摘　　要：为解决竹材在硫酸盐法蒸煮过程中硅与氢氧化钠反应生成硅酸钠而进入蒸煮黑液,导致碱回收系统一系列的"硅干扰"问题,通过在硫酸蒸煮过程中添加偏铝酸钠、氧化钙、硫酸铝留硅剂和在预苛化过程中添加铝盐除硅剂可降低或解决"硅干扰"对竹浆制浆的影响。To resolve the ＂silicon interference＂ of alkali recovery system caused by silicon reacted with sodium hydroxide forming sodium silicate and into stewing black liquid in bamboo wood stewing process with sulfate, it could reduce or resolve the influence of ＂silicon interference＂ to bamboo pulping by adding precipitated silica agent as so- dium meta -aluminate, calcium oxide, aluminum sulfate in stewing with sulfate process, and adding silicon removal agent as aluminum salt.
