Asbestos alternative

Asbestos alternative

Asbestos alternative

(OP)
We have Asbestos curtains, surrounding a grinder, used as a fire shield in the rare event of an explosion (it's happened once in the last 20 years).  I would like to replace these curtains with non-asbestos material.  What material can I make these curtains from without loosing the fire protection of asbestos?  Where can I find some?

RE: Asbestos alternative

(OP)
The product we grind is Aluminum Stearate.  The curtains would block the fireball (which lasts barely 1 second) from spreading and igniting something else.

RE: Asbestos alternative

(OP)
What kind of metal mesh/screen?  Would that block flames from passing through?

RE: Asbestos alternative

Hi Zpider:
The metal screen cools the flames below the ignition
temperature preventing the explosion to propagate to
the other side of the screen -- see the coal miner's
safety lamp ( Dawy ?? )

RE: Asbestos alternative

Search for "davy lamp".
A properly designed screen can prevent even H2-O2 explosion
from propagating to the other side. The Al stearate is
a fairly poor explosive... it should take much to extinguish
it.
