Kutentha kwambiri komanso kugonjetsedwa ndi dzimbiri, silika graphite crucible ndi yabwino kusungunuka zitsulo

Kufotokozera Kwachidule:

Ningbo VET Energy Technology Co., Ltd. ndi bizinesi yapamwamba yomwe idakhazikitsidwa ku China. Ndife akatswiri opanga komanso ogulitsa zinthu za silika za Graphite.

Silicone graphite ndi zinthu zophatikizika zomwe silicon carbide imamangiriridwa pamwamba pa gawo lapansi la graphite. Ili ndi mawonekedwe a kuuma kwakukulu, mphamvu zamakina apamwamba komanso kukana kwa silicon carbide, komanso kudzipangira mafuta komanso kukana kugwedezeka kwa graphite. Ndi zida zoyenera zomangirana ndi zida zamakina zosindikizira, zoyenera kusindikiza pamakina a mapampu osiyanasiyana amadzi, mapampu amafuta, mapampu amankhwala, ndi mayendedwe a mapampu osiyanasiyana othamanga kwambiri komanso olemetsa kwambiri. Komanso, siliconized graphite ali wabwino makutidwe ndi okosijeni kukana, matenthedwe kukana mantha, otsika porosity, ndi madutsidwe magetsi ena, ndipo angagwiritsidwe ntchito ngati zipangizo monga zitsulo smelting crucibles ndi draft machubu.

Siliconized Graphite (1)

Kupanga kwa siliconizedgraphite ndi yunifolomu, pamwamba n'zogwirizana ndi mkati, ndi zikuchokera chiŵerengero cha silicon carbide ndi graphite ndi chosinthika. Kukwera kwa silicon carbide, kuchulukirachulukira kwa zinthuzo, kumapangitsanso mphamvu yopondereza, komanso kulimbikira kumawonjezeka.
