摘要:
A method, apparatus and system for producing an image on one or more surfaces of a gypsum or cement composite substrate by etching the one or more surfaces of the gypsum or cement composite substrate, transferring the image to the one or more surfaces of the gypsum or cement composite substrate using an ink jet process or a rolling die, applying a topcoat on the image and etched surface(s) of the gypsum or cement composite substrate, and curing the image and the topcoat.
摘要:
A composite product includes gypsum in an amount of 60 to 90% by weight, fibers in an amount of 1.5 to 26% by weight substantially homogeneously distributed through the composite, and a rheology-modifying agent in an amount of 0.5 to 6% by weight. The composite is caused or allowed to cure to form a cured composite. The cured composite is a fire resistant component used in a fire-rated door core, a fire-rated door or a fire-rated building panel. The fire resistant component may include a building panel, a door panel, a door core, a door rail, a door stile, a door lock block, a door border, or a door insert.
