Abstract
Det er beskrevet en fremgangsmåte for fremstilling av en forbedret gips/trefiberplate. Det er også beskrevet produkter som oppnås ved prosessen. Fremgangsmåten omfatter tilsetning av et diisocyanat, nærmere bestemt metylendifenyldiisocyanat (MDI) til en vandig oppslemming av kalsiumsulfatmatetiale og celluloseformige fibrer, hvor MDI tilsettes som en emulsjon som er stabil i betingelsene hvorunder oppslemmingen holdes. Fremgangsmåten omfatter videre føring av den MDI-holdige oppslemmingen på en flat porøsformende overflate for å danne en filterkake; fjernelse av en betydelig del av vannet fra filterkaken gjennom den porøse overflaten; pressing av filterkaken for å danne en plate og å fjerne ytterligere vann; og tørking av platen for å fjerne det gjenværende frie vannet.
