CAS #: 61790-53-2 (pa'u pa'u)
CAS #: 68855-54-9 (fa'afefiloi calcined pauta)
Fa'aoga: Fa'aaogaina i totonu o le fale gaosi oloa, mea inu meainu, falema'i vaila'au, fa'amamaina, suka suka, ma vaila'au vaila'au.
Su'ega vaila'au
O le vaila'au o le eleele diatomaceous e tele lava amorphous SiO2, o loʻo i ai i foliga o le SiO2• nH2O. SiO2e masani ona sili atu i le 80%, e oʻo atu i le 94%. O lo'o i ai ni vaega laiti o Al2O3, Fe2O3, CaO, MgO, K2O, Na2O, P2O5, ma mea faʻaola, faʻapea foʻi ma nisi o mea leaga e pei o le Cr ma le Ba. O le tuufaatasiga ma mea o loʻo i totonu o mines eleele diatomaceous e eseese i itulagi eseese.
Meatotino Faaletino
O le eleele diatomaceous e iai lanu e pei o le paʻepaʻe, efuefu paʻepaʻe, efuefu, lanu efuefu, lanu enaena lanu enaena, lanu samasama, ma isi; Density: 1.9~2.3g/cm3； Tulaga tele 0.34~0.65g/cm3; Liu liusuavai: 1650 ℃ ~ 1750 ℃; Fa'apitoa o luga ole 19-65cm2/g; Pore voluma 0.45~0.98cm3/g; Ole fua ole vai ole 2-4 taimi o lona lava voluma. Maualuluga kemikolo mautu, insoluble in hydrochloric acid, faigofie soluble i alkali, ma le tele o mea lelei e pei o le incompressibility, vaivai, leo insulation, ofu tetee, ma le vevela.
Atina'e ma Fa'aoga
O le eleele diatomaceous, ona o ona uiga faʻapitoa faʻapitoa, ua faʻaaogaina lautele e avea o se fesoasoani faamama, faʻatumu galuega, faʻapipiʻi faʻamaʻi, vailaau faʻasaina ma fetilaisa, mea faʻapipiʻi, adsorbent, ma mea faʻafefe.
Fesoasoani fesoasoani:
E mafai ona fa'aogaina le eleele diatomaceous e fai ma fesoasoani faamama i mea'ai, vaila'au, ma pisinisi tau si'osi'omaga. Mo se faʻataʻitaʻiga, o le faʻaogaina o le faʻaogaina o le eleele diatomaceous i le faʻagasologa o le uaina e mafai ona faʻafou pea le moega faamama, vave filtration saoasaoa, fua tele; Faʻatasi ai ma le tele o luga o le eleele ma le malosi o le adsorption malosi, e mafai ona faʻamama ese vaega mai le 0.1 i le 1.0 μm, fa'aitiitia le 'ava mālosi e tusa ma le 1.4%, ma fa'aleleia tulaga fa'agaioia o le gaosiga. Diatomaceous eleele faamama e mafai ona sili atu le faaleleia o le tulaga vai o le vai ta'ele fa'asalalau vai togafitiga, ma mafai ona fa'asaoina le vai ma le eletise i le fa'agaioiga ma le pulega o vaita'ele. Lona lua, o le eleele diatomaceous ua faʻaaogaina lautele i suauʻu meaʻai, vailaʻau oral vai, ma isi fanua.
Adsorbent:
E masani ona faʻaaogaina le lalolagi diatomaceous i le faʻaaogaina o vai otaota ona o lona mautu vailaʻau, malosi malosi adsorption, lelei filtration faatinoga ma insolubility i so o se malosi malosi. O le togafitiga muamua o le lapisi lapisi e faʻaaoga ai le diatomaceous earth flocculation precipitation method e mafai ona faʻaitiitia le CODCr ma le BOD5 i le leachate, aveese mea filogia e pei o le SS, ma e masani lava ona faʻaaogaina mo vai otaota i le taulaga, fai pepa vai otaota, lolomi ma vali vai otaota, fasia otaota, suauʻu suavai. , ma vai leaga uamea mamafa.
