Qoysaska wax soo saarka Hongchang waxay daboolaan fiber-karboonka dabacsan ee dareema, graphite dareemay, dareemo isku dhafan oo adag, maro kaarboon, xadhig kaarboon, warqad graphite ah, baytari dareemay, quartz crucibles iyo xalalka daahan ee photovoltaic, semiconductor, foornada vacuum iyo codsiyada tamarta.
Ka baadh qoysaska maaddada Hongchang si aad u hesho dahaarka heerkulka sare, ilaalinta goobta kulaylka iyo isticmaalka qalabka tamarta.
Dareemka viscose-ku-salaysan ee aadka u dhumucdiisuna wuxuu leeyahay cilladaha fiber-ka oo yar. Iyada oo loo marayo tolida la kontoroolo, irbad-feerista iyo hababka garaafyada, waxay ku guulaysataa kuleylka kuleylka hooseeya, cufnaanta ku habboon iyo caabbinta oksaydhka wanaagsan.
Daahan cusub ee ka-hortagga oksaydhka iyo dahaarka u adkaysta ayaa lagu dabaqaa dusha adag ee la dareemay si loo hagaajiyo ilaalinta dusha sare ee u baahan xaaladaha adeegga heerkulka sare.
La wadaag arjiga, nooca foornada, heerkulka shaqada, dhumucda, ballaca, nadiifinta iyo xaaladaha rakibidda. Hongchang waxay gacan ka geysan kartaa iswaafajinta dareenka ku habboon, dahaarka isku-dhafka ah ama qoyska maaddada fiber-carbon.
