After the professional data query, it is found that the stainless steel screen or the stainless steel mesh is the mesh with the plus or minus sign indicating whether the mesh can be missed. The negative number indicates the mesh that can leak the mesh, that is, the particle size is smaller than The mesh size; the positive number indicates the mesh that cannot be missed, that is, the particle size is larger than the mesh size. For example, the particles are -100 mesh to +200 mesh, which means that the particles can leak from the 100 mesh mesh. It cannot be leaked from the mesh of 200 mesh. When screening the particles of this mesh number, the large number (200) should be placed under the mesh with a small mesh size (100), and the mesh size is large (200). What is left in the screen is the -100~+200 mesh particles. So what is the difference between the stainless steel screen 10 mesh and the 14 mesh stainless steel mesh? How to explain it?
Different materials:
316 contains more than 304 nickel, and nickel is an important component affecting the anti-rust properties of stainless steel.
From the eye point of view, the two are no different, but the service life will be different in the process of use. Nickel-free stainless steel is rusted after being wet or wet, and nickel-containing screens have a relatively long service life.
Compared with the 304 stainless steel screen, the main difference between the chemical composition of 316 and 304 is that 316 contains mo, so 316 will have strong corrosion and rust resistance.
Therefore, when selecting a stainless steel screen, if the corrosive material is filtered, it is more suitable to select a 316 stainless steel screen. This is also essential to consider. Whether you are filtering or sieving or doing it for other purposes, it's a mess.
