Yini i-anhydrous calcium chloride?

I-Anhydrous calcium chlorideiyingxenye yamakhemikhali ngefomula ye-CACL₂, futhi kuwuhlobo kasawoti we-calcium. Igama elithi "Anhydrous" libonisa ukuthi alinawo ama-molecule wamanzi. Le nhlanganisela i-hygroscopic, okusho ukuthi inobudlelwano obuqinile emanzini futhi imunca kalula umswakama ovela endaweni ezungezile.

Isakhiwo samakhemikhali se-anhydrous calcium chloride siqukethe i-athomu elilodwa le-calcium (CA) nama-athomu amabili we-chlorine (cl). Kuyimhlophe, i-crystalline eqinile emazingeni okushisa asekamelweni, kepha ukubukeka kwayo kungahluka ngokuya ngezinga lobumsulwa. Enye yezakhiwo eziphawuleka ze-anhydrous calcium chloride yikhono lazo lokusebenza ngama-hydrate anama-molecule wamanzi, okwenza kube wusizo ezinhlelweni ezahlukahlukene.

I-Anhydrous calcium Chloride yenzelwe ukuhweba ngokuthengiswa ngokusabela kwe-calcium carbonate (Caco₃) nge-hydrochloric acid (HCL). I-equation yamakhemikhali yale nqubo yile:

Caco₃ + 2hcl → CACL₂ + Co₂ + H₂O

Umkhiqizo ongenzeka, i-anhydrous calcium chloride, bese ucutshungulwa ngokucophelela ukuze ususe noma yikuphi okuqukethwe kwamanzi okusele. Ukungabikho kwama-molecule wamanzi kwenza kube yindawo eguquguqukayo esebenzisa izinto eziningana ezibalulekile kuyo yonke imboni ehlukene.

Enye yezicelo eziyisisekelo ze-anhydrous calcium chloride injenge-desiccant noma i-ejenti yomiswa. Ngenxa yemvelo yayo ye-hygroscopic, imunca ngempumelelo umphunga wamanzi ovela emoyeni, okwenza kube yigugu ekuvikeleni ukulimala okuhlobene nomswakama emikhiqizweni ehlukahlukene, kufaka phakathi izimpahla ezihlanganisiwe, ama-elekthronikhi namakhemikhali.

Ngaphezu kwendima yayo njenge-desiccant, i-anhydrous calcium chloride isetshenziswa kabanzi kuzinhlelo zokusebenza ze-de-icing. Lapho usakazeka ezindaweni ezinamakhaza noma ezineqhwa, wehlisa iphuzu lamanzi, okuholela ekuncibilikeni kweqhwa neqhwa. Lokhu kwenza kube yizithako ezijwayelekile ekwakhekeni kosawoti komgwaqo okusetshenziselwa ukuthuthukisa ukuphepha komgwaqo ebusika ngokuvimbela ukwakheka kweqhwa emigwaqweni.

I-Anhydrous calcium Chloride futhi ithola uhlelo lokusebenza embonini yokudla njengomenzeli wokuqina wezithelo nemifino. Kuyasiza ukugcina ukuthungwa kwalezi zinto ezingokonakalayo ngesikhathi sokucubungula nokugcina. Ngaphezu kwalokho, kusetshenziswa emkhakheni kawoyela negesi ukuze kuqedwe kahle futhi kuqedwe ukuqeda uketshezi, kusebenza njenge-ejenti yokuphelelwa ngamandla ukuvimbela ukuvuvukala kokwakhiwa kobumba.

Naphezu kwezicelo zayo ezahlukahlukene, i-anhydrous calcium chloride kufanele iphathwe ngokunakekelwa, ngoba ingadala ukucasuka esikhunjeni namehlo. Ukuphepha okufanelekile kokuphepha, okubandakanya ukusetshenziswa kwamagiya okuvikela anjengamagilavu ​​nama-goggles, kubalulekile lapho usebenza nale nhlanganisela.

Ekuphetheni, i-anhydrous calcium chloride iyindawo ebalulekile yamakhemikhali enobubanzi bezicelo ngenxa yemvelo yayo ye-hygroscopic. Ukusuka ekuvinjeleni ukulimala komswakama ukuze ukhonze njenge-ejenti ye-de-icing, leli ndaba libamba iqhaza elibalulekile ezimbonini ezahlukahlukene, libonisa ukuguquguquka kwalo nokubaluleka kwezicelo zanamuhla.
