立式储罐常年在各种自然环境和液位变化以及改变储存介质的条件下使用,使用条件非常苛刻,特别是立式储罐的罐底板,受到各种不利影响的因素很多,容易受到各种腐蚀,造成罐底板泄漏。1罐底板腐蚀的形式立式储罐底板在使用中的腐蚀,从机理上来分析可以归纳为2大类:电化学腐蚀和化学腐蚀。电化学腐蚀是金属在介质中由于电化学作用而产生的腐蚀。腐蚀过程中有电流产生,金属的电化学腐蚀过程犹如形成了腐蚀电池。化学腐蚀是材 Vertical tanks are used year-round in a variety of natural environments and liquid level changes and changes in storage medium conditions, the use of very harsh conditions, especially vertical tank cans, subject to a variety of adverse factors, susceptible to Corrosion, resulting in tank floor leaks. 1 tank bottom corrosion form vertical tank floor corrosion in use, from the mechanism analysis can be divided into two categories: electrochemical corrosion and chemical corrosion. Electrochemical corrosion is the corrosion of metals in the medium due to electrochemical action. Corrosion process in the current, electrochemical corrosion of metal as if the formation of a corrosive cell. Chemical corrosion is the material
