Iyini i-Diatomite Filter Aid?

I-Diatomite Filter Aid inesakhiwo esihle se-microporous, ukusebenza kwe-adsorption, nokusebenza kwe-anti compression. Abakwazi nje ukuzuza isilinganiso esihle sokugeleza koketshezi oluhlungiwe, kodwa futhi bahlunge izinto eziqinile ezimisiwe, eziqinisekisa ukucaca. I-Diatomaceous Earth iyinhlabathi yezinsalela ze-diatom zeseli elilodwa lasendulo. Izici zayo zifaka isisindo esilula, i-porosity, amandla aphezulu, ukumelana nokugqoka, ukwahlukanisa, ukufakwa kwe-thermal, i-adsorption, nokugcwalisa, phakathi kwezinye izakhiwo ezinhle kakhulu.

Inokuqina okuhle kwamakhemikhali. Kuyinto ebalulekile yezimboni yokufakelwa, ukugaya, ukuhlunga, i-adsorption, i-anticoagulation, i-demolding, ukugcwalisa, kanye ne-carrier. Ingasetshenziswa kabanzi ezimbonini ezifana ne-metallurgy, imboni yamakhemikhali, amandla kagesi, ezolimo, umanyolo, izinto zokwakha kanye nemikhiqizo yokufakelwa. Ingasetshenziswa futhi njengezihlungi ezisebenzayo zezimboni zamapulasitiki, irabha, izitsha zobumba, ukwenza amaphepha, nezinye izimboni.

Ukwahlukanisa

I-Diatomite Filter Aidare ihlukaniswe yaba imikhiqizo eyomisiwe, imikhiqizo ehlanganisiwe, kanye nemikhiqizo ye-flux calcined ngokuya ngezinqubo ezahlukene zokukhiqiza.

①Imikhiqizo eyomile

Yomisa inhlabathi eyomile ehlanzekile, egayiwe futhi egayiwe e-silica endaweni yokushisa engu-600-800 ° C, bese uyigaya ibe yimpushana. Lo mkhiqizo unosayizi wezinhlayiyana ezinhle kakhulu futhi ulungele ukuhlungwa okunembayo. Ivame ukusetshenziswa ngokuhambisana nezinye izinsiza zokuhlunga. Imikhiqizo eyomile ngokuvamile iphuzi ngokukhanyayo, kodwa futhi inobisi olumhlophe kanye nokumpunga okukhanyayo.

②Umkhiqizo one-calcined

Izinto zokusetshenziswa ze-diatomaceous ezihlanziwe, zomisiwe, nezichotshoziwe zifakwa kuhhavini ojikelezayo, zibalwe ezingeni lokushisa elingu-800-1200 ° C, bese zichotshozwa futhi zifakwe amagremu ukuze kutholwe umkhiqizo obaliwe. Uma kuqhathaniswa nemikhiqizo eyomile, imikhiqizo ye-calcined inokuvunyelwa okungaphezu kokuphindwe kathathu. Imikhiqizo eyenziwe nge-calcined ngokuvamile ibomvu ngokukhanyayo ngombala.

③Flux imikhiqizo calcined

Ngemuva kokuhlanzwa, ukomiswa, nokuchotshozwa, i-diatomaceous earth material eluhlaza yengezwa ngenani elincane lezinto eziguquguqukayo ezifana ne-sodium carbonate ne-sodium chloride, futhi i-calcined ekushiseni kwe-900-1200 ° C. Ngemva kokuchotshozwa nokulinganisa usayizi wezinhlayiyana, i umkhiqizo we-flux calcined uyatholakala. Ukungena komkhiqizo we-flux calcined kuye kwanda kakhulu, izikhathi ezingaphezu kwezingu-20 zomkhiqizo owomile. Imikhiqizo ebaliwe ene-flux ngokuvamile imhlophe ngombala, futhi uma okuqukethwe kwe-Fe2O3 kuphezulu noma umthamo we-flux uphansi, ubonakala ebomvana ngokukhanyayo.
