Zingaphi iimullite ezilula zokugquma izitena zokumelana?
Zingaphi iimullite ezilula zokugquma izitena zokumelana?
Izitena zokwambathisa iMullite luhlobo olutsha lwezinto ezinqabileyo, ezinokunxibelelana ngqo nelangatye. Inempawu zokumelana nobushushu obuphezulu, ukukhanya okuphezulu, ukuqhuba okuphantsi kwe-thermal, kunye nefuthe lokonga amandla. Izitena ze-Mullite ezilula zokuthambisa zinobunjani bokusebenza kakuhle kobushushu obuphezulu kunye nexabiso eliphantsi. Zingasetyenziselwa iilensi zelensi, ezingenakuphelisa kuphela umgangatho wobushushu besithando somlilo, ukugcina ucinezelo, kodwa kunye nokwandisa ubomi benkonzo yomngxunya wesithando somlilo kunye nokunciphisa iindleko zokugcina.
Izitena ze-Mullite ezingasindi kakhulu zenziwe nge-bauxite, udongwe, “amatye amathathu”, njl., Ngokwenza inani elikhulu lezinto ezidityanisiweyo okanye ezivaliweyo ekubunjweni kwezinto okanye kwinkqubo yokutshisa ubushushu obuphezulu.
Iimpawu mullite izitena yokugquma engasindi:
Zingaphi iimullite ezilula zokugquma izitena zokumelana? Ukuxhathisa kobushushu obuphezulu bezitena zokugquma ukukhanya kwe-mullite kunokufikelela ngaphezulu kwe-1790 ℃. Ubushushu obuqala ukuthambisa umthwalo ngu-1600-1700 ℃, ubushushu obuqhelekileyo bokucinezelwa kwamandla yi-70-260MPa, ukumelana nokuothuka kwe-thermal kulungile, amandla aphezulu, iqondo lokunyuka kweqondo lobushushu liphezulu, umlinganiso wolwandiso uphantsi, umlingani wobushushu incinci, kwaye i-acid slag iyamelana. Kwaye bunokubunciphisa kakhulu ubunzima bomzimba obushushu obuphezulu, ukuguqula ulwakhiwo, ukugcina izinto, ukugcina amandla, kunye nokuphucula ukusebenza kwemveliso.
Uluhlu lwesicelo sezitena ezincinci zokuthambisa:
Izitena ze-Mullite ezingasindi kakhulu zisetyenziselwa iifanitshala ezinobushushu obungaphezulu kwe-1400 ℃, uphahla lobushushu obuphezulu, ubushushu, iirgenerator arches, izakhiwo zeglasi ezinyibilikisa amaziko, iiceramic kilting sistering, iiceramic roller kilns, itonela kilns, Ingaphakathi langaphakathi le porcelain yombane eziko ledrowa, ikona efileyo yesithambiso sombane yenkqubo yokuqhekeka kwepetroleum, iziko lokubilisa iglasi kunye nomlilo ohlukeneyo wombane unokuqhagamshelana ngqo nelangatye.
Izalathiso zomzimba kunye nezemichiza yesitena sokukhanya esenziwe mullite:
