Manufacture of perlite insulating board on a cylinder machine |
| 摘要 |
Perlite insulation board is produced on a rotary vacuum forming machine utilizing an aqueous slurry containing ultrafine perlite particles. The fine perlite particles slow down the rate of stock deposition on the facing wire of the rotary vacuum former, and permit the rotary vacuum former to operate at a desirable forming speed.
