Kungani okuqukethwe okuphansi kokungcola kunquma ukusebenza kwangempela kwesitini sokushisa esishisayo se-mullite?

Ezitovini ezishisayo, izitini zokuvikela zisebenza njalo1200–1400°C (2192–2552°F)ngenkathi ubhekene namagesi ashisayo anesivinini esikhulu, ukujikeleza kokushisa okuphindaphindiwe, ukuguguleka kothuli, kanye nokunciphisa umoya ngezikhathi ezithile okuqukethe i-CO ne-H₂. Lena indawo evamile yokucindezeleka okuhlanganisiwe okushisa okuphezulu. Izitini zokuvimbela ezivamile ezinokuqukethwe okuphezulu kokungcola zivame ukubhekana nalokhu:

• Ukuthambisa nokuguquguquka ngenxa yokwakheka kwesigaba esinjengengilazi ngokweqile emazingeni okushisa aphezulu

• Ukuwohloka kwe-Mullite okuholela esakhiweni esincane esibuthakathaka nesibuthakathaka

• Ukungcola okusekelwe ku-iron kuyancishiswa futhi kuba yimpuphu, okubangela ukulahlekelwa amandla

Zonke lezi zindlela zokwehluleka zikhomba imbangela eyodwa ebalulekile:ukungcola okweqile.

Isitini sokufakelwa i-mullite se-CCEWOOL® sithuthukisa ukuzinza kwezitini isikhathi eside ngaphansi kwezimo ezimbi kakhulu ngokulawula ngokuqinile ubumsulwa bezinto zokusetshenziswa kanye nokuqinisa isakhiwo se-crystal phase, kufinyelela amazinga okungcola angaphansi kakhulu kwesilinganiso semboni.

I-CCEWOOL® ithuthukisa kanjani ukuzinza kwendwangu yesitofu esishisayo ngokunciphisa okuqukethwe ukungcola?

Ukulawulwa Kokuhlanzeka Kwezinto Ezingavuthiwe: Uhlelo Lokungcola Okuphansi Olwakha Uhlaka Oluzinzile Kakhulu Lwezinga Lokushisa Eliphezulu

Isitini sokuvikela i-mullite se-CCEWOOL® sisebenzisa izinto zokusetshenziswa ezihlanzekile kakhulu ezivela emigodini yaso yamaminerali futhi sinciphisa ngokuqinile ukungcola okuncibilika kancane njengokuncibilikaI-Fe₂O₃, i-K₂O, kanye ne-Na₂OUkuhlolwa kwangaphambili okuzenzakalelayo kususa izinhlayiya zensimbi nothuli lobumba, okuqinisekisa ukuncibilika okuhlanzekile kanye nesigaba sekristalu esizinzile ngemva kokusha.

Uhlelo olungcolile oluphansi luthuthukisa ngqo ukusebenza kwezinga lokushisa eliphezulu:

• Ukwakheka kwesigaba esinjengengilazi okuncishisiwe– izitini zihlala ziqinile ku-1200–1400°C ngaphandle kokuthamba noma ukubhidlika ngaphambi kwesikhathi

• Ukunciphisa ukusabela kwekristalu okungathandeki– uhlaka lwe-mullite lugcina ukuqhubeka okuphezulu, futhi izindonga zembobo azigobeki noma azixhumani

• Ukuqina kwembobo yesikhathi eside- izindonga zembobo ziyamelana nokushwabana noma ukuqhekeka ngesikhathi sokujikeleza kokushisa, okugcina ukuhanjiswa kokushisa kuzinzile

Ngale ndlela yokuhlanzeka okuphezulu kanye nokungcola okuncane, izitini zokufakelwa i-mullite ze-CCEWOOL® zibonisa ukuqina okuphezulu kanye nokuqina kwesakhiwo ezimweni zokusebenza ezinzima zezitofu ezishisayo.

Ukudubula Ngokunembile: Ukunciphisa Imiphumela Yokungcola Ngokusebenzisa Ukuhlanza Okulawulwayo

Izitini zokuvikela i-mullite ze-CCEWOOL® ziyashiswaIsitofu somhubhe esisebenza ngokuzenzakalelayo samamitha angu-88, okuqinisekisa insimu yokushisa eqinile nefanayo. Lokhu kuvimbela ukushaqeka noma ukushaqeka ngokweqile futhi kuvumela ukungcola okuncibilika kancane ukuthi kusabela ngokugcwele noma kuguquke ngesikhathi senqubo yokushaqeka engu-1200–1350°C, okuholela esakhiweni se-mullite esiqinile nesiqinile.

Ngokusekelwe kulolu hlelo olungenakungcola okuphansi, izitini zokufakelwa i-mullite ze-CCEWOOL® zinikeza izinzuzo ezibalulekile zokusebenza:

• Ama-pores ambalwa futhi akukho ukuthamba okushisa okuphezulu, ukuqinisekisa ukuqina kwesimo

• I-skeleton ye-mullite eqhubekayo, okuthuthukisa ukumelana nokushaqeka kokushisa

• Izindonga zembobo ezinganciphi noma ezidilikayo, ukugcina ukujiya kanye nobuqotho bomshini

Ngenxa yalokho, izitini zithola ukuncibilika okuphansi okuqondile, amandla aphezulu okucindezela, kanye nokuqina okuphezulu kokushaqeka kokushisa, okuvimbela ukuqhuma noma ukuqhekeka ngesikhathi senkonzo yesikhathi eside futhi kuhlinzeka ngesakhiwo sendwangu esithembeke kakhulu.

Ngokuqukethwe okungcolile okuphansi kakhulu, izitini zokuvikela ze-CCEWOOL® mullite zigcina ukuqina kwesakhiwo ngaphansi kwamazinga okushisa aphezulu, ukushaqeka kokushisa, kanye nokunciphisa umoya. Zimelana nokuthamba kanye nokuba yimpuphu ngenkathi zigcina ukusebenza kokushisa kwesikhathi eside. YingakhoIsitini sokuvikela i-mullite se-CCEWOOL®inikeza ukuthembeka okuphezulu kanye nokuphila isikhathi eside kwesevisi ezisetshenziswayo zesitofu esishisayo.
