Kev faib tawm thiab kev siv ntawm zeolite

Ib txwm zeolite yog lub teeb grey lossis nqaij -liab. Vim tias nws cov qauv molecular zoo ib yam li lub scaffold, muaj ntau qhov pores thiab cov channel hauv nruab nrab, nws muaj qhov ntom ntom me me thiab sib dua.
Zeolites tam sim no feem ntau muab faib ua analcime, turbid zeolite, chabazite, calcium philodendronite, heulandite, sodium zeolite, clinoptilolite, mordenite, faujasite, stilbeite, thiab lwm yam. Feem ntau ntawm lawv muaj cov calcium los yog sodium, analcite thiab Chabazite feem ntau yog ib qho khoom siv lead ua, thiab cov khoom siv lead ua 1. phaj- zoo li tus, thiab mordenite yog rab koob - zoo li tus lossis fibrous.
Zeolite muaj ntau yam kev siv, suav nrog kev lag luam, kev tiv thaiv hauv tebchaws, kev ua liaj ua teb, kev yug me nyuam thiab lwm yam kev lag luam.
Zeolites muaj cov khoom xws li adsorption, ion pauv, catalysis, acid tsis kam thiab kub tsis kam, yog li lawv tau dav siv los ua cov khoom sib cais adsorption, ion exchangers thiab catalysts, thiab cov khoom sib xyaw cement.
Hauv kev lag luam roj av thiab tshuaj lom neeg, zeolites yog siv los ua catalytic cracking, hydrocracking, tshuaj isomerization, hloov kho, alkylation, thiab disproportionation ntawm roj av refining; gas thiab kua purification, sib cais thiab cia cov neeg sawv cev; tshwj xeeb desiccants ( cua qhuav, nitrogen, hydrocarbons, thiab lwm yam); thiab siv adsorption thiab ion pauv khoom kom rov qab tau cov khoom hlau, xws li npib tsib xee, tooj liab, cadmium, txhuas, molybdenum, thiab lwm yam, los ntawm cov dej khib nyiab.
Hauv kev lag luam yug me nyuam, ntxiv 5% zeolite hmoov rau pub tuaj yeem pab tsiaj txhu tshem tawm cov teeb meem metabolites hauv cov hnyuv, inhibit qhov kev loj hlob ntawm cov kab mob phem, ncua sij hawm nyob hauv cov hnyuv, thiab txhim kho kev hloov pauv ntawm cov khoom noj; Zeolite hmoov muab tso rau hauv lub tsev yug me nyuam tuaj yeem nqus tau ammonia hauv cov quav thiab ntxuav cov huab cua hauv tsev yug me nyuam, uas tseem muaj txiaj ntsig zoo rau cov nqaij qaib ua liaj ua teb. Kev ua haujlwm ncaj qha rau ntawm cov quav tuaj yeem tiv thaiv kom tsis txhob decomposition thiab fermentation ntawm cov quav, uas pab txhawb kev tsim khoom noj, chiv lossis biogas.
Zeolite tuaj yeem siv los ua cov khoom noj ntxiv (3% -5%) rau cov ntses, cw thiab crabs los txhawb kev loj hlob ntawm cov ntses thiab cws, txhim kho cov kab mob tiv thaiv, thiab tseem muaj txiaj ntsig ntawm kev ua kom huv dej zoo.
