Because stainless steel mesh can block the vast majority of the minimum diameter of solid particles, so stainless steel mesh can be used as a stainless steel filter screen, and the filtration of stainless steel filter screen is to be able to pass the minimum diameter of solid particles. For example, the square - hole stainless steel mesh filtration is its mesh size. The actual value of mesh size directly affects its filtration degree. Nevertheless the filtering degree of stainless steel dense grain filter net has 3 kinds respectively are: nominal filtration degree, absolute filtration degree, actual filtration degree.
Nominal filterability refers to the transverse section of the woven stainless steel dense mesh, the circular diameter of the triangular hole formed by the interweaving of warp and weft.
Absolute filterability: refers to the cross section of the twill braided dense grain network, and the maximum diameter of the internal tangential circle on the inclined surface of the triangular hole formed by the adjacent two weft threads and warp threads.
Actual filtration degree: refers to the filtration degree of the dense grain mesh under actual conditions of use. For a specific specification of the dense stainless steel filter screen, when the conditions of use change, the actual filtration of the dense stainless steel screen with the same specification also changes accordingly. The actual filtration degree of dense mesh is directly affected by the temperature, pressure difference, the length of service time, the viscosity of the medium, the bending times of the filter hole and other service conditions. Therefore, the actual filtration degree is a variable value.
