Silicon Carbide SSIC RBSIC SiC Tube Umbhobho weSilicon
I-silicon carbide engenaxinzelelo (SSIC)iveliswa kusetyenziswa umgubo we-SiC ocolekileyo kakhulu oqulethe izongezo ze-sintering. Icutshungulwa kusetyenziswa iindlela zokubumba eziqhelekileyo kwezinye iiseramics kwaye i-sintered kwi-2,000 ukuya kwi-2,200 ° C kwi-atmosphere ye-inert yegesi.Kwakunye neenguqulelo ezicokisekileyo, ezinobukhulu obuziinkozo <5 um, iinguqulelo ze-coarse-grained kunye nobukhulu beenkozo ukuya kwi-1.5. mm ziyafumaneka.
I-SSIC yohlulwa ngamandla aphezulu ahlala phantse ngokuthe rhoqo ukuya kumaqondo obushushu aphezulu kakhulu (malunga ne-1,600° C), egcina loo mandla ixesha elide!
Iinzuzo zemveliso:
Ukumelana ne-oxidation yobushushu obuphezulu
Uxhathiso olugqwesileyo lweCorrosion
Ukuxhathisa okulungileyo kweAbrasion
I-coefficient ephezulu yokushisa ukushisa
Ukuzithambisa, ukuxinana okuphantsi
Ukuqina okuphezulu
Uyilo olulungiselelweyo.
