Problems solved by technology

[0003] However, in the production process of gypsum board, due to factors such as low extrusion force of the press machine, long time for the slurry to enter the extrusion board, and short initial setting time of the slurry, more uneven pores will be generated in the gypsum board, reducing the The quality of the board affects the strength and aesthetics of the gypsum board

Embodiment Construction

[0029] In order to make the purpose, technical solution and advantages of the present invention more clear, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined arbitrarily with each other.

[0030] An embodiment of the present invention provides a device for improving the uniformity of pores in a gypsum board, including a molding board, a pressing board, an extrusion board and a molding knife,

[0031] The forming plate is connected with the extruding plate, and the pressing plate is set at the connection between the forming plate and the extruding plate. A forming knife is arranged under the forming plate and the extruding plate. One side of the forming knife is also connected with a forming knife slant plate. The forming knife and the forming plate , There is a...

Abstract

The method for improving the pore uniformity of gypsum board provided by the present invention, by adding retarder and water reducer in the production process of gypsum board, prolongs the initial setting time of slurry, improves the fluidity of slurry, and can effectively increase the The width of the slurry discharged from the mixer is spread, so that the slurry enters the extrusion plate faster, and prevents the edge slurry from reaching the initial setting before entering the extrusion plate. The device for improving the uniformity of the pores of the gypsum board provided by the present invention sets the height of the front end of the extrusion board to 30-40mm and the length to 400-500mm, which can effectively improve the situation that the extrusion angle of the pressing board is too high and the extrusion force is low. Avoid the larger air holes that are involved in the stacking position and easily enter the extruded plate. Set the height of the forming knife slant plate to 5-15mm, and the width to 25-35mm to shorten the time for the edge slurry to enter the extrusion plate, and avoid excessive, uneven, and Problems such as slurry delamination have greatly improved the quality of gypsum boards.

Description

technical field [0001] The application relates to the field of building materials, in particular to a device and method for improving the uniformity of pores of gypsum boards. Background technique [0002] Gypsum board is a building material with light weight, high strength, thin thickness, convenient processing, sound insulation, heat insulation and fire resistance. It is one of the new lightweight boards that are currently being developed. Gypsum board has a wide range of application scenarios. At present, it has been widely used in interior partition walls, wall cladding panels (instead of wall plastering layers), ceilings, and sound-absorbing panels of various buildings such as residences, office buildings, shops, hotels, and industrial plants. , ground base panels and various decorative panels and other scenes. [0003] However, in the production process of gypsum board, due to factors such as the low extrusion force of the press machine, the long time for the slurry t...
