污水罐的腐蚀原因及其防护措施 朱吉新1 (1.中石化镇海分公司,浙江,宁波,315207) 摘要:炼油厂污水因为含有Cl-,NH3,CN-,S2-和酚类等强腐蚀介质,短时间内就能致使污水罐常规防腐蚀涂层起泡,剥落失效,最终导致罐体穿孔泄露.经现场多种涂料挂片试验筛选,采用WF40含硫污水介质专用防腐蚀涂料对腐蚀介质有很好的防护作用,从2004年使用至今,罐体运行正常,使用效果良好. 关键词:腐蚀防护; 炼油厂; 污水罐; 涂料; corrosion and protection; wastewater tank; oil-refin-ery plant; paint; [全文内容正在添加中] ......
