Mechanism of Action: The Alkali & Potassium Source
Kev ua haujlwm ntawm Potassium Carbonate stems los ntawm nws ob lub luag haujlwm ua tus muab kev pabcuamalkalinity (carbonate ions)thiabpoov tshuaj cations.
1. Alkaline Agent (Base): Hauv cov kev daws teeb meem aqueous, cov carbonate ion (CO₃²⁻) raug hydrolysis:
CO₃²⁻ + H₂O ⇌ HCO₃⁻ + OH⁻
Cov tshuaj tiv thaiv no tso tawm hydroxide ions (OH⁻), ua cov tshuajalkaline. Cov cuab yeej no yog siv los nruab nrab acids, kho pH, saponify rog (hauv xab npum ua), thiab ua raws li tus neeg sawv cev me me thaum ua ke nrog cov kua qaub.
2. Potassium Ion Pub: Raws li ib tug heev soluble poov tshuaj ntsev, nws zoo xa bioavailableK⁺ ions. Qhov no yog qhov tseem ceeb hauv kev ua liaj ua teb (cov chiv) thiab qee cov txheej txheem kev lag luam uas yuav tsum tau muaj cov poov tshuaj yam tsis muaj chloride lossis sulfate ions.
3. Fluxing Agent: Thaum qhov kub thiab txias (piv txwv li, hauv iav thiab ceramic ntau lawm), nws txo qis qhov melting point ntawm silica, ua kom yooj yim fusion thiab txhim kho cov khoom ntawm cov khoom kawg.
4. Tshuab ziab khaub ncaws: Nws muaj zog hygroscopic xwm tso cai rau nws nqus dej los ntawm cov organic solvents los yog gases thaum siv los ua desiccant.

FAQ: Cov lus nug nquag nug
Q: Dab tsi yog qhov txawv ntawm Potassium Carbonate (K₂CO₃) thiab Potassium Bicarbonate (KHCO₃)?
A: K₂CO₃ (potassium carbonate) yog lub hauv paus muaj zog thiab muaj ob lub poov tshuaj ions ib carbonate. KHCO₃ (potassium bicarbonate) yog lub hauv paus me me (bicarbonate) thiab muaj ib qho poov tshuaj ion. Lawv tsis ncaj qha interchangeable nyob rau hauv formulations.
Q: Kuv tuaj yeem nrhiav Daim Ntawv Qhia Txog Kev Nyab Xeeb (SDS/MSDS) rau qhov twg?
A: Daim Ntawv Qhia Kev Nyab Xeeb Kev Nyab Xeeb (SDS) ib txwm muab los ntawm tus neeg muag khoom thaum yuav khoom thiab muaj nyob rau ntawm kev thov. Nws muaj cov ncauj lus kom ntxaws txog kev phom sij, tuav, pov tseg, thiab cov ntaub ntawv tswj hwm.
Q: Puas yog Potassium Carbonate zaub mov qib?
A: Yog lawm, zaub mov- qib Potassium Carbonate yog tsim los ua kom tau raws li cov qauv kev coj dawb huv (xws li FCC, E501). Nws tau pom zoo siv los ua zaub mov ntxiv (acidity regulator, stabilizer). Nco ntsoov qhia "qib zaub mov" thaum xaj rau cov ntawv thov no.
Q: Vim li cas nws thiaj li tseem ceeb kom khaws nws kaw?
A: Potassium Carbonate yog hygroscopic heev. Nws absorbs dej los ntawm huab cua, ua ntub dej, clumpy, thiab thaum kawg hloov mus rau potassium bicarbonate, uas hloov nws qhov hnyav, potency, thiab kev ua haujlwm.
Q: Dab tsi yog cov kev xaiv ntim khoom?
A: Nws feem ntau muaj nyob rau hauv cov dej noo- cov hnab pov thawj (piv txwv li, 25 kg rau kev lag luam siv), nruas, lossis me me ntim cov fwj thiab cov hnab ntim rau kev siv (piv txwv li, 500g, 1kg).
