Dab tsi yog anhydrous calcium chloride?

Anhydrous calcium chlorideYog cov tshuaj sib txuas nrog cov mis cacl₂, thiab nws yog hom calcium ntsev. Lo lus "anhydous" qhia tias nws yog devoid ntawm dej lwg me me. Qhov no ua ke yog hygroscopic, lub ntsiab lus nws muaj kev muaj zog muaj zog rau dej thiab kom yooj yim nqus dej los ntawm ib puag ncig ib puag ncig.

Cov qauv tshuaj ntawm cov tshuaj me me ntawm cov tshuaj muaj dej hauv calhacide muaj ib calcium (ca) atom thiab ob chlorine (cl) atoms. Nws yog ib qho dawb, crystalline khoom ntawm chav sov, tab sis nws cov tsos tuaj yeem sib txawv raws li qib ntawm kev coj dawb huv. Ib qho ntawm cov khoom lag luam uas tsis muaj peev xwm ntawm cov tshuaj anhydrous calhium chloride yog nws lub peev xwm los tsim cov duab sib txuas nrog cov dej lwg me, ua rau nws muaj txiaj ntsig hauv ntau yam kev siv.

Anhydrus calcium chloride yog cov lag luam tsim los ntawm cov kev tawm tsam ntawm calcium carbonate (caco₃) nrog hydrochloric acid (HCl). Kev siv tshuaj rau cov txheej txheem no yog:

Caco₃ + 2HCl → Cacl₂ + CO₂ + H₂o

Cov khoom lag luam uas muaj txiaj ntsig, anhydrus calcium chloride, yog tom qab ntawd ua tib zoo ua tiav kom tshem tawm cov ntsiab lus dej ntxiv. Tsis muaj dej lwg me me ua rau nws muaj ntau yam sib xyaw nrog ntau cov kev siv tseem ceeb thoob plaws kev lag luam.

Ib qho ntawm thawj daim ntawv thov ntawm anhydre calcium chloride yog ib tus neeg tsis txaus ntseeg lossis tus neeg saib xyuas kom qhuav. Vim tias nws hygroscopic xwm, nws zoo nqus dej vapor los ntawm huab cua, ua rau nws muaj kev puas tsuaj rau cov khoom lag luam ntau yam, suav nrog cov khoom lag luam, hluav taws xob.

Ntxiv rau nws lub luag haujlwm ua tus desiccant, anhydrous calcium chloride yog dav siv nyob rau hauv apping app. Thaum kis ntawm cov dej khov lossis daus los daus, nws lowers qhov khov ntawm cov dej, ua rau yaj ntawm dej khov thiab daus. Qhov no ua rau nws muaj cov khoom xyaw uas nquag siv rau kev ua kom muaj kev nyab xeeb rau kev nyab xeeb lub caij ntuj no los ntawm kev tiv thaiv kev tsim cov dej khov ntawm txoj kev tsheb.

Anhydre calcium Chloride tseem nrhiav daim ntawv thov hauv kev lag luam khoom noj ua cov neeg sawv cev ruaj khov rau cov txiv hmab txiv ntoo thiab zaub. Nws pab tswj kev ntxhib los mos ntawm cov khoom pishible thaum lub sij hawm ua thiab chaw cia khoom. Ntxiv mus, nws tau siv nyob rau hauv cov roj thiab roj kev lag luam rau kev ua dej kom zoo thiab ua tiav, ua haujlwm ua cov quav qhuav los tiv thaiv kom tiv thaiv cov av nplaum.

Txawm hais tias nws cov ntawv thov muaj ntau yam, cov tshuaj muaj ntau yam tshuaj, muaj lub ntsej muag muaj mob calcium yuav tsum tau ua tib zoo saib xyuas, raws li nws tuaj yeem ua rau voos rau ntawm daim tawv nqaij thiab qhov muag. Kev ceev faj kev nyab xeeb kev nyab xeeb, nrog rau kev siv hnab looj tes xws li hnab looj tes thiab goggles, yog qhov tseem ceeb thaum ua haujlwm nrog cov compound no.

Hauv kev xaus, kev xaus calcium chloride yog qhov tseem ceeb rau kev siv tshuaj lom neeg muaj ntau cov ntawv thov vim nws hygroscopic xwm. Los ntawm kev tiv thaiv noo noo kev puas tsuaj rau kev pabcuam raws li de-icing tus neeg sawv cev, qhov sib xyaw no ua rau nws cov versatility thiab qhov tseem ceeb hauv cov ntawv thov niaj hnub no.
