Uhlobo lwentsimbi yeBell

Ubume:
Uhlobo lweentsimbi zeBell zisetyenziselwa ikakhulu ukuqaqanjelwa okunyangayo kunye nonyango lobushushu, ke zizinto ezinobushushu ezahluka-hlukeneyo. Iqondo lobushushu lihlala phakathi kwe-650 kunye ne-1100 ℃ ubukhulu becala, kwaye litshintsha ngexesha elichaziweyo kwinkqubo yokufudumeza. Ngokusekwe ekulayisheni uhlobo lweentsimbi zentsimbi, zimbini iintlobo: isithando somlilo esenziwe ngesikwere kunye nesithando sentsimbi esingqukuva. Imithombo yobushushu bentsimbi yohlobo lwentsimbi ubukhulu becala yigesi, ilandelwa ngumbane kunye neoyile elula. Ngokubanzi, iifanitshala zohlobo lweentsimbi zinamalungu amathathu: isiciko sangaphandle, isiciko sangaphakathi kunye nesitovu. Isixhobo esivuthayo sihlala sibekwe kwisiciko sangaphandle esigqunywe ngumoya oshushu, ngelixa izixhobo zomsebenzi zibekwe kwikhava yangaphakathi yokufudumeza nokupholisa.

Uhlobo lweentsimbi zeBell zinokuqina komoya okuhle, ukulahleka kobushushu obuphantsi, kunye nokusebenza okuphezulu kobushushu. Ngapha koko, akukho mfuneko yokuba ucango lomlilo okanye indlela yokuphakamisa kunye nezinye iindlela zothumelo loomatshini, ke zona zigcina iindleko kwaye zisetyenziswa kakhulu kwiziko lokunyanga ubushushu ngezinto zokusebenza.
Ezimbini zeemfuno ezibaluleke kakhulu kwizinto zokufakelwa komlilo zizinto ezinobunzima kunye nokusebenza kwamandla kwezikhuselo zokufudumeza.

Iingxaki eziqhelekileyo kwi-Refracto yesiko elulaizitena zery okanye ukukhanya okulula okuhanjiswayo stUkonakala kubandakanya:

1. Izinto ezingaxutywanga ezinomxhuzulane othile (ubukhulu becala izitena ezikhanyisayo ezinobunzima obukhulu zinomxhuzulane othile we-600KG / m3 okanye nangaphezulu; i-lightweight castable ine-1000 KG / m3 okanye nangaphezulu) ifuna umthwalo omkhulu kubume bentsimbi beqweqwe lomlilo. Ukusetyenziswa kwesakhiwo sensimbi kunye notyalo-mali kulwakhiwo lweziko.

2. Isigqubuthelo esingaphandle esikhulu sichaphazela ukuphakamisa amandla kunye nendawo yomgangatho woomasifundisane bokuvelisa.

3. Iziko lohlobo lwentsimbi lisebenza kumaqondo obushushu ahlukeneyo, kwaye izitena ezikhanyayo ezikhanyayo okanye ukukhanya okukhanyayo kunamandla amakhulu obushushu, ukuhambisa okuphezulu kobushushu, kunye nokusetyenziswa kwamandla amakhulu.

Nangona kunjalo, iimveliso ze-fiber ezinqabileyo ze-CCEWOOL zine-low conductivity ye-thermal, ukugcinwa kobushushu obuphantsi, kunye nevolumu esezantsi yevolumu, ezizezona zizathu ziphambili zokufaka kwabo ngokubanzi kwizembozo zokufudumeza. Iimpawu zezi zilandelayo:

1. Uluhlu olubanzi lobushushu bokusebenza kunye neefom zesicelo ezahlukeneyo
Ngokuphuhliswa kwemveliso yefayibha yodongwe kunye netekhnoloji yeCCEWOOL, iimveliso zefiber zeceramic zifezekise ukusebenza ngokulandelelana kunye nokusebenza. Ngokwamaqondo obushushu, iimveliso zinokuhlangabezana neemfuno zobushushu ezahlukeneyo ukusuka kwi-600 ukuya kwi-1500 ℃. Ngokwe-morphology, iimveliso ziye zaphuhlisa ngokuthe ngcembe iintlobo zokuqhubekekiswa okwesibini okanye iimveliso zokwenza nzulu ezivela kumqhaphu wesiko, iingubo, ukuziva iimveliso kwiimodyuli zefayibha, iibhodi, iindawo ezimile ngokukodwa, iphepha, amalaphu efayibha njalo njalo. Banokukhawulelana ngokupheleleyo neemfuno zeshishini lokwenza imveliso yefayibha yodongwe kwimizi mveliso eyahlukeneyo.
Ubuninzi bevolumu encinci:
Ubuninzi bevoluyum yeemveliso zefayibha yodongwe ngokubanzi yi-96 ~ 160kg / m3, emalunga ne-1/3 yezitena ezingasindiyo kunye ne-1/5 yesikhombisi esikhanyayo esincinci. Kwisithando somlilo esandula kuyilwa, ukusetyenziswa kweemveliso zefayibha yodongwe akunakusindisa kuphela isinyithi, kodwa kukwenza ukulayishwa / ukothula kunye nokuhambisa ngokulula, kuqhubela phambili inkqubela phambili kwitekhnoloji yesithando somlilo.
3.ubushushu obuncinci kunye nokugcina ubushushu:
Xa kuthelekiswa nezitena ezitsalayo kunye nezitena zokwambathisa, umthamo weemveliso zefayibha yeceramic uphantsi kakhulu, malunga ne-1 / 14-1 / 13 yezitena ezitsalayo kunye ne-1 / 7-1 / 6 yezitena zokugquma. Kwiziko leentsimbi elisebenza rhoqo, isixa esikhulu sokusetyenziswa kwepetroli esinxulumene nemveliso sinokugcinwa.
4. Ulwakhiwo olulula, ixesha elifutshane
Njengoko iingubo ze-ceramic fiber kunye neemodyuli zine-elasticity egqwesileyo, isixa soxinzelelo sinokuqikelelwa, kwaye akukho mfuneko yokushiya amalungu ngokudibanisa ngexesha lokwakha. Ngenxa yoko, ulwakhiwo lulula kwaye lulula, olunokugqitywa ngabasebenzi abanesakhono esiqhelekileyo.
5.Ukusebenza ngaphandle kwe-oveni
Ngokwamkela i-fiber egcweleyo, iifanishi zinokufudumeza ngokukhawuleza kwinkqubo yobushushu ukuba azithintelwanga ngamanye amacandelo esinyithi, okuphucula kakhulu ukusetyenziswa okusebenzayo kwamaziko asemashishini kunye nokunciphisa ukusetyenziswa okungafunekiyo okunxulumene nemveliso.
6. Ukuqhuba kwe-thermal ephantsi kakhulu
Ifayibha yodongwe yindibaniselwano yemicu enobubanzi be-3-5um, ke ine-conductivity eshushu kakhulu esezantsi. Umzekelo, xa ingubo ye-aluminium ephezulu ene-128kg / m3 ifikelela kwi-1000 ℃ kwindawo eshushu, umlinganiso wayo wokuhambisa ubushushu yi-0.22 kuphela (W / MK).
7.Ukuzinza okuhle kwemichiza kunye nokumelana nokhukuliseko lomoya:
Ifayibha yeCeramic inokuchithwa kuphela kwi-phosphoric acid, i-hydrofluoric acid, kunye ne-alkali eshushu, kwaye izinzile kweminye imithombo yeendaba. Ukongeza, iimodyuli ze-ceramic fiber zenziwa ngokuqhubeka kusongelwa iingubo zefayibha zeceramic kwinqanaba elithile lokunciphisa. Emva kokuphathwa komphezulu, ukumelana nokhukuliseko lomoya kungafikelela kwi-30m / s.
