Abstract

DC60 (11/12/46) This invention reveals a gypsum wall product consisting of an outer gypsum board and an inner core made of calcined gypsum, an air entraining agent, a solu potasse, and lightweight aggregate, and its manufacturing process. This invention addresses the shortcomings of conventional concrete and gypsum wall panels, resulting in a new type of semi-finished interior wall that is strong, robust, impact-resistant, easy and quick to install, and possesses fire, sound, and thermal insulation properties.

This invention addresses the shortcomings of conventional concrete and gypsum wall panels, resulting in a new type of semi-finished interior wall. Durable, strong, impact-resistant, easy and quick to install, and features fire protection, soundproofing, and heat insulation.

Claims (5)

1. Gypsum wall products, enhanced for strength and durability, consist of an outer layer of gypsum boards placed opposite each other, and a middle layer of plaster mixed with lightweight aggregate interwoven between the two outer layers. The middle layer comprises 30 to 60 kg of calcined gypsum plaster, 40 to 45 ml of air entraining agent, 490 to 510 g of solu potasse (hardening agent), 0.9 to 1.5 kg of polystyrene foam beads or 5 to 7.5 kg of vermiculite, and 45 to 85 liters of water. 2. Manufacturing Process of Gypsum Wall Products under Patent 1 - Mix plaster, dispersing agent, hardener, and lightweight material with water. - Pour the resulting thick liquid into the space between two gypsum boards placed back-to-back in a mold, allowing the thick liquid to form a core for the wall to increase its strength and durability. - Remove the wall from the mold and dry it in an oven. 3. The process as per claim 2, which may involve spraying adhesive onto the back of the gypsum boards facing each other before they are placed in the formwork to increase the adhesion between the gypsum boards and the core of the wall panel. 4. The process described in claim 3 is characterized by a drying temperature for the wall panels ranging from 60 to 90 degrees Celsius, with the optimal range being 70 to 80 degrees Celsius. 5. The process described in claim 4 is specific to the drying time of the wall panels, ranging from 45 to 90 hours, with the optimal range being 45 to 60 hours for polystyrene foam lightweight material and 80 to 90 hours for vermiculite lightweight material.
