Ingubo yeCeramic Fiber: Iipropati zePremium kunye neeNkcukacha eziQhelekileyo zoVavanyo lweMizi-mveliso

Kwicandelo lokufakelwa kwe-insulation kwimizi-mveliso enobushushu obuphezulu,ingubo yefayibha yeseramikhiIbonakala njengesisombululo esingabizi kakhulu nesisebenza kakuhle, esisetyenziswa kakhulu kwi-metallurgy, ii-petrochemicals, ukuvelisa umbane, kunye namanye amashishini. Yenziwe ngezinto ze-alumina-silica ezicocekileyo kakhulu ngeenkqubo zokujikeleza okanye ukuvuthela kwaye ifakelwe inaliti ngoomatshini ngaphandle kwezinto zokubopha, idibanisa ukumelana okuhle kobushushu, ukuguquguquka, kunye nokuqina, okwenza ukuba ibe yinto ebalulekileyo kwizisombululo zanamhlanje zolawulo lobushushu.

Iimpawu ezibalaseleyo zengubo yefayibha yeseramikhi zezona zibalulekileyo ekuthandweni kwayo ngokubanzi. Okokuqala, inesimo sokumelana nobushushu obuphezulu kakhulu, kunye namaqondo obushushu aqala kwi-1100℃ ukuya kwi-1600℃ (2012℉ ukuya kwi-2912℉) kuxhomekeke kudidi, kunye namaqondo obushushu asebenzayo aqhubekayo ukuya kuthi ga kwi-1350℃ kwiindidi eziphezulu, okuqinisekisa ukusebenza okuzinzileyo nakwiindawo ezishushu kakhulu. Ukuqhuba kwayo ubushushu obuphantsi kakhulu (okungaphantsi kwe-0.09 W/MK kwi-400℃) kunciphisa ukulahleka kobushushu, kuphucula ukusebenza kakuhle kwamandla kunye nokunciphisa ukusetyenziswa kwepetroli ngama-20-40% kwizicelo zoshishino.

Ilula kwaye iguquguquka, ingubo ilula ngama-70% kunezixhobo zemveli zokurhawuzelela, nto leyo eyenza ukuba ukufakwa kube lula—nokuba kwiimo ezinzima ezifana neendonga zesithando somlilo, iipayipi, kunye namalungu okwandisa. Inamandla okumelana nobushushu obuphezulu, kunye nokuncipha okuthe tyaba okungaphantsi kwe-3% kumaqondo obushushu aphezulu okusebenza, ithintela umonakalo obangelwa kukutshintshatshintsha kobushushu ngokukhawuleza. Ukongeza, ayinazo iibhanti, ayitshi, kwaye izinzile kakuhle kwiikhemikhali, imelana nezona zinto zibangela ukubola (ngaphandle kwe-alkalis enamandla kunye ne-hydrofluoric acid) kwaye iqinisekisa ukuba akukho gesi iphumayo ngexesha lokusetyenziswa, nto leyo ephucula ukhuseleko kunye nobuhlobo nokusingqongileyo. Ikwabonelela ngemisebenzi yokufunxa isandi kunye nokunciphisa ingxolo, iphucula ngakumbi imeko yokusebenza.

Ukuze kuhlangatyezwane neemfuno ezahlukeneyo zoshishino, iblanketi yefayibha yeseramikhi iza ngokweemfuno ezisemgangathweni kunye neendlela eziguquguqukayo zokwenza ngokwezifiso. Ngokuphathelele uxinano, iindlela eziqhelekileyo ziyi-96, 128, kunye ne-160 kg/m³ (6-10 lb/ft³), kunye neendidi ezithile ezifumaneka kwi-64 kg/m³ kwiimfuno ezilula, ukulinganisela ukusebenza kwe-insulation kunye nokusebenza kakuhle kobunzima. Ubukhulu buqala kwi-6mm ukuya kwi-50mm (0.25-2 intshi), apho iingubo ezincinci ze-6-10mm zilungele iindawo ezixineneyo, i-20-25mm nganye ilungele ukusebenza kunye nomthamo, kwaye i-50mm nganye ibonelela ngokugcinwa kobushushu okuphezulu kwiimeko zobushushu obuphezulu kakhulu.

Ngokwemilinganiselo, imiqulu eqhelekileyo inobude obuyi-7200/3600mm, ububanzi obuyi-610/1220mm, kwaye ingenziwa ngokwezifiso ukuya kuthi ga kwi-16000mm kunye nobubanzi obuyi-1830mm ngokweemfuno zeprojekthi. Ngokwekhemikhali, izinto eziphambili yi-alumina (Al₂O₃) kunye ne-silica (SiO₂), kunye nomxholo opheleleyo we-96-99% kwiindidi ezininzi; iindidi ezine-zirconium zongeza i-5-17% ZrO₂ ukuphucula uzinzo lobushushu obuphezulu, kunye ne-Al₂O₃+SiO₂+ZrO₂ efikelela kwi-99%. Amandla okutsalwa yi-0.04-0.12 MPa (ubuninzi obuyi-128kg/m³), ukuqinisekisa ukuthembeka kwesakhiwo ngexesha lokufakwa nokusetyenziswa.

Nokuba zeze-furnace linings, i-boiler insulation, i-pipe protection, okanye i-fire seals, i-ceramic fiber blanket inika ukusebenza okuthembekileyo, ukonga amandla, kunye nobomi benkonzo ende. Iimpawu zayo eziguquguqukayo kunye neenkcukacha ezinokwenziwa ngokwezifiso zenza kube lukhetho lokuqala lwe-insulation yobushushu obuphezulu kumashishini onke. Khetha i-ceramic fiber blanket yethu ukuze uphucule inkqubo yakho yolawulo lobushushu, unciphise iindleko zokusebenza, kwaye ufezekise uphuhliso oluzinzileyo.
