Method for applying polymeric diphenylmethane diisocyanate to cellulose/gypsum based substrate |
摘要 |
The disclosed invention consists of a means for conveying a gypsum or gypsum/cellulose fiber board to a rotary cylinder brush station where pMDI resin is delivered onto the rotary cylinder brush just as the board passes under the brush. A resin distribution system is used to coat the rotary cylinder brush applicator with pMDI. Optionally, a second rotary cylinder brush station is included, if desired, to smooth out and spread the pMDI resin over the surface of the gypsum board substrate to achieve complete coverage.
