Sodium hydroxide is one of the most damaging alkalis to the skin among alkaline substances, known as caustic soda, which has strong corrosive properties and irritation. It has a certain deliquescence and is easy to absorb water vapor from the air.
In addition to making corresponding reagents, due to its strong water absorption and deliquescence, it can also be used as an alkaline desiccant, while also absorbing certain acidic gases. The characteristics of sodium hydroxide determine that this type of product is an indispensable and important substance in a large number of chemical reactions. Sodium hydroxide is an important material for producing various substances such as polycarbonate, super absorbent polymers, and zeolites.
Sodium hydroxide is widely used in water treatment. In sewage treatment plants, sodium hydroxide can reduce the hardness of water through neutralization reactions. In the industrial field, it is a regenerant for ion exchange resin regeneration. Sodium hydroxide has strong alkalinity and relatively high solubility in water. Due to its liquid nature, caustic soda is easy to measure and can be conveniently used in various fields of water treatment.
