Isitini Sokushisisa Ubumba Esilula uhlobo lwezinto zokushisa ezisezingeni eliphezulu ezingasetshenziswa kuzo zonke izinhlobo zokusetshenziswa kwesitofu sezimboni ezinezakhiwo ezinhle kakhulu zamandla aphezulu, ukuminyana okulinganayo, ukuhanjiswa kokushisa okuphansi kanye nokungcola okuphansi. Isitini sokushisa sobumba sikhiqizwa ngezinto zokusetshenziswa zobumba oluqinile ngaphansi kokushisa okuphezulu ngokusho kobuchwepheshe bethu bokukhiqiza obuthuthukisiwe. Ibhulokhi lokushisa lobumba lingasetshenziswa esithandweni sokuncibilikisa, emishinini yokuhlanza, imishini yokushisa, imishini yokuvuselela, isithando segesi, umgodi wokucwilisa, isithando sokushisa, eminye imishini yokusebenza eshisayo yezimboni kanye negumbi lokusabela.

Incazelo Yezitini Zokufaka Ubumba Ezincane

Isitini Sokushisela Ubumba Esilula senziwe ngobumba lomlilo njengento eluhlaza kanye nobumba lwepulasitiki njenge-ejenti yokubopha bese kungezwa i-ejenti evuthayo noma ekhipha igwebu efanele ngokudubula. Ubumba lokuvikela luvimba ukuvuleka okubonakalayo kuphezulu cishe ngo-40 ~ 85% kanti ubukhulu bungaphansi kuka-1.5 g/cm3. Izitini zokuvikela umlilo zobumba zisetshenziswa kakhulu njengezinto zokuvikela kuhhavini wezimboni ukunciphisa ukulahlekelwa ukushisa kwehhavini, ukonga amandla kanye nokunciphisa ikhwalithi yemishini yokushisa.

Izakhiwo Zezitini Zokufaka Ubumba Ezilula Ezinesisindo Esilula

Amazinga aphansi ensimbi nokunye ukungcola,
Ukuqina okuphezulu,
Izimbobo eziphezulu, ukuminyana kwevolumu okuphansi,
Umphumela omuhle wokuvimbela ukushisa kanye nokonga amandla,
Ukuqina okuhle kokushaqeka kokushisa,
Ukumelana nokugqwala nokuguguleka.

Inqubo Yokukhiqiza Isitini Sokufaka Ubumba Esilula Esinesisindo Esilula

Izitini Zokushisela Ubumba Ezilula Zenziwe ngobumba olucwengekile kanye ne-binder, ngokufaka ukushisa okuphezulu. Amabhlogo okushisela ubumba ayizitini zokushisela ezingabizi kakhulu ezisebenza kahle kakhulu. Izinzuzo eziyinhloko zebhloko lokushisela ubumba ukushisela okuphezulu ngaphansi komthwalo, ama-coefficients okukhulisa umugqa ophansi, ukumelana okuhle nokushaqeka kokushisa kanye nekhono eliqinile lokumelana nokuguguleka. Enziwe ngezinto zobumba olucwengekile lomlilo zendawo ezisezingeni eliphezulu ngaphansi kokushisa okuphezulu ngokwezinga elihlala isikhathi eside likazwelonke, elinobukhulu obulinganayo, amandla aphezulu, ukuhanjiswa kokushisa okuphansi kanye nokungcola okuphansi.

Ukwakheka Kwezitini Zokufaka Ubumba Ezilula

Isitini somlilo sokufaka ubumba siwumkhiqizo oqinile one-Al2O3 engaba ngu-30~40%. Enziwe ngobumba oluthambile olungama-50% kanye ne-chamotte eqinile engama-50% ngokwesilinganiso esithile, kufanele ixutshwe futhi ishiswe ku-1300~1400 ℃ ekushiseni okuphezulu ngemva kokubumba nokomisa. Ukwakheka kwamaminerali okuyinhloko kwesitini sokufaka ubumba kuhlanganisa i-kaolinite (Al2O3·2SiO2·2H2O) kanye nokungcola okungu-6~7% (K, Na, Ca, Ti, Fe oxide).

Ukusetshenziswa Kwezitini Zokufaka Ubumba Ezilula

Ibhulokhi lokuvikela ubumba lisetshenziswa kakhulu ekufakeni ulwelwesi oluvikela izindawo ezishisayo noma izingqimba zokuvikela ukushisa ezisekela ezinye izinto ezivimbela ukushisa. Izingqimba ezivimbela ukushisa noma izinto ezivimbela ukushisa zezimboni, njengezitofu ze-ethylene pyrolysis, izitofu zamashubhu, izitofu zokulungisa ze-ammonia yokwenziwa, amajeneretha egesi kanye nezitofu ze-shullte zokushisa okuphezulu, njll.
