isicelo se-aluminium hydroxide

I-aluminium hydroxide, ukwakheka kwayo okuyi-Al(OH)3, ingatholakala emvelweni ngalezi zindlela ezilandelayo: i-gibbsite, okuyiminerali, kanye ne-doyleite, i-nordstrandite kanye ne-bayerite, konke okuyi-polymorphs ezingavamile. Ngokusekelwe ezicini zayo, singasho ukuthi i-aluminium hydroxide ibonakala iyi-antacid. Inezindlela ezahlukahlukene zokusetshenziswa, okuyinhloko phakathi kwazo ukusetshenziswa kwezokwelapha.

Izakhiwo Zamakhemikhali

Kunezinhlobo eziningi ezahlukene ze-aluminium oxide, okuhlanganisa zombili izinhlobo ze-crystalline kanye ne-non-crystalline. Iyisivikelo sikagesi, okusho ukuthi ayiqhubi ugesi, futhi futhi inokushisa okuphezulu. Ngaphezu kwalokho, ngesimo sayo se-crystalline,i-corundum, ubulukhuni bayo buyenza ifaneleke njengesithambisi. Izinga eliphezulu lokuncibilika kwe-aluminium oxide lenza kube yinto enhle yokungaguquki yokuhlobisa izinto ezisetshenziswayo ezishisa kakhulu njengezitofu, izitofu, izitofu zokushisa, iziphehli zezinhlobo ezahlukene, kanye nezitofu zokushisa.

Izakhiwo ze-aluminium hydroxide

I-aluminium hydroxide ehlanziwe inohlobo lwempuphu enkulu enombala omhlophe noma ama-granule anobukhulu obucishe bube ngu-2.42 g nge-mL. I-aluminium hydroxide ngeke incibilike ku-amanzi, kodwa izoncibilika kuphela ezisekelweni nakuma-asidi. Ungalindela ukuthi i-aluminium hydroxide isebenze njenge-amphoteric substance emanzini. Uma kukhona isisekelo esiqinile, i-aluminium hydroxide izosebenza njenge-asidi. Futhi uma kukhona i-asidi enamandla, izosebenza njengesisekelo esiqinile.
I-aluminium hydroxide kufanele iphathwe ngokucophelela ngoba ukuvezwa kwayo kungabangela ukucasuka. Kodwa-ke, kuzoba khona ukulimala okuncane nokusele kuphela. Ngokuphathelene nokusha, i-aluminium hydroxide ayishisi futhi ngeke ishe. Ngaphandle kwalokho, i-aluminium hydroxide ayisebenzi, ngakho-ke, izinzile kokubili ezimweni zomlilo kanye nasemanzini.

Ukusetshenziswa kwe-aluminium hydroxide

I-aluminium hydroxide inezindlela eziningi zokusebenzisa; abanye abantu bakholelwa ukuthi lokhu kusetshenziswa akupheli. Ukuze sibonise ububanzi bokusetshenziswa, singasho ukuthi i-aluminium hydroxide isetshenziswa njenge-mordant kumadayi, i-purifier ye-amanzi, isithako sezimonyo, ngisho nanjengesakhi sezinqubo zokuthwebula izithombe. Kukhona futhi ukusetshenziswa okuncane ezintweni zobumba nasekwakhiweni. Kodwa insimu ebaluleke kakhulu lapho kusetshenziswa khona i-aluminium hydroxide umuthi.
