Peephole will be blurry
Thread Content
The peephole of the reduction reactor will be blurred and a white substance will be produced, but it is not silicone oil. Experts, how can we prevent this phenomenon? Is it because the water temperature is low or the amount of hydrogen in the peephole is small?
1. Strictly control the temperature in the furnace, not too high or too low. 2. Keep the temperature of the furnace barrel water high. 3. On the basis of normal heat dissipation, increase the temperature of the sight hole water. 4. Preheat the sight hole hydrogen. The amount can be increased. In one word, strictly control the temperature.
The blurred sight glass is mainly related to the cooling method.
In fact, it’s fine without purging hydrogen.
The temperature of the sight hole is too low. It should be possible to increase the temperature of the cooling water of the sight hole appropriately. It is also possible that the content of trichlorosilane in the mixed gas is relatively too high.
I also want to know the reason. It probably has a lot to do with the temperature of the sight glass. I hope an expert can give me some authoritative solutions.
How high should the temperature of the cooling water in the viewing hole be increased?
White stuff? Silica? I wonder what other white ones there are? What is the dew point of purge hydrogen?
