When the single cell of the chlorine engineering electrolytic cell starts to increase the current, there is a unit cell. The cell voltage does not begin to rise until 3.2KA. The overflow pipe begins to change color. Will there be pinholes in the film?
Not necessarily, there may be pinholes, or it may be caused by slow reaction. After the current stabilizes, check the hydrogen content in the chlorine in this unit tank to see if it is high.
1. When measuring the tank pressure, other measuring points of the unit tank can also be measured and compared. 2. Test again at 5kA/8kA and observe the difference in tank pressure with other units. 3. Do a membrane leakage check before driving.
Measure the voltage when the current is 500A. If the voltage is 0.08V lower than other normal cells, it means there are pinholes in the film. Judging from the fact that the anode outlet does not discolor, there must be pinholes in the film and they are relatively large.
If the single tank is not installed, if it leaks, the film will not need to be replaced.
If the amount of leakage is large, of course the membrane needs to be replaced. It's a matter of trade-off, will the amount of leakage cause a safety issue? Safety issues should be taken seriously, and we should not take such big risks by not getting more than we gain.
Does the manufacturer require that the voltage be measured at 500A? The current is too low and the hydrogen content in chlorine is relatively high, making it unsafe. In addition, the temperature is too low and it is not suitable to stay.
