Izinto eziluncedo ezintandathu zoxinzelelo lwe-atmospheric sintered silicon carbide kunye nokusetyenziswa kwesilicone carbide ceramics.

Uxinzelelo lwe-Atmospheric sintered silicon carbide ayisasetyenziswa nje njenge-abrasive, kodwa ngakumbi njengesixhobo esitsha, kwaye isetyenziswa ngokubanzi kwiimveliso zobuchwepheshe obuphezulu, ezifana neeseramics ezenziwe nge-silicon carbide materials. Ke zeziphi iingenelo ezintandathu zoxinzelelo lwe-atmospheric sintering silicon carbide kunye nokusetyenziswa kwe-silicon carbide ceramics?

Izinto eziluncedo ezintandathu zoxinzelelo lwe-atmospheric sintered silicon carbide materials:

1. Ubuninzi obuphantsi

I-silicon carbide imathiriyeli inoxinano olusezantsi kunentsimbi, yenza isixhobo sibe lula.

2. Ukumelana nokubola

Izinto zeSilicon carbide zinendawo ephezulu yokunyibilika, inertia yeekhemikhali, ukuxhathisa ukothuka kwe-thermal, i-silicon carbide isetyenziswa kwi-abrasives, i-ceramic kilns, i-silicon carbide blanks, ingasetyenziselwa kwishishini lokunyibilikisa kunye nokunyibilikisa nge-cylinder vertical distillation furnace, izitena, i-aluminium electrolytic cell linening. , i-tungsten, i-furnace encinci kunye nezinye iimveliso ze-silicon carbide ceramic.

I-3, ubushushu obuphezulu, i-coefficient yokwandisa i-thermal iyancitshiswa

Izinto ze-silicon ze-carbide zenziwe kumaqondo aphezulu. Kwezinye iimeko zobushushu obuphezulu, izinto ezifuna amandla okusebenza kunye nokuchaneka kokusetyenzwa kwe-silicon carbide ceramics ziyafuneka. Ukushisa okuphezulu kwe-silicon carbide malunga ne-800, kwaye iqondo lokushisa lensimbi liyi-250 kuphela. Ukubala okugwenxa, i-coefficient yokwandisa i-thermal ye-silicon carbide kwi-25 ~ 1400 yi-4.10-6 / C. I-coefficient yokwandisa i-thermal ye-silicon carbide ilinganiswa, kwaye iziphumo zibonisa ukuba inani lincinci kakhulu kunezinye iibrasives kunye nezixhobo zokushisa eziphezulu. I-silicon carbide ye-Sintered phantsi koxinzelelo lwe-atmospheric

I-4, i-thermal conductivity ephezulu

I-thermal conductivity yezinto ze-silicon carbide ziphezulu, enye into ebalulekileyo kwiipropati ezibonakalayo ze-silicon carbide. I-thermal conductivity ye-silicon carbide inkulu kakhulu kunezinye i-refractories kunye ne-abrades, malunga namaxesha angama-4 e-corundum. I-Silicon carbide ine-coefficient ephantsi yokwandiswa kwe-thermal kunye ne-conductivity ephezulu ye-thermal, ngoko i-workpiece iya kuba phantsi koxinzelelo oluncinci lwe-thermal ngexesha lokufudumala kunye nokupholisa. Kungenxa yoko le nto amacandelo e-SiC exhathisa ngokukodwa ukothuka.

I-5, amandla omatshini aphezulu, ukuqina okuhle

Amandla omatshini wezinto ze-silicon carbide ziphezulu kakhulu, zithintela ukuguqulwa kwezinto. I-silicon carbide inamandla omatshini aphezulu kune-corundum.

I-6, ubunzima obuphezulu kunye nokumelana nokunxiba

Ubunzima bezinto ze-silicon carbide ziphezulu kakhulu, kwaye ubunzima be-gap ye-Moss yi-9.2 ~ 9.6, okwesibini kuphela kwi-diamond kunye ne-tungsten carbide. Xa kuthelekiswa nezixhobo zetsimbi zetsimbi, ibonelela ngobulukhuni obuphezulu, i-coefficient ephantsi ye-friction, i-friction ephantsi ngokwentelekiso, uburhabaxa obuncinci bomgangatho kunye nokumelana nokunxiba kakuhle ngaphandle kokuthambisa. Ukongezelela, ichasene nezinto zangaphandle, ukuphucula ukunyamezela komhlaba. I-silicon carbide ye-Sintered phantsi koxinzelelo lwe-atmospheric

Ukusetyenziswa koxinzelelo lwe-atmospheric sintered silicone carbide ceramics

I-1, imveliso ye-silicon carbide ye-ceramics ekhethekileyo

Izinto zeSilicon carbide zizixhobo ezinobunzima obuphezulu kunye neendleko eziphantsi, ezinokuvelisa iimveliso ze-silicon carbide, ezifana ne-silicon carbide seals, imikhono ye-silicon carbide, iipleyiti ze-silicon carbide bulletproof, iiprofayili ze-silicon carbide, njl. iimpompo ezahlukeneyo. I-silicon carbide ye-Sintered phantsi koxinzelelo lwe-atmospheric

I-2, imveliso ye-zirconia yezinto zeeramics ezikhethekileyo

I-Zirconia ceramic ine-conductivity ephezulu ye-ionic, uzinzo oluhle lweekhemikhali kunye nozinzo lwesakhiwo, kwaye ibe yinto efundwa ngokubanzi kwaye isetyenziswe i-electrolyte. Ngokuphucula inkqubo yokwenziwa kwefilimu ye-zirconia esekelwe kwi-electrolyte, ukunciphisa ubushushu bokusebenza kunye neendleko zokwenziwa kwezi zinto, kunye nokuzama ukuphumeza ushishino lukwayindlela ebalulekileyo yophando lwexesha elizayo.
