铬木素化学注浆堵水材料是以亚硫酸盐纸浆废液、重铬酸钠及促凝剂所组成的化学注浆堵水材料。这种材料优点很多:来源丰富,价格便宜,凝胶时间可以控制,凝胶体不溶于水,化学性能比较稳定,浸水膨胀,抗渗性好,因而有利于注浆堵水;施工中不需要特殊设备,既可双液注浆,也可单液 Chromium lignin chemical grouting water blocking material is sulfite pulp waste, sodium dichromate and accelerator consisting of chemical grouting water blocking material. This material has many advantages: rich source, cheap price, gel time can be controlled, the gel is insoluble in water, chemical stability is relatively stable, flooding expansion, good impermeability, which is conducive to grouting water; construction does not require Special equipment, both double-liquid grouting, but also a single solution
