Lime modifier for delaying rapid quicklime digestion and method thereof, modified quicklime, autoclaved aerated concrete block and preparation method thereof
The invention discloses a lime modifier for delaying rapid quicklime digestion and a method thereof, modified quicklime, an autoclaved aerated concrete block and a preparation method thereof, the raw material formula of the modifier comprises triethanolamine and water, and the mass part ratio of triethanolamine to water is 1: (10-500). According to the lime modifier and the method thereof, the quick lime is adjusted, the reaction speed after the quick lime makes contact with water is decreased, the digestion speed of the quick lime is increased, the modified quick lime is obtained, the content of A-CaO in the modified quick lime is relatively low, and the price of the modified quick lime is lower than that of medium-speed quick lime; the modified quicklime is stably digested, so that the effect of prolonging the digestion of the quicklime is achieved, the mutual adaptation of the slurry thickening speed and the aluminum powder gas-forming speed in the production of the autoclaved aerated concrete blocks is favorably ensured, the production process of the autoclaved aerated concrete blocks is stabilized, the production quality can be stably controlled, and the product qualification rate is improved.
本发明公开了一种延缓快速生石灰消解的石灰改性剂、方法、改性生石灰、蒸压加气混凝土砌块及其制备方法，改性剂的原料配方包括：三乙醇胺和水，三乙醇胺与水的质量份数比为1：(10～500)。本实施例中的延缓快速生石灰消解的石灰改性剂及方法，对快速生石灰进行调节，延缓快速生石灰与水接触后发生反应的速度，使得快速生石灰的消解速度延长，得到改性生石灰，改性生石灰中的A‑CaO含量相对较低，且价格相对中速生石灰低，改性生石灰消解平稳达到延长快速生石灰消解的效果，利于在蒸压加气混凝土砌块生产中保证料浆稠化速度与铝粉发气速度的相互适应，稳定了蒸压加气混凝土砌块的生产工艺，能够平稳控制生产质量，提升产品合格率。
