Preparation process of nanoscale anti-condensation calcium hydroxide
The invention belongs to the technical field of nano material preparation, mainly relates to calcium hydroxide, and particularly relates to a preparation process of nano-scale anti-condensation calcium hydroxide. The nano-scale anti-condensation calcium hydroxide is prepared mainly through a sol-gel method, specifically, nano-scale sol is formed through hydrolysis and condensation reaction of a precursor, and nano-particles are obtained through drying and heat treatment. The nanoscale calcium hydroxide is good in anti-condensation effect, the nanoscale calcium hydroxide shows excellent dispersity and reaction activity due to the small-size effect and the high specific surface area, the cavitation effect of ultrasonic waves is utilized in the process of preparing the nanoscale calcium hydroxide, Van der Waals force among particles is destroyed, and agglomeration is prevented.
本发明属于纳米材料制备技术领域,主要为一种氢氧化钙,具体涉及一种纳米级抗凝结氢氧化钙的制备工艺。主要通过溶胶‑凝胶法制备纳米级抗凝结氢氧化钙,具体为通过前驱体的水解和缩合反应,形成纳米级的溶胶,再通过干燥和热处理得到纳米颗粒。本发明所述的纳米级氢氧化钙抗凝结效果好,纳米级氢氧化钙由于其小尺寸效应和高比表面积,表现出优异的分散性和反应活性,在制备纳米级氢氧化钙过程中利用超声波的空化效应,破坏颗粒间的范德华力,防止团聚。
