It can be used in the process of refining and chemical production, and the separation and recovery of intermediate products, liquid purification, tape, CD. And the purification of photographic film in manufacturing, oilfield injection well water and gas removal particle filtration. However, the stainless steel sintered metal filter element with such a large effect is also used in life. After the filter element is used, it should be cleaned relatively cleanly.
 
The following describes the cleaning method of stainless steel sintered metal filter;
 
1. When there are dust and dirt on the surface, it can be washed with soap, weak detergent or warm water.
 
2. The trademark and film of the surface stainless steel filter cylinder are washed with warm water and weak detergent. The binder component is scrubbed with alcohol or organic solvent (ether, benzene).
