Hongchang ngwaahịa ezinụlọ ekpuchi mgbanwe carbon eriri chere, graphite chere, isiike mejupụtara mmetụta, carbon ákwà, carbon eriri, graphite akwụkwọ, batrị chere, quartz crucibles na mkpuchi ihe ngwọta maka photovoltaic, semiconductor, agụụ ọkụ na ume ngwa.
Chọgharịa ezinụlọ ihe onwunwe Hongchang maka mkpuchi okpomọkụ dị elu, nchekwa ebe okpomọkụ na iji akụrụngwa ike.
Viscose dabeere na carbon fiber graphite chere nwere mpe mpe mpe mpe mpe akwa. Site n'ịkwa akwa a na-achịkwa, ịkụ ọkpọ na graphitization usoro, ngwaahịa ahụ na-enweta conductivity dị ala, njupụta kwesịrị ekwesị na ezigbo nguzogide oxidation.
A na-eme fiber graphite tupu oxidized site na eriri dabere na polyacrylonitrile site na pre-oxidation, crimping, ịcha, ọkpọ ọkpọ, carbonization na graphitization. E jiri ya tụnyere graphite dabere na PAN, ọ na-enye njupụta dị ala, ịdị nro ka mma na ịdị ala…
A na-eme eriri carbon nke nwere PAN sitere na eriri polyacrylonitrile sitere na usoro enweghị akwa na usoro ịkụ ọkpọ. Mgbe ejiri ya tupu oxidation, carbonization na graphitization, ọ na-aghọ ihe mkpuchi ọkụ na-ekpo ọkụ na-ekpo ọkụ.
Kekọrịta ngwa ahụ, ụdị ọkụ, okpomọkụ na-arụ ọrụ, ọkpụrụkpụ, obosara, ịdị ọcha na ọnọdụ nrụnye. Hongchang nwere ike inye aka dakọtara mmetụta dabara adaba, mkpuchi ihe mejupụtara ma ọ bụ ezinụlọ ihe ọkụkụ carbon.
