Inanimate matter board manufacturing method

Abstract

An inanimate matter board manufacturing method supplies plasm material S from the supply pipe (11) to the plasm supply groove (13), the plasm material S is momentarily stored in the plasm supply groove (13), meantime, the plasm material S is discharged from the discharging port (131) on lower end of the plasm supply groove (13) to upside of the plasm fetching belt (16) to form a roughcast plate GS with determined thickness, a vibration plate arranged under the plasm fetching belt (16) inside the plasm supply groove (13) supplies the plasm material S from the discharging port (131) to the plasm fetching belt (16) in state that the plasm material S is in vibration by the vibration plate (10). Thus even to high density plasm material, the dispersivity of material can be improved, and the thick variation of the roughcast plate in width direction because of variation of liquid surface can be eliminated to improve the uniformity of product without complex control.

Description

technical field

[0001] The present invention relates to a method for manufacturing an inorganic board, and in particular, relates to a manufacturing technique using a flow-on method for papermaking to eliminate the influence of fluctuations in the liquid level of slurry and manufacturing by the method. flat tiles. Background technique

[0002] Well-known now, take cement and reinforcing material as main component to cooperate the slurry of reinforcing fiber as pulping, manufacture the manufacturing method of the inorganic matter plate that is used for building materials such as tile and exterior decoration material. Since this flow method can use a slurry with a relatively high concentration, it is considered to be a method with high production efficiency.

[0003] exist Figure 34 In the figure, a flow method is shown as an example of a conventional inorganic board manufacturing method (for example, refer to JP-A-2002-86439). In this method, the slurry S is supplied from ...
