Inxalenye yeAlumina yeCeramic ye-Insulator
Indawo yosetyenziso
Iiseramikhi zealumina ezisetyenziswa ngokubanzi kwisigqubuthelo esinepropathi ephezulu yoomatshini, ubulukhuni obuphezulu, ukunxiba ixesha elide, ukuxhathisa okukhulu kokugqunyelelwa, uthintelo olululo lokutya, ukumelana nobushushu obuphezulu.
Iiseramikhi zealuminaiinxalenyenazoan izicelo ezibalulekileyo kwintsimi yokugquma.Umzekelo, kwintsimi ye-aerospace, ii-alumina-based fibers zingasetyenziselwa ukwenza izinto zokugquma ezishushu ezifana neethayile ezinganyangekiyo ubushushu kunye nezinto eziguquguqukayo zokugquma kwi-shuttles, izithintelo ezishushu kwiinjini zerokethi, kunye nezixhobo zokugquma ubushushu obuphezulu kwinqwelomoya. iinjini.
Fokanye enye indawo,iiseramikhi zealuminaiinxalenyeinokusetyenziswa njengezinto zokufakelwa kwe-thermal kwiziko lobushushu obuphezulu.Ifiber emfutshane ye-alumina-based composite imathiriyeli ineengenelo zokuxinana okuphantsi, ukugqunywa kakuhle, kunye nomthamo ophantsi wobushushu, obunokunciphisa ubunzima beziko lobushushu obuphezulu.Okuninzikwaye wenze ulawulo lobushushu luchaneke ngakumbi,ngoko iyakwazisaveamandla amaninzi.
I-alumina / imathiriyeli edibeneyo ye-resin nayo inokusebenza kakuhle kokugquma.Esi sixhobo sineempawu zokwaluka, ubunzima obuphezulu, kwaye sinokusetyenziswa ekwenzeni izixhobo zemidlalo ezifana neentonga zokuloba, iiklabhu zegalufa, iskis, kunye neereyithi zentenetya.
Fngokuthetha ngokunyanisekileyo,ukusetyenziswa kweekeramics ze-alumina kwintsimi yokugqumaunakouncedo ekuphuculeni ukusebenza kunye nobomi bezixhobo, ngelixa kunciphisa ukusetyenziswa kwamandla.So It iya kubaukubaluleka okulungileyo ekukhuthazeni uphuhliso oluzinzileyo kunye nokhuseleko lokusingqongileyo.
Iinkcukacha
Ubungakanani obufunekayo:I-1pc ukuya kwi-1 yezigidi zeepcs.Akukho MQQ ilinganiselwe.
Ixesha lesampula lesampulu:ukwenza izixhobo yi-15days + isampuli yokwenza 15days.
Ixesha lemveliso:15 ukuya 45days.
Ixesha lokuhlawula:uthethathethwano ngamaqela omabini.
Inkqubo yokuvelisa:
I-Alumina(AL2O3) i-ceramic yi-ceramic yoshishino enobunzima obuphezulu, ukunxiba ixesha elide, kwaye inokwakheka kuphela ngokusila idayimani.Iveliswa kwi-bauxite kwaye igqitywe ngokubumba, ukucofa, ukucwina, ukucola, ukuthunga kunye nenkqubo yokwenza.
