Polymer sintered filter is made of 316L stainless steel, iron, chromium, aluminum and other metal fibers with a diameter of micro rating by sintering in high temperature and welding after special non-woven laying and stacking. So, it can withstand the high temperature conditions required in polymer melt filtration process. The sintered filter media has high porosity and delivers low pressure drop, high permeability and great dirt holding capacity.
Polymer sintered filter consists of a protection layer, a filtration layer and a support layer. The protection layer and the support layer are made of stainless steel wire mesh to protect and support the filtration layer. The filtration layer is made of sintered felt and plays a major role in filtering. Sintered felt can be pleated to increase its filter area and enhance its dirt holding capacity, thus improving its filtration efficiency.
We can also offer polymer sintered filters made of Hastelloy, Monel and other alloys for you to choose from.
The filtration system adopts one filter for filtering and one stand-by filter operation mode to achieve continuous, uninterrupted filtration process. First, the polymer melt enters into the filter from the bottom and flows from outside to inside. Impurities are trapped on the filter surface and clean melt flows from the filter inside to the clean melt pipeline at the top of the filter, and then flows out of the filter. When the differential pressure reaches the preset value, the filter filtration efficiency slows down, and the control system will convey the melt to another filter. At the same time, the filter for filtering is replaced and washed.
Polymer melt filter elements work under high temperature and high pressure conditions, therefore, they are mostly connected by thread (M20, M30, BSPP, NPT, etc.), flange, snap coupling, rod connection, etc.
