Preparation method of pure calcium aluminate cement
The invention discloses a wet preparation method of pure calcium aluminate cement, and particularly relates to a production and preparation process method of the pure calcium aluminate cement. By adopting a full-wet and totally-closed continuous production process, the method has the advantages of no flying dust and good production environment in the production process, solves the problems of long production time and high labor intensity of the conventional wet method due to the adoption of a continuous automatic production method of filter-pressing dehydration, vacuum forming and belt drying, and reduces the production and operation cost by about 30%. A macromolecular sodium salt dispersing agent with hydrophilic groups in a special SD-10 dispersing agent is added, and contained sulfonic acid has steric hindrance and electrostatic repulsion effects, so that the dispersing capacity can be better improved, and the ball milling efficiency is improved.
本发明公开了一种纯铝酸钙水泥的湿法制备方法，具体涉及纯铝酸钙水泥的生产、制备工艺方法。采用全湿法、全封闭连续生产工艺，其优点是生产过程中无扬尘，生产环境良好，同时因为采用压滤脱水、真空成型、带式干燥的连续自动化生产方法，解决了以往湿法生产时间长、劳动强度大的问题，其生产运行成本约降低30%。添加专用SD‑10分散剂中带有亲水性基团的高分子钠盐分散剂，同时含有的磺酸具有空间位阻和静电斥力作用，更能提高分散能力，使球磨效率增加。
