Stainless steel wire mesh screen inspection shall be carried out in accordance with the national standard of technical requirements, the correct use of the measuring and testing instruments.
Stainless steel square hole network quality inspection is 100%, not the sampling method.
Stainless steel wire diameter and deviation, material test of stainless steel wire surface should be smooth and bright, can not have longitudinal tensile mark, burr, rust and other defects;
Wire diameter tolerance should comply with the regulations, the material meets the requirements.
Weave precision inspection accuracy is divided into three levels: level of precision, mesh limit deviation is no more than 6%;
The secondary accuracy is less than 9%;
Level 3 accuracy is less than 12%;
Mainly is the mesh of the arithmetic mean inspection and net hole size.
Inspection of quality of woven wire mesh in production could not exist in the process of manufacturing defects, under normal circumstances, the roll delivery metal mesh.
Do not allow the major defects, allowing a small amount of important defects exist, allow a certain number of defects exist in general.
Major defect category mainly refers to the major defects: warp/weft weaving unstable, with both hands finger rub moves up and down, loose warp/weft wire has obvious displacement phenomenon;
Curly, mesh is greater than or equal to 0.
18 mm, 1 m long net surface natural curl diameter less than 80 mm;
The mesh less than 0.
18 mm, to 1 m long with natural curve surface is less than 60 mm diameter, and should be judged not qualified.
Net oblique, weaving width online face fabric and yarn not vertical greater than 4 degrees;
More than large crease;
Heavy between radial mesh over tolerance;
Super large density difference;
Run large weft, uneven surface;
The warp and weft wire diameter serious error;
Hole, half weft, larger fork;
The serious uneven color of large area, severe mechanical damage.
