 30kg.
- In addition, before the steel wire enters the zinc liquid, covered with a layer of insulation material containing zinc oxide reducing agent, can reduce the heat loss and zinc ash floating. In addition, adding zinc-5% aluminum-mixed rare earth alloy to the zinc solution, when the zinc solution contains 0.002%-0.005% aluminum mass fraction, can obviously increase the brightness of the zinc layer, and prevent the zinc solution surface oxidation caused by excessive zinc ash.
Post time: 14-03-23Hot dip galvanizing is to make the molten metal react with the iron matrix to produce an alloy layer, so that the matrix and the coating are combined. Hot dip galvanizing is to first pickling the iron and steel parts. In order to remove the iron oxide on the surface of the iron and steel parts, after pickling, it is cleaned in the tank of ammonium chloride or zinc chloride aqueous solution or mixed aqueous solution of ammonium chloride and zinc chloride, and then sent into the hot dip plating tank. Hot dip galvanizing has the advantages of uniform coating, strong adhesion and long service life.
- Third, 201 is high manganese content, the surface is very bright with dark bright, high manganese content is easy to rust. 304 contains more chromium, the surface is matte, no rust. Put the two together and you have a comparison. The most important thing is that the corrosion resistance is different. The corrosion resistance of 201 is very poor, so the price will be much cheaper. Because of the low nickel content of 201, the price is lower than 304, so the corrosion resistance is not as good as 304.
No matter how good the quality of hot-dip galvanized barbed rope is, it is only attached to the surface of the wire with galvanized layer, and with the cause of chemical reaction, the zinc layer on the surface will gradually lose its effect because of oxidation reaction, which is more prominent in the humid area of the environment. And because, after all, the wire will rust, so the quality of hot-dip galvanized barbed rope is certainly not up to the level of stainless steel barbed rope.
- Barbed wire manufacturers focus on galvanized barbed wire, hot galvanized barbed wire, blade barbed wire, stainless steel barbed wire, plastic coated barbed wire, reverse screw barbed wire production for ten years.
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.
Thus, when zinc is sufficient in a solid melt, the two atoms of zinc and iron disperse with each other. The zinc atoms in the iron matrix are moved into the lattice of the matrix, and the iron elements are gradually formed into alloys. The zinc composition of iron and intermetallic compound FeZn13 in molten zinc solution and the bottom of hot galvanized sheet can be used as zinc slag. The pure zinc layer composed of zinc leaching solution is hexagonal crystal.
Advantages: The cost of hot dip galvanized rust prevention is lower than that of other paint coating. In suburban environment, the standard hot-dip galvanized rust prevention thickness can adhere to more than 50 years without repair. In urban or offshore areas, the standard hot-dip galvanized rust protection layer can last 20 years without repair. Galvanized layer and steel is a metallurgical connection, into a part of the steel surface, so the durability of the coating is more reliable.
- The acid activation solution in the production process can remove the corrosion products and oxide film on the surface of the low carbon steel wire without excessive corrosion to the matrix. Galvanized wire can be zincate galvanized or chloride galvanized process, should use appropriate additives to obtain the low carbon steel wire standard requirements of the coating. When galvanized wire after light plating should be light treatment. Control the temperature of the bath of galvanized wire.
Post time: 24-05-23
Post time: 10-10-22- The tensile resistance of welding net to 120N, otherwise for unqualified welding net. In this respect, there is no simple way to test the tensile resistance of the welding net, only through professional tools, expert testing to test, we will not introduce in detail. The outcrop on both sides of the welding net should not exceed 2MM. The welding net diameter wire and weft wire crossing place should be welded firmly, but the edge of the welding net to weld firmly weft wire must come out some, to weld firmly, but can not come out too much, generally not more than 2 mm is qualified welding net.
- Through drawing molding, pickling rust removal, high temperature annealing, hot dip galvanizing. Cooling and other technological process processing. Galvanized iron wire selection of high quality low carbon steel raw materials, after drawing, galvanized and other processes. With galvanized layer, strong corrosion resistance, galvanized layer strong characteristics, electric galvanized iron wire is widely used in construction, highway fence, tie, weaving and other industries.
Pay attention to safety in line collection and operation, others without the consent of the monitor, Ben have to get on the bus operation. The reels should be placed lightly, stacked firmly and neatly, not more than 5 reels. Direct contact with acid and alkali must be prohibited. When the acid fog exceeds the specified target of the state, measures should be taken to control it in time, otherwise production is not allowed.
- The drawing process of the waste product has a great influence on the function of the product. The general selection of about 90% of the larger total surface reduction rate (see area reduction rate) and the smaller pass surface reduction rate (about 23%), to ensure the endurance of the product. On the high strength spring steel wire, pulling should be controlled each time the temperature of the steel wire outlet is lower than 150℃, to prevent the steel wire due to strain aging and change the crack, which is the main drawback of steel wire waste.
