说明

氢氧化钙通常用于废水处理厂(WWTP)来调节pH值。氢氧化钙由于其强大的基本特性而具有许多应用。用途包括水和污水处理中的絮凝剂,粉刷成分,土壤改良,作为非碱液头发松弛剂中的碱液替代品,以及在石灰工业中中和酸。

一般描述

Calcium hydroxide is commonly used in wastewater treatment plants (WWTPs) to adjust pH. Calcium hydroxide has numerous applications due to its strong basic characteristics. Uses include flocculants in water and sewage treatment, a whitewash ingredient, soil improvement, as a lye substitute in non-lye hair relaxers, and in the liming industry to neutralize the acid.
 

应用

Calcium hydroxide can be used:
  • In the pretreatment of technical lignin during the pyrolysis in a fluidized bed reactor to overcome the agglomeration to produce phenolic-rich bio-oil.
  • As a catalyst in the pyrolysis of pinewood in a fixed bed reactor.
