一种新型的彩色泡沫瓷砖在国外研制成功。它是以粘土、长石为基料,掺入一定量的颜料,再加入少量的碳化硅发泡剂制成的。制作时将上述材料混合、制成料浆,压滤脱水,形成泥饼,经干燥粉磨,干法压坯,烧结或将喷雾干燥的不含颜料的非发泡性陶瓷粉料与喷雾干燥的含颜料的发泡性陶瓷粉 A new type of color foam tiles developed successfully in foreign countries. It is clay, feldspar as a base material, incorporation of a certain amount of pigment, then add a small amount of silicon carbide blowing agent made. During the production, the above materials are mixed to form a slurry, which is filtered and dewatered to form a mud cake, which is dried and compacted with a green compact, sintered or spray-dried, and the spray-dried non-pigment non-foamed ceramic powder is spray- Of the pigment-containing foamable ceramic powder
