Anhydrous Calcium Chloride yog dab tsi?

Calcium Chloride Anhydrousyog cov tshuaj sib xyaw nrog cov mis CaCl₂, thiab nws yog hom calcium ntsev.Lo lus "anhydrous" qhia tias nws tsis muaj dej molecules.Qhov sib xyaw no yog hygroscopic, txhais tau tias nws muaj kev sib raug zoo rau cov dej thiab yooj yim nqus dej los ntawm ib puag ncig ib puag ncig.

Cov qauv tshuaj ntawm anhydrous calcium chloride muaj ib qho calcium (Ca) atom thiab ob chlorine (Cl) atoms.Nws yog dawb, crystalline khoom nyob rau hauv chav tsev kub, tab sis nws cov tsos yuav txawv nyob ntawm seb lub degree ntawm purity.Ib qho ntawm cov khoom tseem ceeb ntawm anhydrous calcium chloride yog nws lub peev xwm los tsim cov hydrated compounds nrog dej molecules, ua rau nws muaj txiaj ntsig hauv ntau yam kev siv.

Anhydrous calcium chloride yog ua lag luam los ntawm cov tshuaj tiv thaiv ntawm calcium carbonate (CaCO₃) nrog hydrochloric acid (HCl).Kev sib npaug tshuaj rau cov txheej txheem no yog:

CaCO₃ + 2HCl → CaCl₂ + CO₂ + H₂O

Cov khoom uas tshwm sim, anhydrous calcium chloride, yog tom qab ntawd ua tib zoo ua kom tshem tawm cov ntsiab lus dej ntxiv.Qhov tsis muaj dej molecules ua rau nws muaj ntau yam sib xyaw nrog ntau yam tseem ceeb siv thoob plaws kev lag luam sib txawv.

Ib qho ntawm thawj daim ntawv thov ntawm anhydrous calcium chloride yog ua desiccant los yog ziab tus neeg sawv cev.Vim nws qhov xwm txheej hygroscopic, nws zoo nqus dej vapor los ntawm huab cua, ua rau nws muaj txiaj ntsig los tiv thaiv kev puas tsuaj rau ntau yam khoom, suav nrog cov khoom ntim, khoom siv hluav taws xob, thiab tshuaj lom neeg.

Ntxiv rau nws lub luag haujlwm ua desiccant, anhydrous calcium chloride yog dav siv hauv de-icing daim ntaub ntawv.Thaum kis tau rau ntawm cov dej khov lossis daus, nws txo qis qhov dej khov ntawm dej, ua rau cov dej khov thiab cov daus yaj yaj.Qhov no ua rau nws yog ib qho khoom muaj nyob rau hauv txoj kev ntsev formulations siv los txhim kho lub caij ntuj no txoj kev nyab xeeb los ntawm kev tiv thaiv kev tsim cov dej khov ntawm txoj kev.

Anhydrous calcium chloride kuj pom daim ntawv thov hauv kev lag luam zaub mov ua tus neeg sawv cev rau cov txiv hmab txiv ntoo thiab zaub.Nws pab tswj qhov kev ntxhib los mos ntawm cov khoom puas tsuaj no thaum ua thiab khaws cia.Ntxiv mus, nws yog siv nyob rau hauv cov roj thiab roj kev lag luam rau zoo drilling thiab tiav cov kua, ua hauj lwm raws li ib tug dehydrating neeg sawv cev los tiv thaiv qhov o ntawm av nplaum formations.

Txawm hais tias nws muaj ntau yam kev siv, anhydrous calcium chloride yuav tsum tau saib xyuas, vim nws tuaj yeem ua rau tawv nqaij thiab qhov muag.Kev tiv thaiv kev nyab xeeb kom raug, suav nrog kev siv cov iav tiv thaiv xws li hnab looj tes thiab tsom iav, yog qhov tseem ceeb thaum ua haujlwm nrog cov khoom siv no.

Nyob rau hauv xaus, anhydrous calcium chloride yog ib qho tseem ceeb tshuaj compound nrog ntau yam kev siv vim nws hygroscopic xwm.Los ntawm kev tiv thaiv ya raws kev puas tsuaj los ua tus neeg sawv cev de-icing, qhov sib xyaw ua ke no ua lub luag haujlwm tseem ceeb hauv ntau yam kev lag luam, qhia txog nws cov kev siv ntau yam thiab qhov tseem ceeb hauv kev siv niaj hnub no.
