Qhov txawv ntawm Aluminium Hydroxide Thiab Alumina

Aluminium hydroxide yog ua los ntawm bauxite, ua tiav los ntawm cov txheej txheem tshwj xeeb kom tau txais cov ntaub ntawv raw, thiab tom qab ntawd calcined kom tau txais alumina. Yog li ntawd, cov khoom siv raw rau qhov kev ntsuas no yog tib yam, thiab lawv yog cov sib txuas sib txawv hauv tib txoj kev tsim khoom, yog li dab tsi yog qhov txawv ntawm ob? Cia peb ua raws li cov kauj ruam ntawm tus editor kom pom.

Hauv qab no peb feem ntau nkag siab txog lawv qhov sib txawv ntawm ob yam: lub cev thiab cov khoom siv tshuaj lom neeg:

1. Lub cev muaj zog: Alumina yog cov khoom dawb, dej-insoluble nrog lub siab melting point. Aluminium hydroxide yog cov khoom dawb colloidal, insoluble hauv dej, thiab muaj zog adsorption, uas tuaj yeem nqus cov khib nyiab thiab ntau yam xim hauv dej.

2. Cov khoom siv tshuaj lom neeg: Alumina yog ib qho amphoteric oxide, uas tsis hnov ​​​​mob nrog dej, thiab tuaj yeem ua rau cov kua qaub thiab alkalis; aluminium hydroxide yog tshuaj tsis ruaj khov, yooj yim decomposed thaum rhuab, insoluble nyob rau hauv tsis muaj zog acids thiab tsis muaj zog bases, tab sis soluble nyob rau hauv qaug zog acids thiab bases. Hauv cov kua qaub muaj zog thiab muaj zog hauv paus, qhov no feem ntau siv los txheeb xyuas Al (OH) 3.

3. Siv: Alumina feem ntau yog siv rau kev kub siab refractories, thiab lwm yam .; thiab aluminium hydroxide muaj cov txiaj ntsig zoo hauv ntau yam kev lag luam roj thiab tshuaj.
