GrasslandFence Mesh What are the characteristics of Fence Mesh commonly used by manufacturers in modern communities?
Community fence net is widely used by modern communities. On the one hand, it has a good security protection effect, and on the other hand, it has both beautiful appearance. The effect can be embellish to the community. Fence Mesh, also called fence mesh, is made of high-quality low-carbon steel wire, galvanized iron wire, welded and welded. Plastic spraying, galvanizing, dipping. So, specifically, what are the characteristics of the fence used for community construction?
First, as for the community fence, its overall strength (strength) is relatively high, so it is very strong in use, and its decorative effect is also very prominent. The second is that the welded joints of the residential fence netting produced by modern fence netting manufacturers (Produce) will be very reliable, which can effectively prevent someone from cutting the fence netting or even malicious damage. The third is the unique (interpretation: unique, special) anti-rust and anti-corrosion technology, because the fence uses not traditional iron bars, and special anti-corrosion processing is carried out during production, so it can be used. Effective anti-corrosion and anti-rust, enhance the service life. Fourth, it is its unique environmental protection. The community fence can be recycled and reused, so it is an environmentally friendly product.
Highway fence net The commonly used anti-corrosion method is the powder dipping method, which originated from the fluidized bed method. The so-called fluidized bed was originally applied to petroleum in the Winkler gas furnace Contact decomposition, and then developed the solid-gas two-phase contact process, and then gradually used for metal coating. Fence nets are also called protective nets. Due to regional differences, southerners are accustomed to calling it "isolation fences, and northerners are accustomed to calling fences. my country's fence nets are mainly divided into: garden fence nets, railway fence nets, bridge fence nets, high-speed highway fences, sports fences, and airports Purse seine, etc. (extremely versatile). The fence post can be round or square, and the mesh grid is mostly rectangular, and the wire warp is relatively large. The mesh body has various forms, simple structure, solidity and beauty, and it not only plays a role of isolation and protection but also a decoration. Therefore, sometimes it is still called the "fluidized bed coating method". The actual process is to add the powder coating into a porous and air-permeable container (flow trough) at the bottom. State", becoming a fine powder with uniform (jūn yún) distribution.
The coating process of highway fence nets is completed in two stages: the first stage is the fixed bed stage, and the second stage is the air delivery stage. On the basis of the fixed bed, continue to increase the flow rate (W), and the bed layer begins. Expansion and loosening, the height of the bed layer begins to increase, and each powder particle is floated, and thus leaves the original position (position) for a certain degree of movement, and then enters the fluidized bed stage. The fence post can be round or square, and the mesh grid is mostly rectangular, and the wire warp is relatively large. The mesh body has various forms, simple structure, solidity and beauty, and it not only plays a role of isolation and protection but also a decoration. The bc section shows that the powder layer in the fluidized bed expands, and its height (I) increases with the increase of gas velocity, but the pressure in the bed (△P) does not increase, and the flow velocity is changed within a certain range without affecting the fluid position. The required unit power (referring to the amount of work done by the object in a unit time) is a characteristic of the fluidized bed, and it is this characteristic that is used to implement the coating process. The uniformity of the powder fluidization state in the fluidized bed is the key to ensuring the uniformity of the coating film (explanation: an important part of the metaphor). The fluidized bed used in powder coating belongs to "vertical fluidization", and the fluidization number must be found through experiments. Generally, it can be coated. The suspension rate of the powder in the fluidized bed can reach up to 30-50 %.
