2. It is also used in the production of welding rods, which can prevent the arc breaking phenomenon during welding.
3. Used for the production of VAT dyes and their dyeing and ice bleaching.
4. Used as an adsorbent to remove 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 for acetone and alcohol production and as an antioxidant in rubber production.
7. Chemical potassium carbonate aqueous solution can be used for cooking cotton cloth and degreasing wool.
8. It is also used in the production of ink, photo medicine, polyester, medicine, electroplating, leather, ceramics, building materials, crystal, potash soap and medicine.
9. Heavy potassium carbonate is mainly used as raw materials for picture tube glass shells, widely used as raw materials for glass and special glass, and used for decarbonization of large fertilizers.
10. It can be used as a leavening agent in food.
11. As an alkaline agent and dough improver, and can inhibit the acid of noodles, can be used for noodle food, according to the production needs of appropriate use.
12. Used for washing and processing of exposed photosensitive materials.
13. For analytical reagents, reference reagents and fluxes of molten silicates and insoluble sulfates.
