对土(岩)层堵水、加固的注浆材料,通常有水泥浆和化学浆。目前化学浆材中,铬木素浆材是一种颇有前途的材料,但其原料重铬酸钠和木素磺酸盐在凝胶化过程中,或形成固砂体后,会被地下水浸泡出剩余的有毒铬离子,从而污染地下水源。1976年我们曾研究出一种低毒铬木素配方,但是还需要用原配方一半左右的铬盐量,没有根除毒性。我们从研究木素磺酸盐与强氧化剂的反应机理学说出发,在有关厂矿和科研单位的启发和支持下,经过多次试验,制成了完全不要重铬酸钠的一种无毒木素浆材——硫木素。
Soil (rock) water blocking, reinforcement grouting material, usually with slurry and chemical pulp. Currently, chemical pulp, chromium lignin pulp is a promising material, but its raw material sodium dichromate and lignin sulfonate in the gelation process, or the formation of sand body, will be groundwater Soak the remaining toxic chromium ions, polluting groundwater sources. In 1976, we developed a low toxic chrome lignin formula, but we also need about half the amount of chromium salt in the original formula, not to eradicate the toxicity. Based on the study of the reaction mechanism theory of lignosulfonates and strong oxidants, under the inspiration and support of relevant factories and mines and scientific research institutes, after many trials, we made a non-toxic wood that does not need sodium dichromate at all Pulp - thiokiol.
