I. Gabatarwa ga gilashin tsarin carbon
Halaye:
(1) Fuskar carbon gilashi yana da santsi kuma yana da tsarin gilashi;
(2) Gilashin carbon yana da babban tauri da ƙarancin ƙura;
(3) Glassy carbon yana da babban darajar ID / IG da ƙananan digiri na graphitization, kuma aikin sa na thermal yana da kyau;
(4) Gilashin carbon ne mai wuya-zuwa-graphitize carbon tare da mai kyau high zafin jiki juriya da kuma karfi da kwanciyar hankali a high yanayin zafi;
(5) Gilashin carbon yana da ƙaramin yanki na amsawa da kyakkyawan juriya na lalata sinadarai, kuma ya fi juriya ga yashwar oxygen, silicon, da sauransu.
II. Gabatarwa zuwa gilashin murfin carbon
Ana rarraba pores na fasinja na flake graphite kuma tsarin yana da sako-sako, yayin da tsarin murfin carbon gilashin yana da ƙarfi kuma baya faɗi!
1. Anti-oxidation yi na gilashin gilashin carbon
(1)Laminated tsananin ji
Gilashin carbon da aka shafa da kyau yana inganta aikin anti-oxidation na ji mai ƙarfi;
(2)Short fiber wuya ji
Gaba ɗaya ji yana da babban porosity kuma yana samar da tashoshi na oxygen; da flake graphite shafi yana da sako-sako da tsarin, m oxygen tashoshi, da kuma inganta anti-oxidation yi; murfin carbon da aka rufe da gilashi yana da tsari mai yawa, ƙananan tashoshi na oxygen, da mafi kyawun aikin anti-oxidation.
2. High-zazzabi kwanciyar hankali na gilashin carbon shafi a kan ablation
Siffar porous na a fili ji na iya rage zafi (zafi convection zafi dissipation); Takardar graphite tana da saurin kamuwa da blister idan an soke; zurfin ablation na gilashin gilashin carbon shine mafi ƙanƙanta, kuma juriya na haɓaka shine mafi ƙarfi; gilashin gilashin gilashin carbon yana da kyakkyawan aikin rufewa na thermal.
3. Anti-Si yashewa yi na gilashin carbon shafi
Short fiber wuya ji yana lalacewa da foda ta Si; flake graphite shafi yana da juriya ga yashewar Si a cikin gajeren lokaci; gilashin gilashin carbon yana da mafi kyawun aikin anti-barazawa.
Babban dalilin da yashewar Si shine cewa Si gasification kai tsaye yana lalatar da saman ji mai tauri, yana haifar da foda; yayin da tsarin carbon na gilashin gilashin gilashin carbon yana da kwanciyar hankali kuma yana da mafi kyawun aikin anti-barazawa.
Takaitawa
The gilashin carbon rufi tsarin ba kawai amfani da thermal rufi kayan, amma kuma ana sa ran za a yi amfani da kai tsaye a saman graphite sassa da kuma.C/C sassa, inganta ingantaccen aikin sabis na kayan.
