Description
技术领域
本发明涉及防腐技术领域,尤其涉及一种球罐防腐工艺。
背景技术
球罐常用与存储石化领域中的液体或者气体,一般会承受一定的压力,所以存在一定的危险性。由于球罐一般安装在室外,需要承受风吹雨打,容易老化生锈,生锈的球罐会缩短使用寿命,且还存在一定的安全隐患。所以对球罐进行防腐处理就非常重要。而现有技术中对球罐一般就采用常规的喷砂打磨,涂油漆,每一针对球罐处于特殊的环境,球罐的不同位置进行对应的处理,易出现薄弱环节,造成安全隐患。
发明内容
本发明旨在提供一种球罐防腐工艺,很好的解决上述问题,针对球罐的不同部位所处的环境不同,采取了不同的防腐措施,有效的防止了球罐生锈老化,防腐效果好,安全可靠。
本发明的技术方案是一种球罐防腐工艺,包括步骤:在球罐外表面半球处安装一圈导水槽。
进一步的,还包括步骤:在安装导水槽前,对球罐整体进行喷砂除锈、表面清除灰尘、涂底漆、中间漆、面漆的处理。
进一步的,还包括步骤:在导水槽上方区域,对球罐焊缝处涂抹工业黄油。
进一步的,还包括步骤:在导水槽下方区域,对球罐与支座连接处及支座上涂抹防虫剂。
进一步的,所述喷砂除锈中,所用的压缩空气在0.5-0.7Mpa,喷射距离为 150-200mm,喷射方向和储罐内壁表面法线的夹角为15-30°;喷嘴选用文丘里型喷嘴,磨料选用石英砂,粒度0.5-1.5mm,含水率小于0.9%。
进一步的,所述底漆由A、B两组按照10:1质量比混合、搅匀制成;其中A组:环氧树脂310~345份,钛白粉95~110份,滑石粉80~115份,三氧化二铝210~260份,二甲苯15~45份;B组:三羟甲基丙烷12份,甲苯二异氰酸酯30~40份;
进一步的,所述中间漆由C、D两组按照4:1质量比混合、搅匀制成;其中C组:环氧树脂85~100份,三氧化二铝550~660份,碳化硅50份,碳化钨100~150份,二甲苯8~10份,钛白粉20份;D组:三羟甲基丙烷10~15份,甲苯二异氰酸酯35~45份,活性稀释剂1~2份,碳化钨50份,三氧化二铝75~90份;
进一步的,所述面漆由E、F两组按照4:1质量比混合、搅匀制成;其中E组:环氧树脂320~345份,钛白粉90~120份,滑石粉80~115份,三氧化二铝210~260份,二甲苯15~45份;F组:三羟甲基丙烷10~15份,甲苯二异氰酸酯30~45份。
进一步的,所述导水槽与球罐外面接触紧密,以不从导水槽与球罐间漏水为标准。
本发明的有益效果是:
1、导水槽的设计将球罐分为了上下两个半球,上半球易被雨淋,下半球易被昆虫爬上去,被昆虫的液体腐蚀,针对上下半球处于不同的环境,对其进行针对性的防腐处理;
2、对常被雨淋的上半球,在完成一般防腐后,还在焊缝处涂抹了工业黄油,进一步保证了防腐效果,使雨不易积聚在焊缝处。
3、导水槽的设计使上半球的雨水不会顺着球面流向下半球,防止了下半球被雨水侵蚀。
4、杀虫剂的涂抹,防止了昆虫等从支座爬上球罐,防止了球罐被昆虫的液体侵蚀。
5、本发明采用的喷砂的条件还有底漆、中间漆、面漆的配方,防腐效果好于一般的防腐处理,防腐寿命比原有的提高了20%。
