FIELD: methods of production of interior-lining products made out of gypsum.
SUBSTANCE: the group of inventions is pertaining to the methods of production of interior-lining products made out of gypsum and may be successfully used at production of construction materials. The technical result of the group of inventions is a development of less expensive method of production of interior-lining figured mosaic made out of gypsum with improved hardness of the face surface for the walls and ceilings lining differing by production process, simplicity of production allowing at minimum costs to ensure the high quality of produced products with conservation of original natural advantages of gypsum. And also to create the mold for of interior-lining products made out of gypsum, that is more wear-resistant, easy in production even in simple conditions without power inputs and usage of complex mechanisms. The method of production of interior-lining figured mosaic made out of gypsum bindings provides for, preparation of molding mixture, its pouring in the mold entirely made out of a firm material and equipped with a figured clamp plate, aging till complete solidification, extraction, drying of a product and deposition of a decorative coating differs that solution is poured into the mold in an amount, that is less than the working volume of the mold. For Increase of hardness use hydrophilic material and as a decorative coating use a dry mixture of gypsum. The wear-resistant mold for production of interior-lining products made out of gypsum differs, that its working and support parts are entirely made out of a firm material by a method of a cold molding. At that the mold has the transparent figured bottom, the figured internal walls of sides and is supplied with a double clamp plate made with a capability of a rest on the running-in lapping site.
EFFECT: the inventions ensure less expensive method of production of interior-lining figured mosaic made out of gypsum, improved hardness of the face surfaces of walls and ceilings lining, simplicity of production process, high quality of produced products.
