IMPROVEMENTS RELATING TO PLASTICS ARTICLES |
摘要 |
A pellet formed from a mix of two polymer materials which are non-homogenous is extruded through a die to form a highly roughened surface creating an enhanced melt fracture appearance. The extrusion is chopped into pellet form to provide a large surface area pellet to be used as a harbour for biomass in water treatment processes. Large quantities of such pellets in a filter provide a very effective filtration effect, largely because the highly roughened surface provides an enormous number of cavities within which the biomass can be retained. |
