Method for preparing calcium hydroxide with high specific surface area by low water cement ratio dry method
The invention belongs to the technical field of calcium hydroxide preparation, and particularly relates to a method for preparing high-specific-surface-area calcium hydroxide by a low-water-cement-ratio dry method. The invention provides a method for preparing calcium hydroxide with high specific surface area through a dry method under the condition of low water cement ratio. In the lime slaking process, an additive with a special function is added, so that the water-cement ratio required in the slaking process is reduced, the water content of the product calcium hydroxide with the high specific surface area is relatively low, a complicated drying procedure is avoided, and the process of industrially preparing the calcium hydroxide with the high specific surface area is simplified. According to the method, the operation process is simplified, and large-scale application and production can be realized.
本发明属于氢氧化钙制备技术领域，具体涉及一种低水灰比干法制备高比表面积氢氧化钙的方法。本发明提供了一种在低水灰比情况下，通过干法制备高比表面积氢氧化钙的方法。在石灰消化过程中，通过加入特殊功能的添加剂，降低了消化过程所需的水灰比，也使得产物高比表面积氢氧化钙的含水量较低，避免了复杂的干燥烘干程序，简化了工业制备高比表面积氢氧化钙的流程。本方法不仅简化了操作流程，还有助于实现规模化应用生产。
