Vim yog qhov hnyav ntawm zeolite, ntuj zeolite cov zaub mov tau siv los ua cov khoom siv rau ntau pua xyoo. Tam sim no, zeolite yog yam tshiab ntawm cov khoom siv ib puag ncig zoo, thiab kev lag luam tau tshawb pom cov txiaj ntsig ntawm kev siv cov khoom lag luam zoo/ua kom huv zeolite los tsim cov khoom lag luam muaj txiaj ntsig. Nws qhov txiaj ntsig tsis txwv rau kev tsim cov cement, tab sis kuj tseem siv rau kev ua vaj tse, tshuaj khib, grouting, pleev xim, plaster, asphalt, ceramics, txheej thiab nplaum.
1. Maas, qhob thiab kev tsim kho
Ntuj zeolite ntxhia yog ib yam khoom siv pozzolanic. Raws li European tus qauv EN197-1, cov ntaub ntawv pozzolanic tau muab cais ua ib qho ntawm cov khoom tseem ceeb ntawm cov cement. "Cov ntaub ntawv Pozzolanic yuav tsis tawv thaum sib xyaw nrog dej, tab sis thaum ua av zoo thiab nyob hauv dej, lawv hnov mob nrog Ca (OH) 2 ntawm qhov kub ib puag ncig ib puag ncig los tsim lub zog txhim kho Calcium silicate thiab calcium aluminate sib txuas. Cov sib xyaw no zoo ib yam li cov sib txuas uas tau tsim thaum lub zog ntawm cov khoom siv hydraulic. Pozzolans feem ntau yog tsim los ntawm SiO2 thiab Al2O3, thiab tus so muaj Fe2O3 thiab lwm yam oxides. Qhov feem ntawm cov tshuaj calcium oxide nquag siv rau tawv tuaj yeem tsis quav ntsej. Cov ntsiab lus ntawm silica nquag yuav tsum tsis pub tsawg dua 25.0% (pawg). "
Cov pozzolanic cov khoom thiab cov ntsiab lus silica siab ntawm zeolite txhim kho kev ua haujlwm ntawm cov cement. Zeolite ua raws li kev ruaj ntseg kom nce viscosity, ua tiav kev ua haujlwm zoo dua qub thiab ruaj khov, thiab txo cov tshuaj tiv thaiv alkali-silica. Zeolite tuaj yeem txhim kho qhov nyuaj ntawm cov pob zeb thiab tiv thaiv kev tsim cov kab nrib pleb. Nws yog qhov hloov pauv rau cov cement Portland ib txwm thiab siv los tsim cov sulfate-resistant Portland cement.
Nws yog ib yam ntuj khaws cia. Ntxiv rau sulfate thiab kev tiv thaiv xeb, zeolite tseem tuaj yeem txo cov ntsiab lus chromium hauv cov cement thiab cov pob zeb ua kom zoo, txhim kho tshuaj lom nyob hauv cov dej ntsev siv thiab tiv thaiv kev txhuam hauv dej. Los ntawm kev siv zeolite, cov nyiaj ntxiv ntawm cov cement tuaj yeem txo qis yam tsis muaj zog. Nws pab txo cov nqi tsim khoom thiab txo cov pa roj carbon dioxide tawm thaum lub sijhawm tsim khoom
2. Cov tshuaj pleev xim, txheej txheej thiab cov nplaum
Cov xim pleev xim, xim thiab cov nplaum tau dhau los ua neeg nyiam txhua hnub. Ntuj zeolite cov zaub mov yog ib qho ntawm cov nyiam ntxiv rau cov khoom lag luam ecological. Ntxiv zeolite tuaj yeem muab cov khoom lag luam ib puag ncig zoo thiab muab kev nyab xeeb thiab nyab xeeb ib puag ncig. Vim tias nws muaj peev xwm sib pauv cation siab, zeolite-clinoptilolite tuaj yeem tshem tawm cov ntxhiab tau yooj yim thiab txhim kho huab cua zoo nyob ib puag ncig. Zeolite muaj kev nyiam rau cov ntxhiab tsw ntxhiab, thiab tuaj yeem nqus tau ntau cov pa tsw phem, tsw ntxhiab thiab tsw ntxhiab, xws li: luam yeeb, kib roj, zaub mov lwj, ammonia, dej phwj tuaj, thiab lwm yam.
Zeolite yog lub ntuj desiccant. Nws cov qauv ntxeem tau zoo tso cai rau nws nqus tau txog 50% los ntawm qhov hnyav ntawm cov dej. Cov khoom uas muaj zeolite additives muaj cov pwm ua haujlwm siab. Zeolite tiv thaiv kev tsim cov pwm thiab kab mob. Nws txhim kho qhov zoo ntawm microenvironment thiab huab cua.
3. Asphalt
Zeolite yog hydrated aluminosilicate nrog cov qauv ntxeem tau zoo. Nws yog yooj yim hydrated thiab lub cev qhuav dej. Nws muaj ntau qhov zoo rau sov-sib xyaw asphalt ntawm qhov kub thiab txias: ntxiv zeolite txo qhov kub uas xav tau rau asphalt paving; asphalt sib xyaw nrog zeolite qhia qhov xav tau kom ruaj khov dua thiab muaj zog ntau dua thaum kub dua; Txuag lub zog los ntawm kev txo qhov kub uas xav tau rau kev tsim khoom; txo cov pa roj carbon dioxide tawm hauv cov txheej txheem tsim khoom; tshem tawm ntxhiab, vapors thiab aerosols.
Hauv ntej, zeolite muaj cov qauv ntxeem tau zoo thiab muaj peev xwm sib pauv cation, thiab tuaj yeem siv rau hauv cov khoom lag luam, cov cib, cov rwb thaiv tsev, cov plag tsev thiab cov khoom siv txheej. Raws li cov tshuaj tiv thaiv, zeolite tuaj yeem ua rau lub zog muaj zog, yoog raws thiab ua kom muaj zog ntawm cov khoom, thiab tseem tuaj yeem ua qhov thaiv rau cua sov thiab suab rwb thaiv tsev.
