Wopanga Calcium Chloride
Mawu Oyamba
Calcium chloride ndi mankhwala opangidwa ndi CaCl2.
Chemical Properties:
Calcium chloride ndi mchere wopangidwa ndi ayoni a calcium ndi klorini. Amasungunuka kwambiri m'madzi ndipo ali ndi mawonekedwe oyera.
Zochita:CaCO3 + 2HCl => CaCl2 Calcium chloride + H2O + CO2
Calcium chloride ndi ya hygroscopic, yonyowa kwambiri, ndipo imatha kusungunuka m'madzi mosavuta.
Ikasungunuka m'madzi, imapanga kutentha kwakukulu kwa yankho ndikutsitsa kwambiri madzi oundana, ndi zotsatira zamphamvu zotsutsa kuzizira ndi kutsitsa.
Industrial Applications
Deicing ndi Anti-Icing:
Chimodzi mwazofala kwambiri za calcium chloride ndi mu deicing ndi anti-icing solutions. Maonekedwe ake a hygroscopic amalola kukopa chinyezi kuchokera mumlengalenga, kutsitsa malo oundana amadzi ndikuletsa kupanga ayezi m'misewu, misewu, ndi njira zowulukira ndege. Calcium chloride imakonda kupangidwa ndi deicing chifukwa cha mphamvu yake ngakhale pa kutentha kochepa poyerekeza ndi ma deicing agents.
Kuwongolera Fumbi:
Calcium chloride imagwiritsidwa ntchito kwambiri poletsa fumbi m'misewu, malo omanga, ndi ntchito zamigodi. Akagwiritsidwa ntchito pamalo osayalidwa, amayamwa chinyezi kuchokera mumlengalenga ndi pansi, ndikulepheretsa kupanga mitambo yafumbi. Izi sizimangowoneka bwino komanso mawonekedwe a mpweya komanso zimachepetsa ndalama zosamalira zomwe zimayenderana ndi kuwongolera fumbi.
Kuthamangitsa Konkriti:
M'makampani omanga, calcium chloride imagwiritsidwa ntchito ngati konkriti accelerator, kufulumizitsa kukhazikitsa ndi kuumitsa konkire. Powonjezera kuchuluka kwa hydration, zimapangitsa kuti nthawi yomanga ikhale yofulumira komanso imathandizira kuti ntchito ipitirire ngakhale kutentha kozizira kwambiri, komwe konkriti yachikhalidwe imatha kuchedwa.
Kukonza Chakudya:
Pokonza chakudya, calcium chloride imagwiritsa ntchito ngati firming agent, preservative, and additive. Imawonjezera kulimba ndi kulimba kwa zakudya zosiyanasiyana monga zipatso ndi ndiwo zamasamba zamzitini, tofu, ndi pickles. Kuphatikiza apo, calcium chloride imagwiritsidwa ntchito popanga tchizi kuti ilimbikitse kukhazikika komanso kukulitsa zokolola.
Kusiya:
Calcium chloride imagwira ntchito ngati desiccant m'njira zosiyanasiyana zamakampani pomwe kuwongolera chinyezi ndikofunikira. Amagwiritsidwa ntchito poyanika gasi kuti achotse mpweya wamadzi ku mipweya ndikusunga magwiridwe antchito a zida monga ma firiji, mayunitsi owongolera mpweya, ndi makina oponderezedwa.
Kutulutsa Mafuta ndi Gasi:
M'makampani amafuta ndi gasi, calcium chloride imagwira ntchito yofunika kwambiri pakubowola ndi kumaliza ntchito. Amagwiritsidwa ntchito ngati chowonjezera chamadzimadzi pobowola kuti athe kuwongolera kukhuthala, kuletsa kutupa kwa dongo, ndikusunga bata pachitsime. Calcium chloride brines amagwiritsidwanso ntchito mu hydraulic fracturing (fracking) kuti apititse patsogolo kuchira komanso kupewa kuwonongeka kwa mapangidwe.
Kusungirako Kutentha:
Kuphatikiza pa chikhalidwe chake cha hygroscopic, calcium chloride imawonetsa mphamvu zowonongeka ikasungunuka m'madzi, kotero mchere wa hydrated CaCl2 ndi chinthu chodalirika chosungirako kutentha kwa thermochemical.
