1, izinga lokushisa eliphezulu ukumelana indwangu 360 degrees Celsius ngaphansi lokushisa ultra-high ayishi, akusho ukuguga;Izindwangu ze-flame retardant zingashisa ngaphansi kwelangabi lokushisa eliphezulu.
2, indwangu retardant ilangabi ngemva komthombo umlilo ushiya ilangabi lingacisha ngokwalo;Indwangu yokumelana nokushisa okuphezulu ngeke izicime ngemva kokuba umthombo welangabi ushiya ilangabi.
I-3, indwangu evimbela ilangabi yenziwe ngekotini, i-polyester nezinye izinto zokusetshenziswa;Indwangu ekwazi ukumelana nokushisa okuphezulu yenziwe nge-fiber yengilazi engenisiwe ephezulu.
I-4, indwangu ekwazi ukumelana nokushisa okuphezulu ingamelana nokugqwala cishe kwazo zonke izinto zemithi, ezimweni eziqinile ze-asidi ne-alkali azigugi kanye nokuguqulwa;Indwangu ye-flame retardant ayinawo umsebenzi onjalo.
I-refractory yokushisa ukushisa ibhekisela ku-porosity ephezulu,Insulating Indwanguukuminyana kwevolumu ephansi, ukuhanjiswa kokushisa okuphansi kwe-refractory.I-refractory yokushisa ukushisa yaziwa nangokuthi i-light refractories.Kuhlanganisa imikhiqizo evimbela ukushisa, i-refractory fiber kanye nemikhiqizo ye-refractory fiber.Insulating Indwangu
I-refractory yokushisa ukushisa ibonakala nge-porosity ephezulu, ngokuvamile i-40% ~ 85%;Ukuminyana kwevolumu ephansi, ngokuvamile ngaphansi kuka-1.5g/cm3;I-thermal conductivity ephansi, ngokuvamile ingaphansi kuka-1.0W(m· K).Isetshenziswa njengezinto zokushisa ezishisayo zeziko lezimboni, inganciphisa ukulahlekelwa ukushisa kwesithando somlilo, yonge amandla, futhi inganciphisa isisindo semishini eshisayo.I-thermal insulation refractory amandla emishini, ukumelana nokugqoka kanye nokumelana nokuguguleka kwe-slag kubi, akufanele kusetshenziswe esakhiweni esithwala isithando somlilo kanye nokuxhumana okuqondile ne-slag, ukushaja, insimbi encibilikisiwe nezinye izingxenye.
Umkhiqizo we-refractory ovikela ukushisaInsulating Indwangu
Imikhiqizo ye-refractory yokushisa ukushisa ibhekisela emikhiqizweni ephikisayo ene-porosity engekho ngaphansi kwama-45%.Kunezinhlobo eziningi zemikhiqizo ye-thermal insulation refractory.Izindlela eziyinhloko zokuhlukanisa zimi kanje:
(1) Ngokusho kwezinga lokushisa lesevisi lihlukaniswe laba i-refractory yokushisa ephansi (izinga lokushisa lensizakalo lingu-600 ~ 900 ° C), i-refractory yokushisa okuphakathi nendawo (izinga lokushisa lesevisi liyi-900 ~ 1200 ° C) kanye ne-refractory yokushisa ephezulu (izinga lokushisa lesevisi likhudlwana ngaphezu kuka-1200 ° C).
(2) Ngokusho komthamo wevolumu ihlukaniswe ngama-refractories okukhanya ajwayelekile (ukuminyana kwevolumu ka-0.4 ~ 1.0g/cm3) kanye ne-ultra-low light refractories (ukuminyana kwevolumu ngaphansi kuka-0.4g/cm3).
(3) Ngokusho kwempahla eluhlaza ihlukaniswe ngobumba, i-aluminium ephezulu, i-silicon kanye ne-magnesium heat insulation refractory materials.
(4) Ngokwendlela yokukhiqiza, ihlukaniswe yaba indlela yokwengeza ukutubeka, indlela yegwebu, indlela yamakhemikhali kanye nendlela yempahla enezimbotshana nezinye izinto eziphikisayo ezishisayo.
(5) ngokusho ukuma kwemikhiqizo ihlukaniswe yaba ezimise imikhiqizo ukushisa ukwahlukanisa refractory kanye amorphous ukushisa ukwahlukanisa imikhiqizo refractory.
Imikhiqizo ye-thermal insulation refractory kanye nemikhiqizo ye-refractory eminyene ihlukile, izindlela eziyinhloko yindlela yokwengeza ukukhathala, indlela yegwebu, indlela yamakhemikhali kanye nendlela ye-porous material:
