摘要:
A filter includes a porous molding, the porous molding being a sintered product of mixed powder containing dry gel powder including an ion exchange resin and thermoplastic resin powder, or a swelled body of the sintered product. When water having an electric resistivity value of 18 MΩ・cm or more is allowed to pass through a space velocity of 1200 hr-1, the electric resistivity value of water after passage is 15 MΩ・cm or more. To provide a filter that can efficiently remove metal ions in a solution to be treated, and easily acquire a solution having an extremely low content of metal ions.
摘要:
A polyethylene powder is described having a molecular weight in the range of from 3,000,000 g/mol to less than 4,000,000 g/mol as determined by ASTM 4020 and a bulk density of 0.10 to 0.20 g/cm3. On sintering, the polyethylene powder produces a porous article having an elastic modulus of at least 90 MPa.
