Ntuj zeolite: nta, nta, Muaj Siv

Zeolite hais txog ib tug pab pawg neeg ntawm sedimentary minerals ntawm volcanic keeb kwm, muaj ib tug plurality ntawm cov yam ntxwv hom. Cov nram qab no yog cov feem ntau tej yam ntuj tso zeolites: lomonit, erionite, ferrierite, chabazite thiab lwm tus neeg. Los ntawm lub standpoint ntawm Science News for KIDS, zeolites yog non-stoichiometric tebchaw siv lead ua qauv. Lub cim thaj chaw ntawm cov mineral nkaus vim lub internal qauv - ob peb ua ke vertices tetrahedra txhuas oxide thiab silicon daim ntawv heev heev raws sau nrog dej lwg me me, thiab zoo them hais.

Zoo cov yam ntxwv ntawm zeolites paub txog ntau pua xyoo. Nyob rau hauv ancient sij hawm cov neeg tau ntxiv zeolite-muaj pob zeb nyob rau hauv cov zaub mov, paub txog lub hwj chim kho mob ntawm cov zaub mov. Centuries dhau los tillers pom hais tias cov qoob loo nyob rau hauv daim av richer nrog deposits ntawm zeolite.

Kom txog rau thaum nyuam qhuav, lub industrial zus tau tej cov ntuj zeolite twb tsis ua, lub tsim minerals siv - hluavtaws zeolites. Kev siv cov zeolites yog raws li nyob rau hauv cov tshuaj thiab lub cev thaj chaw ntawm cov mineral. Ua ntej ntawm tag nrho - nws yog ib tug natural adsorbent. Lub cev qhuav dej yog hloov dua siab tshiab rau hauv ib lub microporous mineral kwv nrog nrog kab noj hniav system, uas muaj peev xwm txeem lub lwg me me ntawm cov organic thiab inorganic tebchaw. Nws possesses siab ntxeem tau dej muaj peev xwm los ntawm soaking ntau gases thiab kua.

Zaum tau launched ib tug kev tshawb fawb ntawm lom, lub cev thiab tshuaj thaj chaw ntawm cov zaub mov rau lub hom phiaj uas muaj daim ntaub ntawv. Nyob rau hauv cov zaub mov thiab ua liaj ua teb kev lag luam, zeolites yog siv rau zus tau tej tus phooj ywg environmentally khoom. Lub ntsiab rau daim ntawv thov ntawm zeolite:

• nyob rau hauv cov tsiaj txhu, qaib, raws li ib tug pub additive nyob rau hauv lub pub, deodorizing Improvement rau nyuj;
• raws li ib tug lim caij nyob rau hauv Workers dej purification systems;
• rau adsorption ntawm tej yam tshuaj lom;
• nyob rau hauv cov kev kho mob uas muaj wastewater;
• nyob rau hauv kev ua lag luam - zus tau tej cov pob zeb, MAAs, roj hmab, roj hmab, daim ntawv thiab cov duab los qhia;
• nyob rau hauv cov tshuaj raws li hemosorbents thiab lwm yam sorption technologies.

Lub ntiaj teb no ntim ntawm zeolite ntau lawm yog loj hlob txhua xyoo los ntawm 20-25%. Ua ntawm zeolite rau ib tug muaj scale yog nqa tawm nyob rau hauv tag nrho cov ntawm mineral deposits. Yog li tsuas yog ib feem ntawm lub tso nyiaj yog mined pob zeb mus rau lub ntsiab lus ntawm lub active constituent ntawm txog 60%. Yeej no daim duab tsis sawv saum toj no 50%. Yog li, siv cov zeolite minerals nyob rau hauv ntau yam industries ua efficiency yog txiav txim los ntawm ib tug loj feem pua ntawm cov active ingredient.
