The process includes suspending the fibres e.g. of asbestos, in an aqueous suspension and applying an organic binder such as polyisobutylene, polyvinylchloride or acrylonitrile/butadiene/styrene. The major part of the water is then removed to form a moist sheet which is pressed and dried to form a separator. The separator is then wetted with a solvent such trichloroethane, cyclohexane or dichloroethylene, although many hydrocarbon based solvents may be used. The solvent is removed, usually by allowing it to evaporate. |
