Stainless steel sintered felt is also called metal sintered felt, metal fiber felt, sintered felt, It is made of extremely fine stainless steel metal fiber (accurate to micron in diameter) which is made by non-woven layering and superimposed by high temperature sintering. Due to the above structure and features, made of stainless steel sintering felt can effectively make up the metal net ease plugging, vulnerable weakness, and can make up for the shortage of the powder filter product, such as fragility and small flow rate, It has the characteristics of temperature and pressure resistance that ordinary filter paper and filter cloth cannot match. Therefore, stainless steel sintered felt is an ideal filter material for high temperature, corrosion and high precision.
Features of stainless steel sintered fiber felt
High temperature and corrosion resistance. Can be used in 480 ℃ environment medium for a long time.
Easy to process, shape and weld.
High dirt holding capacity.
High porosity and excellent permeability.
High stain resistance capacity.
Long replacement cycle;
Little pressure loss and large flow.
Can be welded and machined because of its large filter area.
Easy to clean and can be used for a longer time.
Can produce reinforced, thickened, protected and other specifications according to user's requirement.
Application Fields
Polymer filtration and polyester melt purification.
Filtration of refining process, pre-filtration of ultrafilter.
