Research of Physical and Chemical Properties of Powder Cellulose from Various Type of Raw Materials

Abstract:

The features of obtaining powder cellulose from non-woody plant materials, excluding the stages of acid and / or enzymatic hydrolysis using the original technological approach at atmospheric pressure and temperature, were studied 90-100 degree of Celsius. The feedstock after alkaline treatment, according to the proposed technology, is subjected to physico-chemical activation using a modified extrusion unit, providing intensive grinding and defibrillation of the fibers, washing, drying, grinding on a hammer mill. Physicochemical and structural studies of the obtained powder pulp from lucerne, oat straw and cotton powder pulp were carried out. The efficiency and prospects of the proposed process are shown.
