    • A method for producing a light gypsum board, characterized in that it comprises a step of adding in advance a void size adjusting agent being capable of adjusting a size distribution of foams dispersed in a foamed gypsum slurry to an original fluid of a foaming agent or a mixture of the original fluid of the foaming agent with water, to thereby prepare a foaming agent which forms foams having a desired size distribution. The method allows the production of a light gypsum board having a gypsum core of high strength and exhibiting excellent adhesiveness between the gypsum core and a lining paper for the gypsum board and also allows the adjustment of the size of voids in a gypsum core of a light gypsum board product within a desired range, in a short time and at a low cost, even when types and the compounding ratio of gypsum raw materials are changed.
    • 一种轻质石膏板的制造方法,其特征在于,其包括以下步骤:预先添加空隙尺寸调整剂,其能够将分散在发泡石膏浆料中的泡沫的粒度分布调整为发泡剂的原液或 将发泡剂的原液与水的混合物,从而制备形成具有所需尺寸分布的泡沫的发泡剂。 该方法允许生产具有高强度的石膏芯的轻质石膏板,并且在石膏芯和用于石膏板的衬里纸之间表现出优异的粘合性,并且还允许调节光的石膏芯中的空隙的尺寸 即使在石膏原料的种类和配合比例发生变化的情况下,也可以在短时间内以低成本进行所需范围的石膏板制品。
