Potassium Carbonate CAS 584-08-7
Potassium carbonate (cov tshuaj formula: K2CO3, Lus Askiv Potassiumcarbonate), los yog potash, zoo li tsis muaj xim siv lead ua los yog dawb hais, yooj yim soluble hauv dej, nws cov tshuaj muaj zog alkaline. Thaum cov saturated aqueous tov tau txias, 2K2CO3·3H2O ntawm cov iav monoclinic crystal hydrate crystallized tawm nrog ib tug ceev ntawm 2.043, thiab cov siv lead ua dej poob ntawm 100 ℃. Insoluble hauv ethanol, acetone thiab ether. Hygroscopic, raug rau huab cua tuaj yeem nqus cov pa roj carbon dioxide thiab dej, mus rau hauv potassium bicarbonate.

1. Potassium carbonate tuaj yeem siv los tsim cov iav kho qhov muag, uas tuaj yeem txhim kho cov pob tshab, lub zog thiab refractive coefficient ntawm iav.
2. Kuj tseem siv rau hauv kev tsim cov vuam pas nrig, tuaj yeem tiv thaiv qhov tshwm sim ntawm arc tawg thaum vuam. 3. Siv rau kev tsim khoom ntawm VAT dyes, dyeing thiab whitening ntawm cov dej khov dyeing.
4. Siv los ua ib qho adsorbent tshem tawm hydrogen sulfide thiab carbon dioxide.
5. Potassium carbonate tov nrog soda tshauv tuaj yeem siv los ua cov hmoov qhuav qhuav.
6. Nws kuj tuaj yeem siv los ua cov khoom siv raw rau acetone thiab cawv ntau lawm thiab antioxidant hauv cov roj hmab ntau lawm.
7. Potassium carbonate aqueous tov yuav siv tau rau ua noj ua haus paj rwb thiab degreasing ntaub plaub.
8. Kuj tseem siv tau rau luam ntawv number case, yees duab tshuaj, polyester, tshuaj, electroplating, tawv, ceramics, tsev ntaub ntawv, siv lead ua, potash xab npum thiab tshuaj ntau lawm.
