Zvinhu zvinosanganisa kabhoni/kabhoni(zvino zvichinzi "C / C kana CFC") imhando yezvinhu zvakasanganiswa zvakagadzirwa nekabhoni uye zvinosimbiswa nekabhoni fiber nezvigadzirwa zvayo (kabhoni fiber preform). Ine simba rekabhoni uye simba rayo guru. Ine hunhu hwakanaka hwemakanika, inodzivirira kupisa, inodzivirira ngura, inodzivirira kukweshana uye hunhu hwekupisa uye magetsi.
CVD-SiCKuputira kune hunhu hwechimiro chakafanana, zvinhu zvidiki, kuramba kupisa kwakanyanya, kuramba oxidation, kuchena kwakanyanya, kuramba acid & alkali uye reagent yeorganic, ine hunhu hwakagadzikana hwemuviri nemakemikari.
Zvinhu zvikuru:
1. Kudzivirira kupisa kwakanyanya kwe oxidation:Kusakwanisa kuoxidation kuchiri kwakanaka zvikuru kana tembiricha yakakwira kusvika 1600 C.
2. Kuchena kwakanyanya: kunogadzirwa nekuiswa kwemhepo ine makemikari pasi pemamiriro ekupisa kwakanyanya.
3. Kuramba kukurwa kwevhu: kuomarara kwakanyanya, pamusoro pakaoma, zvidimbu zvitete.
4. Kuramba ngura: acid, alkali, munyu uye organic reagents.

VET Energy ndiyo kambani chaiyo inogadzira zvigadzirwa zve graphite ne silicon carbide zvakagadzirwa ne SiC coating, TaC coating, glassy carbon coating, pyrolytic carbon coating, nezvimwewo, inogona kupa zvikamu zvakasiyana-siyana zvakagadzirwa ne semiconductor ne photovoltaic industry.
Chikwata chedu chehunyanzvi chinobva kumasangano makuru ekutsvagisa emuno, chinogona kukupa mhinduro dzehunyanzvi.
Tinogara tichigadzira maitiro epamusoro-soro kuti tipe zvinhu zvepamusoro-soro, uye takagadzira tekinoroji yakasarudzika ine patent, iyo inogona kuita kuti kubatana pakati pe coating ne substrate kuve kwakasimba uye kusanyanya kupatsanurwa.
Tinokugamuchirai neushamwari kuti mushanyire fekitori yedu, ngatikurukurei zvakawanda!
