How to identify the quality of stainless steel filter mesh?
The common acid-base stainless steel filter mesh is mainly used for screening and filtration under acid and alkaline conditions, and separation of gases, liquids and other media. Stainless steel mesh generally uses stainless steel mesh, nickel wire and copper wire as raw materials. The woven wire mesh is densely arranged in the weft thread, and the stainless steel mesh is woven with plain weave, twill weave, mat weave, and herringbone weave. Stainless steel mesh size 5 mesh - 630 mesh. Stainless steel mesh has the characteristics of stable filtration and fineness. Can also be designed and manufactured according to user needs of various types of stainless steel mesh products.
Stainless steel filter is widely used.Stainless steel filter screen is used for screening and filtration under acid and alkaline conditions, oil industry is used for mud network, chemical fiber industry, and sieve filter and electroplating industry is used for pickling.Also used in mining, petroleum, chemical, food, medicine, machinery manufacturing and other industries.
Stainless steel filter features
1. The filtering effect is very stable: During the production process, high-quality raw materials are selected so that they are not easily deformed during use.
2. High strength: High-quality materials have high pressure resistance and can withstand greater work strength.
3. Easy to clean: The single-layer filter material has the characteristics of simple cleaning, especially for backwashing.
4. With high temperature performance: the highest temperature can withstand about 480 °C.
5. Corrosion resistance: Stainless steel raw material itself has high corrosion resistance and wear resistance.
6. Easy to process: High-quality materials can be well-processed regardless of cutting, bending, stretching, and welding.
Identify the quality of stainless steel filter mesh:
1. The interweaving between the warp and weft threads of the net is not robust and tight. When the fingers are moved up and down several times, the warp and weft threads will have apparent loose displacement.
2. Stainless steel filters open up in the future and appear as serious roll-ups. In addition, if the mesh standard is greater than or equal to 0.18mm, the natural tortuous diameter of a stainless steel filter mesh with a length of 1m is less than 80cm, and the mesh standard is less than 0.18mm, a stainless steel filter mesh with a length of 1m with a natural meander diameter of less than 60mm shall be regarded Failed.
3. The network is severely skewed, and after professional measurement, the latitude and longitude of stainless steel filters are not straighter than 4 degrees.
4. In the inspection process, there is a large area of creases on the surface of the mesh, and these creases should also be judged to be unqualified when they cannot be restored to the flat condition after passing through the wire mesh and pressure countermeasures.
5. If there is a large mesh hole difference between the longitudes, it should be regarded as unqualified.
6. Large area density is poor.
7. Check if the net surface is uneven or not. If you look closely, see if there is a large-faced appearance of running and weft.
8. The diameter of the warp and weft threads exceeds the allowable plan.
If the stainless steel filter mesh you buy is a substandard product, the process is not up to standard.The contents of metallic chromium and other additives are insufficient, and no solution treatment has been performed. Alloy elements have not dissolved into the matrix.This results in low matrix alloy content and poor corrosion resistance.This substandard stainless steel filter mesh will easily rust.
