Description

耐腐蚀快速修补剂
本发明涉及一种耐酸、耐碱的化工设备修补材料。
化工生产设备泄漏后,一般采用焊接修复,多数情况下必须停产。另外一些零部件的防腐层被介质腐蚀破坏后,用衬橡胶、酚醛胶泥、呋喃胶泥、环氧胶泥等修复,亦需要几天时间,修复后的设备,耐腐蚀性能也不甚理想。因此需要寻找生产设备泄漏后,不需停产就能修复,而且能耐腐蚀、耐温、快速固化的既经济,原料又易得的耐腐蚀快速修补剂。为此特完成本发明。
本发明所述耐腐蚀快速修补剂呈糊状。其配方及重量比如下:
a、粘结剂 100份;
b、改性剂 20~50份;
c、固化剂 30~60份;
d、促进剂 3~5份;
e、填料 100~200份。
其中a可以是环氧树脂类,
b可以是酚醛树脂、呋喃树脂;
c可以是T31固化剂、低分子量聚酰胺、乙二胺;
d可以是苯酚、2、4、6-三〔二甲胺基甲基〕苯酚;
e可以是耐酸瓷粉、长石粉、辉绿岩粉、钛白粉、石墨粉、石英粉。
在上述配方中,可根据待修补的设备所处理介质的PH值,选择不同粘结剂和填料,以满足耐酸或耐碱的要求。
使用时,将需要修补处除去锈蚀层和污垢,将配好的修补剂涂在需修补处,按实,经30分钟至1小时手触硬化即完成修补,设备或零部件即可交付使用。这就使化工生产设备泄漏后不用停产焊补,在设备正常运转或在单机轮空中直接用此修补剂即可解决泄漏问题。一些小型设备零部件需要衬防腐层,也可用此修补剂,只需很短时间就能完成。
耐腐蚀快速修补剂比焊补具有耐腐蚀、耐温、快速固化、不需设备停产就能完成修复的特点。特别是对连续化生产线及开停车程序要求较严的操作单元,这一特点就更显出极大的优越性。配方中各原料易得,并且对小型设备零部件衬防腐层具有比其它材料经济、用工时短、能提前投入使用优点。
实例1:
用于硫氢化钠设备,负压下运行,介质PH=10。
配方如下:
6101环氧树脂 100份
酚醛树脂 30份
T31固化剂(江苏昆山助剂厂工业品) 40份
2、4、6-三〔二甲胺基甲基〕苯酚 3份
辉绿岩粉 100~150份
实例2:
用于碳化槽,常压下运行,介质PH=1~3
其配方如下:
6101环氧树脂 100份
呋喃树脂 30份
T31固化剂(江苏昆山助剂厂工业品) 40份
2、4、6-三〔二甲胺基甲基〕苯酚 3份
石墨粉 100份。
