The stainless steel powder filter element is made of high-quality stainless steel powder by high-pressure molding and high-temperature sintering. Through the screening and grading of high-quality raw materials, products with different filtering accuracy of 0.1-100 microns can be achieved. With strict molding, pressing, and sintering welding processes, stainless steel filter elements with high porosity and uniform pore diameter can be obtained. At the same time, they have high strength, good toughness, corrosion resistance, high-temperature resistance, and other properties.
The raw materials of stainless steel powder filter elements are widely selected, such as 316L, 304L, 310S, 321, 904L, etc. At the same time, nickel-based alloys such as Hastelloy, Monel, Inconel, etc. can be used as raw materials to prepare filter elements. Therefore, customers can choose filter elements of different materials according to the actual working conditions.
There are four types of powder filter elements: single-layer filter element (JW-DC), double-layer filter element (JW-SC), coated filter element (JW-TC), and axial pressure filter element (JW-ZY).
Single-layer products (JT-DC) are our conventional products, which can be made into tubular, cylindrical, conical, and other shapes. The products are widely used in chemical, pharmaceutical, environmental protection, metallurgy, food and beverage, petrochemical, and other fields.
The double-layer product (JW-SC) has a double-layer structure. By matching powders with different particle sizes and adopting a one-time molding process, the gradient distribution of pore diameter can be achieved. The double-layer structure plays the role of support and filtration at the same time, and the gradient pore structure has better permeability than conventional products, reducing the differential pressure. Double layer product is a new solution for cross-flow filtration in chemical, pharmaceutical, and other fields.
The coating product (JW-TC) is a high-precision membrane filtration product, which achieves an excellent filtration effect and high permeability. The utility model comprises a filter layer and a support layer, which can obtain products with high adhesion and good mechanical strength after high-temperature sintering. TC products have ultra-fine spherical powder filter layer, and the filtering accuracy can reach 0.1 μ m.
Gold titanium axial compression products (JW - ZY) are usually various small-size discs and tubes. The precision casting mold and precise pressure control can control the dimensional tolerance of products in a smaller range to meet the needs of various customers.
