摘　　要：对中性亚硫酸钠-蒽醌法杨木蒸煮废液(NS-L)和碱性亚硫酸钠-蒽醌法落叶松蒸煮废液(AS-L)做锌矿粉的成型粘合剂进行了研究。并与二者的混合液(体积比4∶1)(M-L)、酸性亚硫酸盐法木浆废液(Ca-L)及亚硫酸氢镁法苇浆废液(Mg-L)的粘结效果进行了比较。NS-L的适宜工艺条件是:干燥温度165℃;干燥时间15 min;物料配比为锌矿粉、废液用量、水的质量比为75∶5∶1,抗拉强度可达1.732 MPa。AS-L的适宜工艺条件是:干燥温度175℃,其余同NS-L,抗拉强度可达1.656 MPa。在各自的适宜工艺条件下,取相同的废液用量(浓度约50%的废液用量5%,对矿粉),NS-L具有最好的粘结效果;其次是AS-L、Mg-L和M-L,这三者的粘结效果相近;Ca-L的粘结效果最差。Aspen neutral sulfite-unthraquinone pulping waste liquor （NS-L） and Larch alkaline sulfite-anthraquinone pulping waste liquor （AS-L） axe used as the adhesive for the forming of zinc ore powder. Their adhesive effects are compared with that of the blended waste liquor of NS-L and AS-L （volume ratio 4：1）（M-L）, the wood acidic sulfite pulping waste liquor （Ca-L） and reed magnesium bisulphite pulping waste liquor （Mg-L）. The optimum application conditions of NS-L used as the adhesive of zinc ore powder are that drying temperature 165℃ ; drying time 15 min; the mass ratio of zinc fine ore： waste liquor： water= 75：5：1. The tensile strength reaches 1.732MPa under these conditions. The optimum conditions of AS-L are the same as NS-L except that the drying temperature is 175℃, the tensile strength reaches 1.656MPa. NS-L has the best adhesive effect, the followings are AS-L, Mg-L and M-L which have the similar adhesive results. Ca-L has the worst adhesive effect among these waste liquor when the comparison is made on the same application dosage and under respective optimal application conditions.
