Preparation process of fiber cement slab or fiber gypsum board as well as production line

Abstract

The invention discloses a preparation process of a fiber cement slab or a fiber gypsum board as well as a production line, as shown in drawings, comprising an integrated console (9), a feeder (23), acast-molding device (24), a cutter (12) and a post-maintaining and drying conveyer (25). The feeder (23) is provided with a material storage bin (1), an initial lifter (2), a dry powder blender (3), an iron remover (16), a secondary lifter (4), a mixture bin (6) and an arch-breaking device (17); the cast-molding device (24) is provided with a metering conveyor (7), a water and fiber synthesizer (8), a water and powder blender (18), a distributor (19), a grid frame (20), a vibrator (21), a vacuum water pumping device (22), a compression belt (10) and a molding frame (11); and the post-maintaining and drying conveyer (25) is provided with a conveying line (13), a maintaining and drying furnace (14) and an automatic conveying table (15). The production line meters and feeds the materials andcontinuously works, the fiber cement slab or the fiber gypsum board prepared by the process of the invention has largely improved pressure resistance, bending resistance and toughness.

Description

technical field [0001] The invention belongs to the technical field of construction machinery and relates to a fiber cement board or fiber gypsum board production process and production line with reasonable equipment structure and simple production process. Background technique [0002] At present, the traditional cement or gypsum wallboard production lines distributed in the construction industry generally have problems such as low degree of mechanization, backward production technology, and waste of raw materials. Most of the traditional cement or gypsum boards are made by casting or semi-dry extrusion Or the copying method is the production method. The products produced by the pouring method have low compressive and flexural properties, and the products produced by the semi-dry extrusion method have poor flexural resistance and toughness. The production process of the copying method is complex and highly polluting. high cost. Contents of the invention [0003] The tech...
