Method of manufacturing wood-cement board

Abstract

A method of manufacturing wood-cement board and an apparatus used in the method are provided in the present invention. The method of manufacturing wood-cement board comprising strewing a raw materials mixture of wood-cement board on a mold panel to form a mat, piling up a plural number of the mats with the mold panels, pre-pressing the piled mats to reduce the thickness of each mat, piling up a plural number of the pre-pressed mat, main-pressing the pre-pressed and piled mats and curing the piled mats being main-pressed and the apparatus used in the method consists of a piling up machine piling up a plural number of mats formed on a mold panel, a pre-press machine pre-pressing the piled mats to reduce the thickness of each mat, a main-piling up machine piling up a plural number of the pre-pressed mats, a main-pressing machine main-pressing the pre-pressed and piled mats, and a curing chamber curing the piled mats being main-pressed. In the present invention, since a plural number of mats are piled up before pre-press process, the pressure effecting on the piled mats can be released slowly to prevent the generation of big negative pressure between mats without delaying pre-press process.
