Calcium kloridendi mankhwala wopangidwa ndi chloride ndi calcium zinthu.Mankhwalawa ndi CACL2, omwe ndi owawa pang'ono.Ndi mtundu wa ion halide, wokhala ndi zoyera, zolimba kapena particles kutentha.Zomwe zimagwiritsidwa ntchito nthawi zambiri zimaphatikizapo saline, osungunula mumsewu ndi ma desiccants omwe amagwiritsidwa ntchito mufiriji.
Calcium kloridekuchokera maonekedwe makamaka anawagawa madzi calcium kolorayidi ndi olimba kashiamu kolorayidi.Zamadzimadzi calcium kolorayidi ndi amadzimadzi njira ya calcium kolorayidi, ambiri zili kashiamu kolorayidi ndi 27-42%.Ngati zili kashiamu kolorayidi kwambiri, yankho adzakhala viscous kwambiri, kutentha amachepetsa njira solidification, pali mayendedwe, kutsitsa, ntchito mavuto ndi mavuto ena.Olimba kashiamu kolorayidi akhoza kugawidwa mu flake, mpira, ufa ndi zina zitatu, zikuchokera ake ogaŵikana kashiamu kolorayidi dihydrate kapena anhydrous calcium kolorayidi.Kashiamu kolorayidi mu kashiamu kolorayidi dihydrate nthawi zambiri ndi 72–78%, ndi calcium kolorayidi mu anhydrous kashiamu kloride kuposa 90% kapena 94% (makamaka spherical calcium).
Kunena zambiri, kupanga ozungulira kashiamu ndi zovuta, ndondomeko bata si mkulu, magawo opaleshoni ndi okhwima, kupanga mowa mowa ndi mkulu pang'ono, koma mankhwala ndi ubwino wa maonekedwe okongola, fluidity wabwino wa Chemicalbook, ayi. fumbi, lopanda caking, losavuta kuyamwa chinyezi, kotero mtengo wogulitsa wa spherical calcium calcium chloride ndi wapamwamba kuposa flake kapena ufa wa calcium chloride, womwe umagwiritsidwa ntchito kwambiri panyumba ya desiccant, kutumiza kunja Kwa chipale chofewa ndi madzi osungunuka.Ndi kalasi, kashiamu kolorayidi akhoza kugawidwa mu mafakitale kalasi kashiamu kolorayidi ndi chakudya kalasi kashiamu kolorayidi.Poyerekeza ndi kalasi ya calcium chloride ya mafakitale, kalasi ya calcium chloride ya chakudya imakhala ndi zofunika kwambiri pakuwongolera kupanga komanso kuyera kwazinthu zapamwamba.Miyezo ya dziko yawonjezera zizindikiro monga mtundu, heavy metal (lead, arsenic) ndi fluorine zomwe zili muzinthu.Zakudya za calcium chloride zimatha kugwiritsidwa ntchito ngati stabilizer, solidifying agent, thickening agent, nutritive fortifying agent, desiccant, etc., ntchito zake zosiyanasiyana zimaphatikizapo nyemba zobiriwira, zonona zonona, zakumwa zoziziritsa kukhosi, msuzi wotsekemera, kupanikizana, kusakaniza madzi ndi mafakitale ogulitsa zakudya. thandizo.
Ntchito zazikulu:
Calcium klorideamapangidwa ndi klorini ndi kashiamu ndipo ali ndi mankhwala CaCl2.Ndi mtundu wa ionic halide, yoyera yolimba kutentha komanso osalowerera mu njira yamadzi.Calcium chloride, ma hydrates ndi mayankho ake ali ndi ntchito zofunika pakupanga zakudya, zomangira, zamankhwala ndi biology.
Kugwiritsa ntchito mafakitale
1, yogwiritsidwa ntchito ngati desiccant yambiri, monga nayitrogeni, oksijeni, haidrojeni, hydrogen chloride, sulfure dioxide ndi kuyanika kwa mpweya wina.Amagwiritsidwa ntchito ngati dehydrating popanga ma alcohols, esters, ethers ndi acrylics.Calcium chloride aqueous solution ndi firiji yofunika kwambiri popangira firiji makina ndi kupanga ayezi.Ikhoza kufulumizitsa kuumitsa konkire ndikuwonjezera kukana kozizira kwa matope omanga.Ndi antifreeze wothandizira wabwino kwambiri womanga.Amagwiritsidwa ntchito ngati doko antifogging wothandizira komanso wotolera fumbi mumsewu, nsalu yotchinga moto.Amagwiritsidwa ntchito ngati woteteza komanso woyenga wa aluminiyamu magnesium metallurgy.Ndiwo mpweya wopangira ma pigment a nyanja.Amagwiritsidwa ntchito pochotsa zinyalala za pepala.Ndiwo zida zopangira mchere wa calcium.
2. Chelating wothandizira;machiritso wothandizira;Mphamvu ya calcium;Refrigerating refrigerant;Desiccant;Anticoagulant;Microbiotics;Pickling wothandizira;Zowonjezera minofu.
3, yogwiritsidwa ntchito ngati desiccant, wosonkhanitsira fumbi la pamsewu, wopangira chifunga, chotchinga moto chansalu, zosungira zakudya komanso zomwe zimagwiritsidwa ntchito popanga mchere wa calcium.
4, amagwiritsidwa ntchito ngati chowonjezera chamafuta.
5, yogwiritsidwa ntchito ngati ma analytical reagent.
6. Amagwiritsidwa ntchito makamaka pochiza tetany, urticaria, exusive edema, matumbo ndi ureter colic, poizoni wa magnesium ndi zina zotero chifukwa cha kuchepa kwa magazi a calcium.
7, yomwe imagwiritsidwa ntchito m'makampani azakudya ngati othandizira calcium, machiritso, chelating agent ndi desiccant.
8, imatha kuonjezera permeability wa bakiteriya cell khoma.
Kugwiritsa ntchito chakudya
1. Calcium klorideakhoza kuwonjezeredwa ku zakudya monga chowonjezera cha calcium, kapena ngati coagulant ya tofu ndi tchizi.
2. Calcium chloride ikhoza kuwonjezeredwa ku zakumwa zoledzeretsa ndi zakumwa zoziziritsa kukhosi kuti ziwongolere PH ndi kuuma kwa zakumwazo.
3. Amagwiritsidwa ntchito m'makampani azakudya monga calcium yolimbitsa thupi, machiritso, chelating agent ndi desiccant.
4. Iwo akhoza kuonjezera permeability wa bakiteriya selo khoma.
5. The Kutha ndi exothermic katundu wa kashiamu kolorayidi kumabweretsa ntchito yake kudziletsa Kutentha zitini ndi Kutentha ziyangoyango.
Njira yokonzekera:
1. Calcium chloride dihydrate (njira yochepetsera madzi m'thupi):
The edible calcium kolorayidi mankhwala anakonzedwa ndi kuyanika ndi dehydrating calcium kolorayidi dihydrate pa 200 ~ 300 ℃.
Chemical reaction equation ndi motere:
Pakuti ndale calcium kolorayidi njira, kutsitsi kuyanika nsanja angagwiritsidwe ntchito pa 300 ℃ otentha mpweya otaya kutsitsi kuyanika madzi m`thupi, kukonzekera anhydrous calcium kolorayidi ufa anamaliza mankhwala.
2.Njira yowumitsa ndi yothira madzi:
Njira yosalowerera ndale ya calcium chloride, yomwe yachotsa arsenic ndi zitsulo zolemera, imapopera mu mawonekedwe a nkhungu pamwamba pa nsanja yowumitsa yopopera kudzera pamphuno, ndikukhudzana ndi 300 ℃ mpweya wotentha wa gasi kuti uume ndi kutaya madzi, ndiyeno ufa wa anhydrous calcium chloride ndi adapangidwa kuti akonze zinthu zodyedwa za anhydrous calcium chloride.
3. Njira ya mowa wa amayi:
Njira yamadzimadzi imapezeka powonjezera mkaka wa laimu kwa mowa wa mayi mu njira ya koloko phulusa ndi ammonia alkali njira, yomwe imapangidwa ndi evaporation, ndende, kuzirala ndi kulimba.
4. Njira yowola mophatikiza:
Amapangidwa ndi zochita za calcium carbonate (mwala wa laimu) wokhala ndi hydrochloric acid.
Chemical reaction equation: CaCO3+2HCl=CaCl2+H2O+CO2↑.
Masitepe omwe ali pamwambawa akamaliza, kutentha kumatenthedwa kufika madigiri 260 Celsius, kuphulika ndi kutaya madzi m'thupi.
5. Njira yoyeretsera:
Zomwe zimapangidwira popanga sodium hypochlorite zimayengedwa.
Chotsatira cha njira ya Solvay yokonzekera sodium carbonate.
Ca(OH)2 + 2NH4Cl → CaCl2 + 2NH3 + 2H2O
Njira zodzitetezera:
Kutsekedwa ntchito kumapangitsanso mpweya wabwino.Ogwira ntchito ayenera kuphunzitsidwa mwapadera ndikutsata ndondomeko zoyendetsera ntchito.Ndikofunikira kuti ogwira ntchito azivala zodzikongoletsera zodzitetezera kuti apewe fumbi.Pogwira, kukweza ndi kutsitsa pang'ono kuyenera kuchitidwa pofuna kupewa kuwonongeka kwa zotengera ndi zotengera.
Kusamala posungira:
Sungani m'nyumba yosungiramo zinthu zoziziritsa kukhosi komanso mpweya wokwanira.Zotengerazo ziyenera kutsekedwa ndi kutetezedwa ku chinyezi.Sungani padera ndi zinthu zokoma.
