Silk Screen Mesh Mesh to determine

In plain language to explain, head, is to measure the size of the unit, the greater the mesh shows the smaller particles, the smaller the mesh shows the larger particles, such as 60 mesh particles smaller than 40 mesh, usually to 80 mesh when the time has been Very fine. A friend who has studied analytical chemistry can find some specific explanations on the sieve from the first two or three chapters of the textbook (presumably based on different types and quantities of substances, which are calculated by a certain formula and require the size of the substance, Sieve filter, pick the size of the material particles)

  200 mesh = 74um = 0.074 mm

  80 Mesh = 178um = 0.178mm

  1. Mesh refers to the number of empty eyes per square inch of the screen, 50 means that per square inch perforation is 50, 500 is 500, the higher the number of eyes, the more holes. In addition to representing the perforations of the screen, it is also used to indicate the particle size of the particles that can pass through the screen. The higher the mesh number, the smaller the particle size.

  2. Powder particle size, said particle size. Due to the complex shape of the particles, there are usually several methods, such as sieving size, settling size, equivalent volume size and equivalent surface area size. Screening granularity is that the particles can pass through the Silk  screen mesh size, to 1 inch (25.4mm) width of the Silk  screen mesh sieve number, which is called "mesh." At present, at home and abroad have not yet had a uniform technical standards for grain size, all companies have their own definition and representation of the granularity index. In different countries, different sectors of the screen specifications have different standards, so the meaning of "mesh" is also difficult to unify.

  At present, the international comparison of the equivalent diameter of the particles with a calculated diameter to represent the particle size. Expressed in μm or mm.

  The following table is commonly used Silk Screen mesh size and size (μm) control table.
