Usizo lwesihlungi se-Diatomiteinesakhiwo esihle se-microporous, ukusebenza kwe-adsorption kanye nokusebenza okuvimbela ukuminyanisa, okungagcini nje ngokwenza uketshezi oluhlungiwe ukuthi luthole isilinganiso esingcono sokugeleza, kodwa futhi luhlunga okuqinile okumisiwe okuqinile ukuze kuqinisekiswe ukucaca. I-Diatomaceous Earth iyidiphozithi yezinsalela zama-diatom asendulo aneseli elilodwa. Izici zayo: isisindo esilula, i-porous, amandla aphezulu, ukumelana nokugqoka, ukwahlukanisa, ukushisa ukushisa, i-adsorption nokugcwalisa nokunye ukusebenza okuhle kakhulu. Namuhla, i-Junlian diatomite izokwengeza i-several izindlela ezahlukene zokuhlunga ze-diatomite filter aid.

Usizo lwesihlungi se-diatomite luvalela ngokuyinhloko izinhlayiya zokungcola okuqinile ezimiswe oketshezini endaweni ephakathi nendawo kanye nesiteshi ngemisebenzi emithathu yokuhlola, umphumela wokujula, kanye ne-adsorption, ukuze kufezwe injongo yokuhlukaniswa koketshezi oluqinile.

1. Umphumela wokuhlola i-Diatomite: Lona umphumela wokuhlunga okungaphezulu. Lapho uketshezi lugeleza emhlabeni we-diatomaceous, ama-pores omhlaba we-diatomaceous mancane kunosayizi wezinhlayiya zezinhlayiya ezingcolile, ukuze izinhlayiya zokungcola zingakwazi ukudlula futhi zinqamule. Umphumela ubizwa ngokuthi umphumela wokuhlola.

2. Umphumela wokujula we-Diatomite: Umthelela wokujula umphumela wokugcinwa kokuhlunga okujulile. Ekuhlungeni okujulile, inqubo yokuhlukanisa iyenzeka kuphela "ngaphakathi" kwendawo. Ingxenye yezinhlayiya ezincane zokungcola ezingena ebusweni bekhekhe lokuhlunga zimbozwe i-diatomite. Isakhiwo sangaphakathi se-tortuous microporous kanye nezimbotshana ezincane ngaphakathi kwekhekhe lokuhlunga zivinjelwe. Izinhlayiya ezinjalo ngokuvamile zincane kunama-micropores omhlaba we-diatomaceous. Lapho izinhlayiya zishaya odongeni lwesiteshi, zingase zishiye ukugeleza kwe-liquid. Kodwa-ke, ukuthi ingakwazi yini ukufeza lokhu kuncike ekulinganiseni kwamandla angenayo kanye nokumelana nezinhlayiya. Lokhu kunqamula nokuhlola kuyafana ngokwemvelo, futhi kokubili kungokwemiphumela yemishini. Ikhono lokuhlunga izinhlayiya eziqinile ngokuyisisekelo lihlobene kuphela nosayizi ohlobene nokuma kwezinhlayiya eziqinile nezimbotshana.

3. I-Diatomite adsorption: I-adsorption empeleni ingathathwa njengokukhanga kwe-electrokinetic, okuncike kakhulu endaweni engaphezulu yezinhlayiya eziqinile kanye ne-diatomite ngokwayo. Indawo yephoyinti yomhlaba we-diatomaceous inegethivu, inani eliphelele likhulu, futhi lingakhanga ngempumelelo amashaji avumayo. Lapho izinhlayiya ezincane kunezimbotshana zangaphakathi zomhlaba we-diatomaceous zishayisana endaweni engaphakathi ye-diatomaceous earth, zikhangwa amashaji kagesi. Kukhona futhi uhlobo lokukhangana phakathi kwezinhlayiya ukuze zakhe amaqoqo futhi zinamathele emhlabeni we-diatomaceous. Kokubili kungokwe-adsorption, futhi i-adsorption iyinkimbinkimbi kakhulu kunemiphumela emibili yangaphambilini. Ngokuvamile kunenkolelo yokuthi isizathu esenza izinhlayiya eziqinile ezincane kunobubanzi bembotshana zibambeke ikakhulu ngenxa yalokhu: amandla e-intermolecular (abuye abizwe ngokuthi i-van der Waals attraction), okuhlanganisa i-dipole engapheli, i-dipole eyenziwe, i-dipole esheshayo kanye nokuba khona kwenqubo yokushintshanisa i-Ion engaba khona.
