【摘要】 从综合利用的角度出发 ,对比了AS AQ法落叶松蒸煮废液 (AS L)、NS AQ法杨木蒸煮废液 (NS L)及二者按 1∶4体积比混合而成的废液 (M L) ,与钙盐基酸性亚硫酸盐法木浆蒸煮废液 (Ca L)和亚硫酸氢镁法苇浆蒸煮废液 (Mg L)的组成成分、表面活性、废液粘度等基本性质 ,也对作为粘结剂、木素铁铬盐、水泥减水剂等应用性质进行了比较。与Ca L和Mg L相比 ,AS L、NS L和M L的无机物含量高 2 0 %～30 % ,木素磺酸盐含量较Ca L和Mg L低 2～ 4个百分点 ,废液粘度远低于Ca L和Mg L ,但表面活性高于Ca L和Mg L。将固含量为 50 %的废液直接用作锌矿粉的粘结剂、合成油田钻井用木素铁铬盐及水泥减水剂 ,AS L、NS L和M L的使用效果都相当于或优于Ca L和Mg L。更多还原

【Abstract】 Some basic properties including compositions, surface activity, viscosity and some performances using as adhesive, lignin ferric chromic salt, the water reducer of concrete of the larch AS-AQ pulping waste liquor (AS-L), aspen NS-AQ pulping waster liquor (NA-L), mixed waste liquor (M-L) of AS-L and NS-L (volume ratio 1∶4) are compared with the wood calcium base acidic sulfite pulping waster liquor (Ca-L) and reed magnesium bisulfite pulping waste liquor (Mg-L). Comparing with Ca-L and Mg-L, the inorganic contents of AS-L, NS-L, and M-L are 20%～30% higher, lignosulfonate content is 2～4 percent lower, waste viscosity is much lower, and surface activity is higher. When the water liquor containing 50% solid content are directly used as the adhesive of zinc fine ore, and lignin ferric chromic salt, the results of AS-L, NS-L and M-L are similar or superior to Ca-L and Mg-L.更多还原
