Method for hydrothermally synthesizing tobermorite by using waste glass
The invention relates to the technical field of tobermorite synthesis, in particular to a method for hydrothermally synthesizing tobermorite by using waste glass, which comprises the following steps: crushing waste glass solid waste to obtain waste glass fragments, and crushing the crushed waste glass fragments to obtain waste glass powder; screening the waste glass powder to obtain micron-sized glass powder; the preparation method comprises the following steps: dispersing and mixing micron-sized glass powder into a sodium hydroxide solution, and uniformly stirring by using a high-speed stirrer to obtain a stable precursor solution; putting the precursor solution into a hydrothermal reaction kettle for hydrothermal reaction; after the reaction is finished, cooling reaction slurry to room temperature, and then carrying out suction filtration, washing and filtration on the solution to remove impurities; and carrying out constant-temperature crystallization reaction on the reaction slurry from which the impurities are filtered out to obtain tobermorite crystals. The preparation method disclosed by the invention is more simplified, and is beneficial to improving the production efficiency and reducing the manufacturing cost.
本发明涉及托贝莫来石合成技术领域，具体涉及一种利用废玻璃水热合成托贝莫来石的方法，包括以下步骤：将废玻璃固废进行破碎处理得到废玻璃碎块，破碎处理后对废玻璃碎块进行粉碎处理得到废玻璃粉体；将废玻璃粉体进行筛分，得到微米级玻璃粉；将微米级玻璃粉分散混合到氢氧化钠溶液中，使用高速搅拌器搅拌均匀，得到稳定的前驱体溶液；将前驱体溶液置于水热反应釜中进行水热反应；反应结束后，将反应浆料冷却至室温，然后将溶液进行抽滤洗涤过滤，滤除杂质；将滤除杂质后的反应浆料进行恒温晶化反应，得到托贝莫来石晶体。本发明的制备方法更加简化，有助于提高生产效率和降低制造成本。
