Iyini i-Anhydrous Calcium Chloride?

I-Anhydrous Calcium Chlorideiyinhlanganisela yamakhemikhali enefomula ethi CaCl₂, futhi iwuhlobo lukasawoti we-calcium. Igama elithi “anhydrous” libonisa ukuthi alinawo ama-molecule amanzi. Le nhlanganisela i-hygroscopic, okusho ukuthi inobudlelwane obuqinile bamanzi futhi imunca kalula umswakama endaweni ezungezile.

Isakhiwo samakhemikhali se-anhydrous calcium chloride siqukethe i-athomu eyodwa ye-calcium (Ca) kanye nama-athomu amabili e-chlorine (Cl). Imhlophe, i-crystalline eqinile ekamelweni lokushisa, kodwa ukubonakala kwayo kungahluka kuye ngezinga lokuhlanzeka. Enye yezinto eziphawulekayo ze-anhydrous calcium chloride yikhono layo lokwakha ama-hydrated compounds nama-molecule amanzi, okwenza kube usizo emisebenzini ehlukahlukene.

I-Anhydrous calcium chloride ikhiqizwa ngokwentengiso ngokusabela kwe-calcium carbonate (CaCO₃) nge-hydrochloric acid (HCl). I-chemical equation yale nqubo ithi:

I-CaCO₃ + 2HCl → CaCl₂ + CO₂ + H₂O

Umkhiqizo owumphumela, i-anhydrous calcium chloride, ube usucutshungulwa ngokucophelela ukuze kukhishwe noma yikuphi okuqukethwe kwamanzi asele. Ukungabikho kwama-molecule amanzi kuyenza ibe inhlanganisela eguquguqukayo enokusetshenziswa okuningana okubalulekile kuzo zonke izimboni ezahlukene.

Enye yezicelo eziyinhloko ze-anhydrous calcium chloride injenge-desiccant noma i-ejenti yokomisa. Ngenxa yemvelo yayo ye-hygroscopic, imunca ngempumelelo umhwamuko wamanzi ovela emoyeni, iwenze ube wusizo ekuvimbeleni umonakalo ohlobene nomswakama emikhiqizweni ehlukahlukene, okuhlanganisa izimpahla ezipakishiwe, izinto zikagesi, namakhemikhali.

Ngaphezu kwendima yayo njenge-desiccant, i-anhydrous calcium chloride isetshenziswa kakhulu ekusetshenzisweni kwe-de-icing. Uma isakazwa ezindaweni ezineqhwa noma ezineqhwa, yehlisa indawo yamanzi aqandayo, okuholela ekuncibilikeni kweqhwa neqhwa. Lokhu kwenza kube isithako esivamile ekwakhiweni kukasawoti womgwaqo okusetshenziselwa ukuthuthukisa ukuphepha emgwaqeni ebusika ngokuvimbela ukwakheka kweqhwa emigwaqweni.

I-Anhydrous calcium chloride iphinde ithole ukusetshenziswa embonini yokudla njenge-ejenti yokuqinisa izithelo nemifino. Isiza ukugcina ukuthungwa kwalezi zinto ezibolayo phakathi nokucubungula nokugcinwa. Ngaphezu kwalokho, isetshenziswa embonini kawoyela negesi ukumba kahle nokuqedela uketshezi, isebenza njenge-ejenti eqeda amanzi emzimbeni ukuvimbela ukuvuvukala kokwakheka kobumba.

Naphezu kokusetshenziswa kwayo okuhlukahlukene, i-anhydrous calcium chloride kufanele iphathwe ngokucophelela, ngoba ingabangela ukucasuka esikhumbeni namehlo. Izinyathelo zokuphepha ezifanele, okuhlanganisa ukusetshenziswa kwezinto zokuzivikela ezifana namagilavu ​​nezibuko, zibalulekile lapho usebenza nale nhlanganisela.

Sengiphetha, i-anhydrous calcium chloride iyinhlanganisela yamakhemikhali ebalulekile enohlu olubanzi lwezinhlelo zokusebenza ngenxa yemvelo yayo ye-hygroscopic. Kusukela ekuvimbeleni ukulimala komswakamo ukuya ekusebenzeni njenge-ejenti yokususa uqweqwe lweqhwa, le nhlanganisela idlala indima ebalulekile ezimbonini ezahlukahlukene, ikhombisa ukuguquguquka kwayo kanye nokubaluleka kwayo ezinhlelweni zesimanjemanje.
