Calcium chloride yog ntsev tsim los ntawm chloride ions thiab calcium ions. Anhydre calcium muaj zog nqus nqus tau, siv ua ib qho desiccant rau ntau yam tshuaj, av improve, cov dej num lim dej, muab tshuaj txhuam tus neeg saib xyuas. Nws yog qhov siv tshuaj lom neeg siv dav dav, cov khoom siv raw, cov khoom noj ntxiv, pub roj ntxiv thiab cov ntaub ntawv raw rau kev tsim cov hlau roj calcium.
Lub cev cov khoom ntawm calcium chloride
Calcium chloride yog tsis muaj xim crystal crystal, dawb lossis off-dawb, goodcompb thaiv, spheroid, hmoov av, hmoov. Melting taw tes 782 ° C, ntom ntom 1.086 g / ml ntawm 20 ° C, npau tes boil 1600 ° C, Dej Solubility 740 g / l. Me ntsis toxic, tsw ntxhiab, iab iab saj. Cov hygroscopic thiab yooj yim thaum raug huab cua.
Yooj yim soluble hauv dej, thaum tso ntau npaum li cas ntawm cov cua sov (calcium chloride fromholgy of -176.2cal / g), nws cov kua a aqueous yog me ntsis acidic. Soluble hauv dej cawv, acetone, acetic acid. Rov qab los nrog ammonia los yog ethanol, CaclxHNH3 thiab CaclatAHoo · 4C1h5oh complexes tau tsim, ntsig txog. Ntawm qhov kub tsawg, cov tshuaj crystallizes thiab precipitates li ib tug hexahydrate, thiab maj mam dhau los ua 260 ° C, uas dhau los ua ib qho dawb dhau los ua cov tshuaj dawb ailous calcium chloride.
Anhydrous calcium chloride
1, lub cev nqaij daim tawv thiab tshuaj lom neeg: tsis muaj xim crystal, dawb lossis tawm-dawb ntxeem tau thaiv lossis pob zeb dawb. Cov txheeb ze ceev yog 2.15, lub ntsiab lus melting yog 782 ℃, kev npau taws me me, tsis muaj pa dej, soluble hauv cawv, acrylic vinegar, acetic acid.
2, Kev Siv Khoom Siv: Nws yog tus neeg sawv cev nag lossis daus rau kev tsim cov xim pas dej pigments. Kev tsim cov nitrogen, acetylene roj, hydrogen chloride, oxygen thiab lwm yam roj desiccant. Cawv, cov neeg phem, Esters thiab Acrylic resins tau siv los ua cov neeg sawv cev, thiab lawv cov kev daws teeb meem aquees yog cov tub yees rau tub yees thiab tub yees. Nws tuaj yeem ua kom nrawm nrawm ntawm cov pob zeb ua, nce cov khaub noom txias ntawm cov xis cug, thiab yog cov tshuaj tiv thaiv kab mob zoo tshaj plaws. Siv los ua tus sawv cev tiv thaiv rau txhuas cov hlau nplaum me me, ua kom tus neeg sawv cev.
Fleacium calcium chloride
1, lub cev nqaij daim tawv thiab tshuaj lom neeg: tsis muaj kob, cov khoom no yog dawb, tawm-dawb siv lead. Iab saj, muaj zog deliquescent.
Nws tus txheeb ze ceev yog 0.835, yooj yim soluble hauv dej, nws lub auroous nyob rau ether, thiab lub cev qhuav dej rau hauv cov teeb meem anhydous thaum rhuab rau 260 ℃. Lwm yam tshuaj lom neeg tau zoo ib yam li cov tshuaj calhydrous calcium.
2, Muaj nuj nqi thiab siv: Fleake calcium chloride siv ua lub teb; Cov tshuaj tiv thaiv kab mob; Molten dej khov lossis daus; Nplaim taws retardants rau cov ntaub thiab cov ntaub qhwv cov ntaub qhwv cov ntaub qhwv; Cov tshuaj txuag ntoo; Roj Hmab Ntau Lawm raws li tus neeg sawv cev folding; Sib xyaw cov hmoov txhuv nplej siab yog siv los ua tus neeg sawv cev.
Calcium Chloride aque kua
Calcium chloride tov muaj cov yam ntxwv ntawm kev ua haujlwm, qis dua qhov taw tes khov kho, thiab muaj kev sib chwv cua sov tuaj yeem siv ntau yam kev lag luam thiab chaw muaj kev lag luam.
Lub luag haujlwm ntawm calcium tshuaj daws teeb meem:
1. Alkaline: calcium ion hydrolysis yog alkaline, thiab hydrogen chloride yog volatile a ion hydrolysis.
2, kev cob qhia: muaj ions hauv qhov kev daws teeb meem uas tuaj yeem txav dawb.
3, kom khov taw tes: calcium chloride daws qhov taw tes khov khov yog qis dua li dej.
4, Kev npau npau: Calcium Chloride aque kua kub boiling point yog siab dua li dej.
5, evaporation crystallization: calcium chloride aqueous kua evaporization los nyob rau hauv ib qho chaw muaj hydrogen chloride.
Desiccant
Calcium chloride tuaj yeem siv los ua tus neeg sawv cev lossis lub cev qhuav dej rau roj av thiab roj organic. Txawm li cas los xij, nws tsis tuaj yeem siv los ua kom ethanol thiab ammonia, vim tias ethanol thiab ammonia ua rau haus dej haus cawv Cacl2C2h5o Anhydre calcium kuj tseem tuaj yeem ua rau hauv tsev neeg cov neeg sawv cev ua haujlwm tau pom zoo los ntawm FDA nqus tus neeg sawv cev, nws lub luag haujlwm yog kom ntseeg tau tias qhov txhab.
Vim tias calcium chloride yog qhov nruab nrab, nws tuaj yeem qhuav cov kua qaub lossis cov pa roj alkalgen, orgygen, olirocide, nitrogen dioxide, etc., thaum qhuav cov roj av. Cov tshuaj nplaum muaj feem ntau yog siv los ua tus desiccant los sau cov hmoov av qhuav, thiab cov ntug dej hiav txwv kom qhuav (lossis cov ntug dej caw qhuav tuaj yeem siv rau kev tsim cov dej qab zib. Qee tsev neeg dehumidifiers siv calcium chloride kom nqus noo noo ntawm huab cua.
Lub anhydrous calcium yog kis rau ntawm cov xuab zeb saum npoo av, thiab cov av noo kom haum rau cov av ntub, yog li los tswj cov hmoov av ntawm txoj kev.
Tshuav tshuaj saib xyuas tus neeg sawv cev thiab dej txias
Calcium chloride tuaj yeem txo cov dej khov ntawm cov dej, thiab cov dej qab zib tuaj yeem tiv thaiv cov av thiab nroj tsuag kom puas. Calcium tshuaj chloride tov kuj tseem tuaj yeem sib xyaw nrog cov dej khov qhuav los npaj cov dej khov kho cryogenic txias. Lo dej khov qhuav yog ntxiv rau cov kev daws teeb meem hauv cov kab hauv cov khoom siv kom txog thaum dej khov. Lub qhov kub ruaj khov ntawm cov dej txias txias tuaj yeem tswj tau los ntawm ntau hom thiab ntau cov ntsev daws. Calcium cov tshuaj calcium feem ntau siv raws li cov ntsev raw, thiab cov tshuaj muaj zog yog li cas, tab sis kuj yog qhov ntsuas hluav taws xob ntxiv yog los ntawm 0 ° C rau -51 ° C. Cov qauv no tuaj yeem pom tau nyob rau hauv lub fwar fwj nrog cov khoom siv rwb tau xav tau, thiab ntau yam ntsev yuav tsum tau npaj, qhov ntsuas kub kuj tseem nyob ruaj khov.
Raws li qhov chaw ntawm calcium ions
Ntxiv cov tshuaj pleev xim calcium mus rau pas dej da dej tuaj yeem ua rau cov pas dej pho tsis zoo thiab nce kev tawv ntawm cov yaig ntawm cov phab ntsa qhob. Raws li Le Conteleier lub hauv paus ntsiab lus thiab cov asionic cov nyhuv, nce siab ntawm cov calcium ions hauv pas dej calcium sib xyaw uas yog qhov tseem ceeb rau cov qauv pob zeb.
Ntxiv cov tshuaj calcium mus rau cov dej ntawm cov roj ntsha tub rog ua rau muaj cov roj ntsha roj hauv dej thoob dej yug ntses siv nws los ua cov calcium carbonate shells. Txawm hais tias calcium hydroxide lossis ntau cov calcium reactor tuaj yeem ua tiav tib lub hom phiaj, ntxiv cov qauv calcium yog qhov cuam tshuam ceev tshaj plaws thiab muaj qhov tsawg tshaj plaws ntawm cov dej.
Calcium chloride rau lwm yam kev siv
Qhov kev ua tiav thiab exothermic xwm ntawm calcium chloride ua rau nws siv nyob rau hauv tus kheej cua kub cov kaus poom thiab cua sov.
Calcium chloride tuaj yeem pab tswj kom ceev rau qhov chaw pib hauv cov pob zeb, tab sis chloride ions tuaj yeem ua rau corrosion ntawm cov hlau nplaum, yog li cov tshuaj calcium tsis tuaj yeem siv hauv kev txhawb nqa. Anhydrus calcium chloride tuaj yeem muab qee qib ntawm noo noo rau pob zeb vim tias nws hygroscopic zog.
Nyob rau hauv kev lag luam roj av, calcium chloride yog siv los ua kom muaj qhov ntom ntom-dawb brine, thiab tseem tuaj yeem muab ntxiv rau lub aqueous drilling cov kev nthuav dav ntawm av nplaum. Nws yog siv los ua flux kom txo qis qhov melting taw tes nyob rau hauv cov txheej txheem ntawm kev tsim cov sodium hlau los ntawm electrolytic melting ntawm cov txheej txheem tiv thaiv Davy sodium. Thaum ceramics yog tsim, calcium chloride yog siv los ua ib qho ntawm cov khoom siv cov lus qhia kom raug tshem tawm yooj yim rau siv thaum grouting.
Calcium Chloride tseem yog cov kev ntxiv hauv plastics thiab cov khoom siv hluav taws xob, raws li kev ntxiv hauv cov tshuaj tiv thaiv kom tsis txhob muaj kev tiv thaiv kom tsis txhob muaj kev sib haum xeeb, thiab raws li kev ua haujlwm rau hauv cov ntaub softeners.
