Metal sintered felt is also known as sintered felt, stainless steel sintered felt, precision filter sintered felt, micron filter sintered felt, metal fiber sintered felt, sintered metal fiber felt;
Types of metal sintered felts: sintered felts without mesh, sintered felts with mesh, and coated felts;
Metal sintered felt material: 304, 316, 316L, 310S, 00cr2AL6, iron-chromium-aluminum, titanium alloy, Hastelloy, nickel-based alloy, etc.
Standards for metal sintered felt products
1. The determination of filtration accuracy and dirt-holding capacity shall be carried out in accordance with the provisions of GB/T18853-2002.
2. The bubble point pressure is measured according to the regulations in GB/T5249.
3. The air permeability is measured according to the regulations in GB/T5453, the pressure difference is 200Pa, and the medium is air.
4. The breaking strength is measured according to the regulations in GB/T228.
Metal sintered felt is made of metal fibers with a diameter of micron, which are non-woven, laminated and sintered at high temperature. It can continuously maintain the filtering effect of the filter cloth, and has the characteristics of three-dimensional network, porous structure, high porosity, large surface area, and uniform pore size distribution.
