Today we take a look at the calculation of the cloth is how to calculate the number of mesh, mesh, is the number of holes, is the number of holes per square inch.
The cloth mesh is greater, the smaller the aperture. In general, aperture of the mesh filter cloth cloth x = 15000. For example, the mesh size of the screen mesh of 400 mesh filter cloth is about 38 microns; the aperture of the screen mesh of the 500 mesh filter cloth is about 30 microns. Because of the opening rate, it is because of braid with wire thickness is different in different countries are not the same as the standard, the existing American Standard, British standard and Japanese standard of three, the United Kingdom and the United States are similar, the difference of japan. Our country uses American standards, and the above formulas are also calculated according to American standards.
