    摘要： A method of manufacture of foamed celluloid molded products, involving three steps for the manufacture of higher density (0.7 to 1.25 gm/cc) foamed celluloid products or simple geometry lower density (0.2 to 0.7 gm/cc) foamed celluloid products, and four steps for the manufacture of lower density foamed celluloid products of any geometry. The three step process involving: (1) providing small, uniform, pieces of celluloid; (2) presoaking the pieces in a physical blowing agent (PBA) under pressure; and (3) foaming at raised temperature a controlled quantity of the presoaked pieces in a mold—to obtain the desired shape and density. For a lower density foamed celluloid product, of any moldable geometry, the steps are to: (1) small pieces of celluloid, that (2) have been presoaked in a PBA, are (3) pre-expanded to an intermediate density, and then (4) foam the desired lower density foamed product in a mold at raised temperature.

    摘要： The present invention relates to a membrane separation method and a relevant equipment, in particular to a method and an equipment for membrane separation utilizing concentration polarization during membrane filtration process, especially, to a concentration process and equipment and a drawer special for drawing a concentration polarization layer. The direct removal of the concentration polarization layer from membrane surface not only decreases the adverse influence of concentration polarization on membrane separation but also obtains concentrated retention components, thereby significantly improving the ability to maintain membrane flux, solving the twinborn problems concerning concentration polarization and membrane fouling during the membrane separation process, and achieving a high-efficiency concentration for retention components. The method and equipment of the present invention can be widely applied in various membrane techniques, in particular in a membrane separation process for concentrating biomacromolecule and organic micromolecule products such as sugars, organic acids and polypeptides etc.
