我厂于1980年新建一座可存放55吨盐酸的立式贮池,池体为200毫米厚的钢筋混凝土结构。防蚀层为内衬环氧煤焦油玻璃钢12层,已投产使用近8年,现仍在继续使用中。一、对混凝土基层要求和处理钢筋混凝土脱模后,进行2次抹平,其厚度大于20毫米,干燥后其内部含水率低于6%。表面外观要求坚固密实,不起砂、无起壳、裂缝、麻面等缺陷。阴角做成斜面或园弧过度,平面上的平整度用2米直尺检查高低
In 1980, our factory built a new vertical storage tank capable of storing 55 tons of hydrochloric acid. The tank body is 200 mm thick reinforced concrete structure. Anti-corrosion layer is lined with epoxy coal tar 12 glass fiber reinforced plastic, has been put into operation for nearly 8 years, is still continuing to use. First, the requirements of the concrete base and deal with the demolding of reinforced concrete after 2 smoothing, the thickness of more than 20 mm, after drying its internal moisture content of less than 6%. Surface appearance requirements solid, can not afford sand, no shell, cracks, pitted and other defects. Negative angle made of beveled or park arc over the flatness of the plane with a 2-meter ruler to check the level
