Nowadays, chain link fences are used more and more widely in life, and its demand is gradually increasing. Most of chain link fences are placed outdoors. People will ask for hooks if they are exposed to wind, sun and rain every day. How does the flower guardrail prevent rust in this environment?
First of all, the chain link fence is to prevent rust by changing the internal structure of the chain link fence. For example, it is made of various corrosion-resistant alloys, such as adding chromium and nickel to ordinary steel to make stainless steel. Protective layer method: Cover the metal surface with a protective layer to isolate the metal product from the surrounding corrosive medium to prevent corrosion. Use electroplating, hot-dipping, spraying, dipping, spraying and other methods on the stadium fence to cover the surface of the silk with a layer of anticorrosive plastic to prevent the corrosion of steel by water and air.
The difference between chain link fence dipping and fence net spraying:
1. From the appearance point of view, the skin of the plastic-dipped fence is thicker than the plastic-sprayed fence. The plastic can reach 1mm, while the spray can only reach 0.2mm. It can be known from the wall thickness of the plastic dipping skin that the plastic dipping fence is suitable for outdoor use, while the plastic spraying fence is suitable for indoor use.
2. In terms of details, the plastic-dipped fence net looks lubricated, while the plastic-sprayed fence net can also see the working points (soldering points) during welding, so the plastic-dipped fence net is more.
3. The plastic-dipped fence netting is smooth when touched by hand, and feels like wax, while the plastic-sprayed fence netting feels rough (not too obvious that it is easy to notice when the two are contrasted).
4. In terms of the price of the fence, the same screw, sprayed fence is cheap. The price of the same finished silk warp and plastic-dipped fence is cheap. This is also the reason why the most commercial dipping fence nets are purchased.
The similarities of chain link fence dipping and fence net spraying:
They are all made of pvc (polyethylene), odorless, non-toxic, feel like wax, have excellent low temperature resistance (the lowest use temperature can reach -70～-100℃), good chemical stability, and can withstand most acids and alkalis. (Not resistant to acids with oxidizing properties), insoluble in general solvents at room temperature, and low water absorption. Stable; not easy to be corroded by acid and alkali; heat resistant and flame retardant (flame retardant value above 40).
