Patent
CA 2694182
A mat-faced gypsum board and method of making thereof is provided having a particulate matter applied on an inner surface of the facer mat and extending partially into the mat from the inner surface thereof. The particulate matter, which is preferably a hydratable powder such as calcium sulfate hemihydrate, minimizes and, preferably, prevents bleed through of a gypsum slurry during formation of the gypsum board.
L'invention concerne une plaque de plâtre revêtue de mat, et un procédé de fabrication de celle-ci, ayant une matière particulaire appliquée sur une surface intérieure du mat de revêtement, et s'étendant partiellement dans le mat depuis sa surface intérieure. La matière particulaire, qui est de préférence une poudre pouvant être hydratée, comme de l'hémihydrate de sulfate de calcium, minimise et ainsi empêche de préférence une perte à travers une pâte de plâtre pendant la formation de la plaque de plâtre.
