Usizo lokuhlunga umhlaba we-Diatomaceous/Diatomaceous
Inombolo ye-CAS: 61790-53-2 (impuphu ene-calcined)
Inombolo ye-CAS: 68855-54-9 (impuphu ehlanganisiwe ene-calcium)
Ukusetshenziswa: Kusetshenziswa embonini yokwenza ubhiya, embonini yeziphuzo, embonini yezemithi, ekucwengisiseni, ekucwengisiseni ushukela, kanye nasembonini yamakhemikhali.
Ukwakheka kwamakhemikhali
Ukwakheka kwamakhemikhali komhlaba we-diatomaceous ikakhulukazi ku-amorphous SiO2, ekhona ngesimo se-SiO2• i-nH2O. SiO2ngokuvamile kubalwa ngaphezu kuka-80%, kuze kufike ku-94%. Iqukethe amanani amancane e-Al2O3, Fe2O3, CaO, MgO, K2O, Na2O, P2O5, nezinto eziphilayo, kanye nokunye ukungcola kwensimbi njenge-Cr ne-Ba. Ukwakheka kanye nokuqukethwe kwezimayini zomhlaba ze-diatomaceous kuyahlukahluka ezindaweni ezahlukene.
Izakhiwo Ezibonakalayo
Umhlaba we-diatomaceous unemibala efana nomhlophe, ompunga omhlophe, ompunga, ompunga okhanyayo, onsundu ompunga okhanyayo, ophuzi okhanyayo, njll. ； Ubuningi: 1.9 ~ 2.3g/cm3；Ubuningi obungu-0.34~0.65g/cm3; Indawo yokuncibilika: 1650 ℃ ~ 1750 ℃; Indawo ethile yobuso engu-19-65cm2/g; Ivolumu yembobo 0.45~0.98cm3/g; Izinga lokumuncwa kwamanzi liphindwe kabili kuya kane kunevolumu yalo. Ukuqina kwamakhemikhali okuphezulu, okungancibiliki ku-hydrochloric acid, okuncibilika kalula ku-alkali, okunezici eziningi ezinhle kakhulu njengokungacindezeleki okulinganiselwe, ukuthamba, ukuvikela umsindo, ukumelana nokuguguleka, kanye nokumelana nokushisa.
Ukuthuthukiswa kanye Nokusetshenziswa
I-diatomaceous earth, ngenxa yezakhiwo zayo ezihlukile ze-physicochemical, isetshenziswe kabanzi njengesihlungi, isigcwalisi esisebenzayo, isithwali se-catalyst, isithwali sezibulala-zinambuzane kanye nomanyolo, izinto zokuvikela, i-adsorbent, kanye nezinto zokukhanyisa.
Usizo lokuhlunga:
I-Diatomaceous earth ingasetshenziswa njengesihlungi sosizo embonini yokudla, yezokwelapha kanye neyezemvelo. Isibonelo, ukusetshenziswa kwe-diatomaceous earth filtration enqubweni yokwenza iwayini kungavuselela njalo umbhede wokuhlunga, isivinini sokuhlunga esisheshayo, isivuno esikhulu； Njengoba inendawo enkulu kanye nomthamo oqinile wokumuncwa, ingahlunga izinhlayiya ezisukela ku-0.1 kuya ku-1.0 μ m, inciphise ukulahlekelwa utshwala cishe ngo-1.4%, futhi ithuthukise izimo zokusebenza kokukhiqiza. Izihlungi zomhlaba ze-Diatomaceous zingathuthukisa kangcono ikhwalithi yamanzi okwelashwa kwamanzi okujikeleza kwechibi lokubhukuda, futhi zingonga amanzi nogesi ekusebenzeni nasekuphathweni kwamachibi okubhukuda. Okwesibili, i-diatomaceous earth nayo isetshenziswe kabanzi emafutheni adliwayo, eziphuzweni zomlomo zemithi, nakweminye imikhakha.
I-Adsorbent：
I-Diatomaceous earth isetshenziswa kabanzi ekuphatheni amanzi angcolile ngenxa yezakhiwo zayo zamakhemikhali ezizinzile, amandla ayo okumunca aqinile, ukusebenza kahle kokuhlunga kanye nokungancibiliki kunoma iyiphi i-asidi enamandla. Ukwelashwa kwangaphambi kokulahla imfucuza kusetshenziswa indlela ye-diatomaceous earth flocculation precipitation kunganciphisa i-CODCr ne-BOD5 ekuleach, kususe ukungcola okufana ne-SS, futhi kusetshenziselwa kakhulu amanzi angcolile asezindaweni zasemadolobheni, ukwenza amanzi angcolile ephepha, ukuphrinta nokudaya amanzi angcolile, ukubulala amanzi angcolile, amanzi angcolile anamafutha, kanye namanzi angcolile ensimbi esindayo.
