Layered double-metal hydroxide material as well as preparation method and application thereof
The invention belongs to the technical field of solid waste gypsum recycling, and particularly relates to a layered double-metal hydroxide material as well as a preparation method and application thereof. The solid waste gypsum and an aluminum-containing exciting agent are subjected to mixing treatment and curing forming treatment in an aqueous solvent, and the Ca/Al layered double-metal hydroxide material is obtained. According to the preparation method, the Ca/Al layered double-metal hydroxide material is prepared from the solid waste gypsum, waste is turned into wealth, efficient treatment and value-added recycling of the solid waste gypsum are achieved, the preparation process is simple, energy consumption is low, and the prepared Ca/Al layered double-metal hydroxide material has multi-path and multi-functional application.
本申请属于固废石膏回收利用技术领域，尤其涉及一种层状双金属氢氧化物材料及其制备方法和应用。将固废石膏与含铝激发剂在水性溶剂中进行混合处理和养护成型处理，得到Ca/Al层状双金属氢氧化物材料。上述制备方法利用固废石膏制备Ca/Al层状双金属氢氧化物材料，变废为宝，实现对固废石膏的高效处理与增值再利用，且制备工艺简单、能耗低，制得的Ca/Al层状双金属氢氧化物材料具有多途径、多功能应用。
