What is the filtration degree of stainless steel woven wire mesh?

When stainless steel wire mesh is used as a stainless steel filter, it can block the minimum diameter size of most solid particles, which is called the filtration degree of the stainless steel filter.
The filtration degree of square hole stainless steel wire mesh is its mesh size. The actual value of the mesh size directly affects its filtration degree.
There are three types of filtration degrees for stainless steel dense mesh: nominal filtration degree, absolute filtration degree, and actual filtration degree.
Nominal filtration degree (also called nominal aperture): refers to the cross-section of the woven stainless steel dense mesh, the inscribed circle diameter of the triangular hole composed of warp and weft interweaving.
Absolute filtration degree (also called absolute aperture): refers to the cross-section of the twill woven dense mesh, the maximum inscribed circle diameter on the inclined surface of the triangular hole composed of two adjacent wefts and warp wires.
Actual filtration degree: refers to the filtration degree of the dense mesh under actual use conditions. For a specific specification of dense stainless steel filter, when the use conditions change, the actual filtration degree of the dense stainless steel wire mesh of the same specification will also change accordingly. The actual filtration degree of the dense mesh is directly affected by the use conditions such as temperature, pressure difference, length of use, viscosity of the medium, number of bending times of the filter holes, etc. Therefore, the actual filtration degree is a variable value.
