分馏塔顶油气冷却器列管腐蚀穿孔原因分析

通过对分馏塔顶油气冷却器列管腐蚀穿孔形貌观察，金相分析，断口扫描电镜形貌分析及腐蚀物分析，认为分馏塔顶油气冷却器列管腐蚀穿孔原因是由外壁点腐蚀开始，然后在腐蚀坑中形成应力腐蚀裂纹，并向内壁面扩展、腐蚀直至穿透壁面发生泄漏。

Ground-based investigation of atomic oxygen effects on naked Ag and Ag with protective organic coating

Protective behavior of organic coatinge of alkyd,epoxy,urethane and siloxance applied to silver solar cell interconnects and erosion of Ag were investigated by exposure experiments to ground simulation atomic oxygen(AO).Evaluations of their protective properties were made through assessing their mass cfhange characteristics,chemical and physical changes to Ao attack.The specimens,after exposure were analyzed with SEM/EDAX and XPS.The results indicated that the silver is heavily etched.some coatings such as epoxy,alkd,urethane are seriously degraded or removed as volatile oxides and morphology of coatings changes.It is evident that siloxane coatings have excellent properties for anti-AO attack.The erosion product consists of silicon dioxide layer of compact texture and is left on the surface to provide adequate protection fro further attack by the energetic AO.

碳黑洗涤水分离器出口主管道上短管爆破原因分析

通过采用宏观分析、厚度检测、硬度测试、材质成分分析、环境介质分析以及金相组织分析等手段，从多方面对化肥厂合成车同碳黑洗涤水分离霉出口压差开关引压管的爆破事故进行了综合分析和研究，分析结果表明,爆破是由于短管和法兰焊接处的未焊透缺陷以及硫化氢电化学腐蚀的共同作用所造成的．     

冷却水致锌粉炉冷凝器穿孔的对策

由于冷却水中悬浮物含量过高(75.4mg/L),污垢沉积,导致垢下腐蚀,引起锌粉炉冷却器穿孔。采用5%～7%HCl+0.5%HF清除冷凝器污垢和腐蚀产物,再通过冷却水预处理减少悬浮性杂质,调节pH7.5～8.0,加入水处理剂,腐蚀基本得到控制。
