江西宜春专区几年来修建了不少中小型抽水机贮油罐工程,但漏油的情况较多。经过各地不断摸索研究找到了二个防止油罐漏油的经验,使用效果良好,特介绍供参考。(一)混凝土中加掺合料法:混凝土贮油罐发生渗漏的主要原因是油容易从开口微孔渗入混凝土中,再沿毛细管逐渐饱和渗出罐外,挥发流失。解决的办法,可在混凝土中均匀地加入占水泥重量3%的胶状氢氧化铁,填堵混凝土内的毛细孔,使用效果良好。其配制方法是将三氯化铁和烧硷放入缸中,加水搅拌
Yichun Prefecture in Jiangxi Province in recent years to build a lot of small and medium sized pump storage tank project, but more oil spills. After continuous exploration around the study found two oil tank to prevent oil leakage, the use of good results, special introduction for reference. (A) Addition of concrete admixture method: Concrete tank leakage occurs mainly because oil easily penetrate into the open pores of concrete, and then gradually saturated capillary out of the tank, volatile loss. The solution can be evenly added to the concrete, accounting for 3% of the weight of cement colloidal iron hydroxide, fill the concrete pores, the use of good results. The preparation method is to put ferric chloride and caustic soda into the cylinder, add water and stir
