摘　　要：在不同温度条件下,对麦草制浆前进行热水预抽提处理,然后制备化学机械浆,探讨热水预抽提对麦草化机浆浆料性能的影响。研究结果表明:麦草经过热水预抽提后,其化机浆的抗张强度、撕裂度和耐破度均有所提高,碱浸渍段用碱量降低,打浆能耗降低,但纸浆得率有不同程度的下降。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 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 showed 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.
