Olee otú iji zere corrosion nke ngwá site ike corrosive media, ka ibelata akụrụngwa ego na mmezi ụgwọ ma melite mmepụta arụmọrụ na uru bụ a siri ike nsogbu na ọ bụla chemical Enterprise kwesịrị idozi ruo mgbe ebighị ebi. Ọtụtụ ngwaahịa nwere nguzogide corrosion mana ọ bụghị oke okpomọkụ, ebe flake graphite nwere uru abụọ ahụ. Furuite na-esonụGraphitena-ewebata n'ụzọ zuru ezu ka flake graphite nwere ike isi dozie nsogbu corrosion nke akụrụngwa:
1. Mma mma thermal conductivity.Akara graphitenwekwara ezi thermal conductivity, nke bụ naanị ihe na-abụghị ọla na elu thermal conductivity karịa metal, ogo mbụ n'etiti ndị na-abụghị ọla ihe. The thermal conductivity bụ okpukpu abụọ nke carbon ígwè na ugboro asaa nke igwe anaghị agba nchara. Ya mere, ọ dị mma maka ngwa nnyefe okpomọkụ.
2. Magburu onwe corrosion eguzogide. Dị iche iche iche iche nke carbon na graphite nwere magburu onwe corrosion iguzogide niile ịta nke hydrochloric acid, phosphoric acid na hydrofluoric acid, gụnyere fluorine-nwere media, na kasị elu ngwa okpomọkụ bụ 350 ℃-400 ℃, ya bụ, okpomọkụ nke carbon na graphite amalite oxidize.
3, na-eguzogide ụfọdụ okpomọkụ dị elu. Ojiji okpomọkụ nke graphite flake na-adabere n'ụdị ihe dị iche iche nke impregnating. Ka ihe atụ, phenolic impregnated graphite nwere ike idi 170-200 ℃, na ọ bụrụ na a kwesịrị ekwesị ego nke silicone resin impregnated graphite na-agbakwunyere, ọ nwere ike idi 350 ℃. Mgbe etinyere phosphoric acid na carbon na graphite, enwere ike imeziwanye nguzogide oxidation nke carbon na graphite, na enwere ike ịbawanye okpomọkụ nke arụ ọrụ n'ezie.
4, elu adịghị mfe nhazi. "Mmetụta" dị n'etiti flake graphite na ọtụtụ mgbasa ozi dị ntakịrị, ya mere unyi adịghị mfe ịrapara n'elu. A na-ejikarị eme ihe na akụrụngwa condensation na akụrụngwa crystallization.
Enwere ike ịhụ na akụrụngwa nwere graphite flake nwere ezigbo nguzogide corrosion na akụrụngwa anụ ahụ na akụrụngwa, enwere ike iji ya mepụta akụrụngwa mgbochi corrosion yana gbasaa na ụlọ ọrụ kemịkalụ.
