Application method of plant fibers in mesh gypsum board

Abstract

An application method of plant fibers in a mesh gypsum board belongs to the field of waste resource utilization. The method comprises the following steps: 1, removing impurities from plant wastes, andcrushing the plant wastes; 2, desugaring and deacidifying the crushed plant wastes; 3, mixing and stirring the treated plant wastes obtained in step 2 and a gypsum slurry; 4, adding the mixed and stirred gypsum slurry into a slurry stirring device in a continuous production line for the gypsum board; 5, lacing a mesh fabric coil on a paper roll mounting device of the continuous production line for the gypsum board; 6, turning on the continuous production line for the gypsum board; and 7, cutting the gypsum board with a continuous length according to use requirements. The method has the characteristics of improvement of the performances of the gypsum board, comprehensiveness in utilization of wastes, and reduction of environmental pollution.

Description

technical field [0001] The invention belongs to the field of resource recovery and utilization, and particularly relates to an application method of waste plant fibers in mesh-faced gypsum boards. Background technique [0002] Plants, usually referring to trees, bamboo, grass, straw, etc., often exist in daily life. When plants change seasons or die, these plants were often used as fuel for burning. Due to the tissue characteristics of plants, they will burn when burned. Produce a large amount of polluting emissions, or use it as fertilizer for plants after a long period of natural decay; with the improvement of environmental protection requirements, it is basically forbidden to burn plants for heating in various places, and the period of natural decay as fertilizer is long and the effect is not good; at the same time, because of these There is a large stock of plants, especially in mountainous areas, and they will be left as they are. Because of the large stock, they are pr...

[0002] Plants, usually referring to trees, bamboo, grass, straw, etc., often exist in daily life. When plants change seasons or die, these plants were often used as fuel for burning. Due to the tissue characteristics of plants, they will burn when burned. Produce a large amount of polluting emissions, or use it as fertilizer for plants after a long period of natural decay; with the improvement of environmental protection requirements, it is basically forbidden to burn plants for heating in various places, and the period of natural decay as fertilizer is long and the effect is not good; at the same time, because of these There is a large stock of plants, especially in mountainous areas, and they will be left as they are. Because of the large stock, they are prone to fire and cause fire hazards to people's production and life. However, these plants are high in fiber content, with light weight, good toughness, etc. At the same time, because it is waste, the cost of acquisition is low, which is a pity to cause waste and fire hazards; on the other hand, gypsum board is one of the commonly used building materials, usually used for decoration, with no pollution, stable performance, and low cost. etc., however, the existing gypsum boards must adopt the method of double-sided stickers in production and application, because the existing gypsum powder for the production of gypsum boards has low strength and is fragile, and it needs to use the strength of the outer surface stickers to make up for it. Its strength is insufficient; because the strength of the paper is high, the paper for the veneer must use the original pulp paper, which will relatively increase the production cost; because the surface is made of stickers, in the process of decoration, it needs to be When the surface is decorated with other decorative layers again, the base of the decorative material is paper. If the paper is damp for a long time, it will cause the surface decorative layer to fall off, which will affect the application and appearance. Based on the above reasons, gypsum board is used in the field of architectural decoration. The application of the gypsum board is limited; therefore, the applicant first applied for a Chinese invention patent (application number: 2018108982834), using high-strength gypsum powder, combined with the mesh surface, to improve the performance of the gypsum board and expand the application range of the gypsum board. And it can realize continuous production; in the process of use, it is found that although the mesh gypsum board has good performance, its poor toughness and heavy weight are still defects.
