Kev piav qhia ntawm cov roj hmab hauv ob sab phlu


I. qauv khoom

Cov kab txaij qaub ncaug yog ib lub me me tshwj xeeb ntawm cov roj hmab (alumina) nyob hauv cov roj hmab tshwj xeeb, ib txoj hlua khau uas tawv tsis sib haum, tom qab siv cov hluav taws xob uas muaj zog ua daim nplaum rau hauv cov cuab yeej hauv plhaub, daim ntawv hlau ua kom muaj zog thiab buffers hnav txheej, tam sim no yog qhov khoom zoo tshaj plaws.

Ii. Khoom siv

Nws yog dav siv nyob rau hauv cov tshuab xa hluav taws xob hluav taws xob cog hluav taws xob, kev siv hluav taws xob thiab cov tshuab hlau, cov khoom siv hauv tshuab raj thiab lub raj qhwv, thiab lwm yam. Cov kab ntsig yuav ua tau thiab txiav, tsim nyog rau kev teeb tsa ntawm tag nrho cov hom khoom tshwj xeeb, thiab dej thiab qaug zog acid thiab alkali tsis kam. Tab sis rau cov roj hmab laus ntawm kev kub siab, txwv nyob rau hauv 100 ℃ kub cheeb tsam siv.
