CELLULOSE NITRATE STABILIZATION PROCESS LINE Russian patent published in 1999 - IPC

Abstract RU 2140424 C1

FIELD: cellulose derivative materials. SUBSTANCE: invention relates to production of cellulose nitrates and can find use when preparing cellulose nitrates for production of gun powders, varnishes and dyes, special films, and other consumer's goods. In process line, process solution preparation jet mixers are installed before hot-washing tub and washers. Agitator is directly connected to first-step disintegrating machine, in particular, labyrinth- conical mill. Washers are interconnected over above-said mill. Cellulose nitrate is disintegrated in two steps. EFFECT: accelerated process and enabled preparation of size-uniform cellulose nitrate particles. 2 dwg, 1 tbl
