Abstract

The invention provides a laboratory simulation device and method for producing a calcium silicate board through a flow slurry method and a Hatschek method. The device comprises metering devices, a stirring device, a static curing device, an autoclaved curing device and a drying device, and the device further comprises a suction filtration device used for conducting suction filtration and dehydration on stirred and mixed calcium silicate board slurry to form small material layers, a blank moving device used for moving the small material layers into a molding mold and a pressure molding device used for conducting pressurizing molding on the multiple stacked small material layers. The device can completely and truly simulate the process of preparing the calcium silicate board through the flowslurry method and the Hatschek method, and can assist in analyzing the generating reasons of all defects of the board in practical production and exploring solving methods; and the molding method comprising the steps of multiple times of vacuum suction filtration and dehydration, stacking and pressurizing can truthfully reflect the small material layer vacuum water filtering and small material layer stacking and pressurizing molding process of a linear board making machine in the industrial production board making process, and can assist in analyzing the board delamination reasons in actual production and exploring solving methods.
