    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: Particle coating processes and systems employ UV curable materials to form tack-free surfaces rapidly. By applying UV curable compositions on well suspended particles a UV particle coating technology enables a scalable process of coating fine particles at desirable coating thicknesses with a wide spectrum of obtainable properties. Processes in accordance with the present invention decouple the particle suspension and film formation steps, enabling ample time to first deliver evenly the coating materials to the particle surfaces, followed by rapid polymerization/curing reaction induced by the UV light to rapidly create tack-free surfaces, thus preventing particles agglomeration while achieving uniform and thin-layer coating.
