EFFECT OF HOT-WATER PRE-EXTRACTION ON THE PROPERTIES OF WHEAT STRAW CHEMI-MECHANICAL PULP (CMP)

摘要：

The Chemi-Mechanical pulping properties of wheat straw, which had been hemicelluloses pre-extracted with hot-water, were studied. In this work,the process of hot-water pre-extraction at various temperatures was investigated. The straws pre-extracted or not were made into Chemi-Mechanical Pulp (CMP)at same conditions. Then the effects of pre-extraction on properties of straw pulp were studied. The results show that the hot-water pre-extraction improved tensile strength, tearing strength and bursting strength of the CMP, decreased soda consumption in chemical treatment stage, and reduced energy consumption in the process of beating. However, the pulp yield decreased in various degrees.
