After repeated cleaning, the filtration performance can be recovered to more than 90%. The structure is stable and not easy to deform.
In addition, the size of the filter element can be adjusted according to the needs. Accurate filtration performance, suitable for high and low temperature environment.
The filter element of sintering screen is a kind of commonly used filter material. In the stainless steel sintering net, it is made of special laminated plates with high overall rigidity and mechanical strength. At the same time, sintered filter element is also a good filter material, and its comprehensive performance is obviously better than other similar products.
It has a good filtering mechanism in the sintering screen filter element. When the filter cake is mechanically filtered, many inclusions larger than the mesh size of the sintering screen filter element are blocked at the entrance of the sintering screen filter element.
With the increase of the number of closed inclusions, a "filter cake" composed of large inclusions is formed on the inlet surface of the sintering screen filter element. The filter cake thins the flow, and the inclusions smaller than the mesh size of the sintered mesh filter element are also partially captured on the "filter cake".
Adsorption mechanism: the filter element of sintering net has a large specific surface area. The liquid metal flow is divided into fine flow units through the stainless steel sintering net, which increases the contact area between the metal melt and the filter medium, the harmful elements and oxidation in the molten metal.
The complex physical and chemical reactions with the surface of the filter element are adsorbed on the surface of the filter, making the inclusions adhere to the filter frame layer by layer.
