Calcium formate yog dab tsi?

Calcium formateyog calcium ntsev ntawm formic acid, nrog cov tshuaj formula Ca (HCOO)₂. Nws yog dawb, crystalline khoom uas yog soluble hauv dej. Nov yog cov ntsiab lus ntawm calcium formate:

Khoom:

• Chemical Formula: Ca(HCOO)₂
• Molar Mass: Kwv yees li 130.11 g / mol
• Cov tsos mob: Dawb crystalline hmoov los yog granules
• Solubility: Soluble hauv dej heev
• Qhov ceev: Kwv yees li 2.02 g / cm³
• Melting Point: Kwv yees li 300 ° C (decomposes)
• Tsis hnov ​​tsw: tsw ntxhiab

Kev tsim tawm:

• Calcium formate tuaj yeem tsim los ntawm cov tshuaj tiv thaiv nruab nrab ntawm calcium hydroxide (Ca(OH) ₂) lossis calcium oxide (CaO) thiab formic acid (HCOOH).
• Nws tseem tuaj yeem tau txais los ntawm cov khoom siv los ntawm cov tshuaj tiv thaiv ntawm calcium hydroxide thiab carbon monoxide.

Kev siv:

1. Kev lag luam kev tsim kho: Calcium formate feem ntau yog siv los ua ib qho ntxiv hauv cov cement thiab pob zeb formulations. Nws ua raws li lub accelerator, txhim kho lub zog thaum ntxov ntawm kev ua vaj tse thiab txo lub sijhawm teem sijhawm.
2. Tsiaj Pub Additive: Nws yog siv los ua zaub mov ntxiv rau cov tsiaj nyeg, tshwj xeeb tshaj yog nyob rau hauv cov khoom noj npua thiab nqaij qaib. Calcium formate ua hauj lwm raws li ib qhov chaw ntawm calcium thiab formic acid, uas yuav pab tau nyob rau hauv kev zom thiab txhim kho kev noj zaub mov.
3. Preservative: Calcium formate yog siv los ua preservative nyob rau hauv ntau yam kev lag luam, nrog rau cov khoom noj, tawv, thiab textiles, vim nws cov tshuaj tua kab mob.
4. Deicing Agent: Hauv qee thaj tsam, calcium formate yog siv los ua tus neeg sawv cev deicing rau txoj kev thiab kev taug kev, vim nws tuaj yeem txo qhov dej khov ntawm dej thiab tiv thaiv kev tsim dej khov.
5. Additive hauv Drilling Fluids: Hauv kev ua haujlwm roj thiab roj, calcium formate qee zaum ntxiv rau cov kua dej drilling los tswj rheology thiab txhim kho cov kua dej.
6. Tawv Tanning: Nws yog siv nyob rau hauv cov txheej txheem tawv tanning raws li tus neeg sawv cev npog los tswj pH thiab ua ib qho kev tiv thaiv kom tsis txhob o ntau dhau ntawm cov zais thaum ua.

Kev nyab xeeb:

• Calcium formate feem ntau suav hais tias muaj kev nyab xeeb rau nws txoj kev siv. Txawm li cas los xij, zoo li txhua yam tshuaj lom neeg, nws yuav tsum tau saib xyuas, thiab yuav tsum tau ua raws li kev tiv thaiv kev nyab xeeb tsim nyog.
• Kev noj los yog nqus tau cov calcium ntau ntau tuaj yeem ua rau khaus rau hauv plab lossis ua pa.
• Kev sib cuag ntawm daim tawv nqaij tuaj yeem ua rau khaus lossis ua xua rau cov tib neeg rhiab heev.

Environmental Impact:

• Calcium formate yog suav tias yog ib puag ncig tus phooj ywg, vim nws yog biodegradable thiab tsis nyob rau hauv ib puag ncig.
• Thaum siv los ua tus neeg sawv cev deicing, calcium formate tsis tshua muaj teeb meem rau cov nroj tsuag thiab dej hauv dej piv rau cov tshuaj chloride-based deicers.

calcium formate yog ntau yam tshuaj sib xyaw nrog ntau yam kev siv hauv kev lag luam, suav nrog hauv kev tsim kho, tsiaj pub, tshuaj tua kab mob, thiab cov tshuaj tua kab mob. Nws cov khoom ua rau nws muaj txiaj ntsig hauv kev txhim kho kev ua haujlwm ntawm cov ntaub ntawv thiab cov txheej txheem thoob plaws kev lag luam sib txawv.
