Abstract
A method includes outputting a semi-product of a core material for a gypsum board from a mixing tank. High-molecular adhesive is coated on inner faces of first and second outer layers that are bonded to two sides of the semi-product with the inner faces of the first and second outer layers engaged with the sides of the semi-product of the core material. After taking shape, the semi-product is severed and dried to obtain the core material for the gypsum board with the high-molecular adhesive forming high-molecular bonding layers between the core material and the first and second outer layers. The resultant gypsum board includes a core material and first and second outer layers securely bonded to two sides of the core material by high-molecular bonding layers formed by the high-molecular adhesive. Thus, the first and second outer layers are less likely to peel from the core material.
