Txoj kev npaj:
1.Calcium chloride dihydrate (dehydration method) txoj kev:
Cov khoom noj uas tsis muaj calcium chloride tau npaj los ntawm kev ziab thiab dehydrating calcium chloride dihydrate ntawm 200 ~ 300 ℃.
Cov tshuaj tiv thaiv kab mob sib npaug yog raws li hauv qab no:
Rau nruab nrab calcium chloride tov, tshuaj tsuag kom qhuav ntauwd yuav siv tau ntawm 300 ℃ kub gas flow rau tshuaj tsuag kom qhuav lub cev qhuav dej, npaj anhydrous calcium chloride hmoov cov khoom tiav.
2. Txau kom qhuav thiab dewatering txoj kev:
Cov tshuaj ua kom zoo tsis zoo calcium chloride, uas tau tshem tawm arsenic thiab hnyav hlau, yog txau rau hauv daim ntawv pos huab saum toj no lub tshuab ziab khaub ncaws los ntawm lub nozzle, thiab tiv tauj nrog 300 ℃ kub roj ntws kom qhuav thiab lub cev qhuav dej, thiab tom qab ntawd hmoov tsis muaj calcium chloride. tau los npaj edible anhydrous calcium chloride khoom.
3. Niam cawv txoj kev:
Cov tshuaj aqueous yog tau los ntawm kev ntxiv cov kua txiv qaub rau hauv cov kua txiv hmab txiv ntoo hauv cov txheej txheem ntawm soda tshauv los ntawm ammonia alkali txoj kev, uas yog tsim los ntawm evaporation, concentration, txias thiab solidification.
4. Compound decomposition method:
Nws yog tsim los ntawm kev ua ntawm calcium carbonate (limestone) nrog hydrochloric acid.
Cov tshuaj tiv thaiv kab mob: CaCO3 + 2HCl = CaCl2 + H2O + CO2↑.
Tom qab ua tiav cov kauj ruam saum toj no, cov cua sov yog rhuab mus rau 260 degrees Celsius, evaporation thiab lub cev qhuav dej.
5.Refining method:
Cov by-product nyob rau hauv zus tau tej cov sodium hypochlorite yog refined.
Ib tug los ntawm cov khoom ntawm cov txheej txheem Solvay rau kev npaj ntawm sodium carbonate.
Ca(OH)2 + 2NH4Cl → CaCl2 + 2NH3 + 2H2O
Kev ceev faj ua haujlwm:
Kaw ua haujlwm los txhim kho qhov cua.Cov neeg ua haujlwm yuav tsum tau kawm tshwj xeeb thiab ua raws li cov txheej txheem ua haujlwm.Nws raug nquahu kom cov neeg ua haujlwm hnav tus kheej-priming lim plua plav qhov ncauj qhov ntswg kom tsis txhob muaj plua plav.Thaum tuav, lub teeb loading thiab unloading yuav tsum tau ua kom tsis txhob muaj kev puas tsuaj rau lub ntim thiab ntim.
Kev ceev faj cia:
Khaws rau hauv ib qho chaw txias, ventilated warehouse.Cov thawv ntim khoom yuav tsum tau kaw thiab tiv thaiv los ntawm noo noo.Khaws cais los ntawm cov khoom noj khoom haus.
