在制药过程中,一般都需要无菌操作,特别是药品制造的最后阶段,必须在无菌室中进行。这些无菌操作室近年来采用氯化锂空调净化设备,以LiCl作为净化、杀菌剂。由于目前氯化锂空调设备一般采用国产的1Cr18Ni9Ti奥氏体不锈钢管及管板制造,而净化剂又是含很高Cl~-的氯化锂盐,使设备极易损坏,调查表明,一台价值拾几万元的装置仅用一个多月就发生腐蚀开裂,最短甚至只有一周就发生泄漏。因此,搞清氯化锂净化器加热管的腐蚀开裂原因,有着重要
In the pharmaceutical process, generally require aseptic operation, especially in the final stages of drug manufacturing, must be carried out in the sterile room. In recent years, these aseptic operating rooms have adopted lithium chloride air conditioning and purification equipment, with LiCl as a purifying and bactericide. As the current lithium chloride air conditioning equipment commonly used domestic 1Cr18Ni9Ti austenitic stainless steel tube and tube plate manufacturing, and purification agent is a high Cl ~ - chloride salt, the equipment is extremely vulnerable to damage, the survey shows that one The device that picks up tens of thousands of dollars in value takes corrosion cracking more than a month, with the shortest or even a week. Therefore, it is important to understand the cause of corrosion cracking of the heating pipe of lithium chloride purifier
