用水分不高的粘土成型砖时,使泥料具有良好的流动性是很重要的。在搅泥机中,和水一起加入少量的表面活化剂,能促使矿物的和胶体的粘士微粒均匀地湿润,从而增强泥料的流动性。许多以可塑法成型的砖瓦厂,研究了以下几种表面活化剂:(1)烷基芳基磺酸钠的精馏分,具有阴离子的活化性。(2)冷凝烷基酚和氧化乙烯的产品,在水溶液中不解离。(3)重新中和的烷基 When using clay bricks with low water content, it is important to have good fluidity of the mud. In the mud mixer, adding a small amount of surfactant together with the water promotes the uniform wetting of the mineral and colloidal particles, thereby enhancing the flow of the mud. Many of the plastic brick-molding brick factories studied the following types of surfactants: (1) A fraction of alkyl aryl sulfonates with anionic activation. (2) Condensed alkylphenol and ethylene oxide products do not dissociate in aqueous solution. (3) Re-neutralized alkyl
