Ion membrane pinhole test

This post was last edited by sunjl1981 on 2013-1-6 23:48 Is the pinhole test of the ion membrane necessary to be done after the device is overhauled? Or can it be omitted? Will pinhole testing have any impact on the membrane? To clear up my confusion! The cells and membranes currently used by our factory for chlorine work are three years old! # , , &
1. Pinholes in the ion membrane do exist. It depends on what you can accept. This should be especially true in three years.； 2. We use DuPont membrane. Bubble test is generally not performed during overhaul. Even if pinholes are found, only bubble test II is performed. ； 3. Regarding the cells and membranes of chlorine engineering, it is said that pinhole testing cannot be done, but you can feel its existence as soon as you drive the car. ； 4. If there are problems in the drainage operation, bubble testing will have an impact on the membrane. ； 5. It is recommended to change the film according to the production situation to solve this kind of problem. :lol
The new film needs to be repaired after patching. There should be no pinholes in the new film. The last time we bought it, we found pinholes and the agent even compensated us.
I think this depends on the specific situation. If you find a problem with the membrane after doing a membrane leak test during overhaul, you can do it. This will also make it easier for you to understand the operation of the membrane. Just follow the test requirements and be careful during the inspection. There should be no problem. :loveliness: But this is just my personal opinion. If there is anything inappropriate, please point it out! :)
