Required knowledge of stainless steel wire mesh

The difference in stainless steel wire mesh is mainly the amount of nickel, and the higher the nickel content, the better. Many nickels contain no rust and are not magnetic. The environment used is also different. The different uses of stainless steel wire for stainless steel screens are also different. Stainless steel screens have different materials except for the number of meshes.

Stainless steel wire mesh weaving methods include: plain weave, twill weave, and dense weave. Due to the characteristics of stainless steel, the processed stainless steel wire mesh has high wear resistance, long service life, precise mesh, uniform structure, no curling, easy to use, uniform screen thickness, antistatic, acid and acid resistant. Corrosion, the product has the characteristics of acid resistance, stagnation resistance, temperature resistance, wear resistance, etc. Therefore, in recent years, stainless steel mesh has been widely used in mine, petroleum, chemical, food, pharmaceutical, machinery manufacturing and other industries as a mine screen.

Calibration of stainless steel wire mesh. The inspection of stainless steel wire screens shall be carried out in accordance with the technical requirements of national standards, and the relevant measuring tools and test instruments shall be used correctly. The quality inspection of the stainless steel square hole net is 100% inspection, and the sampling method is not used.

Material inspection: The surface of stainless steel wire should be smooth and bright, and there should be no defects such as longitudinal pull marks, burrs, rust, etc.; wire diameter tolerance should meet the requirements, and the material meets the requirements.

Weaving accuracy test: The accuracy is divided into 3 levels: 1st level accuracy, the mesh limit deviation can't exceed 6%; the second level accuracy is less than 9%; the third level precision is less than 12%; mainly the inspection of the arithmetic mean of the mesh Inspection of large mesh sizes.

Weaving quality inspection: Under normal circumstances, the metal mesh delivered in rolls is not allowed to have major defects, allowing a small number of important defects to exist, allowing a certain number of general defects to exist.
