Aluminium hydroxide, ekwakhiweni okuyinto Al (OH) 3, kungatholakala nemvelo amafomu alandelayo: gibbsite, okuyinto amaminerali, futhi doyleite, nordstrandite futhi bayerite, konke okuyizinto polymorphs ezingavamile. Kususelwa impahla yayo, singasho ukuthi aluminium hydroxide libukeka njenge antacid. It has izindlela ezihlukene, oyinhloko phakathi okuyinto isicelo wezokwelapha.
Chemical Properties
Kukhona izinhlobo ezahlukene eziningi aluminium oxide, kuhlanganise crystalline kanye non-crystalline zombili lezi zinhlobo. Kuba yisivikelo kagesi, okusho ukuthi akusho ukuqhuba ugesi, futhi ine kuqhathaniswa okusezingeni eliphezulu conductivity ezishisayo. Ngaphezu kwalokho, ngefomu crystalline yayo, corundum, ubulukhuni bayo kwenza kube efanelekayo njengenhlangano athile. I okusezingeni eliphezulu ukuma aluminiyamu oxide kwenza kube indaba enhle refractory ngoba abami ephezulu lokushisa zikagesi like bokushisa, amaziko, incinerators, sikhungo oluhlukahlukene, futhi crucibles.
Properties of aluminium hydroxide
I ukuhlanzwa aluminium hydroxide unomzimba powder okukhulu umbala omhlophe noma elimbudumbudu nge kwabantu cishe 2,42 g ngalinye ml. Aluminium hydroxide ngeke chaza emanzini, kodwa ngeke chaza kuphela elisekela futhi acid. Ungalindela aluminium hydroxide ukwenza njenge nemiyo amphoteric emanzini. Uma isisekelo esiqinileko likhona, aluminium hydroxide uyokwenza njengoba i-acid. Futhi uma onamandla acid likhona, ke uyokwenza njengoba sizindza lesicinile.
Aluminium hydroxide kufanele aphathwe ngokuqapha ngoba ukuchayeka yayo kungabangela ukucasuka. Nokho, bathola imihuzukwana asalile kuphela abayoba khona mathupha. Kepha flammability, aluminium hydroxide akuyona oluvuthayo futhi ngeke ushise. Ngaphandle kwalokho, aluminium hydroxide akuyona esisheshayo, Ngakho-ke, esitebeleni kokubili izimo umlilo namanzi.
Izicelo aluminiyamu hydroxide
Aluminium hydroxide unemisebenzi izicelo; abantu abathile bekholelwa ukuthi lokhu kusebenzisa kwakhe akupheli ngempela. Vele ukufanekisa nobubanzi ukusetshenziswa, singasho ukuthi hydroxide aluminium isetshenziswa njengoba mordant e udayi, purifier amanzi, isithako ezimonyweni, futhi ngisho njengoba isici izinqubo photography. Kukhona futhi izicelo uhlamvu ingane zobumba nokwakhiwa. Kepha insimu ebaluleke kakhulu lapho aluminium hydroxide sisetshenziswa ingumuthi.
Izicelo kwezokwelapha
Ngokuthi aluminium hydroxide uyakwazi iwukudambisa acid, siwulimi antacid zemvelo. Aluminium hydroxide Ubuye impahla iyasiza njengoba kuvusa omzimba womuntu. Ngaphandle, imigomo ehlukahlukene, kuhlanganise nalezo ezingasebenzisi zisetshenziselwa ukwelapha ukusha kwesibindi kohlobo B, ukusha kwesibindi kohlobo A nomhlathi-ngqi, uzilungiselele usebenzisa aluminium hydroxide. Singasho futhi esetshenziselwa ukwelapha izinso iziguli ezingeni lelisetulu phosphate egazini ngenxa yokwehluleka kwezinso. Lesi sici ewusizo ukhona ngenxa ikhono aluminium hydroxide ukuhlanganisa uxhumano nomsebenzisi ne-phosphate. Ngemva ephonsa aluminium hydroxide, phosphate kukhona sikhanyise aphume emzimbeni womuntu kalula.
Izimonyo isicelo
Kukhona izicelo ahlukahlukene aluminium hydroxide emkhakheni izimonyo. Aluminium hydroxide ngokuvamile kakhulu esetshenziswa ukwenziwa lipsticks, ukwenza-ups, kanye neminye imikhiqizo isikhumba ukunakekelwa. Isetshenziselwa khona ngoba uzinzile ngokuphelele futhi okungezona ezinobuthi ngabantu. Ngezinye izikhathi abakhiqizi aluminium hydroxide izimonyo futhi usebenzise aluminium hydroxide ukukhiqiza izinto zokugeza isikhumba ngesikhumba, imikhiqizo suntan, umzimba lotions, futhi moisturizers. Imikhiqizo ukunakekelwa siqu, isibonelo, amashampu, toothpastes, deodorants nabanye abaningi, ukubandakanya futhi usebenzisa aluminium hydroxide. Aluminium hydroxide ngezinye izikhathi isetshenziselwa ukuvikelwa isikhumba womuntu.
Isicelo e umkhakha
Ukhonkolo ayikwazanga ikhiqizwa ngaphandle kwezindleko aluminium hydroxide. Ngokuthi isiphi isigaba sayo ukukhiqizwa ukhonkolo aluminium hydroxide sengezwe usimende. Kuyasiza kakhulu ngoba usimende aluminium hydroxide kwalokho seyomile ngokushesha uma ekuvezweni nokushisa. Ceramics futhi ingilazi kokubili isicelo ezimbonini kanye ekhaya ekhiqizwa usebenzisa aluminium hydroxide. Isici ewusizo kakhulu aluminiyamu hydroxide uma engezwa ingilazi liqukethe yokuthi kwenza ingilazi ukushisa ukumelana. Kungenzeka ngoba, njengoba kufanele iye sekushiwo, aluminium hydroxide akuyona oluvuthayo kanye has okusezingeni eliphezulu ukuma. Aluminium hydroxide kuhlangene polymers libonakala umlilo cishe yizona ezisetshenziswa kabanzi ezinhle kakhulu.
