摘　　要：研究了稻草高得率浆通过硼氢化钠预处理过氧化氢漂白工艺过程,发现此漂白方法可以适当提高稻草过氧化氢漂白高得率浆白度,为国内稻草漂白高得率浆生产提高了技术支撑。实验得出最佳漂白工艺为:预处理硼氢化钠用药量3%、处理时间2min,漂白过氧化氢用药量8%,氢氧化钠用药量3%,漂白时间60min,漂白温度85℃。在上述工艺条件下漂白得出的浆料白度为49%ISO,比未预处理过氧化氢漂白白度提高了4%。this experiment is mainly about straw high-yield pulp sodium sorohydride pretreatment beaching. And find it can increase whiteness of the pulp moderately, and provide technical support for production of straw bleached high-yield pulp. Eventually the optimal bleaching process comes that： dosage of pretreated sodium borohydride 3%, time 2 minute, dosage of bleached hydrogen peroxide 8%, dosage of sodium hydroxide 3%, bleaching time 60 minute, temperature 85℃. And the conse- quence comes that the whiteness of straw high-yield pulp add up to 49%ISO, increased by 4G com- pared with traditional hydrogen peroxide bleaching straw high-yield pulp.
