摘要
针对锆管的去氧化皮酸洗中操作困难、易出现过酸洗的现象,进行了酸液配比和酸洗时间对锆管酸洗效果影响的对比试验。研究结果表明,酸洗液以氢氟酸、硝酸和水按质量比3:45:52配制,在温度32℃下酸洗锆管,酸洗时间为120s时,能够获得干净光洁的酸洗表面,而且能较好的避免过酸洗。
In the matter of pickling the oxide - skin of zirconium tubes, it is complex to operate and easy to excessive pickling. According to this situation, the contrast tests were devised by selecting different acid proportions and adjusting different pickling time. The results show that when the temperature is 32 ℃, the mass ratio of HF ： HNO3 ： H2O is 3：45：52, pickling time is 120 s, the clean and bright surfaces can be obtained and can avoid excessive pickling effectively.
