How to Clean the Sintered Stainless Steel Mesh Filters

Sintering can be performed on most types of woven wire mesh. The key reason to sinter a wire mesh is to bond all wires where they cross, hence preventing medium migration. As-woven meshes are usually sensitive to edge fraying. A square inch of 100 mesh comprise of 200 wire strands touching at 10,000 contact points, many bond one at a time by any other process. Although, if suitably sintered, virtually each point is secured fused. In fact small discs can be punched from the cloth without fraying. It is critical in various applications like medical filtration or aircraft hydraulic fluid filtration where loose wires causes severe failure. Additionally, mesh shape becomes permanently fixed when the wires are fused in place. Wires cannot be moved under pressure and the aperture size hence remains stable in process.

The sintering process is also a heat treating process. If the process atmosphere and cycle are perfectly controlled, the mesh received is bright and clean, fully ductile and metallurgically solution annealed. Besides the annealing, overall tensile strength is enhanced in most weaves because of bonding between wires. Thermal and electrical conductivity increase. Formabilit and ductility are significantly enhanced, including the potential to keep shapes and retain pleats.

Mesh is not properly sintered if the bonds are weak or if just a small count of intersections are perfectly bonded, or if wires therein fray quickly. Another major purpose and benefit of the sintering process is to develop new structures by laminating numerous layers of wire cloth together in laminates or composites of different varieties. A sintered laminate is a new material, unlike to component layers and the whole becomes more than the total of its components.

Sintered filter can be categorized into sintered mesh filter element, felt filter element and powder filter element. These filters have major applications in the industrial sector. Cleaning of stainless steel sintered mesh filter elements is a crucial process. You need to be prepared before cleaning the sintered stainless steel wire mesh filters.

A fine mesh screen can also be laminated to the surface of an arbitrarily thick and durable strong structure comprising of multiple layers of heavy support mesh screens or to a perforated or expanded metal plate.

Cleaning of Sintered wire mesh filters

Ultrasonic cleaning for cleaning stainless steel sintered wire mesh filter element extends the life of filter elements offering the customer cost savings and in some cases save time. Ultrasonic cleaning involves the use of high frequency sound waves to agitate in a liquid. Cavitation bubbles induced by the agitation act on contaminants adhere to the substrates such as metals, glass, rubber and ceramics. This action enters blind holes, cracks and recesses. The purpose is to fully remove all traces of contamination tightly adhering or embedded on the solid surfaces. Water or other solvents can be used, on the basis of type of contamination and work material. Contaminants include dust, dirt, oil, pigments, rust, grease, algae, fungus, flux agents and mold release agents and others. With ultrasonic cleaning of different range of material shapes, sizes and materials and may not need the component to be disassembled before cleaning.

Cleaning Oven

Baking furnace filter on extreme grease contaminants in the continuous temperature of 380oC. NC ultrasonic cleaning machine. Cleaning tank to heat the filters. Strong cleaning agent, an efficient water based cleaning agent should be used. As the chloride ion causes intergranular corrosion of austenitic stainless steel, therefore the cleaning agent should be free of chloride. Deep water should be taken for cleaning, chloride ion content in water should be below 20mg/L. Gas should be filtering through 5 micro-m dust removal filter system.
