I'm quite new in the field of ceramic engineering. Here my question is how to remove the bubbles from the ceramic slurry. The vacumm vessel is used and the pressure is set up at -29inHg. There are still a lot of bubbles in the slurry. I'm wondering how long it will be needed for the bubble...
Sorry for this stuip question. NMP is used as solvent. It is noted that the original color is brown or dark brown. Then it turns to yellow or light yellow. As I know it should be colorless or light yellow. Why does the color change so fast? By the way, we saved NMP in the glass bottle.
is it possible that any trace of chloride is on the surface or in the polyethylene sheet? chloride is concerned when we use polyethylene sheet.
Thank you!
I'm looking for the mesh to work with solvent NPM. Does Nylon or PEEK mesh can be used? Are they dissolved in NMP very fast? Any other recommondations? Thanks!
