Calcium tsim cov txheej txheem ntau lawm

Calcium tsim yog tshuaj sib xyaw nrog cov qauv CA (HCOO) 2. Nws yog tsim los ntawm cov tshuaj tiv thaiv ntawm calcium hydroxide (Ca (Oh) 2) thiab formic acid (hcooh). Ntawm no yog ib tug dav dav dav dav ntawm cov txheej txheem ntau lawm rau calcium tsim:

1. Kev npaj ntawm calcium hydroxide:

• Calcium hydroxide, kuj tseem hu ua cov txiv qaub slaked, yog feem ntau tsim los ntawm cov dej ntawm cov dej khov (calcium oxide).
• Trylylime yog thawj zaug kub hauv ib lub kiln rau qhov kub kom tsav tawm cov roj carbon dioxide, uas ua rau tsim cov calcium oxide.
• Calcium oxide yog tom qab ntawd tov nrog dej hauv cov txheej txheem tswj los tsim cov calcium hydroxide.

2. Npaj ntawm formic acid:

• Formic acid feem ntau yog tsim los ntawm oxidation ntawm methani, siv cov catalyst xws li cov nyiaj catalyst lossis rhodium catalyst.
• Methanol yog refered nrog oxygen nyob hauv lub xub ntiag ntawm catalyst los tsim cov formic acid thiab dej.
• Cov tshuaj tiv thaiv yuav tau nqa tawm hauv lub nkoj reactor hauv qab tswj qhov kub thiab txias thiab cov xwm txheej siab.

3. Cov tshuaj tiv thaiv ntawm calcium hydroxide nrog formic acid:

• Nyob rau hauv cov hlab reensor, calcium hydroxide tov yog tov nrog formic acid daws hauv kev tsim cov calcium.
• Cov tshuaj tiv thaiv feem ntau yog exhericmic, thiab qhov kub yuav tswj tau kom ua kom zoo dua cov tshuaj tiv thaiv kab mob thiab tawm los.
• Cov calcium tsim tawm los ua cov khoom sib xyaw, thiab cov tshuaj tiv thaiv thiab cov tshuaj tiv thaiv kab mob yuav tau muab khi rau cov calcium teeb meem los ntawm cov theem ua kua.

4. Crystallization thiab kom qhuav:

• Cov calcium haum rau tau los ntawm cov tshuaj tiv thaiv yuav tau cov kauj ruam txuas ntxiv xws li crystallization thiab ziab kom tau txais cov khoom xav tau.
• Crystallization yuav ua tiav los ntawm txias cov tshuaj tiv thaiv lossis los ntawm kev ntxiv cov kuab tshuaj los txhawb cov siv lead ua kev tsim.
• Lub muaju ntawm calcium tsim yog tom qab ntawd cais tawm ntawm niam dej cawv thiab qhuav kom tshem tawm cov noo noo.

5. Purification thiab ntim:

• Daim qauv ci ci ntsa iab no yuav ua rau cov kauj ruam lim kom tshem tawm cov impurities thiab kom cov khoom lag luam zoo.
• Lub Lim Hauv Daim Qauv ua kom huv yog tom qab ntawd ntim rau hauv cov thawv ntim khoom tsim nyog lossis hnab ntim khoom cia, kev thauj mus los, thiab kev faib tawm kom cov neeg siv kom kawg.
• Kev tswj kev ua kom zoo tswj tau raug muab siv thoob plaws hauv cov txheej txheem ntau lawm los xyuas kom meej tias cov khoom kawg tau raws li cov kev qhia tshwj xeeb thiab kev tswj xyuas.

Kev tsim cov tshuaj calcium cuam tshuam nrog cov tshuaj tiv thaiv ntawm calcium hydroxide thiab formic acid los ua cov compound xav tau. Tus txheej txheem no yuav tsum ua tib zoo tswj cov tshuaj tiv thaiv kev ua, thiab cov kauj ruam kev ua kom tiav kom ua tiav cov khoom siv siab thiab tawm los. Calcium tsim yog siv nyob rau hauv ntau cov ntawv thov, suav nrog cov vaj tse additive, pub ntxiv, thiab hauv kev tsim cov tawv thiab textiles.
