Zeolite yog ib qho ore, uas tau pom thawj zaug hauv 1756. Swedish mineralogist Axel Fredrik Cronstedt tau tshawb pom tias muaj ib hom ntuj aluminosilicate ore uas kub hnyiab thaum kub hnyiab, yog li nws lub npe hu ua "zeolite" (Swedish zeolit). "Pob zeb" (lithos) lub ntsiab lus "rhaub" (zeo) hauv Greek. Txij thaum ntawd los, tib neeg kev tshawb fawb txog zeolite tau txuas ntxiv mus tob dua.
Cov tshuaj lom neeg dav dav ntawm zeolite yog: AmBpO2p · nH2O, thiab cov qauv txheej txheem yog A (x/q) [(AlO2) x (SiO2) y] · n (H2O) qhov twg: A yog Ca, Na, K, Ba, Sr thiab lwm cov cations, B Yog Al thiab Si, p yog qhov muaj nuj nqis ntawm cations, m yog tus lej cation, n yog tus naj npawb ntawm cov dej molecules, x yog tus lej ntawm Al atoms, y yog tus lej Si atoms, ( y/x) feem ntau yog nruab nrab ntawm 1 thiab 5, (x+y) Puas yog tus lej ntawm tetrahedrons hauv chav nyob ntawm tes.
Molecular phaus: 218.247238
Zeolite muaj cov khoom sib pauv ion, kev nqus thiab cais cov khoom, cov khoom siv catalytic, kev ruaj ntseg, tshuaj lom neeg rov ua dua, rov ua kom lub cev qhuav dej, rov ua hluav taws xob thiab lwm yam. Zeolite feem ntau yog tsim los ntawm qhov tawg lossis amygdala ntawm cov pob zeb tawg, sib koom ua ke nrog calcite, chalcedony, thiab quartz; nws kuj tseem tsim tawm hauv cov pob zeb pyroclastic sedimentary thiab cov tso dej kub caij nplooj ntoo hlav.
Zeolite ore tau siv dav hauv
1.Adsorbent thiab desiccant
2.catalyst
3.Detergent
4.Kev siv lwm yam (kho dej phwj tuaj, hloov kho av, pub ntxiv tshuaj ntxiv)
Ntuj Zeolite ore yog cov khoom tsim tawm, uas tau siv dav hauv kev lag luam, kev ua liaj ua teb, kev tiv thaiv hauv tebchaws thiab lwm yam haujlwm, thiab nws siv tseem tab tom tshawb nrhiav. Zeolite yog siv los ua cov khoom sib pauv ion, adsorption sib cais tus neeg sawv cev, desiccant, catalyst, xis mas sib tov khoom. [7] Hauv cov roj av thiab tshuaj lom neeg kev lag luam, nws tau siv los ua catalytic tawg, hydrocracking, thiab tshuaj isomerization, hloov kho, alkylation, thiab tsis sib xws ntawm cov roj av; roj thiab kua ua kom huv, sib cais thiab khaws cia cov neeg sawv cev; dej ua kom tawv muag, Cov dej hiav txwv desalination tus neeg sawv cev; tshwj xeeb desiccant (cua qhuav, nitrogen, hydrocarbons, thiab lwm yam). Hauv kev lag luam teeb, nws tau siv hauv kev ua papermaking, roj hmab hluavtaws, yas, yas, cov xim pleev xim thiab xim zoo. Hauv kev tiv thaiv hauv tebchaws, thaj chaw thev naus laus zis, thev naus laus zis nqus tshuab, txhim kho lub zog, kev lag luam hluav taws xob, thiab lwm yam, nws tau siv los ua cov khoom sib cais adsorption thiab desiccant. Hauv kev tsim cov khoom lag luam hauv tsev, nws tau siv los ua cov cement ua kom muaj zog sib xyaw kom hlawv cov khoom sib sib zog nqus kom ua rau lub teeb thiab lub zog muaj zog cov phaj thiab cov cib. Siv ua cov av txias hauv kev ua liaj ua teb, nws tuaj yeem tiv thaiv chiv, dej, thiab tiv thaiv kab tsuag thiab kab mob. Hauv kev lag luam tsiaj txhu, nws tuaj yeem siv ua khoom noj (npua, qaib) ntxiv thiab deodorants, thiab lwm yam, uas tuaj yeem txhawb kev loj hlob ntawm cov tsiaj txhu thiab ua kom muaj sia nyob ntawm cov qaib. Hais txog kev tiv thaiv ib puag ncig, nws tau siv los kho cov pa nkev thiab cov dej tsis zoo, tshem tawm lossis rov ua cov hlau ions los ntawm cov dej khib nyiab thiab cov kua pov tseg, thiab tshem cov pa phem uas muaj kuab paug hauv cov dej khib nyiab.
Hauv tshuaj, zeolite tau siv los txiav txim siab tus nqi nitrogen hauv cov ntshav thiab cov zis. Zeolite kuj tseem tau tsim los ua cov khoom noj qab haus huv rau kev tiv thaiv kev laus thiab tshem tawm cov hlau hnyav uas tau sau hauv lub cev.
Hauv kev tsim khoom, zeolite feem ntau siv hauv kev ua kom zoo ntawm cov suab thaj granulated.
