The main difference of Dalian mesh is that the material is different. Any metal will be oxidized when encountering the atmosphere. The oxidation of stainless steel mesh is the surface. Metal passivation occurs, and then it has the ability to resist rust. If this passivation layer is damaged, the exposed metal inside will be passivated again, so as to protect it from internal corrosion. It's equivalent to self-healing, and self-protection.
Stainless steel mesh is made of stainless steel wire, which is divided into 201, 302, 304, 316, 316L, zinc nickel alloy, Hastelloy and other materials. It has strong acid resistance, alkali resistance and corrosion resistance. It can be used for several years without rust. Screen doors and windows must be set in restaurants, canteens, food workshops, deli and other places where various kinds of directly imported food are produced and sold.
Sell cooked food, pastry and other facade stores (stalls) to set up cupboards and screens to prevent flies from contacting food. Soybeans and other food drying protection plays a great role in some household products can be used, such as mechanical shield, window screen can be used. The coil shape is flexible, the length is not limited to be customized according to the requirements, and the use is also simple.
The main material of the fence is low-carbon steel wire welded. Iron is an oxide. The water molecules in the air will rust, and the rusted iron will become fragile and loose for a long time. At present, the anti rust treatment methods for the surface of wire mesh fence include cold (electric) galvanizing, hot galvanizing, plastic dipping, plastic spraying, plastic spraying, paint baking and other processes.
Dalian pet cage is now mainly used cold galvanizing, hot galvanizing, plastic spraying, plastic dipping these four major antirust technology. If the surface is treated by dipping or spraying, it can be cleaned by high-pressure water spraying. Dip or spray molding is a kind of plastic coating treatment, the main raw materials are PVC and polyethylene, that is to wrap a layer of plastic to the wire, to block the wire mesh and air oxidation.
