Izakhiwo ezibonakalayo kanye nokusebenzisa i-calcium chloride

I-calcium chloride ngusawoti owenziwe ngama-chloride ion nama-calcium ion. I-Anhydrous calcium Chloride inokutholwa okuqinile komswakama, okusetshenziswa njenge-desiccant yezinto ezahlukahlukene, ngaphezu kothuli lomgwaqo, ukunqwabelana, okuqandisayo, i-ejenti yokuhlanza amanzi, i-ejenti yokuhlanza amanzi, umenzeli wokuhlanza amanzi, umenzeli wokuhlanza amanzi, umenzeli wokuhlanza amanzi, umenzeli wokuhlanza amanzi, unamathisele i-ejenti. Kuyinto esetshenziswayo esetshenziswayo yamakhemikhali i-reagent, izinto ezivuthiwe emikhakheni, izengezo zokudla, izithasiselo zokudla kanye nezinto zokwenziwa zokwenziwa kwe-calcium yensimbi.

Izakhiwo ezibonakalayo ze-calcium chloride

I-calcium chloride iyi-colorless cubic crystal crystal, emhlophe noma i-off-white, granular, honey comlock block, sperfur, i-granular, i-powded. Iphuzu elincibilikayo 782 ° C, density 1.086 g / ml ku-20 ° C, abilayo iphuzu 1600 ° C, amanzi we-solubity 740 g / l. I-FTICH EQINISEKILE, NGEMPELA, ukunambitheka okubabayo kancane. I-hygroscopic ngokweqile futhi ihlehliswe kalula lapho ivezwa umoya.
Ukuncibilika kalula emanzini, ngenkathi kukhishwa inani elikhulu lokushisa (i-calcium chloride disolution enkundleni ye -176.2cal / g), ikhambi lalo lamanzi linama-acid kancane. Incibilika utshwala, i-acetone, actic ac acid. Ukuphendula nge-ammonia noma i-ethanol, i-CACL2 · 8NHH3 ne-CACL2 · 4c2h5oh izakhiwo, ngokulandelana. Emazingeni okushisa aphansi, ikhambi likhanyisela futhi liqonde njenge-hexahydrate, elihlukaniswa kancane kancane emanzini alola amakhilogremu lapho lifuthelwa amanzi lapho lifudumeza i-calcium chloride emhlophe ye-anhydrous anhydrous.

I-Anhydrous calcium chloride

1, I-PRICTIC NEMIPHAKATHI: I-Crystal engenamibala ye-Cubic Crystal, i-White noma i-Off-porous block noma i-granular solid. Isimo esilinganiselwe ngu-2.15, indawo yokuncibilikisa ingu-782 ℃, iphuzu elibilayo lingaphezulu kwe-1600 ℃, ukuguquguquka okubabayo, kulula ukuncibilikisa, u-acrylic unambitheka, uviniga wamanzi, uviniga wamanzi, i-acetic vini acid.

2, Ukusetshenziswa Komkhiqizo: Kuyi-ejenti evuthayo yokukhiqizwa kwemibala yeLake Lake. Ukukhiqizwa kwe-nitrogen, igesi ye-acetylene, i-hydrogen chloride, umoya-mpilo kanye nezinye i-desiccant yegesi. I -OLLS, izibusiso, ama-ester kanye nama-acrylic resins asetshenziswa njengama-dehydrating dehydrating, futhi izisombululo zazo ezinamanzi zibalulekile eziqandisini eziqandisini nesiqandisini. Kungasheshisa ukuqina kokhonkolo, kwandise ukumelana nokubanda kodaka kasimende, futhi kungumenzeli omuhle kakhulu we-antifree. Kusetshenziswa njenge-ejenti evikelayo ye-aluminium magnesium metallurgy, i-ejenti yokucwengeka.

I-Flake calcium chloride

1, I-Physical and Chemical Properties: I-Crystal engenamibala, lo mkhiqizo umhlophe, u-off-white crystal. Ukunambitheka okubabayo, ukudilizwa okunamandla.
Ubuningi bayo obuhlobene ngu-0.835, ukuncibilika kalula emanzini, ikhambi layo lamanzi alithathi hlangothi noma kancane, liwonakalisiwe, lincibilika e-Ether, futhi likhishwe emanzini lapho lifudumala ku-260 ℃. Ezinye izakhiwo zamakhemikhali zifana ne-anhydrous calcium chloride.

2, umsebenzi kanye nokusebenzisa: Flake calcium chloride esetshenziswe njengeqandisini; Umenzeli we-Antifreeel; Iqhwa elibunjiweyo noma iqhwa; Amalangabi amalangabi wokuqeda nokuqeda izindwangu zekotoni; Izinkuni zokugcina; Ukukhiqizwa kwenjoloba njengomenzeli wokugoqa; Isitashi esixubile sisetshenziswa njenge-ejenti ye-gluing.

Isixazululo samanzi se-calcium chloride aqued

Isixazululo se-calcium chloride sinezimpawu zokuqhutshwa, indawo ephansi yokuqalisa kunamanzi, ukuncipha kokushisa ngokuxhumana namanzi, futhi kunomsebenzi ongcono we-adsorption, futhi iphuzu laso eliphansi liyasetshenziswa ezindaweni ezahlukahlukene zokukhiqiza nezindawo zomphakathi.

Indima ye-calcium chloride solution:

1. I-Alkalialine: I-calcium ion hydrolysis yi-alkali, futhi i-hydrogen chloride iyi-shiotile ngemuva kwe-chloride ion hydrolysis.
2, Ukuhunyushwa: Kunama-ion kwikhambi elingahamba ngokukhululeka.
I-3, indawo eqandayo: I-calcium Chloride Solution FreeZing Point iphansi kunamanzi.
I-4, iphuzu elibilayo: I-calcium chloride aquride aquride ikhambi elibilayo liphezulu kunamanzi.
I-5, ukuhwamuka kokuhwamuka

Desictant

I-calcium chloride ingasetshenziswa njenge-desiccant noma i-ejenti yokuphamba amagesi kanye noketshezi lwe-organic. Kodwa-ke, ngeke isetshenziselwe isome i-ethanol ne-ammonia, ngoba i-ethanol ne-ammonia asabela nge-calcium chloride ukwakha i-cacl2 · 4c2hroh ne-ammonia eziyinkimbinkimbi ye-cacl2 · 8hhh3, ngokulandelana. I-anhydrous calcium chloride ingenziwa futhi ibe yimikhiqizo yasendlini esetshenziswa njenge-ejenti ye-air hygroscopic, i-anhydrous calcium chloride njengoba i-ejenti yokuthola amanzi ivunywa yi-FDA yokugqoka usizo lokuqala, ukuqhamuka nendima yayo ukuqinisekisa ukoma kwesilonda.
Ngoba i-calcium chloride ayithathi hlangothi, ingama igesi e-acidic noma i-alkali kanye noketshezi lwe-organic, kodwa futhi ngelebhu, kodwa futhi e-throgen, i-sulffur dioxide, i-nitrogen dioxide, njll., Lapho yomisa lokhu kukhiqizwa amagesi. I-Granurar Anhydrous Calloride imvamisa isetshenziswa njenge-desiccant yokugcwalisa amapayipi omiswa, futhi umlotha wasolwandle (noma umlotha wasolwandle omisiwe nge-calcium chloride ingasetshenziselwa ukukhiqizwa komlotha we-soda. Amanye ama-dehidifier asendlini asebenzisa i-calcium chloride ukumunca umswakama ovela emoyeni.
I-anhydrous calcium chloride isatshalaliswa emphakathini we-sandy, futhi impahla ye-hygroscopic ye-anhydrous calcium chloride isetshenziselwa ukususa umswakama emoyeni lapho umswakama womoya uphansi kunendawo yezomgwaqo ukuze ugcine uthuli emgwaqweni.
