umgubo we-alumina ongqukuva
Ingcaciso yeMveliso
I-alumina eyi-Spherical yimathiriyeli esebenza kakhulu enobunyulu obuphezulu, amasuntswana angqukuva, ubunzima obuphezulu, ukumelana nokunxiba okuphezulu, ukumelana nokugqwala okuphezulu, ukuzinza okuphezulu kwe-thermal kunye nokufakwa kakuhle kombane.I-alumina eyi-Spherical inobunzima obuphezulu kunye namandla, nto leyo eyenza ukuba ibe yinto efanelekileyo yokunxiba.Kwimimandla yeeseramics, i-electronics, imboni yeekhemikhali kunye nokwakhiwa, i-alumina engqukuva isetyenziswa ngokubanzi ekwenzeni izinto ezenziwe nge-ceramic ezikumgangatho ophezulu, iibheringi ezixhathisayo zokunxiba, iinxalenye eziphambili zeenjini zeemoto, njl. njl. gcina ukusebenza okuzinzileyo kwiindawo ezinzima.Ngokomzekelo, kwindawo yaseLwandle, imboni yeekhemikhali, imboni yamandla kunye nezinye iindawo, i-alumina ye-spherical isetyenziselwa ukuveliswa kweenqanawa, izixhobo zeekhemikhali, izixhobo zamandla njalo njalo.I-alumina eyi-Spherical inozinzo oluhle lwe-thermal kunye nokufakelwa kombane, ukuze ikwazi ukugcina ukusebenza okugqwesileyo kubushushu obuphezulu kunye neendawo zoxinzelelo oluphezulu.Kwinkalo yezobuchwephesha, i-alumina engqukuva isetyenziswa ekwenzeni izixhobo zombane ezinobushushu obuphezulu, izixhobo zamandla ombane aphezulu, njl.

Iimpawu zeMveliso
Ukuzaliswa okuphezulu: Izinga eliphezulu le-spheroidization rate, ukusabalalisa ubungakanani be-particle ukuhanjiswa, ukufezekisa ukuzaliswa koxinaniso oluphezulu lwe-silicone kunye ne-epoxy resin, ukufumana umxube kunye ne-viscosity ephantsi kunye nokuhamba okuphezulu;
I-High Thermal Conductivity: Ngenxa yesakhiwo sayo esiphantse sigqibelele sebhola, isigcwalisi esisetyenziswe kwizinto eziluhlaza sinokufikelela kwi-multi-directional heat transmission.Yonke inkqubo edibeneyo ikwimeko yokusasazwa okulungileyo, ngoko ke iimveliso zokugqibela zine-conductivity egqwesileyo ye-thermal kunye nepropathi ebonakalayo;
I-Abrasion ephantsi: xa kuthelekiswa nomgubo ongaqhelekanga, ukusetyenziswa kwe-spherical filler kunokunciphisa i-abrasion yomxube, oomatshini bokubumba kunye nezinye izixhobo, emva koko bandise ubomi bokusebenza kwezixhobo ezifanelekileyo.
