Sintered Silicon Carbide Ceramic Bushing
Pressureless sintered silicon carbide (SSIC)amapangidwa pogwiritsa ntchito ufa wabwino kwambiri wa SiC wokhala ndi zowonjezera zowonjezera. Amakonzedwa pogwiritsa ntchito njira zopangira zitsulo zina zadothi ndikuthiridwa pa 2,000 mpaka 2,200 ° C mu mpweya wa mpweya wopanda mpweya. Komanso matembenuzidwe abwino kwambiri, okhala ndi kukula kwa tirigu <5 um, mitundu yolimba-grained yokhala ndi kukula kwambewu mpaka 1.5. mm zilipo.
SSIC imasiyanitsidwa ndi mphamvu yayikulu yomwe imakhala pafupifupi nthawi zonse mpaka kutentha kwambiri (pafupifupi 1,600 ° C), kusunga mphamvuzo kwa nthawi yayitali!
Ubwino wazinthu:
Kutentha kwakukulu kwa okosijeni kukana
Zabwino kwambiri Corrosion resistance
Good Abrasion resistance
High coefficient of conductivity kutentha
Kudzipangira mafuta, kutsika kochepa
Kuuma kwakukulu
Mapangidwe mwamakonda.
