Preparation method of nanoscale liquid calcium hydroxide
The invention provides a preparation method of nanoscale liquid calcium hydroxide, and relates to the technical field of preparation of calcium hydroxide. The preparation method of the nanoscale liquid calcium hydroxide comprises the following steps: S1, pretreating raw materials; s2, calcining and grinding the raw materials; s3, preparing a mixed solution; s4, carrying out digestion treatment; and S5, centrifuging and mixing. The raw materials are subjected to primary screening, primary cleaning and secondary screening, the uniformity of the volume of blocky limestone during calcination is improved, calcium oxide powder obtained through calcination is subjected to smashing and grinding treatment, the calcium oxide powder reaches the nanoscale, the ion density is increased, and the calcium oxide content is increased. The calcium oxide powder is more sufficiently mixed with water in the digestion process, so that the efficiency of converting calcium oxide into calcium hydroxide is improved, meanwhile, in the digestion process, waste residues obtained after the digestion reaction are dried and ground, and secondary digestion is performed, so that the preparation efficiency is effectively improved.
