In practical use, the various characteristics of stainless steel sintered filter elements are mutually restrictive, such as an increase in resistance when the flow rate is high; High filtration efficiency often comes with drawbacks such as rapid resistance increase and short service life.
The stainless steel sintered filter element is mainly made of stainless steel fiber sintered felt and stainless steel woven mesh processed by the bending process. The stainless steel fiber sintered felt can be made into a multi-layer structure with a pore size ranging from coarse to fine, and has characteristics such as high porosity and high pollution absorption capacity; Stainless steel woven mesh is made of stainless steel wires with different diameters, and the filter element made of it has the characteristics of good strength, not easy to fall off, easy cleaning, high temperature resistance, and economical use.
How to choose stainless steel sintered mesh and sintered felt?
1. Material
The material of sintered mesh is the same or multiple types of stainless steel metal woven mesh, while the material of sintered felt is metal fibers with different wire diameters.
2. Aintering process
Although both are named after sintering, their processes are different. Firstly, the sintering temperature is determined. The sintering mesh is produced at 1260 ℃, while the sintering felt is produced at 1180 ℃. The following is the structural diagram of the sintered mesh. It can be clearly seen from the diagram that the sintered mesh is an ordered stacking of stainless steel metal sintered mesh according to the number of layers, while the sintered felt is structurally disorderly disordered.
3. Bina pollution amount
Due to the differences in material and structure, sintered felt will have multiple gradient pore size layers during the production process, resulting in a larger amount of pollutant absorption.
4. cleaning cycle
Under the same cleaning conditions, the cleaning cycle of both is determined by the amount of dirt they contain. Therefore, the cleaning cycle of stainless steel sintered mesh is shorter.
5. blind hole rate
The above process introduction is sufficient to indicate that there are basically no blind holes in stainless steel sintered mesh, while sintered felt may have more or less blind holes.
6. filtering accuracy
The filtration accuracy of stainless steel sintered mesh is 1-300 μ m. And the sintered felt is 5-80 μ M.
