Pet cage has many types, and selective is bigger, pet cages are generally made of wire, with better coarse, then at the bottom with a wheel base, such a simple pet basket was made, in the wheel at the bottom of the mount is for the convenience of the mobile, a pet cages should also adapt to the location of the production in addition to a door, Convenient in pet feeding when more convenient.
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.
Zinc is a silver-white metal, brittle at room temperature, soluble in acid can also be soluble in alkali, known as amphoteric metal. Pure zinc in dry air is more stable, in humid air or containing carbon dioxide and oxygen water is small, the surface will generate a layer of basic zinc carbonate based thin film layer, it can delay the corrosion rate of zinc layer. The corrosion resistance of zinc coating in aqueous solution of acid, alkali and sodium chloride is stronger.
Therefore, the rust of galvanized black iron wire has a great relationship with storage. At the same time, after rust, it should also be reasonable for post-treatment to avoid affecting its use effect. Of course, when the black iron wire is galvanized, the thickness of the galvanized layer should be ensured, so that the possibility of rust can be reduced. Speaking of galvanized iron wire, perhaps many people think it is relatively rare, in fact, it is not.
Some raw materials in the production of unstable processing, the wire itself will exist burr, surface small pits and other local defects. Galvanized steel in galvanized, generally should pay attention to the galvanized layer protection time of galvanized wire, and the thickness of galvanized layer has a great relationship. Generally speaking, when the main gas is relatively dry and used indoors, the galvanized layer thickness of galvanized wires is only 6-12μm, and under relatively harsh conditions, the galvanized layer thickness of galvanized wires needs 20μm, and can be predicted to reach 50μm.
For example, in gray iron, its carbon exists in iron ore in the form of graphite, the crack is often gray, soft and tough, simple filter cutting, suitable for casting. In the white iron, the carbon and iron are combined to form iron carbide, the crack appears white, the quality is very strong and brittle, and it is the material of malleable steel. Alloying grade is composed of various alloying elements with different composition and structure.
The welding process of galvanized steel wire mesh because of low carbon steel carbon content is low, manganese and silicon content is low, will not occur severe hardening or quenching structure due to welding. The low carbon steel joints have excellent plasticity and impact toughness after welding. In the welding process, it is generally not necessary to preheat, interlayer temperature control, post-heating control and heat treatment to improve the welding structure.
