3. Put zinc block into the plating aid pool regularly, so that the bivalent iron in the plating aid becomes trivalent iron, and it is an important measure to stabilize the PH value in a numerical range. At the same time, it is convenient for the filter to filter out the trivalent iron ions in the plating aid; Ferric ion is controlled between 0.3 and 1.0g/L; When hydrogen is not released in the plating aid, the zinc block is continued. It is an effective measure to reduce zinc slag, improve the fluidity of zinc liquid and reduce the thickness of zinc layer to play the role of plating aid filter.
Galvanized 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.
The technical term “galvanized” means that metal has been specially treated with zinc. Essentially, the wire is covered with a very thin layer of zinc. It is this thin layer of zinc that gives galvanized wire its many properties. Galvanizing can be done by dipping wire into a pool of zinc or by electroplating. Are you familiar with galvanized wire mesh? Do you know what to pay attention to in the process of use?
The second is according to the barbed wire material to determine the importance of the process, it is especially embodied in hot dip galvanized barbed wire, because of the different treatments of barbed wire in wire material and ductility have some discrepancy, if not pay attention to in the process it is easy to damage on the surface of zinc layer, directly affect the barbed wire rust resistance.
- One is to do a good job of galvanized wire packaging, avoid bump, to ensure the integrity of the zinc layer;
Environmental factors should be considered when choosing the thickness of galvanized layer. Galvanized wire in galvanized, pay attention to the above problems, can be well galvanized, to ensure the quality of galvanized wire. Galvanized methods are mainly divided into two types, one is hot dip galvanizing method, the other is electric galvanizing method. This paper mainly introduces the method of galvanizing. Electrogalvanizing is an electrolyte used for galvanizing.
Three methods of twisting the thorn rope: forward twisting, reverse twisting, reverse twisting.
The barbed wire factory will store the inventory of the barbed wire blade in the appropriate place because of the understanding of the product characteristics.
We can complete the installation of ordinary double-strand barbed rope by using wood shaft or even trees, but the blade barbed rope has high requirements for construction.
Post time: 14-04-23- The key and important parts with tensile strength greater than 1034Mpa should be relieved of stress at 200±10℃ for more than 1 hour before plating, and the carburized or surface hardened parts should be relieved of stress at 140±10℃ for more than 5 hours. The cleaning agent used for cleaning shall have no effect on the binding force of the coating and no corrosion on the substrate. Acid activation Acid activation solution should be able to remove corrosion products and oxide film (skin) on the surface of parts without excessive corrosion on the matrix.
The shape of the cage has round, square, octagonal, hexagonal and other shapes. Because the circular space uses a large area, it is more suitable for the activities of birds, and it is not easy to get hurt, so it is popular with everyone. A cage is dear to a man who loves birds, for it is inhabited by his master’s birds. If well maintained, it can be maintained for many years. Let’s look at how to maintain the cage.
With the development of mining industry, pig iron classification in Our country has been very extensive, can satisfy the demand of machinery industry. In general, iron used to produce large coils of galvanized wire can be divided into two classes. A metal produced directly from iron ore and iron smelting, consisting of iron oxide, silicon dioxide, and other miscellaneous stones. When this ore is specially refined into metal iron, carbon, silicon, manganese, and other elements are mixed in, so that the refined material is called general pig iron, is also for the initial grade of the material.
Wire mesh production of general selection of low carbon wire, after fine and accurate active welding equipment processing, the selection of galvanized process surface treatment. After the completion of the product, the net surface is smooth and regular, good integrity, strong and consolidated, even if part of the choice or pressure will not appear lax phenomenon.
- Compared with hot-dip galvanized barbed rope, it is much better in the circle of mountains and forest protection. Because it can choose several colors on its appearance, different sites have different colors, which is both beautiful and practical, so as to facilitate the growth of natural plants and gradually recover the original ecological environment.
Galvanized hexagonal mesh features: easy to use; Save transportation costs. It can be reduced into small rolls, and involved in moisture-proof paper packaging, occupying little space. Coating thickness uniformity, corrosion resistance is stronger; Simple construction, no special technology; Strong resistance to natural damage and corrosion resistance and the ability to resist adverse climate impact; Can withstand a wide range of deformation and still not collapse. Play the role of fixed heat preservation and insulation.
Now it is more used in the binding of the construction industry. Compared with ordinary iron wire, it is softer and has better luster. Use in daily life does not need to carry out maintenance and maintenance, save a lot of time, but also save the cost of maintenance and maintenance. Annealed wire has good stability, good corrosion resistance, greatly prolonging the service life. More kinds, can be selected according to different uses, making annealing wire device is simple, improve the utilization rate of the device. The material properties of annealed wire can meet different processing requirements.
- The quantity should be the same as the contract, cold drawing, carefully record the quantity of each specification and packing method. If there is a label, check whether the label is correct and take a photo to confirm. Each roll of iron wire is fastened with galvanized packing tape, and then tightly bound with a very strong transparent plastic bag. The outer layer of coated iron wire is wrapped with white braided cloth, and the outer layer of galvanized iron wire is wrapped with green braided cloth, so as to ensure that the packaging will not be lax in the transportation process. One end of the wire must be clearly marked and the other end left on the outer layer for easy connection by other wires.
Post time: 07-06-24- 4. Keep the rinse water clean after pickling the steel wire
Hot – plated wire average performance: reflected in its cross – section, longitudinal uniformity. In the actual process of operation, such as steel wire jitter, the surface scum plating pot and other reasons will cause the surface of galvanized wire galvanized layer accumulation, should strive to solve the problem. In addition to these reasons, we should pay attention to the tooling and process must be stable, and regular testing should be done to ensure the uniformity of the galvanized layer.
For the specification of galvanized wire, the galvanized wire produced by our factory can range from No.8 to No.22, which refers to the BWG standard, that is, from about 4mm to 0.7mm, which can basically cover the type required by the customer. As for the raw material of galvanized wire, normally, we use Q195 mild steel, and some factories will also use SAE1006 or SAE1008. The following is the zinc coating, for galvanized wire, this is very important, the general zinc coating is about 50g/m2 to 80g/m2, some customers need high zinc galvanized wire, zinc coating can reach 200g/m2 to 360g/m2. The tensile strength of galvanized wire is usually 350n/m2 to 800n/m2. Then there is the packaging specification of galvanized wire. The specifications of small rolls of galvanized wire are 50kg/ roll, 100kg/ roll and 200kg/ roll. Of course, there are large rolls of galvanized wire, the weight can reach 300kg/ roll or 800kg/ roll.
Post time: 24-10-22Large hexagonal net called the 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.
In the electroplating tank through the current unidirectional make zinc plating on the metal surface gradually, the production speed is slow, the coating is uniform, the thickness is thin, usually only 3-15 micron, the appearance is bright, smooth, beautiful, poor corrosion resistance, generally will rust in a few months. The production process of hot wire plating mainly includes: preparation of the original plate → pre-plating treatment → hot dip plating → post-plating treatment → finished product inspection, etc. According to custom often according to plating pretreatment method.
3, a wide variety of specifications, a variety of shapes you choose, both European and American style and today’s popular fashion, full noble and modern beauty.
Electric galvanized wire shiny white, galvanized wire to exist in a dry and ventilated environment, can not exist in a humid environment. Galvanized wire can not be put together with acid and alkaline substances to prevent chemical reactions and corrosion of galvanized wire. Galvanized wire must also be placed flat to prevent tortuous deformation.
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.
