[0071] (1) Preparation of mixture: Mix light-burned magnesia powder or a mixture of light-burned magnesia powder and quicklime, mineral admixtures, various aggregates and water according to the ratio of raw materials and stir them evenly to make a slurry . The equipment and process used for raw material metering, mixing and stirring can adopt existing known equipment and process.
[0072] (2) Mixture forming: the slab forming process can adopt the existing well-known plate forming process, such as: extrusion forming process, group vertical mold pouring forming process, etc. During the molding process, the prefabricated fiber cloth can be laid manually into the mold or the fiber-jet machine can be used to spray chopped fiber into the mold. The length of the chopped fiber should be controlled at 10-30mm. Before molding, a prefabricated rib skeleton must be placed in the mold.
[0073] (3) Pre-curing: The pre-curing of the board can adopt the same curing conditions as the above...
