The temperature of large roll galvanized wire should be controlled at 30 to 50℃ during electroplating. Because the chloride ions in the bath are very corrosive, quartz glass heaters are generally used. Continuous production does not need heating, but needs cooling. Cooling can be in the groove side row thin wall plastic pipe, through the flow of tap water cooling, can also be used as a titanium pipe temperature control device.
Post time: 19-05-22- 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.
- Packing and binding galvanized wire is in the liquid state of zinc, after a messy physical and chemical effect, not only on the steel plated thick pure zinc layer, and also generate a zinc-iron alloy layer. This kind of plating method, not only has the corrosion characteristics of the electric galvanized wire, and because of a zinc alloy layer. It also has strong corrosion resistance that can not be compared with electric galvanizing. Therefore, this plating method is particularly suitable for a variety of strong acid, alkali fog and other strong corrosive environment.
- The drawing process of waste product drawing process has a great influence on product function. Generally, large total surface reduction rate (see area reduction rate) and small pass surface reduction rate (about ≤23%) are selected to ensure the tolerance of products. About high strength spring steel wire, the exit temperature of each pass steel wire should be controlled when drawing below 150℃, to prevent the steel wire from changing cracks due to strain aging, which is the main disadvantage of steel wire obsoletion.
Post time: 10-06-22A. When the thickness of the plating is 3-4 mm, the zinc adhesion should be less than 460g/m, that is, the average thickness of the zinc layer is not less than 65 microns.
- 4, safety, environmental protection, harmless to people (livestock), even if it does not intend to touch the guardrail will not hurt like steel, iron guardrail. Stainless steel wire mesh can be used as poultry cage, egg basket, channel fence, drain tank, porch guardrail, anti rat net, mechanical protective cover, livestock and plant fence, grid frame, etc.
- At present, it is recognized that the best surface treatment method for rust prevention is to make dacron rust. Generally, auto parts have been used this method for rust prevention. The salt water test generally lasts more than 96 hours. But if the hardware is used in very poor conditions, there are also people who use “asphalt” which is tar to do the surface treatment.
2. Stainless steel 316 material should be used in coastal areas, which can resist corrosion of sea water.
- Weigh each reel of wire of different specifications, not less than the reel weight required in the contract, and record the value. Contact detection. No contacts are generated for each reel of wire. If there are contacts, no more than three contacts are generated for each reel. Each contact should be smooth surface treatment, the wire can not be pulled off from the contact, in line with customer packaging requirements.
Breeding cattle and sheep with barbed rope effect is better, because the advantages of more barbed rope. So is the thorn rope used to do animal husbandry good?
- Galvanizing can be done by zincate galvanizing or chloride galvanizing. Appropriate additives should be used to obtain a coating that meets the requirements of this standard. Light treatment should be carried out after light plating. The parts that need to be dehydrogenated for passivation should be passivated after dehydrogenation. Before passivation, 1%H2SO4 or 1% hydrochloric acid should be applied for activation for 5~15s. Passivation shall be treated with colored chromate unless otherwise specified in the design drawings.
There are still some differences between the welding mesh and the wire mesh and the steel mesh. This mesh is mainly a welding mesh made of high quality low carbon steel wire straightened and cut, and then welded with electric welding equipment. It can be said that because of the characteristics of fast production and convenient transportation, it has been applied to many industries. The application of welding mesh in the industry, because the mesh has strong corrosion resistance and uniform mesh. It has become a special grid for floor heating in the building industry and has been applied in many fields.
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.
- Electric welding net welding after galvanized is after the completion of the welding and then cold galvanized or hot galvanized; After the first galvanized welding is to change the wire welding mesh, welding can be seen after the completion of the welding spot; The two processes are different prices are also very different, the cost of the first plating after welding is low, the surface is smooth, and the cost of the first welding after plating is higher, not easy to rust.
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.
1. The diameter of the raw material and the thickness of the diameter are directly affected;
Post time: 03-02-23The error of construction welding net diameter should be controlled at 0.02 mm. For example, we buy wire diameter of 89 wire welding net, with a micrometer to measure the diameter, the diameter of the allowable range is 87 -91 wire. In this range is qualified welding net. Because the accuracy has been compared, but no one can control it so well in the production process. The welding net can be accurate to 0.01 mm, so the error is allowed.
However, because the bath contains highly toxic cyanide, the gas escaping from the electroplating process will do great harm to the health of workers, and its waste water must be strictly treated before discharge. Galvanized iron wire has good anti-corrosion and anti-rust ability, so it can be used in some outdoor guardrails or fences, especially on handicrafts, which are also of great use. Galvanized iron wire is not easy to rust and oxidation on the surface.
- Wire diameter: 6#–20#, this kind of wire mesh is braided by low carbon steel wire; Aperture: 15′-15′ extra standard can be customized according to customer requirements. Usage: To be used for road beautification with protective net, maintenance and support of seawall, hillside, dam, etc., is a good data to avoid landslides.
Post time: 28-06-22- The application of electric welding network is more and more widely, and the technology is gradually mature, electroplating rust prevention, plastic processing, used for breeding, grille, coupled with the framework made of guardrail network.
- 3, barbed rope protection net in the bridge, channel, should be toward the bridge head cone slope (or end wall) direction surrounded, should not leave for people, livestock can drill into the gap.
Post time: 22-09-22- U nail price selection of galvanized iron wire, hot dip galvanized iron wire and black iron wire and other high-quality wire, welded, PVC or PE, PP powder after curing coated its surface, with strong adhesion, good corrosion resistance, bright color and so on.
