Inspection of weaving quality. It is impossible for metal wire mesh to have no manufacturing defects in the production process. Under normal circumstances, metal mesh delivered in rolls is not allowed to have major defects, allowing a small number of

The following conditions of the stainless steel filter mesh on the weaving
process are major defects: the warp and weft are not firmly intertwined, and the two fingers are used to move up and down, and the warp and weft yarns have obvious loose displacement; the winding is serious, the mesh is greater than or equal to 0.18 mm, and the mesh is 1 m long. The natural curl diameter is less than 80mm; the mesh is less than 0.18mm, and the natural bending diameter of the 1m long mesh surface is less than 60mm, which should be judged as unqualified.
