    摘要： The invention provides a board forming system comprising a forming table comprising a belt with a surface for conveying a backing layer; a mixer fitted with a mechanism capable of depositing cementitious slurry material over a top surface of the backing layer; and a slurry spreader positioned downstream of the mixer, wherein a portion of the slurry spreader comprises a plurality of apertures which are connected to a source of pressurized fluid. The slurry spreader is configured such that the pressurized fluid flows out of the slurry spreader through the apertures so as to provide a continuous film of fluid across an outer surface of the slurry spreader. The slurry spreader is positioned such that it can contact at least a portion of the cementitious slurry after the slurry exits the discharge and before the slurry is spread across the width of the backing layer such that the thickness of the slurry is approximately equal to the desired slurry thickness for board formation. The invention further provides methods for forming cementitious board comprising the use of the slurry spreader.

    摘要翻译： 本发明提供了一种板形成系统，其包括一成形台，该成形台包括一带和一用于输送背层的表面的带; 该混合器装配有能够将胶结浆料材料沉积在背衬层的顶表面上的机构; 以及位于所述混合器下游的浆料撒布机，其中所述浆料撒布机的一部分包括连接到加压流体源的多个孔。 浆料撒布机构造成使得加压流体通过孔从浆料撒布机流出，以便在浆料撒布机的外表面上提供连续的流体膜。 浆料撒布机被定位成使得其在浆料离开排出物之后并且在浆料分布在背衬层的宽度之前可以接触至少一部分水泥质浆料，使得浆料的厚度大致等于期望的 板形成浆料厚度。 本发明还提供了用于形成水泥基板的方法，其包括使用浆料撒布机。
