isicelo se-aluminium hydroxide

I-aluminium hydroxide, ekwakhiwe ngayo i-Al(OH)3, inokufumaneka kwindalo ngezi ndlela zilandelayo: i-gibbsite, eyiminerali, kunye ne-doyleite, i-nordstrandite kunye ne-bayerite, zonke ezizii-polymorphs ezinqabileyo. Ngokusekelwe kwiimpawu zayo, singatsho ukuba i-aluminium hydroxide ibonakala iyi-antacid. Inemisebenzi eyahlukeneyo, eyintloko phakathi kwayo kukusetyenziswa kwezonyango.

Iipropati zeKhemikhali

Kukho iintlobo ezininzi ezahlukeneyo ze-aluminium oxide, kuquka zombini iifom ze-crystalline kunye ne-non-crystalline. Sisivikelo sombane, oko kuthetha ukuba asiqhubi umbane, kwaye sikwanayo ne-thermal conductivity ephezulu. Ukongeza, kwimo yaso ye-crystalline,i-corundum, ubulukhuni bayo buyenza ifaneleke njengesiqholo. Iqondo eliphezulu lokunyibilika kwe-aluminium oxide lenza ukuba ibe yinto efanelekileyo yokurhawuzelela izixhobo ezishushu kakhulu ezifana nee-oven, ii-oven, ii-incinerators, ii-reactors ezahlukeneyo, kunye nee-crucibles.

Iimpawu ze-aluminium hydroxide

I-aluminium hydroxide ecociweyo inohlobo lomgubo omkhulu onombala omhlophe okanye iigranules ezinobunzima obuphantse bube yi-2.42 g kwi-mL nganye. I-aluminium hydroxide ayinyibiliki kwi-amanzi, kodwa iya kunyibilika kuphela kwiziseko kunye neeasidi. Ungalindela ukuba i-aluminium hydroxide isebenze njenge-amphoteric substance emanzini. Ukuba kukho isiseko esomeleleyo, i-aluminium hydroxide iya kusebenza njenge-asidi. Kwaye ukuba kukho i-asidi esomeleleyo, iya kusebenza njengesiseko esomeleleyo.
I-aluminium hydroxide kufuneka iphathwe ngononophelo kuba ukuvezwa kwayo kunokubangela ukurhawuzelelwa. Nangona kunjalo, kuya kubakho iingozi ezincinci nezishiyekileyo kuphela. Ngokuphathelele ukutsha, i-aluminium hydroxide ayitshi kwaye ayitshi. Ngaphandle koko, i-aluminium hydroxide ayitshintshi, ngoko ke, izinzile kwiimeko zomlilo kunye namanzi.

Ukusetyenziswa kwe-aluminium hydroxide

I-aluminium hydroxide inezicelo ezininzi; abanye abantu bakholelwa ukuba ezi ndlela zokusetyenziswa azinasiphelo. Ukuze sibonise ububanzi bokusetyenziswa, singathi i-aluminium hydroxide isetyenziswa njenge-mordant kwiidayi, i-purifier ye-amanzi, isithako sezinto zokuthambisa, kwananjengento yeenkqubo zokufota. Kukwakho nokusetyenziswa okuncinci kwi-ceramics nakwizakhiwo. Kodwa eyona ndawo ibalulekileyo apho kusetyenziswa khona i-aluminium hydroxide liyeza.
