Asahi Kasei technical support

This post was last edited by Du Xiaoping on 2016-2-26 at 10:08. I would like to ask: 1. After a negative pressure difference appears in the electrolyzer, what is the maximum allowable value of this negative pressure difference for F-6801 ion exchange membranes and NCZ electrolyzers, and how long can this negative pressure difference be maintained? (Zero-gap electrolyzer). Once a negative pressure difference occurs, what is the impact on the electrolyzer and the ion exchange membrane? Has this happened to any manufacturers? If so, what would be the consequences? 2. What is the anti-pollution capacity of the F-6801 ion exchange membrane? In particular, the ability to resist iodide ions and the required specifications. 3. For NCZ cells that have been in operation for four years, what voltage is considered normal? (Current density: 5 KA/m2) (New membrane F-6801) 4. What is Asahi Kasei’s latest model of ion membrane? And features. 4. What is the latest model of Asahi Kasei’s ion exchange membrane? And what are the features? There are quite a few issues; thanks in advance!

My questions are: the impact of the TOC content in saline on current efficiency and cell voltage. Hope the original poster will share it

There’s another question: I saw online some claims that in Asahi Kasei’ s electrolyzers, liquid is no longer drained without replacing the membrane. Is this true or false? Could failing to drain the liquid for an extended period of time cause damage to the ion membrane? If that’s true, how is it done exactly? Could you provide some reference materials? sanqi2009@163.com

Ask them to explain the principle of circuit breakers! Instead of using a polarized rectifier in existing devices, the principle of a circuit breaker is adopted

I want to know the status of implementing the above issues!

Don’t you use the F-6805 ion membrane? The temperature control of the F-6805 ion membrane is kept below 90 degrees, while that of the F-6801 must be kept below 87 degrees
