fluidized bed

Re: fluidized bed

Im not sure about how well it can coat into recesses and corners but nitrogen can be used as an air source I have seen it used on a powder system before to eliminate moisture problems.

Re: fluidized bed

I understand that the powder is the combustible part, where I'm going here is that the nitrogen will not support combustion, hence a spark would be a non issue. What I am wondering is if the powder will charge sufficiently if I use a "halo" electrode near the bottom and will the cloud reach into the inside corners of the part. I have a plan to build such a vessel, but if someone else has done this and ran into problems I can save my efforts for something else.

Re: fluidized bed

The powder is the explosive part not the air. The only advantage to nitrogen would be dry air.

Hi, I'm new to the board. Have several questions, for now I was wondering if anyone out there has used a fluidized bed to apply powder to a part. This a vat having powder suspended with air..I realize it could be explosive if a spark came off the part, so i was wondering if it would work if you used nitrogen gas..what do you think? I was also wondering how the powder coat stripper stuff worked. Thanks, Dan
