Litšobotsi tsa microstructure tsa diatomite

Sebopeho sa lik'hemik'hale tsa lefats'e la diatomaceous haholo-holo ke SiO2, empa sebopeho sa eona ke amorphous, ke hore, amorphous. SiO2 ena ea amorphous e boetse e bitsoa opal. Ha e le hantle, ke SiO2 e nang le metsi amorphous colloidal, e ka hlalosoang e le SiO2⋅nH2O. Ka lebaka la libaka tse fapaneng tsa tlhahiso, metsi a fapane; microstructure ea lisampole tsa diatomite e amana haholo le mefuta ea li-diatom tse behiloeng. Ka lebaka la mefuta e fapaneng ea li-diatom, sebopeho sa microscopic se entsoeng ka diatomite ore Ho na le phapang e hlakileng ea sebopeho, kahoo ho na le phapang ea ts'ebetso. Se latelang ke depositi ea diatomite e entsoeng haholo-holo ke li-deposit tsa lefats'e sebakeng se itseng naheng ea rona eo re ithutileng eona, 'me li-diatoms li na le linear haholo.

Tšebeliso ea diatomite

Ka lebaka la microstructure e ikhethang ea diatomite, e na le mefuta e mengata ea lisebelisoa likarolong tse ngata tse kang thepa ea mohaho, lik'hemik'hale, temo, ts'ireletso ea tikoloho, lijo le theknoloji e phahameng. Japane, 21% ea lefats'e la diatomaceous e sebelisoa indastering ea thepa ea kaho, 11% e sebelisoa ka thepa ea refractory, 'me 33% e sebelisoa ho bajari le li-filler. Hajoale, Japane e fihletse litholoana tse ntle ntlafatsong le ts'ebelisong ea thepa e ncha ea moaho.

Ka kakaretso, lits'ebetso tsa mantlha tsa diatomite ke:

(1) Sebelisa sebopeho sa eona sa microporous ho lokisa lisebelisoa tse fapaneng tsa filthara le litšehetso tse thusang. Ena ke e 'ngoe ea litšebeliso tsa mantlha tsa lefats'e la diatomaceous. E sebelisa ka botlalo litšobotsi tsa microstructure tsa lefatše la diatomaceous. Leha ho le joalo, ore ea lefats'e ea diatomaceous e sebelisoang e le thuso ea ho sefa ka ho khetheha e ruile ka li-corinosites, 'me majoe a lefats'e a diatomaceous a nang le sebopeho sa linear algae e le catalyst carrier e molemo hobane li-linear algae li na le bokaholimo bo boholo ba ka hare.

(2) Tokisetso ea ho boloka mocheso le lisebelisoa tsa refractory. Har'a lisebelisoa tsa ho kenya mocheso tse ka tlase ho 900 ° C, litene tse thibelang mocheso oa diatomite ke khetho e nepahetseng ka ho fetisisa, eo hape e leng e 'ngoe ea masimo a ka sehloohong a kopo ea merafo ea diatomite naheng ea heso.

(3) Lefatše la Diatomaceous le ka sebelisoa e le mohloli o ka sehloohong oa SiO2 e sebetsang. Kaha SiO2 lefatšeng la diatomaceous ke amorphous, e na le ts'ebetso e phahameng. Ka mohlala, ho loketse haholo ho e sebelisa ho itšoara ka lisebelisoa tse tala tsa calcareous ho lokisetsa lisebelisoa tse thibelang mollo tsa calcium silicate board. Ha e le hantle, litšila tse ling li lokela ho tlosoa ore ea diatomite ea boemo bo tlaase.

(4) Sebelisa litšobotsi tsa eona tsa microporous adsorption ho lokisetsa li-antibacterial le antifungal agents. Ena hape ke e 'ngoe ea lits'ebetso tse ncha tsa bohlokoa tsa diatomite, e leng sesebelisoa se sebetsang se nang le litlamorao tsa tikoloho. Bolelele ba bacillus ka kakaretso ke 1-5um, bophara ba cocci ke 0.5-2um, 'me boholo ba pore ea lefats'e la diatomaceous ke 0.5um, kahoo karolo ea filthara e entsoeng ka lefats'e ea diatomaceous e ka tlosa likokoana-hloko, haeba e khomaretsoe ho diatomaceous earth filter element Antibacterial agents le photosensitizers ba na le liphello tse molemo tsa ho thibela likokoana-hloko le lisebelisoa tse ling tsa bactericidal. sepheo sa ho lokolla butle le litlamorao tsa nako e telele. Hona joale, batho ba ka sebelisa mekhoa e phahameng ea theknoloji ho lokisa diatomaceous earth-type-anti-midew le lisebelisoa tse sebetsang tse thibelang likokoana-hloko ka lefats'e la diatomaceous e le mojari.
