How to identify the quality of stainless steel filter mesh:

The stainless steel filter mesh is mainly made of 304, 304L, 316, 316L stainless steel punching mesh, stainless steel woven mesh, stainless steel welded wire mesh and other materials. It has the characteristics of acid resistance, alkali resistance, high temperature resistance, tensile strength and wear resistance. It is used for screening and filtration under acid and alkali environmental conditions, as a mud net in the petroleum industry, as a sieve filter in the chemical fiber industry, and as a pickling net in the electroplating industry.

Identification can begin with:

1. The interweaving between the warp and weft of the net is not strong and not tight. With the fingers up and down, the warp and weft will have obvious appearance of loose shift.

2. The stainless steel filter screen will appear in the future and there will be serious signs of rolling. In addition, if the mesh standard is greater than or equal to 0.18mm, the natural zigzag diameter of the stainless steel filter mesh with a length of 1m is less than 80cm, the mesh standard is less than 0.18mm, and the natural zigzag diameter of the stainless steel filter mesh with a length of 1m is less than 60mm. Not qualified.

3. the net slope is serious, and after measuring by professional things, the latitude and longitude of the stainless steel filter net is not more than 4 degrees.

4. During the inspection process, there are large-area creases on the mesh surface. These creases should not be returned to the leveling condition after the stenciling, pressing, etc., and should be judged as unqualified.

5. If there is a large mesh gap between the meridians, it should be considered as unqualified.

6, the large area density is out of tolerance.

7. Check whether the mesh surface is uneven. If you look closely, is there a large-scale appearance of running latitude?

8. The wire diameter of the warp and weft wire is outside the allowable plan.
