Abstract:
Composite members and methods for forming composite members are provided. A composite member includes a base member, the base member formed from a polyethylene. The composite member further includes a tape bonded to the base member. The tape is formed from a fiber reinforced thermoplastic material. The fiber reinforced thermoplastic material includes a plurality of fibers dispersed in a polyethylene resin. A method includes forming a base member from a polyethylene material. The method further includes bonding a tape to the base member. The tape is formed from a fiber reinforced thermoplastic material. The fiber reinforced thermoplastic material includes a plurality of fibers dispersed in a thermoplastic resin.
Abstract:
A process for the aeration of wastewater employs an aerator comprising a porous body having an average pore size from 5 to 250 μm produced by sintering a composition comprising polyethylene particles having a molecular weight of at least 3×105 g/mol as determined by ASTM-D 4020 and a weight average particle size, D50, from 20 to 650 μm. The porous aerator is provided in the wastewater and an oxygen-containing gas, such as air, is passed through the porous aerator into the wastewater to assist in purification of the wastewater.
