Aluminium hydroxide, uas yog Al(OH)3, muaj nyob rau hauv xwm hauv cov ntawv hauv qab no: gibbsite, uas yog ib qho mineral, thiab doyleite, nordstrandite thiab bayerite, uas yog cov polymorphs tsis tshua muaj. Raws li nws cov khoom, peb tuaj yeem hais tias aluminium hydroxide zoo li yog antacid. Nws muaj ntau yam kev siv, thawj qhov yog kev siv kho mob.
Cov Khoom Siv Tshuaj
Muaj ntau hom txhuas oxide sib txawv, suav nrog ob qho tib si crystalline thiab non-crystalline. Nws yog ib qho insulator hluav taws xob, uas txhais tau tias nws tsis coj hluav taws xob, thiab nws kuj muaj cov thermal conductivity siab. Tsis tas li ntawd, nyob rau hauv nws daim ntawv crystalline,corundum, nws qhov nyuaj ua rau nws tsim nyog ua cov khoom siv abrasive. Lub ntsiab lus siab ntawm txhuas oxide ua rau nws yog cov khoom siv refractory zoo rau kev sib txuas cov khoom siv kub siab xws li kilns, furnaces, incinerators, reactors ntawm ntau hom, thiab crucibles.
Cov khoom ntawm txhuas hydroxide
Cov txhuas hydroxide uas tau lim lawm muaj cov hmoov loj dawb lossis cov granules nrog qhov ceev ze li ntawm 2.42 g ib mL. Txhuas hydroxide yuav tsis yaj rau hauvdej, tab sis yuav yaj tsuas yog nyob rau hauv cov hauv paus thiab cov kua qaub. Koj tuaj yeem cia siab tias txhuas hydroxide yuav ua haujlwm ua cov tshuaj amphoteric hauv dej. Yog tias muaj cov hauv paus muaj zog, txhuas hydroxide yuav ua haujlwm ua cov kua qaub. Thiab yog tias muaj cov kua qaub muaj zog, nws yuav ua haujlwm ua cov hauv paus muaj zog.
Yuav tsum tau ceev faj thaum siv aluminium hydroxide vim tias nws qhov kev raug yuav ua rau khaus. Txawm li cas los xij, tsuas yog muaj kev raug mob me me thiab cov seem xwb. Raws li qhov yooj yim kub hnyiab, aluminium hydroxide tsis yooj yim kub hnyiab thiab yuav tsis kub hnyiab. Dhau li ntawd, aluminium hydroxide tsis tshua muaj zog, yog li ntawd, nws ruaj khov hauv ob qho tib si hluav taws thiab dej.
Cov ntawv thov ntawm txhuas hydroxide
Aluminium hydroxide muaj ntau daim ntawv thov; qee tus neeg ntseeg tias cov kev siv no tsis muaj qhov kawg. Tsuas yog los piav qhia txog qhov dav ntawm kev siv, peb tuaj yeem hais tias aluminium hydroxide yog siv ua mordant hauv dyes, purifier raudej, cov khoom xyaw rau cov tshuaj pleev ib ce, thiab txawm tias ua ib qho khoom siv rau cov txheej txheem hauv kev thaij duab. Kuj tseem muaj cov ntawv thov ntawm cov cim me me hauv cov khoom siv ceramics thiab kev tsim kho. Tab sis qhov chaw tseem ceeb tshaj plaws uas siv txhuas hydroxide yog tshuaj.
