黄河冶炼厂冶金建设公司施工的酸洗槽采用了5毫米厚的铅板作衬里,作为对酸介质的主要防护层(图6)。为了排除可能渗漏的酸洗液,在槽底设有排渗管道(4),与排渗井相连。槽底铅板之下铺有一层木衬板(2),以构成槽底的排渗夹层。设计要 The pickling tank constructed by the metallurgical construction company of the Yellow River Smelting Plant was lined with a 5 mm thick lead sheet as the main protective layer for the acid medium (Figure 6). In order to eliminate the possibility of leakage of acid pickle, a drainage pipe (4) is provided at the bottom of the tank and connected to the drainage well. A layer of wood lining (2) is laid underneath the grid at the bottom of the trough to form an infiltrated interlayer for the bottom of the trough. Design
