Ultrahigh-whiteness white aluminate cement and preparation method thereof
The invention relates to the technical field of special cement, and provides ultrahigh-whiteness white aluminate cement and a preparation method thereof. The traditional aluminate cement is limited by raw materials and processes, the whiteness of the product is low (generally 50-65 degrees), and the whiteness requirement of a decorative material is difficult to meet. Calcareous raw materials and aluminum raw materials are mixed and ground into raw materials, the raw materials are tabletted in a high-temperature furnace (under laboratory conditions) or raw material powder is fed into a rotary kiln and calcined for a certain time by adopting petroleum coke and biomass composite fuel (under industrial production conditions), clinker discharged from the kiln (furnace) is cooled to 100 DEG C or below, and aluminate clinker is obtained; the aluminate clinker is directly ground to a certain fineness to obtain the ultrahigh-whiteness white sulphoaluminate cement.
本发明涉及特种水泥技术领域，提供一种超高白度白色铝酸盐水泥及其制备方法。传统的铝酸盐水泥受到原料和工艺的限制，产品白度较低(通常在50～65度)，难以满足装饰材料的白度要求。本发明采用石灰质原料和铝质原料配料，磨细制成生料后，压片在高温炉(实验室条件)或生料粉喂入回转窑采用石油焦和生物质复合燃料(工业生产条件)煅烧一定时间，出窑(炉)熟料经冷却到100℃以下，得到铝酸盐熟料，将铝酸盐熟料直接粉磨到一定细度，得到超高白度白色硫铝酸盐水泥。
