Otú ọ dị, ọ bụ ihe a na-apụghị ịgbagha agbagha ma e jiri ya tụnyere ihe ndị a kpara akpa, eriri carbon nwere àgwà dị mma nke ukwuu, na atụmanya ntinye ya n'ọdịnihu sara mbara.Nke a bụ otu n'ime ihe mere Benfa Technology mere mgbe carbon eriri akpa technology a isi itunanya direction.
E jiri ya tụnyere ihe ndị a kpara akpa, kedu ihe e ji mara ihe eji eriri carbon?
1. Ike ike siri ike
Ike ike nke eriri carbon dị ihe dị ka 2 ruo 7 GPa, na modul tensile bụ ihe dịka 200 ruo 700 GPa.Njupụta dị ihe dị ka gram 1.5 ruo 2.0 kwa cubic centimita, nke a na-ekpebikarị site na okpomọkụ nke usoro carbonization na mgbakwunye na nhazi nke silk mbụ.N'ozuzu mgbe elu okpomọkụ 3000 ℃ graphitization ọgwụgwọ, njupụta nwere ike iru 2.0 grams kwa cubic centimita.Tụkwasị na nke ahụ, ịdị arọ ya dị nnọọ mfe, ike ndọda ya dị mfe karịa aluminum, ihe na-erughị 1/4 nke ígwè, na ike ya kpọmkwem bụ okpukpu 20 nke ígwè.Ọnụ ọgụgụ mgbasawanye okpomọkụ nke eriri carbon dị iche na eriri ndị ọzọ, ọ nwekwara njirimara nke anisotropy.
2. Obere ọnụọgụ mgbasawanye thermal
Ọnụ ọgụgụ mgbasawanye ọkụ nke ọtụtụ eriri carbon n'onwe ya adịghị mma n'ime ụlọ (-0.5 ~ -1.6) × 10-6 / K, ọ bụ efu na 200-400 ℃, na 1.5 × 10-6 / K mgbe ọ na-erughị 1000 ℃. .Ngwakọta agwakọta nke emere na ya nwere ọnụọgụ mgbasawanye kwụsiri ike ma nwee ike iji ya dịka ngwa eji atụ atụ.
3. Ezi conductivity thermal
N'ozuzu, thermal conductivity nke inorganic na organic ihe adịghị mma, ma thermal conductivity nke carbon fiber dị nso na nke ígwè.N'iji uru nke a mee ihe, enwere ike iji ya mee ihe maka ndị na-anakọta okpomọkụ nke anyanwụ na ihe ọkụkụ na-ekpo ọkụ na-ekpo ọkụ na-ekpo ọkụ na-ekpo ọkụ na-ekpo ọkụ.
4. Dị nro na nhazi
Na mgbakwunye na njirimara nke ihe carbon n'ozuzu, eriri carbon fiber kpara akwa nwere ọmarịcha anisotropic dị nro n'ọdịdị na enwere ike ịhazi ya na akwa dị iche iche.N'ihi obere ike ndọda ha, ha na-egosipụta ike dị elu n'akụkụ eriri eriri.Ihe mgbanaka eriri carbon gbasiri ike na ihe mejupụtara resin oxygen nwere ihe ngosipụta kachasị elu nke ike akọwapụtara na modul dị iche iche n'etiti ihe arụrụ arụ dị ugbu a.
5. Obere okpomọkụ na-eguzogide
Carbon fiber nwere ezigbo nguzogide okpomọkụ dị ala, dịka ọ naghị emebi emebi n'okpuru mmiri mmiri nitrogen.
6. Nguzogide corrosion
Carbon fiber nwere ezigbo nguzogide corrosion na ihe mgbaze organic izugbe, acid na alkalis.Ọ naghị agbaze ma ọ bụ zaa.Ọ nwere nguzogide corrosion pụtara ìhè na ọ nweghị nsogbu nke nchara.
7. Ezigbo mgbochi iyi
A naghị ejikarị eriri carbon na ígwè eme ihe mgbe a na-ete ibe ha.A na-eji eriri carbon dochie asbestos iji mepụta ihe mgbakasị ọkwa dị elu, bụ nke ejirila dị ka ihe mgbochi breeki maka ụgbọ elu na ụgbọ ala.
8. Ezigbo elu okpomọkụ na-eguzogide
Arụmọrụ nke eriri carbon na-akwụsi ike n'okpuru 400 Celsius, na enweghị mgbanwe dị ukwuu ọbụlagodi na 1000 Celsius.Igwe ọkụ dị elu nke ihe ndị mejupụtara ihe mejupụtara na-adabere na nguzogide okpomọkụ nke matriks.Ogologo oge na-eguzogide okpomọkụ nke ihe ndị mejupụtara resin dabeere na ihe dị ka 300 ℃, na elu okpomọkụ na-eguzogide nke seramiiki dabeere, carbon dabeere na metal dabeere na ihe mejupụtara nwere ike dakọtara na carbon eriri n'onwe ya.A na-eji ihe mejupụtara eriri carbon fiber eme ihe n'ọtụtụ ebe na ụlọ ọrụ ikuku dị ka ihe na-eguzogide okpomọkụ dị elu.
9. Ezigbo mma
Carbon fiber nwere ezigbo mma (otu n'ime ihe nnọchianya nke ịdị mma bụ ọnụọgụ gram nke eriri ogologo mita 9000), n'ozuzu naanị ihe dị ka gram 19, yana ike ike ruru 300 kg kwa micron.Ole na ole ihe ndị ọzọ nwere ọtụtụ ihe mara mma dị ka eriri carbon.
10. Mmetụta mmetụta na-adịghị mma ma dị mfe imebi
Oxidation na-eme n'okpuru ọrụ nke acid siri ike, ike electromotive nke eriri carbon dị mma, na ike electromotive nke aluminum alloy adịghị mma.Mgbe a na-eji ihe ndị mejupụtara carbon fiber jikọtara ya na alloys aluminum, carbonization metal, carburization na electrochemical corrosion ga-eme.Ya mere, a ghaghị ịgwọ eriri carbon n'elu tupu ejiri ya.
