How big is the aperture of the screen of 1 mesh and 2 mesh

1 mesh is, 2 mesh is. The number of mesh mesh refers to the length of one inch, and how many holes are arranged in total, that is, how many meshes. The screen type is a representation of the screen printing plate in terms of the number of mesh and the diameter of the mesh.

In other words, the mesh size and strength of the screen are the main indicators to measure whether it is suitable for printing or not. The diameter of the mesh is thick, and the screen is strong, so it is durable. The reasonable mesh size makes the printed screen itself provide a reasonable amount of pulp and is placed on the surface of the fabric, and the selection of a reasonable screen mesh mesh also provides a basis for the reasonable mesh size.

The 20 mesh mesh aperture is the mesh screen, which refers to the fact that there are 20 holes in the length of 1 inch, and the 20 mesh means that there are 20 holes in the length of one inch.

The mesh is the number of holes per square inch of 20 meshes and 20 holes per square inch.

1 square inch = square millimeter.

square millimeters. > example, a 400-mesh screen has a pore size of about 38 microns, and a 500-mesh screen has a pore size of about 30 microns. Because there is a problem with the opening ratio, that is, because of the difference in the thickness of the silk used in weaving the net.

The standards of different countries are also different, and there are three kinds of standards in the United States, British standards and Japanese standards, among which the United Kingdom and the United States are similar, and the Japanese standards are quite different. Our country uses American standards. The specific specifications of the national standards vary, but the sieve system is generally proportional.

The mesh size of the 100 mesh screen is:

"mesh" or "mesh" is the number of mesh holes per square inch (1 inch wide. For example, 50 mesh means that there are 50 eyelets per square inch.

The larger the mesh number and the more holes, the finer the particle size and the smaller the particle size of the material; The smaller the mesh number and the fewer the holes, the larger the particle size and the larger the particle size.

Each country has a standard screen number specification, and the allowable deviation of the screen hole size corresponding to each screen number in the specification is limited.

The 30 mesh screen is mainly the braided wire diameter of the wire diameter of the use range, although the 30 mesh in the screen is the number of meshes, but not the size of the mesh, it can be seen that the number of meshes in the same range is the same data, the thickness of the wire is the main factor that directly affects the size of the screen mesh.

The 30 mesh mesh is mainly to see that there are 30 groups of mesh and wire diameter synthesis within the range, so divide by 30 is a group of synthesis (wire diameter plus pore diameter) for the mesh is, and the wire diameter mesh is the hole.

Mesh holes are holes. It can be seen that the coarser the filament, the smaller the pores, the number of pores is fixed, and the size of the mesh is the thickness of the wire diameter.

160 mesh refers to 160 holes in one square inch, then each inch length is the hole, and the diameter of each hole is 2 mm.

Definition of particle mesh: the larger the mesh, the finer the particle size of the material; The smaller the mesh, the larger the particle size of the material. The sieving particle size is the size of the mesh that the particles can pass through the screen, 1 square inch (the number of mesh holes in the area is called the mesh).

The specifications of standard screens vary from country to country, and the commonly used Taylor system is based on the number of holes per inch of length as the screen number, which is called mesh. For example, a 100-mesh sieve means that there are 100 mesh holes per inch of screen.

A plus or minus sign before the mesh indicates whether the mesh of the mesh can be missed. A negative number indicates that the mesh can be leaked through that mesh, that is, the particle size is less than the mesh size; A positive number indicates that the mesh cannot be missed, i.e., the particle size is larger than the mesh size.

For example, the particles are -100 mesh + 200 mesh, that is, these particles can leak from the 100 mesh but can not leak from the 200 mesh mesh, when screening the particles of this mesh, the large mesh (200) should be placed under the screen of the small mesh (100), and the screen left in the large mesh (200) is -100 + 200 mesh particles.

The screen has the American Taylor standard screen and the current standard screen in China, and the 160 mesh screen is about 95um=.

Let's give you a comparison table for reference.
