Filter module systems can be used for waste water treatment, manufacturing of mineral pigments, recovery of fibers, dewatering of ceramic bulk, filtration of metallic salt solutions, coal and ore from flotation processes, separation of oil and so on Support tray materials are wood, metal and rubber. These elements are showing a lot of disadvantages as for example corrosion resistance and bad sealing. However Polypropylene(PP) turned out to be the best material due to it's most favourable price-power-performance and its interesting combination of excellent properties. Herein, different amounts of the chopped glassfiber and silane treated silica were incorporated in PP for filter recess and filter base. Thermoplastic polyurethane(TPU) was employed as filter membrane. Their parts were also thoroughly investigated in terms of tensile properties, flexural properties, durability against dynamic mechanical movement, thermal stability and so on. |
