High mesh Stainless steel mesh
High meshStainless steel mesh has small mesh, medium mesh and high mesh number in specifications (general mesh is higher than 300 mesh and belongs to stainless steel mesh with high mesh number). In our use process, it cannot be seen clearly with the nHigh mesh Stainless steel mesh has small mesh, medium mesh and high mesh number in specifications (general mesh is higher than 300 mesh and belongs to stainless steel mesh with high mesh number). In our use process, it cannot be seen clearly with the naked eye, and its surface is woven With regard to the method and surface structure, manufacturers of stainless steel nets generally use 40-fold microscopes and 80-fold microscope observations.
When the high mesh stainless steel mesh tests its standard, it is generally pided into two methods:
First, the macro-inspection: the use of the naked eye or 10 times the following low-magnifying glass to observe the stainless steel mesh material internal structure and defect inspection. Frequently used methods include fracture inspections, low magnification inspections, tower-shaped turning hairline inspections, and sulfur experiments. The macroscopic inspection of stainless steel mesh mainly includes some defects such as air bubbles, slag inclusions, delamination, coarse cracks, white spots, segregation, and looseness.
Second, the microscopic examination: now also called inspection for high-power inspection, is to prepare a good stainless steel mesh type, according to the provisions of the magnification under the microscope entry observation and determination to check the stainless steel mesh material structure and defect inspection methods. General inspection of inclusions, grain size, depth of decarburization layer, intergranular corrosion, etc. The stainless steel mesh was observed under the 80x microscope of British Type 2011jdh-a, and the carbon content and nickel content of the stainless steel mesh material can be detected in both mesh and silk.
The stainless steel mesh mesh number is used for screening and filtration under acid and alkali environmental conditions, the oil industry is used for the mud net, the chemical fiber industry for the sieve filter, and the electroplating industry for the pickling network. Stainless steel high mesh network must be checked before application, in order to better put into use.
