They can be customized to meet specific project requirements, allowing for a tailored fit in various pipe sizes and pressure ratings They can be customized to meet specific project requirements, allowing for a tailored fit in various pipe sizes and pressure ratingsfrp flange. Furthermore, their ability to withstand high temperatures and pressures makes them suitable for both low-pressure and high-pressure systems.
Appellation: Hook fence is a variety of guardrail. The diameter of the opposite side of each mesh is generally 6.5cm-14cm. The thickness of the wire used is generally from 3.5mm to 6mm. Wire material is generally Q235 low carbon wire. The wire is welded by gimmick into decorative hook mesh black. The general size of the net is 1.5 meters X4 meters, 2 meters X4 meters, 2 meters X3 meters. The general surface treatment is cold (electric) galvanized treatment. There are also hot dip galvanizing, dip plastic, spray plastic. But overall, 99 percent is cold (electric) galvanized.
When the zinc layer is seriously damaged and endangers the iron matrix, the zinc will produce electrochemical protection on the matrix, the standard potential of zinc is -0.76V and the standard potential of iron is -0.44V. When zinc and iron form microbatteries, the zinc will be dissolved as the anode, and the iron will be protected as the cathode. Obviously, the atmospheric corrosion resistance of hot dip galvanizing is better than that of electric galvanizing.
The 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.
Compared with electric galvanized iron wire, hot dip galvanized iron wire has higher zinc layer, better anti-corrosion performance, and is suitable for the more important anti-corrosion and anti-rust status.
1. PVC plastic coated barbed rope adopts flexible structure
The lighting surface of each type of shed is designed to be curved, improving the Angle of the light surface, because the lighting surface is curved, no dust accumulation, good light transmittance, high temperature in the shed, after measurement, the average temperature in the shed is 3℃ higher than the traditional bamboo pole cement column shed, the yield is increased by 15~20%, and the harvest date is advanced. The formula is scientific, the surface does not absorb moisture, do not return halogen through modification technology and scientific production process, solve the greenhouse frame rod is easy to absorb moisture return halogen, poor water resistance and easy to change the shortcomings, so that the greenhouse steel pipe in the high temperature and high humidity environment, few drops, frost phenomenon, and reduce pests and diseases.
Removal of surface-active substances by activated carbon matting. Or make the bubble unstable according to overworry, these are all reasonable countermeasures; Other strategies should also be used to minimize the amount of surfactant taken in. The introduction of organic matter can make the electroplating process speed drop sharply. Galvanized iron wire blackening can be effectively prevented, such as: the work site to keep dry, reduce and do not use chemicals, operators with clean gloves and so on. In addition, hot dipping zinc factory can be required, after dipping zinc must be passivation treatment, passivation treatment of zinc has a better anti-discoloration effect, can effectively prolong the discoloration time, the combination of the two, discoloration should be able to solve. Galvanized iron wire has good toughness and elasticity, the amount of zinc can reach 300 g/square meter. It has the characteristics of thick galvanized layer and strong corrosion resistance.
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.
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.
Greenhouse special electroplating process iron wire blackening solution:
Large roll galvanized wire welding net is made of high quality galvanized wire welding net, wire through the current, after mutual melting, strong connection point, and the formation of metal mesh. In the use of galvanized iron wire to find the thickness and soft and hard to the size of flowers, weight and softness corresponding to the degree, too soft florets to use fine wire, and heavy flowers, flowers with thick stems to use thick wire.
Galvanized wire mesh is divided into hot dip galvanized wire mesh and cold galvanized wire mesh. Galvanized steel wire net selects the high quality low carbon steel wire, iron wire factory made by precision of automation machinery welding technology processing, smooth surface, firm structure, integrity is strong, even if the local cutting of galvanized steel wire net, or local also under pressure from loose phenomenon, after molding, wire mesh galvanized corrosion resistance good, has the advantage that the general steel mesh does not have.
Poor pretreatment before plating; Bath temperature is too low; Poor quality of additives or too many additives and organic impurities will cause poor bonding. The quality of additives also has an effect on coating foaming. Some additives react incompletely during synthesis and continue to polymerize during long-term storage or use. The additive tends to distort the crystal lattice and cause stress, causing the coating to bubble.
Hexagonal mesh is also known as twisting mesh, thermal insulation net, soft edge net. It is made of single – layer mesh. Its mesh, mesh wire, galvanized and PVC film properties and the same as the cage. This product can be different shapes and sizes of the block stone into the alloy net to form a flexible whole, can be lifted, car, shipping to the designated place, the alloy net connected to each other into a larger whole, construction throwing convenient, fast, good economic performance.
Secondly, the zinc-iron alloy protective layer of hot-dip galvanized wire has self-healing properties. When the surface of hot-dip galvanized wire is damaged or scratched, zinc metal can form zinc ions through electrochemical reaction, self-healing repair of the damaged zinc-iron alloy protective layer, so as to maintain the corrosion resistance of the steel wire. This self-healing property enables the hot-dip galvanized wire to be quickly repaired during use, even if there is a slight scratch or damage on the surface, avoiding further corrosion. After the ordinary steel wire is damaged on the surface, it is often unable to repair itself, which is easy to lead to the diffusion of corrosion and accelerate the aging and damage of the steel wire.
Customers in the order of wire mesh will often shop around, most customers are in comparison with manufacturers to give the product price, the company tells you, do not blindly compare the price. To standards, production technology, manufacturers and other factors lead to different prices.
Its specific design layout principle is:
When galvanized wire is galvanized, it is generally necessary to pay attention to the following problems: the duration of the protective effect of galvanized wire is greatly related to the thickness of the coating. Generally speaking, in the dry main gas and in indoor use, the thickness of galvanized wire galvanized layer only 6-12 μm “, and in harsh environmental conditions, galvanized wire galvanized layer thickness needs 20μm “to B height up to 50μm”. Therefore, the environmental impact 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.
When using these two products, it is obvious that there is a gap between them. By pulling or bending the wire, it is often difficult to restore the original, for example, if the same place is repeatedly bent, it will be found that it has broken, and the cold drawing wire will not. Cold drawing wire compared with iron wire, its hardness, tensile resistance, bending ability is greatly enhanced, suitable for building materials.
