Uses
- Chemical production: Potassium hydroxide is an important basic raw material in the field of chemical industry. It is used in large quantities for the production of potassium salts, such as potassium carbonate, potassium phosphate and so on. In the pharmaceutical industry, it is used as intermediates for synthesising certain drugs.
- Surface treatment: In metal surface treatment, it can be used in degreasing treatment of metal. In the surface treatment of aluminium products, potassium hydroxide solution can be used in etching process.
- Other industries: In the textile industry, potassium hydroxide is used in mercerising cotton fabrics, which can improve the dyeing performance. In the food industry, it can be used as an acidity regulator to adjust the pH value of foodstuffs; it can also be used in the production of food wrapping paper to improve its water resistance and strength by treating the paper.
