Need barrier like PVC curtain strips but much lighter

I'm looking for a material to use as a curtain to stop one wash stage that contain 3% chromic acid, 2% phosphoric acid and 1.5% hydrofluoric acid from going upstream to the previous stage that is a rinse. The curtain material needs to be four feet long and able to contain the mist from the acid stage as well as be light enough to allow parts to pass through on a conveyor. I have PVC curtain strips in now but they're not doing the trick. They stick together and pose an almost impossible barrier for the parts as they pass through on the belt.

I was thinking about a nylon mesh.

Hi Dale,

'twould have been helpful had you given the thickness,etc. of those PVC curtains ... I assume you are talking about strips. But why 'strips'? Why not a solid curtain?

Had you considered thinner PVC ? After all, swimming pool liners are only l2 gauge or so, eh?

I am not enamoured with nylon.... we never, ever, ever used that for any corrosion application.

Another idea is to use an air curtain. But this means a push fan and a collector hood on the other side. Commercially Blackstone used this for 'wiping' the fluxed radiator grids but due to the liquid capture, a mist eliminator (blade type PLEASE) was in between.
