Cholimba, chosalowa madzi komanso chosawonongeka, komanso chatsopano cha silica graphite. Chithunzi Chowonetsedwa

Kufotokozera Kwachidule:

Ningbo VET Energy Technology Co., Ltd. ndi kampani yapamwamba yokhazikitsidwa ku China. Ndife opanga akatswiri komanso ogulitsa zinthu za Graphite silicide.

Graphite yokhala ndi silicon ndi chinthu chophatikizika chomwe silicon carbide imalumikizidwa pamwamba pa graphite substrate. Ili ndi mawonekedwe a kuuma kwambiri, mphamvu yayikulu yamakina komanso kukana kusweka kwa silicon carbide, komanso mphamvu zodzipaka mafuta komanso kukana kutentha kwa graphite. Ndi zipangizo zabwino kwambiri zokangana ndi zida zosindikizira zamakina, zoyenera kutseka mapampu osiyanasiyana amadzi, mapampu amafuta, mapampu a mankhwala, ndi ma bearing a mapampu osiyanasiyana othamanga kwambiri komanso olemera kwambiri. Kuphatikiza apo, graphite yokhala ndi silicon ili ndi kukana kwabwino kwa okosijeni, kukana kutentha, kutsika kwa porosity, komanso kuyendetsa magetsi, ndipo ingagwiritsidwe ntchito ngati zipangizo monga zitsulo zosungunulira zitsulo ndi machubu odulira.

Kapangidwe ka siliconizedGraphite ndi yofanana, pamwamba pake pamagwirizana ndi mkati, ndipo chiŵerengero cha kapangidwe ka silicon carbide ndi graphite chimasinthika. Kachulukidwe ka silicon carbide kakachuluka, kuchuluka kwa zinthuzo kumakulirakulira, mphamvu yopondereza imakwera, ndipo mphamvu yotsutsa imawonjezeka.

(gawo lakuda ndi graphite, gawo la imvi ndi silicon carbide, ndipo gawo loyera ndi silicon)
