Essentially,caustic soda and liquid caustic soda belong to the same category,except that one is a liquid and the other is a solid.Solids are common in the market,while liquids are not popular due to their low content,but they are cheaper than the price.
1、The difference between the two
1.Liquid alkali should be stored in polyethylene tanks and polyethylene tanks lined with steel;Soda flakes require plastic or kraft paper bags and need to be sealed.
2.Liquid alkali is liquid sodium hydroxide,also known as caustic soda or caustic soda.Due to different production processes in existing chlor alkali plants,the concentration of liquid alkali is usually 30-32%or 40-42%.Its characteristics are fast reaction rate,simple dosing,but difficult to control solubility,otherwise it is prone to crystallization at low temperatures.Dissolution of caustic soda is troublesome,but storage and transportation are convenient.
2、Similarity:Both are chemical raw materials,and customers with high alkaline requirements can choose flake alkali.
That's all for the content of this issue. In fact, whether it's caustic soda or alkaline solution, after purification, it can be divided into several levels according to different concentrations. Customers can choose according to their actual needs. Both are common in production, but due to their particularity, they should be stored separately and not confused.
