Carbon / carbon composite(zvino zvichinzi "C / C kana CFC") imhando yezvakaumbwa zvinhu zvakavakirwa pakabhoni uye inosimbiswa nekabhoni fiber uye zvigadzirwa zvayo (carbon fiber preform). Iine zvose inertia yekabhoni uye simba rakakwirira re carbon fiber. Iyo ine yakanaka yemagetsi zvivakwa, kupisa kupisa, corrosion resistance, friction damping uye thermal uye magetsi conductivity maitiro.
CVD-SiCCoating ine hunhu hwechimiro chakafanana, compact material, yakakwirira tembiricha kuramba, oxidation kuramba, kuchena kwakanyanya, acid & alkali kuramba uye organic reagent, ine yakagadzikana yemuviri nemakemikari zvinhu.
Main features:
1. High tembiricha oxidation kuramba:iyo oxidation kuramba ichiri yakanaka kwazvo kana tembiricha yakakwira kusvika 1600 C.
2. Kuchena kwepamusoro: yakagadzirwa nemakemikari vapor deposition pasi pekushisa kwakanyanya kweklorination mamiriro.
3. Erosion resistance: high hardness, compact surface, fine particles.
4. Corrosion resistance: acid, alkali, munyu uye organic reagents.

VET Energy ndiyo chaiyo inogadzira yakagadziridzwa magirafu uye silicon carbide zvigadzirwa zvine machira akasiyana seSiC coating, TaC coating, girazi kabhoni coating, pyrolytic kabhoni coating, nezvimwewo, inogona kupa akasiyana akagadziridzwa zvikamu zve semiconductor uye photovoltaic indasitiri.
Chikwata chedu chehunyanzvi chinobva kumasangano epamusoro ekutsvagisa dzimba, anogona kukupa mamwe hunyanzvi zvigadziriso zvekushandisa kwauri.
Isu tinoramba tichigadzira maitiro epamberi ekupa zvimwe zvepamberi zvinhu, uye takagadzira yakasarudzika tekinoroji, iyo inogona kuita kuti chisungo pakati pekupotera neiyo substrate ive yakasimba uye isinganyanye kubatwa.
Tikugashirei noushamwari kuti ushanyire fekitari yedu, ngativei neimwe hurukuro!
