Calcium Chloride Chaw tsim tshuaj paus
Taw qhia
Calcium chloride yog ib qho sib xyaw nrog cov tshuaj formula CaCl2.
Chemical Properties:
Calcium chloride yog ntsev uas muaj calcium thiab chlorine ions. Nws yog heev soluble nyob rau hauv dej thiab muaj ib tug dawb tsos.
Teb:CaCO3 + 2HCl = CaCl2 Calcium Chloride + H2O + CO2
Calcium chloride yog hygroscopic heev, muaj kuab heev, thiab tuaj yeem yaj hauv dej yooj yim.
Thaum yaj nyob rau hauv dej, nws tsim ib tug loj npaum li cas ntawm cov tshuaj tshav kub thiab zoo heev txo lub freezing point ntawm dej, muaj zog anti-freezing thiab de-icing los.
Cov ntawv thov kev lag luam
Deicing thiab Anti-Icing:
Ib qho kev siv ntau tshaj plaws ntawm calcium chloride yog nyob rau hauv deicing thiab anti-icing daws. Nws qhov xwm txheej hygroscopic tso cai rau nws nyiam cov dej noo los ntawm huab cua, txo qhov dej khov ntawm dej thiab tiv thaiv kev tsim cov dej khov ntawm txoj kev, kev taug kev, thiab kev khiav. Calcium chloride yog nyiam rau deicing vim nws cov hauj lwm zoo txawm nyob rau hauv qis kub piv rau lwm yam deicing agents.
Dust Control:
Calcium chloride yog siv dav rau kev tiv thaiv plua plav ntawm txoj kev, chaw tsim kho, thiab kev ua haujlwm tsuas. Thaum ua ntawv thov rau qhov chaw uas tsis tau ntim, nws absorbs noo noo los ntawm huab cua thiab hauv av, tiv thaiv kev tsim cov hmoov av. Qhov no tsis tsuas yog txhim kho kev pom thiab huab cua zoo xwb tab sis kuj txo cov nqi kho mob cuam tshuam nrog kev tswj cov plua plav.
Pob zeb Acceleration:
Nyob rau hauv kev tsim kho kev lag luam, calcium chloride yog ua hauj lwm raws li lub pob zeb accelerator, ua kom lub teeb thiab hardening txheej txheem ntawm pob zeb. Los ntawm kev nce tus nqi ntawm hydration, nws tso cai rau lub sijhawm tsim kho sai dua thiab ua rau kev ua haujlwm txuas ntxiv txawm tias nyob rau hauv qhov txias dua, qhov chaw ua vaj tse ib txwm yuav ncua sijhawm.
Kev ua zaub mov:
Hauv kev ua zaub mov, calcium chloride pom siv los ua tus neeg sawv cev ruaj khov, khaws cia, thiab ntxiv. Nws txhim khu kev ntxhib los mos thiab ruaj khov ntawm ntau yam khoom noj xws li cov txiv hmab txiv ntoo thiab zaub, taum paj, thiab pickles. Tsis tas li ntawd, calcium chloride yog ua hauj lwm nyob rau hauv cheese-ua los txhawb coagulation thiab txhim kho yield.
Desiccation:
Calcium chloride ua ib qho desiccant hauv ntau cov txheej txheem kev lag luam uas tswj cov dej noo tseem ceeb. Nws yog siv rau hauv daim ntawv thov kom qhuav cov pa kom tshem tawm cov dej vapor los ntawm cov pa roj thiab tswj cov khoom siv xws li cov tub yees, cov cua txias, thiab cov tshuab cua compressed.
Roj thiab Gas Extraction:
Hauv kev lag luam roj thiab roj, calcium chloride ua lub luag haujlwm tseem ceeb hauv kev ua kom zoo drilling thiab ua tiav cov haujlwm. Nws yog siv los ua cov kua dej ntxiv los tswj cov viscosity, inhibit av nplaum o, thiab tswj kev ruaj ntseg zoo. Calcium chloride brines kuj tau ua haujlwm hauv hydraulic fracturing (fracking) los txhim kho cov dej rov qab thiab tiv thaiv kev tsim kev puas tsuaj.
Thaum tshav kub kub cia:
Ntxiv rau nws qhov xwm txheej hygroscopic, calcium chloride nthuav tawm cov khoom exothermic thaum yaj hauv dej, yog li hydrated ntsev CaCl2 yog cov khoom cog lus rau qib qis thermochemical kub cia.
