    • PROBLEM TO BE SOLVED: To provide a novel plasterboard and a method of manufacturing the same. SOLUTION: This novel plasterboard has two first parallel tapered edges on one surface, and has two other parallel tapered ends or tapered edges orthogonal to the first tapered edges on the other surface, or has two first parallel tapered edges on one surface, and has two other parallel horizontal directional tapered ends or tapered edges orthogonal to the first tapered edges in any of the same surface or the other surface, and such the other parallel tapered ends have a width of 100-200 mm. Alternatively, the novel plasterboard has two first parallel tapered edges on one surface, and has two other parallel horizontal directional tapered ends or tapered edged orthogonal to the first tapered edges in any of the same surface or the other surface, and such the other parallel tapered ends have a width such as being 1.5-5 in the ratio of a width of the second parallel tapered edges to a width of the first parallel tapered edges.

    • A process for manufacturing plasterboard and a plasterboard manufacturing unit are provided, the process including feeding hydratable calcium sulphate and water into a first mixer (2) and into a second mixer (3); feeding in a facing (5); preparing a first gypsum slurry in the first mixer (2); preparing a second gypsum slurry in the second mixer (3); applying the first slurry onto the facing and forming a crude surface layer; applying the second slurry onto the crude surface layer and forming a crude core layer with a density lower than that of the crude surface layer; forming a plasterboard; hydrating and drying the board. This process allows the formation of the different layers of gypsum to be controlled independently.
    • 提供了一种用于制造石膏板和石膏板制造单元的方法,所述方法包括将可水合的硫酸钙和水加入到第一混合器(2)中并进入第二混合器(3)中; 喂食面(5); 在第一混合器(2)中制备第一石膏浆料; 在第二混合器(3)中制备第二石膏浆料; 将第一浆料施加到面上并形成粗糙表面层; 将第二浆料施加到粗表面层上并形成密度低于粗表面层的粗芯层; 形成石膏板; 水化和干燥板。 该过程允许独立地控制不同层石膏的形成。
