Nta. A calcium chloride ziab cev muaj calcium chloride pellets nyob rau sab saum toj thiab hauv qab, tuav nyob rau hauv qhov chaw los ntawm plugs ua los ntawm iav ntaub plaub. Raws li huab cua ntws los ntawm cov ntaub plaub thiab cov calcium chloride , nws yog de-humidified kom cov huab cua nkag mus rau hauv cov tshuaj tiv thaiv chamber muaj me me los yog nomoisture.
Tsis tas li ntawd, calcium chloride puas tsim kev puas tsuaj rau tib neeg lub cev?
Yog tias noj, calcium chloride tuaj yeem ua rau kub hnyiab hauv qhov ncauj thiab caj pas, nqhis dej ntau dhau, ntuav, mob plab, qis ntshav siab, thiab lwm yam ua rau mob hnyav. Nyob rau hauv cov xwm txheej hnyav ntawm kev kis lossis kev noj, cov tshuaj no tuaj yeem ua rau tawv nqaij kub hnyiab, mob plawv, teeb meem ua pa, thiab qaug dab peg.
Qhov thib ob, calcium chloride yog dab tsi hauv cov zaub mov? Calcium chloride (CaCl2) yog siv nyob rau hauv ntau yam ntawm zaub mov cov khoom xws li cheese, taum pauv, thiab cov dej haus ua kis las vim nws cov txiaj ntsig ua tus neeg sawv cev tiv thaiv kab mob, stabilizer, thiab thickener. Calcium chloride tuaj yeem siv los hloov kho rau cov ntxhia tsis txaus thaum lub sijhawm ua cheese lossis txawm tias thaum npias brewing.
Tsis tas li ntawd, kev siv lub guard tube yog dab tsi?
Ua kom qhuav cev los yog tub tiv thaiv yog a cev -zoo li daim ntawm cov cuab yeej siv los tsev ib qho khoom siv pov tseg, uas nyob rau ntawm ib qho kawg cev -zoo li structureterminates hauv av iav sib koom ua ke rau siv hauv kev sib txuas thev naus laus zis cev mus rau ib lub nkoj tshuaj tiv thaiv, rau lub hom phiaj ntawm kev ua kom lub nkoj tsis muaj dej noo.
Yuav ua li cas thaum calcium chloride ntxiv rau hauv dej?
Khoom calcium chloride yog deliquescent, lub ntsiab lus nws tuaj yeem nqus dej txaus los hloov mus rau cov kua brine. 3. Thaum muab tso rau hauv dej , khov calcium chloride tso tawm nyob rau hauv cov tshuaj tiv thaiv exothermic. Qhov no brine txo qis lub freezingpoint ntawm dej kom yaj ntxiv daus thiab dej khov ntawm kev sib cuag.
Pom zoo:
Dab tsi yog enthalpy ntawm calcium chloride?
Tus nqi ntsuas rau enthalpy ntawm kev daws rau anhydrous calcium chloride (tus nqi uas peb tab tom sim xam ntawm no) yog li -80 kJ mol-1
Thaum koj kub calcium carbonate ib qho khoom dawb nrog cov mis CaCO3 nws tawg los ua cov khoom calcium oxide CaO thiab carbon dioxide gas co2?
Thaum tshav kub kub tshaj 840 ° C, calcium carbonate decomposes, tso cov pa roj carbon dioxide thiab tawm hauv qab calcium oxide - cov khoom dawb. Calcium oxide hu ua txiv qaub thiab yog ib qho ntawm 10 cov tshuaj uas tsim tawm txhua xyoo los ntawm thermal decomposition ntawm limestone
Cov tshuaj tiv thaiv dab tsi yog calcium carbonate calcium oxide carbon dioxide?
Calcium carbonate tau kub siab kom txog thaum nws dhau los ua thermal decomposition los tsim calcium oxide thiab carbon dioxide. Cov calcium oxide (unslaked txiv qaub) yog yaj hauv dej los tsim calcium hydroxide (limewater). Bubbling carbon dioxide los ntawm qhov no ua ib qho kev ncua ntawm calcium carbonate
Puas yog calcium chloride yog cov khoom siv hluav taws xob zoo?
Feem ntau nyob rau hauv lub xeev molten, nws yog ib tug zoo conductor ntawm hluav taws xob. Calcium chloride yog ib tug phem conductor ntawm tshav kub. Nws qhov kub hnyiab yog siab li 1935 ° C. Nws ishygroscopic nyob rau hauv cov xwm thiab absorbs noo noo los ntawm huab cua
Vim li cas lawv muab calcium chloride tso rau hauv dej haus?
Nws feem ntau yog siv los ua ib qho electrolyte hauv cov dej haus kis las thiab lwm yam dej haus, suav nrog cov dej hauv lub raj mis. Cov saj qab ntsev heev ntawm calcium chloride yog siv los ua cov kua txiv hmab txiv ntoo uas tsis ua rau cov zaub mov muaj sodium ntau ntxiv
