Ua los ntawm kaolin thiab quartz xuab zeb los ntawm kev kub hnyiab, cov cib uas tiv taus kua qaub sawv tawm ua "cuab yeej tiv taus xeb" rau kev lag luam thiab cov xwm txheej tshwj xeeb, ua tsaug rau lawv cov qauv ntom ntom, qhov nqus dej tsawg, thiab kev ruaj khov tshuaj lom neeg muaj zog. Lawv cov ntawv thov npog ntau qhov chaw tseem ceeb.
Hauv kev lag luam kev lag luam, lawv ua haujlwm ua ib qho kev tiv thaiv tseem ceeb. Hauv kev lag luam tshuaj lom neeg, thaum lub sijhawm tsim khoom thiab khaws cia cov kua qaub muaj zog xws li sulfuric acid thiab hydrochloric acid, cov cib uas tiv taus kua qaub yog siv rau hauv pem teb, cov ntaub thaiv reactor, thiab cov thoob dej cia khoom. Lawv tuaj yeem tiv taus kev yaig kua qaub muaj zog, tiv thaiv kev puas tsuaj rau cov khoom siv, ua kom lub neej ua haujlwm ntev, thiab xyuas kom muaj kev nyab xeeb ntawm kev tsim khoom. Hauv cov chaw ua haujlwm hlau, cov xov xwm kua qaub raug tsim thaum lub sijhawm ua cov hlau pickling thiab electrolysis; cov cib uas tiv taus kua qaub tuaj yeem tiv thaiv cov qauv tsev los ntawm kev xeb thiab tswj hwm ib puag ncig ua haujlwm ib txwm muaj hauv chaw ua haujlwm. Rau cov dej khib nyiab kua qaub uas tsim los ntawm lub kaw lus desulfurization hauv cov chaw ua hluav taws xob thermal, cov pas dej kho dej khib nyiab thiab cov pej thuam desulfurization uas muaj cov cib uas tiv taus kua qaub kuj tseem xav tau los cais kev xeb thiab xyuas kom cov khoom siv ua haujlwm ruaj khov.
Hauv cov xwm txheej kev tiv thaiv ib puag ncig, cov cib uas tiv taus kua qaub ua lub luag haujlwm tseem ceeb hauv kev tiv thaiv lub ecosystem. Thaum cov chaw kho dej phwj tuaj yeem tswj cov dej khib nyiab uas muaj kua qaub, cov cib uas tiv taus kua qaub uas muab tso rau hauv cov pas dej tswj thiab cov pas dej ua ke tuaj yeem tiv taus cov dej khib nyiab mus sij hawm ntev thiab kev puas tsuaj ntawm cov tshuaj lom neeg, ua kom ntseeg tau tias cov qauv ntawm cov chaw ua haujlwm muaj kev ncaj ncees thiab tsis muaj kev cuam tshuam rau kev kho dej khib nyiab zoo. Cov dej khib nyiab los ntawm cov chaw kho khib nyiab muaj cov khoom siv kua qaub; cov cib uas tiv taus kua qaub siv hauv cov pas dej sau thiab cov chaw kho dej tuaj yeem tiv thaiv cov dej khib nyiab los ntawm kev ua rau cov tsev puas tsuaj thiab zam kev ua qias tuaj ntawm av thiab dej.
Lawv kuj tseem ceeb heev rau kev tsim kho thiab cov chaw tshwj xeeb. Hauv cov cheeb tsam uas muaj qhov yuav tsum tau tiv thaiv kua qaub, xws li cov chaw kuaj mob thiab cov chaw ua haujlwm ntawm cov chaw tsim tshuaj lom neeg, cov cib uas tiv thaiv kua qaub yog siv ua cov ntaub ntawv hauv pem teb, ua ke tiv thaiv siab, tiv thaiv hnav, thiab cov khoom dai kom zoo nkauj. Rau cov plag tsev thiab phab ntsa ntawm cov chaw ua haujlwm hauv cov chaw tsim khoom noj khoom haus, cov chaw tsim dej haus, thiab cov chaw tsim tshuaj, cov cib uas tiv thaiv kua qaub yog siv vim lawv qhov chaw du thiab yooj yim ntxuav; lawv kuj tuaj yeem tiv taus cov tshuaj tua kab mob acidic thiab ua tau raws li cov qauv kev huv huv.
Kev xaiv cov cib uas tiv taus kua qaub zoo tuaj yeem muab kev tiv thaiv zoo rau ntau qhov xwm txheej sib txawv. Yog tias koj muaj kev xav tau rau kev tiv thaiv xeb hauv kev lag luam, kev tiv thaiv ib puag ncig, lossis kev tsim kho tshwj xeeb, thov koj xav tiv tauj peb. Peb yuav muab cov kev daws teeb meem tshwj xeeb los daws cov teeb meem xeb kom zoo.
