Potassium carbonate Usage
1. Potassium carbonate can be used to produce optical glass, which can improve the transparency, strength and refractive index of glass. 2. It is also used in the production of welding rods to prevent arc breaks during welding.
3. Used in the production of vat dyes and the whitening of printing and dyeing and ice dyeing.
4. Used as an adsorbent for removing hydrogen sulfide and carbon dioxide.
5. Potassium carbonate mixed with soda ash can be used as dry powder fire extinguishing agent.
6. It can also be used as an auxiliary raw material in the production of alcohol and as an anti-aging agent in rubber production.
7. It is also used in the production of ink, photographic medicine Chemicalbook, polyester, medicine, electroplating, tanning, ceramics, building materials, crystal, potassium soap and medicine.
8. Heavy potassium carbonate is mainly used as the raw material of picture tube glass bulb, widely used in glass and special glass raw materials, and used for decarbonization of large chemical fertilizers.
9. It can be used as leavening agent in food.
10. As an alkaline agent and dough improver, and can inhibit noodles from souring, it can be used in flour-made foods, and it can be used in moderation according to production needs.
11. Used in the processing of exposed photosensitive materials.
12. Fluxes for analytical reagents, reference reagents, molten silicates and insoluble sulfates.
