Izitini eziphezulu ze-aluminiyamu ezingasindi zokufaka izinto ezishisayo ziyimikhiqizo ephikisayo evimbela ukushisa eyenziwe nge-bauxite njengento eluhlaza eyinhloko enokuqukethwe kwe-Al2O3 okungengaphansi kuka-48%. Inqubo yokukhiqiza yayo iyindlela yegwebu, futhi ingaba yindlela yokwengeza eshisiwe. Isitini esiphezulu se-aluminium engasindi sokufakelwa singasetshenziselwa izendlalelo ze-masonry insulation kanye nezingxenye ngaphandle kokuguguleka okunamandla nokuguguleka kwezinto ezincibilikisiwe ezisezingeni eliphezulu. Lapho uthintana ngqo namalangabi, ngokuvamile izinga lokushisa elingaphezulu le-aluminium ephezulu ye-lightweight insulation akumele libe ngaphezu kuka-1350 °C.
Izici zezitini eziphezulu ze-aluminium lightweight insulation
Inezici zokumelana nokushisa okuphezulu, amandla aphezulu, ukuminyana kwenqwaba ephansi, i-porosity ephezulu, ukuhanjiswa kwe-thermal okuphansi, ukumelana nokushisa okuphezulu, nokusebenza okuhle kokufakwa kokushisa. Inganciphisa usayizi nesisindo semishini eshisayo, ifinyeze isikhathi sokushisa, iqinisekise izinga lokushisa elilinganayo lesithando somlilo, futhi inciphise ukulahlekelwa ukushisa. Ingonga amandla, yonge izinto zokwakha zesithando somlilo futhi yandise impilo yesevisi yesithando somlilo.
Ngenxa ye-porosity yayo ephezulu, ukuminyana kwenqwaba ephansi kanye nokusebenza okuhle kokufakwa kwe-thermal,high aluminium lightweight insulation izitinizisetshenziswa kabanzi njengezinto ezishisayo zokugcwalisa ukufakwa kwe-thermal endaweni ephakathi kwezitini eziphikisayo nezidumbu zomlilo ngaphakathi kwamahhoko ahlukahlukene ezimboni ukuze kuncishiswe ukushiswa kokushisa kwesithando somlilo nokuthola amandla aphezulu. Iphuzu lokuncibilika kwe-anorthite ngu-1550°C. Inezici zokuminyana okuphansi, i-coefficient encane yokunwetshwa kokushisa, ukuhanjiswa kwe-thermal okuphansi, nokuba khona okuzinzile ekunciphiseni umkhathi. Ingangena esikhundleni sobumba, i-silicon, nezinto eziphikisayo ze-aluminium ephezulu, futhi ibone ukonga amandla nokunciphisa ukukhishwa.
