What is the test method for stainless steel screen mesh?

Stainless steel mesh uses: hospital, pasta, meat barbecue, life basket, fruit basket series to stainless steel mesh-based, using electrolytic polishing technology for surface treatment, the surface as bright as a mirror. Here is the stainless steel wire screen test method, the test accuracy of braiding accuracy is divided into three levels: first-level accuracy, mesh deviation can not exceed 6% ; second-level accuracy not exceed 9% ; third-level accuracy not exceed 12% ; It is mainly about the inspection of mesh arithmetic mean and the inspection of large mesh size. What is the test method for stainless steel wire mesh? Woven wire mesh quality inspection in the production process there can not be no manufacturing defects, in general, coil delivery of metal mesh. Serious skew, weaving width on the net surface warp and weft wire verticality is greater than 4 degrees; large area multiple creases; radial large mesh over tolerance, large area density error; large area run weft, uneven surface; The diameter of warp and weft silk is seriously out of tolerance, holes, half weft, Big Fork, large area of serious uneven color difference, serious mechanical damage. No defects, a small number of important defects, and general defects are allowed. Major defects mainly refers to: warp and weft interweave is not firm, with two fingers up and down rubbing, warp and weft wire has obvious loose displacement phenomenon, rolling serious, mesh is larger than or equal to 0.18 mm, the natural curling diameter of 1m mesh is less than 80mm, the mesh is less than 0.18 mm, and the natural curling diameter of 1m mesh is less than 60mm.
