I-1, ilaphu elixhathisa ubushushu obuphezulu kwi-360 degrees Celsius phantsi kobushushu be-ultra-high ayitshisi, ayigugi;Amalaphu abuyisela amadangatye angatsha phantsi kobushushu obuphezulu bomlilo.
2, ilaphu elibuyisela idangatye emva kokuba umthombo womlilo ushiya idangatye linokucima ngokwalo;Ilaphu eliphezulu elichasayo lobushushu aliyi kuzicima emva kokuba umthombo womlilo ushiya ilangatye.
I-3, ilaphu elibuyisela idangatye lenziwe ngomqhaphu, ipolyester kunye nezinye izinto ezikrwada;Ilaphu elimelana nobushushu obuphezulu lenziwe ngefiber yeglasi ephuma kumazwe angaphandle ekumgangatho ophezulu.
I-4, ilaphu elixhathisa ubushushu obuphezulu linokumelana nokubola phantse zonke izinto zamayeza, kwiimeko ze-asidi eyomeleleyo kunye ne-alkali azigugi kunye nokuguqulwa;Ilaphu le-flame retardant alinamsebenzi onjalo.
Irefractory yokufakelwa kobushushu ibhekisa kwiporosity ephezulu,Ilaphu lokugqumaukuxinana komthamo ophantsi, ukuhanjiswa kwe-thermal ephantsi ye-refractory.I-refractory yokugquma ubushushu ikwabizwa ngokuba zii-refractories zokukhanya.Ibandakanya iimveliso zokunqanda ukugquma ubushushu, i-refractory fiber kunye neemveliso zefiber refractory.Ilaphu lokugquma
I-refractory yokushisa ubushushu ibonakala nge-porosity ephezulu, ngokubanzi i-40% ~ 85%;Ubuninzi bomthamo ophantsi, ngokubanzi ngaphantsi kwe-1.5g / cm3;I-thermal conductivity ephantsi, ngokubanzi ngaphantsi kwe-1.0W(m· K).Isetyenziswa njengesixhobo sokufakelwa kwe-thermal se-kiln ye-industrial, inokunciphisa ilahleko yobushushu kwiziko, yonga amandla, kwaye inokunciphisa ubunzima bezixhobo ezishushu.I-thermal insulation refractory amandla omatshini, ukuxhathisa ukunxiba kunye nokumelana nokukhukuliseka kwe-slag kubi, akufanele kusetyenziswe kwisakhiwo sokuthwala isithando somlilo kunye nokudibanisa ngokuthe ngqo kunye ne-slag, intlawulo, isinyithi esityhidiweyo kunye nezinye iindawo.
Ubushushu bemveliso refractoryIlaphu lokugquma
Iimveliso ze-refractory zokugquma ubushushu zibhekisela kwiimveliso ezichasayo ezine-porosity engekho ngaphantsi kwe-45%.Kukho iintlobo ezininzi zeemveliso zokunqanda ukugquma kwe-thermal.Iindlela zokuhlela eziphambili zezi zilandelayo:
1 ngaphezu kwe-1200 ° C).
(2) Ngokwe-volume density yahlulwe ibe yi-refractories yokukhanya ngokubanzi (ubuninzi bomthamo we-0.4 ~ 1.0g / cm3) kunye ne-ultra-low light refractories (ubuninzi bevolumu ngaphantsi kwe-0.4g / cm3).
(3) Ngokwemathiriyeli ekrwada yahlulwe ngodongwe, i-aluminiyam ephezulu, isilicon kunye ne-magnesium ubushushu bezinto zokunqanda ubushushu.
(4) Ngokwendlela yokuvelisa, yahlulwe ngendlela yokongeza ukutshiswa, indlela ye-foam, indlela yeekhemikhali kunye ne-porous material method kunye nezinye izinto zokunqanda ukugquma kwe-thermal.
(5) ngokwemilo yeemveliso yahlulwe ngokwemilo yokugquma ubushushu imveliso refractory kunye amorphous ubushushu imveliso refractory.
Iimveliso ze-refractory zokufakelwa kwe-thermal kunye neemveliso ezishinyeneyo zokuchasa zahlukile, ezona ndlela ziphambili yindlela yokongeza yokudinwa, indlela yogwebu, indlela yekhemikhali kunye nendlela yemathiriyeli enemingxuma:
