As we all know, potassium hydroxide is a white powder and a toxic alkali. The chemical property is unstable. It will absorb carbon dioxide in the air at room temperature. Chemical reaction occurs, and a large amount of heat is released in contact with water.
It is widely used in electrochemistry, textile, light industry, medicine and other fields. Specifically:
Electrochemistry: LCD, crystal cleaner, etching, electroplating, battery production
Light industry: production of potassium soap and cosmetics (such as cold cream, snow cream and shampoo);
Textile industry: printing and dyeing, bleaching, mercerizing, widely used as the main raw material for the manufacture of man-made fibers and polyester fibers;
Medicine: used to produce potassium borohydride, progesterone, vanillin, spironolactone, saparinol, testosterone propionate, etc;
Others: used for metallurgical heating agent and leather degreasing.
Wet electronic chemicals: as a wet electronic chemical, potassium hydroxide is widely used in electronics, semiconductor, medicine and cosmetics industries, especially in wafer processing, high-end industrial PCB (printed circuit), LCD manufacturing and other industries.
At present, the global manufacturers engaged in the R & D and large-scale production of wet electronic chemicals are mainly concentrated in the United States, Germany, Japan, South Korea, Taiwan and other regions. The application prospect of grade I potassium hydroxide will be more broad.
New fertilizer field: as the key raw material of potassium fertilizer, potassium hydroxide is widely used in the field of chemical fertilizer.
The state has put forward the development policy of "reducing time and increasing efficiency", and the fertilizer industry is facing transformation and upgrading. Slow and controlled release fertilizers, water-soluble fertilizers (such as potassium carbonate, potassium dihydrogen phosphate, potassium humate) and other new fertilizers are accurate, convenient, environmentally friendly, pollution-free and have high absorption rate.
In the field of food additives: potassium hydroxide is one of the common food additives, which mainly plays a role in adjusting the pH value of food and maintaining the properties and shape of food.
With the growth of population and the improvement of national income, the output and income of food additives in China are growing steadily, and will develop in a more refined direction in the future. High end food grade potassium hydroxide will usher in growth opportunities with the upgrading and development of the food industry.
