Izitena zeBhola eHollow eNxulutywayo yokuKhusela
Ukuhlelwa
Izitena zebhola ze-alumina&Zirconia zebhola enomngxuma izitena
inkcazelo
Izitena zebhola ze-alumina ezingenanto zenziwe nge-alumina ibhola engenanto kunye nomgubo we-alumina njengeyona nto iphambili ekrwada, idityaniswe nenye i-binder, emva kwe-1750 degrees yokudubula kobushushu obuphezulu, yeyohlobo lobushushu obuphezulu kunye nemathiriyeli yokugcina amandla.
Iimbonakalo
Izitena zebhola ze-alumina ezingenanto ziqulethe inani elikhulu le-porosity evaliweyo, ngoko ke inamandla aphezulu kunye nokuzinza kwesakhiwo se-porosity, ubuninzi obuphantsi, ukuxhathisa ukothuka kwe-thermal kunye notshintsho oluncinci lwe-linear esisigxina, i-conductivity ephantsi ye-thermal.
Izitena zebhola zeZirconia ezingenanto ezinokumelana nobushushu obuphezulu, ukuxhathisa ukubola kweekhemikhali, ukumelana ne-oxidation, ukuxhathisa ukunxiba, ukwanda okukhulu kwe-thermal.Iimveliso zebhola ze-Zirconia ezingenanto ezenziwe ngokupheleleyo yibhola ye-zirconia engenanto, enegunya elihle lobushushu obuphezulu kunye nokuzinza kwesakhiwo se-porosity.
Isicelo
Izitena zebhola ze-alumina ezingenanto zisetyenziswa ikakhulu kwi-gasifier reactor kushishino lwepetrochemical, ishishini lekhabhoni emnyama, iziko lokungeniswa kwishishini lesinyithi, i-oven-draft kiln, i-shuttle kiln, i-molybdenum wire furnace, i-tungsten rod furnace, i-oven ye-nitrogenation, kunye nezinye. iqondo lobushushu, amaziko obushushu aphezulu aphezulu.
Izitena zebhola ze-Zirconia ezingenanto zisetyenziswa kwizixhobo zokushisa eziphezulu ezifana neendawo zokugubungela i-thermal insulation, ezifana nesithando somlilo esiphakathi, i-carbon black reactor, i-molybdenum wire furnace, i-tungsten intonga yomlilo, njl. ubushushu bokusebenza yi-2200 ℃, kwi-metallurgical, petrochemical, electronic and other industrial equipment thermal equipment njengonxibelelwano oluthe ngqo nedangatye lezinto zombane eziphezulu, isiphumo esihle sokusetyenziswa.
