在化工、冶金、轻工等生产中,均设置有较多数量的贮槽,用来贮存或处理酸、碱介质。过去,这些贮槽常常是采用钢材、铅板及不锈钢板等金属材料制作,但使用寿命不长,损坏厉害。也有用陶质酸坛小量灌装贮存,但占用场地庞大,侵蚀性气体扩散严重,近年来,上海地区在应用非金属材料来建造耐腐蚀贮槽方面做了一些工作。上海染化九厂已较多地采用了水玻璃耐酸混凝土整体式盐酸贮槽,节约了大量钢材和有色金属,经过一年多时间的实际考验,效果良好、上海第四制药厂两年来在该厂施工、使用了砖、混凝土贴衬玻璃钢的
In the chemical industry, metallurgy, light industry and other production, are equipped with a larger number of storage tanks, used to store or handle acid and alkali media. In the past, these tanks were often made of steel, lead plate and stainless steel plate and other metal materials, but the service life is not long, badly damaged. There is also a small amount of pottery used to fill ceramic storage, but occupy a huge site, the spread of aggressive gases, in recent years, Shanghai area in the application of non-metallic materials to build corrosion-resistant storage tank has done some work. Shanghai Dyeing Nine Factory has adopted more water glass acid-resistant concrete monolithic hydrochloric acid storage tank, saving a lot of steel and non-ferrous metals, after more than a year of actual test, the effect is good, the Shanghai Pharmaceutical Factory two years in the two years Factory construction, the use of bricks, concrete lining FRP
