Ekuphuhlisweni kweenkqubo zoshishino ezinobushushu obuphezulu, izixhobo zokwambathisa ziye zatshintsha kakhulu—ukusuka ekufakweni kwe-insulation yoboya belitye (ukufakeni i-insulation yoboya belitye) ukuya kwi-fiber ye-ceramic engabonakaliyo. Ekuqaleni, oku kunokubonakala ngathi kukuphuculwa kwemveliso okulula. Nangona kunjalo, ngokwembono yobunjineli bezinto, olu tshintsho lubonisa ukuqhubela phambili okuqhubekayo kwiinkqubo zezinto eziluhlaza, ubuchwepheshe bokuvelisa, kunye nobuchule bokulawula izakhiwo ezincinci.
Olu tshintsho lwenze ukuba izixhobo zokukhusela ubushushu obuphezulu zikwazi ukuhamba ukusuka kwimida yobushushu obungamakhulu aliqela degrees Celsius ukuya ngaphezulu kwe-1000 °C, zixhasa uphuhliso lwee-oven zoshishino, izixhobo zonyango lobushushu, kunye neenkqubo ze-metallurgical ezisebenza kumaqondo obushushu aphezulu kunye nokusebenza kakuhle kobushushu okuphuculweyo.
Uphuhliso lweeNkqubo zezinto eziluhlaza: Ukusuka kwiiminerali zendalo ukuya kwii-okside ezilungisiweyo
Ubushushu boboya belitye be-CCEWOOL®, edla ngokubizwa ngokuba yi-rock wool insulation, iyinxalenye yosapho lweemveliso zefayibha yezimbiwa. Izinto zayo eziphambili zokwenza izinto ziquka iinkqubo zeminerali zendalo ezifana ne-basalt, i-limestone, kunye ne-blast furnace slag. Ngexesha lokuveliswa, ezi minerali ziyanyibilika zize ziguqulwe zibe zizakhiwo ze-fibrous ngokusebenzisa iinkqubo zokujikeleza okanye zokuvuthela ngesantya esiphezulu.
Kwindlela eqhelekileyo yokwenza izinto, iimveliso zoboya belitye ziqulathe ngaphezu kwama-70% ezinto zelitye lendalo, kwaye inxalenye eseleyo isuka kwi-slag kunye nezinye izongezo zezimbiwa. Le nkqubo yezinto eziluhlaza ineempawu ezimbini ezisisiseko:
- Ulwakhiwo lweekhemikhali ezintsonkothileyo ezinamazinga aphezulu okungcola
- Isakhiwo seeminerali esilawulwa ziinkqubo ze-calcium-magnesium silicate
Ngenxa yoko, nangona ubushushu boboya belitye bunika ukumelana okuhle nomlilo kunye nokusebenza kakuhle kobushushu, ulwakhiwo lwalo luyathamba kancinci kancinci kumaqondo obushushu aphezulu. Kwiimeko ezininzi zoshishino, ubushushu obuzinzileyo bokusebenza bexesha elide bobushushu boboya belitye buhlala buphakathi kwe-700–850 °C.
Njengoko iinkqubo zoshishino ziqhubeka zifuna amaqondo obushushu aphezulu okusebenza, le nkqubo yezimbiwa yendalo kancinci kancinci ayanelanga kwiindawo ezifuna ubushushu obuninzi.
Intshayelelo kaIfayibha yeseramikhi enganyangekiyo ye-CCEWOOL®uphawule utshintsho olukhulu kwiinkqubo zezinto zokwambathisa ezisetyenziswa kwizinto zokwambathisa. Ngokungafaniyo nokwambathisa uboya belitye, iimveliso zefayibha zeseramikhi ezinganyangekiyo zihlala zenziwe nge-alumina ecocekileyo kakhulu (Al₂O₃) kunye ne-silica (SiO₂).
Le nkqubo ye-oxide eyilwe ngobunjineli inamanqaku aphezulu okunyibilika kunye nozinzo oluphezulu lweekhemikhali. Ngenxa yoko, izixhobo zokukhusela iifayibha zeseramikhi ezinganyangekiyo zinokusebenza ngokuthembekileyo kwiindawo ezingaphaya kwe-1000 °C kwaye zide zifikelele kwi-1400 °C, kuxhomekeke kubushushu bohlobo lwemveliso.
Ngokwembono yobunjineli bezinto, olu tshintsho lubonisa utshintsho oluvela kwiinkqubo zeminerali zendalo ukuya kwiinkqubo zezinto ezilungisiweyo ezineekhemikhali ezilawulwa ngokuchanekileyo.
Inkqubela phambili kwiTekhnoloji yoKwenziwa kweMveliso: Ukusuka kwiMineral Fiberization ukuya kwiTekhnoloji yeMelt Fiber eNzulu yoBushushu
Utshintsho kwiinkqubo zezinto eziluhlaza lukwakhokelele ekuphuculeni ubuchwepheshe bokuvelisa.
Inkqubo yokuvelisa i-insulation yoboya belitye sele ikhulile. Amanyathelo aphambili adla ngokuquka:
- Izinto ezinyibilikisa amatye kunye nezinto ezitshixwayo kubushushu obumalunga ne-1500–1600 °C
- Ukuguqula izinto ezinyibilikisiweyo zibe yimicu ngokusebenzisa iidiski ezijikelezayo ngesantya esiphezulu okanye ukuvuthela ngomoya
- Ukuphola nokuqokelela iifayibha ukuze zenze iimathi zokukhusela ezifana noboya
Nangona le nkqubo ivumela ukuveliswa okukhulu, iifayibha eziphumayo zihlala ziqinile ngobubanzi, kwaye ukufana kwesakhiwo sefayibha kunokulinganiselwa.
Ngokwahlukileyo koko, ukuveliswa kwefayibha yeseramikhi enganyangekiyo kufuna amaqondo obushushu aphezulu kakhulu kunye nezixhobo zokucubungula eziphucukileyo.
Kwimveliso yemizi-mveliso, izinto eziluhlaza ze-alumina kunye ne-silica ziyanyibilika kumaqondo obushushu asondela kwi-2000 °C, emva koko izinto ezinyibilikisiweyo ziguqulwa zibe yimicu ngokusebenzisa iinkqubo zokujikeleza okanye zokuvuthela ngesantya esiphezulu.
Le ndlela yokuvelisa ivumela ukuveliswa kweefayibha nge:
- Iidayamitha ezincinci zefayibha
- Ubumsulwa obuphezulu bezinto ezibonakalayo
- Iinethiwekhi zefayibha ezifanayo ngakumbi
Ezi mpawu zikhokelela kwiingenelo ezininzi zokusebenza eziphambili kwizixhobo zefayibha zeseramikhi ezingafunekiyo, kuquka:
- Ukuqhuba okuphantsi kobushushu
- Ukuguquguquka okukhulu
- Ukumelana nokuxhathisa okushushu okuphezulu
Ezi mpawu zibalulekile kwiinkqubo zanamhlanje zokufakelwa kwee-oven ezisebenza phantsi kweemeko zobushushu obuphezulu.
Ukwanda koBuchule boBushushu: Iinkqubo zezinto ezisetyenzisiweyo zichaza imida yoBushushu
Amandla obushushu ezinto zokukhusela axhomekeke kakhulu kulwakhiwo lweekhemikhali kunye nokuzinza kwesakhiwo.
Ulwakhiwo lwefayibha yokufakelwa koboya belitye lusekelwe kwinkqubo yeglasi yesilika entsonkothileyo. Kumaqondo obushushu aphezulu, olu lwakhiwo luyathamba kancinci kancinci kwaye lutshintshe ulwakhiwo. Ngenxa yoko, ukufakwa koboya belitye kusetyenziswa kakhulu ekwakheni iinkqubo zokukhusela umlilo kunye nokusetyenziswa kokufakelwa kobushushu obuphakathi.
Umzekelo, kwizakhiwo zokukhusela umlilo, ubushushu boboya belitye bunokumelana nomlilo ongaphezulu kwe-1000 °C ngaphandle kokutsha, nto leyo eyenza ukuba isetyenziswe kakhulu kwiinkqubo zokukhusela umlilo ezingasebenziyo.
Nangona kunjalo, kwiindawo zoshishino ezifuna ukusebenza ixesha elide kubushushu obuphezulu, inkqubo yezinto zoboya belitye inemida yayo.
Ngokwahlukileyo koko, izinto zefayibha yeseramikhi ezinganyangekiyo zisekelwe kwinkqubo ye-alumina-silica oxide enyibilikisa kakhulu. Ngokusebenzisa ngcono ubumsulwa bezinto eziluhlaza kunye nolawulo lwesakhiwo, inkqubo yokwenza ikristale kumaqondo obushushu aphezulu inokulibaziseka ngempumelelo, okuvumela ulwakhiwo lwefayibha ukuba luhlale luzinzile phantsi kweemeko zobushushu obuqatha.
Ngenxa yoko, izixhobo zokwambathisa ifayibha ye-ceramic enganyangekiyo zihlala zineqondo lobushushu eliqala kwi-1100 °C ukuya kwi-1430 °C, nto leyo evumela ukuba zisetyenziswe kakhulu kwizicelo ezifana nezi:
- Izitofu zokufudumeza ezenziwe ngesinyithi
- Izixhobo zonyango lobushushu
- Iziko zokuqhekeka kwe-Petrochemical
- Ii-oven zoshishino ezishushu kakhulu
Kwezi nkqubo, ukufakelwa kwefayibha yeseramikhi enganyangekiyo akunciphisi nje kuphela ubunzima be-furnace kodwa kunciphisa kakhulu ukulahleka kobushushu.
Ingcamango Yokwenene Ebangela Ukuguquka Kwezinto Zokukhusela Ezinobushushu Obuphezulu
Utshintsho oluvelaUbushushu boboya belitye be-CCEWOOL® (ubushushu boboya belitye) ukuyaIfayibha yeseramikhi enganyangekiyo ye-CCEWOOL®Asikuko nje ukutshintshwa kwemveliso enye ngomnye. Kunoko, kubonisa ukuqhubela phambili okuqhubekayo kobunjineli bezinto ezisebenzisa amaqondo obushushu aphezulu.
Ngokusisiseko, olu tshintsho luqhutywa zizinto ezintathu eziphambili: ukuguquka kweenkqubo zezinto eziluhlaza ukusuka kwizinto zendalo ezidityanisiweyo ukuya kwii-oxides ezilungisiweyo ezicocekileyo kakhulu, ukuqhubela phambili kwetekhnoloji yokuvelisa ukusuka kwi-fiberization yeminerali eqhelekileyo ukuya kwimveliso ye-melt fiber enobushushu obuphezulu, kunye nolawulo oluphuculweyo kwi-microstructure yezinto ngokusebenzisa ukwakheka kunye nokwenza ngcono inkqubo.
Xa zizonke, olu phuculo lwetekhnoloji luye lwenza ukuba izixhobo zokukhusela ubushushu zandise amandla azo obushushu ukusuka kumakhulu aliqela eedigri Celsius ukuya ngaphezulu kwe-1000 °C. Le nkqubela ixhase ukusebenza kweenkqubo zanamhlanje ze-metallurgical, ubushushu, kunye ne-petrochemical ezifuna ukusebenza okuphezulu kobushushu kunye nokusebenza kakuhle kwamandla.
Ekugqibeleni, uphuhliso lwezinto zokukhusela ezisebenzisa ubushushu obuphezulu alukokutshintsha nje uhlobo lwemveliso, kodwa lusiphumo senkqubela phambili eqhubekayo ekucocekeni kwezinto eziluhlaza, iteknoloji yokuvelisa, kunye nobunjineli bezakhiwo ezincinci.
