摘要： A continuous manufacturing line for preparing gypsum fiberboard is provided. The manufacturing line includes equipment for admixing hydratable gypsum, paper, and a quantity of water to form a substantially homogeneous slurry, dewatering apparatus for removing a portion of the excess water from the slurry to produce a substantially continuous wet web, pressing equipment (36, 40, 44) for configuring the wet web with a compression means to form a substantially continuous green board, a cutting station (41) for cutting the substantially continuous green board into individual uncured lengths (57), and a heating station for curing the individual uncured lengths to form gypsum-dihydrate-containing fiberboards.

摘要： A door frame (10) having excellent fire-resistance, flexural strength and screw holding properties is fabricated from gypsum fiberboard, specifically a gypsum fiberboard having a density of at least 60 lbs./cu ft., a flexural strength of at least 30 lbs. (1/2' thick material), and a screw holding capability of at least about 400 lbs. A preferred gypsum fiberboard material for fabrication of the door frame (10) comprises a composition containing a substantially uniform dispersion of solids including by weight about 65 % to 90 % set gypsum, about 7 % to about 30 % pulped paper, up to about 9 % binder, and about 8 % to 2 % inorganic fiber. A wood veneer (28) is preferably applied to the visible faces of the gypsum fiberboard door frame members by means of adhesive (30).

摘要： Vue isométrique d'une construction (60) de porte coupe-feu, comprenant des panneaux (62) de fibres de gypse ayant une densité d'au moins 60 livres par pied cube, une résistance à la flexion d'au moins 30 livres (matériau d'une épaisseur de 1/2 pouce), ainsi qu'une capacité de maintien de vis d'au moins 400 livres. Ledit panneau a une composition comprenant 65 à 90 % en poids de dihydrate de gypse, 7 à 30 % en poids de fibre de papier, et un agent augmentant l'efficacité choisie parmi une fibre inorganique, de l'argile, la vermiculite, ainsi qu'un polymère de liaison. La structure (66) en nid-d'abeilles est entourée au niveau du périmètre de la porte, par un bandage (65) de bordure de panneau de fibres en gypse, d'une densité préférée de 65 livres par pied cube, et d'une capacité de maintien de vis d'au moins 600 livres par pied cube.
