SG-2化学浆液是一种用水玻璃作主剂,用两种低分子有机化合物作胶凝剂的注浆材料。三者均为液体,原料来源广泛。一般在使用前配制,随配随用,配法简单,使用方便。配制的SG-2浆液粘度,常温下4～8cP。其渗透性能好,浇于松散的细砂上,能自由向下渗透。固砂试块耐久稳定,室内试验将固砂体及纯胶体在稀硫酸、稀氢氧化钠和清水养护2年多,未见变质。原料中无毒性污染物。可用单液法、双液法或双单液结合注浆法施工。1989年12月,SG-2浆液首次试用于湖南龙山金锑矿800炸药总库的堵漏防渗工程中,对五个炸药库注浆封堵导水管中涌水,并通过导水孔向药库壁后注浆,封堵微细渗水裂隙。固砂强度达1.9～2.3MPa。
SG-2 chemical slurry is a water glass as the main agent, two kinds of low molecular weight organic compounds as a gelling agent grouting material. Three are liquid, a wide range of sources of raw materials. Generally formulated before use, with the accompanying use, with a simple method, easy to use. Preparation of SG-2 slurry viscosity, room temperature 4 ~ 8cP. Its permeability is good, poured in loose sand, free to infiltrate. Solid sand test block durable and stable, indoor test solid sand body and pure gel in dilute sulfuric acid, dilute sodium hydroxide and water conservation more than 2 years, no deterioration. Raw materials non-toxic pollutants. Available single-liquid method, double-liquid method or double single-liquid grouting method construction. December 1989, SG-2 slurry for the first time in Hunan Longshan gold antimony 800 explosives the total reservoir plugging seepage control project, the five explosives reservoir grouting plug gutter gushing water, and through the aqueduct to the medicine After the wall grouting, sealing micro-seepage cracks. Sand strength of 1.9 ~ 2.3MPa.
