Taw qhia: Cov khoom siv lim dej feem ntau yog hais txog cov ntaub ntawv ntau siv rau kev lim dej, feem ntau hu ua quartz xuab zeb, dawb thee lossis ore. Lwm hom yog lub nruab nrab lim lub nruab nrab.
Daim Ntawv Thov: Nws yog siv rau ib-txheej lim, ob txheej-lim lim, ob txheej-lim lim, ion exchanger, thiab lwm yam kom txhawm rau nruab nrab thiab lub ncoo hauv cov khoom siv, los cuam tshuam nrog ntau yam kev lim dej, kev lag luam dej, dej phwj hauv nroog thiab lwm yam.
Kev faib tawm
1.Membrane lim cov khoom siv: microporous film clad lim cov khoom siv (cov xim lim cov khoom siv) yog ua los ntawm polytetrafluoroethylene. Qhov saum npoo ntawm polytetrafluoroethylene zaj duab xis yog du thiab muaj tshuaj lom neeg, thiab nws yog laminated rau saum npoo ntawm cov khoom siv lim zoo ib yam. Nws ua raws li txheej txheej uas muaj plua plav pov tseg, thiab txhua plua plav tau khuam rau saum npoo av kom ua tiav cov quav pom. Kev sib txuam tsis zoo dua qub nrog cov ntaub ntawv lim.
2.Coke lim cov khoom siv: cov tshuab muaj zog, siab porosity, zoo adsorption kev ua tau zoo, muaj peev xwm cuam tshuam zoo, tshem tawm cov khib nyiab hauv dej, ntxuav cov dej muaj cov txiaj ntsig zoo, dav siv hauv kev kho dej muaj dej.
3.Porcelain pob: Sab saum npoo yog qhov nyuaj, sab hauv yog microporous, kev pab lub neej ntev, thiab lub zog tshwj xeeb yog nruab nrab. Siv dav hauv ib txheej-lim lim, ob txheej-lim lim, lim peb-txheej txheej, thiab lwm yam lim.
4.Manganese sand lim cov khoom siv: Nws muaj cov hlau zoo thiab manganese tshem tawm cov txiaj ntsig thiab feem ntau siv rau hauv cov hlau thiab manganese tshem tawm cov khoom siv rau cov dej haus.
5.Activated carbon plhaub: Nws yog ua los ntawm cov txiv ntoo zoo lub plhaub (plhaub apricot, lub plhaub taum txiv ntoo, lub plhaub taum txiv ntoo). Nws tau tsim cov qauv khoob khoob khoob khoob, thaj chaw loj tshwj xeeb thaj chaw, muaj zog adsorption kev ua tau zoo, siab txhua yam muaj zog, txaj txaj me me thiab cov tshuaj ua kom ruaj khov. Yooj yim rau kev tsim dua tshiab, kav ntev thiab lwm yam.
6.Coconut plhaub ua kom cov pa roj carbon monoxide: tsim nyob hauv cov qauv tsis muaj txheej txheem, thaj chaw loj tshwj xeeb thaj chaw thiab muaj zog adsorption kev ua tau zoo, dav siv nyob rau hauv ntau cov dej ua kom huv, kub rho tawm, tshuaj tua hluav taws.
Coal-like columnar activated carbon: tsim pore qauv, thaj chaw loj hauv cheeb tsam, muaj zog adsorption kev ua tau zoo, siab zog thiab rov ua dua tshiab.
7.Anthracite lim cov khoom siv: Nws yog cov lim dej lim cov khoom siv lim dej zoo tshaj plaws uas siv hauv Suav teb. Nws muaj cov cuab yeej tshuaj lom neeg ruaj khov, tsis yog soluble nyob rau hauv dav dav acidic, nruab nrab thiab alkaline dej, thiab muaj lub zog ntawm cov neeg ua haujlwm txaus. Nws yog tam sim no ib txheej, ob chav txheej, Cov ntaub ntawv zoo uas yog qhov tseem ceeb hauv peb-txheej lim
