Industry polymer melt filter element is a kind of pleated wire mesh candle filter made of stainless steel (304, 316L) or other metal woven cloth after spot welding, pleating and pressing.Industry polymer melt filter element can effectively remove impurities such as gels and other solid permeates from polymer melts in chemical fibers, textile and plastic industries.
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.
