Description

钛棒过滤机滤芯清洗液
技术领域
本发明涉及清洗液技术领域，具体涉及一种钛棒过滤机滤芯清洗液。
背景技术
钛棒过滤机使用的是钛粉末烧结滤芯，一般用于粗滤或中间过滤。此滤芯具有精度高，耐高温，耐腐蚀，机械强度高等优点，在医药行业广泛应用，外壳材料为316L或304不锈钢。符合GMP标准。
钛棒滤芯在使用一段时间以后,将产生一定程度的堵塞，表现流量减少，过滤前端压力增高，如：从0.22mPa以下升高到0.3mPa以上，这时就要对滤芯进行清洗，清洗方法一般有以下几种：
1、对于新使用的滤芯，一般采用清水反冲，气体反吹的方法来进行清洗，即用稍大于工作压力(如；0.3MPa)的清水反方向注水清洗。反冲时间约为1-3分钟即可。
2、对于多次反冲洗后，过滤效果不明显回升的时候，可用5％以下的盐酸溶液，或8％以下的硫酸溶液，或10％以下的NaoH溶液在常温下浸泡，再用清水洗净。
具体选择用酸洗或碱洗，应视过滤液中杂质容易溶于酸或碱来选择。
