Wheat Straw Pulp, Preparation Method Therefor, Application Thereof and Method for Adjusting Degree of Substitution of CMC

Abstract

A wheat straw pulp, a preparation method therefor, an application thereof, and a method for adjusting the degree of substitution of CMC. The preparation method for the wheat straw pulp comprises the following steps: using water as a medium, performing ultrasonic crushing on wheat straw, performing solid-liquid separation, and collecting the solid to obtain wheat straw pulp, the temperature of the ultrasonic crushing being 25-100° C. In the preparation method, by using water as a medium, wheat straw is dissociated into wheat straw fibers in water in a mild temperature condition by means of ultrasonic crushing accompanied by H2O2. The wheat straw pulp can be used for preparing CMC. By adjusting different technological conditions to adjust the properties of the wheat straw pulp, CMC having different degrees of substitution can be prepared.
