izindaba

     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.

     Umhlaba we-Diatomaceousidiphozithiyezinsalela 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. Inokuqina okuhle kwamakhemikhali. Kuyinto ebalulekile yezimboni ezifana nokushisa ukushisa, ukugaya, ukuhlunga, i-adsorption, i-anti-coagulation, i-demoulding, ukugcwalisa, umthwali nokunye. Ingasetshenziswa kabanzi ezimbonini ezifana ne-metallurgy, imboni yamakhemikhali, amandla kagesi, ezolimo, umanyolo, izinto zokwakha kanye nemikhiqizo yokushisa. Ingasetshenziswa futhi njengezihlungi ezisebenzayo zezimboni zamapulasitiki, irabha, izitsha zobumba, nokwenza iphepha.

Isigaba sosizo lwesihlungi se-Diatomite Izinsiza zokuhlunga ze-Diatomite zihlukaniswa ngemikhiqizo eyomisiwe, imikhiqizo e-calcined kanye nemikhiqizo ye-flux calcined ngokwezinqubo ezahlukene zokukhiqiza.

①Umkhiqizo owomile Impahla yobumba yesilica ehlanziwe, yomiswe ngaphambilini futhi igayiwe yomiswa ezingeni lokushisa elingu-600-800°C, bese iyacolwa. Lo mkhiqizo unosayizi wezinhlayiyana ezinhle kakhulu futhi ulungele ukuhlungwa okunembayo. Ivame ukusetshenziswa kanye nezinye izinsiza zokuhlunga. Umkhiqizo owomile uvame ukuphuzi ngokukhanyayo, kodwa futhi umhlophe qhwa kanye nompunga okhanyayo.

②Imikhiqizo enekhalori Izinto zokusetshenziswa ze-diatomite ezihlanziwe, ezomisiwe nezichotshoziwe zifakwa kuhhavini ojikelezayo, zibalwa kumazinga okushisa angu-800-1200°C, bese zichotshozwa futhi zihlukaniswe ukuze kutholwe imikhiqizo ene-calcined. Uma kuqhathaniswa nemikhiqizo eyomile, ukungena kwemikhiqizo e-calcined kungaphezu kokuphindwe kathathu. Imikhiqizo eyenziwe nge-calcined ngokuvamile ibomvu ngokukhanyayo.

③Flux imikhiqizo calcinedNgemuva kokuhlanzwa, ukomiswa nokuchotshozwa, i-diatomite impahla eluhlaza yengezwa ngenani elincane le-sodium carbonate, i-sodium chloride nezinye izinto zokugeleza, bese ibalwa ekushiseni kwe-900-1200 ° C. Ngemuva kokuchotshozwa nokuhlukaniswa kosayizi wezinhlayiyana nokulinganisa, umkhiqizo we-flux calcined uyatholakala. . Ukungena komkhiqizo we-flux calcined kwanda kakhulu, okuphindwe izikhathi ezingaphezu kuka-20 kunomkhiqizo owomile. Imikhiqizo ye-flux calcined ngokuvamile imhlophe, futhi i-pink ekhanyayo uma okuqukethwe kwe-Fe2O3 kuphezulu noma inani lokuguquguquka lilincane.

Umphumela wokuhlunga wosizo lwe-Diatomite

Umphumela wokuhlunga we-diatomite filter aid wenziwa ikakhulukazi ngale misebenzi emithathu elandelayo:

1.Umphumela wokuhlunga

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. Lo mphumela ubizwa ngokuthi ukusefa. Eqinisweni, ingaphezulu lekhekhe lokuhlunga lingabhekwa njengendawo yesisefo enosayizi olinganayo wembotshana ophakathi. Lapho ububanzi bezinhlayiya eziqinile bungekho ngaphansi (noma kancane ngaphansi) ububanzi be-pores ye-diatomite, izinhlayiya eziqinile "zizohlungwa ekumisweni". Hlukanisa ngaphandle, dlala indima yokuhlunga kwendawo.
2. Umphumela ojulile

Umthelela wokujula wumphumela wokugcina wokuhlunga okujulile. Ekuhlungeni okujulile, inqubo yokuhlukanisa iyenzeka kuphela "ngaphakathi" kwendawo. Ingxenye yezinhlayiya ezingcolile ezilinganiselwe ezingena ebusweni bekhekhe lokuhlunga zivinjelwe iziteshi ezincane ezihlukumezayo ngaphakathi komhlaba we-diatomaceous kanye nama-pores amancane ngaphakathi kwekhekhe lokuhlunga. Lolu hlobo lwezinhlayiya luvame ukuba luncane kunama-micropores omhlaba we-diatomaceous. Lapho izinhlayiya zishaya odongeni lwesiteshi, zingase zishiye ukugeleza kwe-liquid. Kodwa-ke, ukuthi ingafinyelela kuleli phuzu kuncike emandleni angenayo kanye nokumelana kwezinhlayiya. Ibhalansi, lolu hlobo lokunqamula kanye nokuhlola kuyafana ngokwemvelo, kokubili kungokwesenzo somshini. Ikhono lokuhlunga izinhlayiya eziqinile ngokuyisisekelo lihlobene kuphela nosayizi ohlobene nokuma kwezinhlayiya eziqinile nezimbotshana.

3.I-Adsorption

Umphumela we-adsorption uhluke ngokuphelele kulezi zindlela ezimbili zokuhlunga ezingenhla. Lo mphumela empeleni ungathathwa njengokukhanga kwe-electrokinetic, okuncike kakhulu endaweni engaphezulu yezinhlayiya eziqinile kanye nomhlaba we-diatomaceous ngokwawo. Lapho izinhlayiya ezinezimbotshana ezincane zangaphakathi emhlabeni we-diatomaceous zishayisana endaweni engaphakathi ye-diatomaceous earth, zikhangwa amacala aphikisanayo, noma izinhlayiya zidonselana ukuze zenze amaqoqo futhi zinamathele emhlabeni we-diatomaceous. Konke lokhu kungumphumela we-adsorption.

Umphumela we-adsorption uyinkimbinkimbi kunemiphumela emibili yangaphambilini. Ngokuvamile kunenkolelo yokuthi isizathu esenza izinhlayiya eziqinile ezincane kunobubanzi bembotshana zibambeke ikakhulukazi ngenxa yalokhu:

(1) Amandla e-Intermolecular (abizwa nangokuthi i-van der Waals attraction), okuhlanganisa i-dipole ehlala njalo, i-dipole eyenziwe kanye ne-dipole esheshayo;

(2) Ukuba khona kwamandla kaZeta;

(3) Inqubo yokushintshanisa i-ion.
