Aluminium hayidroksayidi, kuqulunqo yayo Al (OH) 3, lungafumaneka kwi lwendalo ezi fom zilandelayo: gibbsite, nto leyo ngezimbiwa, kunye doyleite, nordstrandite kunye bayerite, zonke ezo polymorphs ezinqabileyo. Ngokusekelwe iimpahla zazo, sinokuthi aluminiyam hayidroksayidi kubonakala esesiwini. Kuye isebenzisa ezahlukeneyo, ngowona phakathi apho isicelo zonyango.
Chemical Properties
Kukho iindlela ezahlukeneyo ezininzi aluminiyam oxide, kuquka zombini iintlobo crystalline and non-crystalline. Yeyona i yokwambathisa sombane, nto leyo ithetha ukuba akukho ukuqhuba umbane, kwaye kwakhona iye conductivity eliphezulu thermal. Ukongeza, ekwimo yakhe crystalline, corundum, ngokuba lukhuni yayo kwenza ezifanelekileyo njengento esirhabaxa. Ingongoma yokunyibilika aphezulu aluminiyam oxide kwenza elungileyo eliyinjubaqa eziphathekayo ukuze akhande izixhobo-lobushushu eliphezulu ezifana kilns, amaziko, kwesitovu, zamandla ezahlukeneyo, kunye crucibles.
Iimpawu ze-aluminiyam hayidroksayidi
I-aluminiyam hayidroksayidi lihlanjululwe unomzimba powder enkulu of umbala omhlophe okanye granules kunye mninzi phantse 2,42 g ml nganye. Aluminium hayidroksayidi akayi ukunyibilika emanzini, kodwa liya iyanyibilika kuphela iziseko kunye asidi. Ungalindela aluminiyam hayidroksayidi ukuba asebenze into amphoteric emanzini. Ukuba isiseko esomeleleyo ekhoyo, aluminiyam hayidroksayidi uya kwenza nje acid. Ke ukuba acid enamandla ekhoyo, oko kuya kwenza njengoko kwisiseko esiluqilima.
Aluminium hayidroksayidi kufuneka aphathwe ngokuqaphela kuba sesichengeni wayo kubangele ubuhlungu. Noko ke, kuphela iingozi ezincinane yaye intsalela ziya kubakho. Ke ukuba LINGATSHA, aluminiyam hayidroksayidi ayikho olunokutsha yaye akayi azitshise. Ngapha koko, aluminium hayidroksayidi ayikho lovukelo, ngoko, oko uzinzile kuzo zombini iimeko ngomlilo kunye namanzi.
Izicelo ze-aluminiyam hayidroksayidi
aluminium hayidroksayidi unemisebenzi kwezicelo; abanye abantu bakholelwa ukuba ezi kusebenzisa akupheli ngokwenene. Nje ukuze abonise ebanzi ukusetyenziswa, ukuba uthi hayidroksayidi aluminium kusetyenziswa mordant e iidayi, ocwenga ngamanzi, luyinto izithambiso, kwaye nkqu njengoko njengento kwinkqubo kufota. Kukho kwakhona izicelo unesimilo engephi kwizitya kunye nolwakhiwo. Kodwa ke intsimi ubalulekileyo apho aluminiyam hayidroksayidi lisetyenziswa iyaphilisa.
Izicelo amayeza
Njengoko ukuba aluminiyam hayidroksayidi uyakwazi Nokwethisa asidi, kuba ukhonza esesiwini yendalo. Aluminium hayidroksayidi Kwakhona unalo impahla iluncedo kakhulu njengoko kukhuthaza inkqubo omzimba kwabantu. Ngapha koko, izitofu ezahlukahlukeneyo, kuquka abo ezisetyenziselwa ukunyanga hepatitis B, hepatitis A, nominxano, zilungisiwe kusetyenziswa aluminium hayidroksayidi. Kokuba iphinde isetyenziselwe iinjongo unyango izigulane sezintso abo kwinqanaba eliphezulu phosphate ngegazi ngenxa ukusilela kwezintso. Lo msebenzi osemqoka uluncedo ikhona ngenxa nokukwazi aluminiyam hayidroksayidi ukubophelela kunye phosphate. Emva iyabophelela nge-aluminiyam hayidroksayidi, phosphate ezi ezitum aphume emzimbeni womntu ngokulula.
Isicelo zokuthambisa
Kukho izicelo ezahlukeneyo aluminiyam hayidroksayidi ebaleni zokuthambisa. Aluminium hayidroksayidi ngoyena usetyenziswa rhoqo ekuveliseni lipsticks, yenza-ups, kunye nezinye iimveliso ukunakekelwa isikhumba. Oku kusetyenziswa khona kuba uzinzile ngokupheleleyo kwaye linetyhefu non abantu. Ngamanye amaxesha abenzi aluminium hayidroksayidi of izithambiso kwakhona sebenzisa i-alumuniyam hayidroksayidi ukuvelisa cleansers ulusu, iimveliso elangeni, lotions umzimba, kunye moisturizers. Iimveliso care Personal, umzekelo, ishampu, toothpastes, deodorants kunye nabanye abaninzi, nazo zibandakanya usebenzisa aluminium hayidroksayidi. Aluminium hayidroksayidi kwakhona ngamanye amaxesha isetyenziselwa ukukhusela yesikhumba kwabantu.
Isicelo kushishino
eziphathekayo ayikwazanga kuveliswa ngaphandle aluminium hayidroksayidi. Kwi nqanaba kwimveliso concrete aluminiyam hayidroksayidi igalelwe lwesamente. Kwakhona kuluncedo kakhulu kuba yesamente ye-aluminiyam hayidroksayidi Ukongeza wome ngokukhawuleza xa udibana ukufudumeza. Ukubumba kunye iglasi zombini mveliso kunye nekhaya isicelo yenziwa kusetyenziswa aluminium hayidroksayidi. Lo ngumsebenzi omninzi oluncedo lealuminium hayidroksayidi xa idityaniswa kwiglasi sikuko yokuba wenza ukumelana ubushushu-glass. Oku kuyenzeka kuba, njengokuba sele sele sitshilo, aluminiyam hayidroksayidi ayikho ezinokutsha kwaye ingongoma eliphezulu yokunyibilika. Aluminium hayidroksayidi kudityaniswe Iipholima kubonakala ukuba nekudodobalisa umlilo elungileyo kakhulu.
