Discussion on membrane repair technology of ion membrane
Thread Content
This post was last edited by sunjl1981 on 2013-1-6 23:28 Film repair is a highly empirical job. According to different types of films, different film repair times and cooling times need to be selected.... Is anyone willing to discuss their experience in film repair? Why did we repair the ion membrane on the same membrane with the same welding gas source pressure, time and temperature? Why did some of the patches fall off and some were well adhered? Also, after the repaired membrane was installed in the groove, when it was removed next time, it was found that some of the patches had turned white, while others were the same as before. Does anyone know what is going on? # hcbbs
1# n.bsr In fact, it is not difficult to repair the film. The important thing is to master the temperature and position (of course, the front and back)
Repair film = welding film, my colleague told me so! :lol
Nowadays, it is rare to repair the membrane. If the membrane is damaged, it is best to replace it, otherwise it will be a small loss. Different types of membranes have different degrees of wear, ambient temperature and humidity, and their service life is different. Different film thicknesses and different strengths may have a certain impact on film replenishment. It requires a certain amount of practical experience and theoretical knowledge for guidance, so there are very few mending membranes. Pay attention to the following aspects: Hot melt time, cooling time, air source pressure, heating platform temperature, air source gas cleanliness, ethanol cleaning leaks must be cleaned, and after cleaning, be sure to blow dry with air before welding.
There are only a few pinholes in a film. Isn’t it a waste? Isn’t the cost of a new film higher? A certain amount of experience is gained by time. After repairing a film, you can see whether it is good or bad. You have to wait until it is installed and replaced next time to observe whether the result is good or bad.
Where can I buy a film patching machine? I want to buy one.
In fact, the work of repairing the membrane is also very profound. 1. The three major manufacturers of Asahi Kasei, Asahi Glass, and DuPont are different. 2. Perfluorosulfonic acid, perfluorocarboxylic acid, and composite membranes are different. 3. High electrical density, low electrical density, and sacrificial core materials are different.
Don't buy it, it's too expensive. The domestic ones cannot be used, they are too rubbish.
