Production process classification of nickel mesh
Nickel mesh includes nickel plate mesh and nickel wire woven mesh. Nickel is magnetic and belongs to transition metal. Approximately silver-white, hard, ductile, and ferromagnetic metal element. It is highly polished and resistant to corrosion. After being dissolved in nitric acid, it turns green. At room temperature, nickel forms a dense "oxide film" on the surface in moist air, which not only prevents continued oxidation, but also resists corrosion from alkali and salt solutions.
According to the production process, nickel mesh is divided into nickel wire woven mesh, nickel plate stretched mesh, and nickel plate perforated mesh.
1. Nickel wire woven mesh: It is made by cross-weaving nickel wire with warp and weft, and generally adopts plain weaving process with square mesh. Mesh number: 0.2-250 mesh.
2. Nickel plate stretched mesh: It is formed by punching and drawing nickel plate or nickel foil by machine, the mesh is diamond-shaped, and the mesh specifications are: 0.3X0.5mm, 0.5X1mm, 0.6X1.2mm, 0.8X1.6mm, 1X2mm, 1.25X2.5mm, 1.5X2mm, 1.5X3mm, 2X2.5mm, 2X3mm, 2X4mm, 3X6mm, 4X8mm, 5X10mm, etc. The net thickness is 0.04mm smaller and 5mm larger.
3. Nickel plate punching mesh: punching holes on the surface of the nickel plate by mechanical punching. The mesh shapes are round, semicircle, crescent, triangle, rectangle, hexagon, triangle, inline, square, trapezoid, etc. The net thickness is 0.04 mm-5 mm.
