Ukuzizwa kwe-Carbon fiber
Isingeniso
I-Carbon ne-Graphite kuzwakala njengokufudumele okufudumele okushisa okuphezulu okujwayelekile okusetshenziselwa ukuvama nokuvikela umkhathi ezindaweni ezifika ku-5432 ℉ (3000 ℃). Ukuhlanzeka okuphezulu kuzizwe kuphathwa ukushisa kufinyelela kuma-4712 ℉ (2600 ℃) kanye nokuhlanzwa kweHalogen kuyatholakala kuma-oda wokwenza ngokwezifiso. Ngaphezu kwalokho, okusetshenziswayo kungasetjenziswa emazingeni okushisa we-oxid kuze kufike kuma-752 ℉ (400 ℃).
Uhlobo lokwenza i-carbon fiber ocushiwe luzwakale ikakhulu, indwangu, amakhemikhali, nefreyimu yemifino (i-viscose fiber) noma enye i-polymer enobuthi njengezinto zokusetshenziswa, kuqala yakhiwa bese kulandela ukwenziwa kwekhabhoni. Into esemqoka yikhabhoni. Ama-athomu wekhabhoni akhona ngohlobo lokufakwa okungahleliwe kwama-microcrystals ama-graphite-ku-fiber ocushiwe. Ukuhleleka kwesikhala esinezinhlangothi ezintathu akulungile.
Okunye okubonakalayo ukuthi inendawo enkulu ephezulu yendawo, futhi isibalo esikhulu sama-micropores ayavulwa ebusweni be-fiber. Ngenqubo ye-adsorption ne-desorption, indlela ye-adsorption imfushane, futhi i-adsorbent ingangena ngqo kwi-micropores.Lokhu kunikela ngemibandela ye-adsorption esheshayo ye-carbon fiber esebenzayo kanye nokusetshenziswa ngempumelelo kwama-micropores.
Indawo ethize engaphansi kwekhabhoni esebenze kahle inkulu, ama-pores athuthukiswe kahle, ukusebenza kwe-adsorption kuphezulu, ijubane le-desorption lishesha, lingasetshenziswa kaninginingi nokunye.
Uyini umehluko phakathi kwePan & Rayon Felts?
I-Polyacrylonitrile, eyaziwa nangokuthi i-PAN, yenziwa ngemicu emikhulu yenkambo yobubanzi obangela indawo ephansi nendawo nokumelana okungcono kwe-oxidation. Indwangu eguquguqukayo ilukhuni futhi ithambile kancane ekuthinteni uma uyiqhathanisa neRayon. Ukushiswa kokushisayo kweRayon kuphansi kunePAN emazingeni okushisa angaphezu kuka-3272 ℉ (1800 ℃).
Ngezicelo zokwelapha ukushisa, ihhovisi lethu litusa kakhulu i-PAN kaboni izwakala ngenxa yokusebenzisa izinto kalula kanye nentengo encishisiwe. Uma usebenza emazingeni okushisa angaphezu kuka-3272 ℉ (1800 ℃), sicela usebenzise iRayon.
IZINZUZO
Kulula ukusika nokufaka.
Ubuncane obuphansi kanye nesisindo esishisayo.
Ukumelana okuphezulu kokushisa.
Okuqukethwe komlotha ophansi nesibabule.
Akukho kudlula.
Ukusebenza
(1) Ukuvuselelwa kwe-solvent: i-benzene, i-ketone, i-ester, i-oyela kungaba ukuvuselelwa kwe-adsorption.
(2) Ukuhlanzwa komoya: kungathatha futhi kuhlunge umoya ngephunga, iphunga lomzimba, intuthu, igesi, i-O3, i-SO2, CHA.
(3) Ukuhlanzwa kwamanzi: kungasusa i-ion eningi yensimbi emanzini, izinto ezi-carcinogenic, iphunga, isikhunta, amagciwane kanye ne-decolorization; Kungasetshenziswa ekwelapheni amanzi kampompi, amanzi embonini yokudla namanzi amsulwa ezimboni.
(4) ubunjiniyela bezemvelo: igesi yokungcola kanye nokukhuculwa kwendle;
(5) Iziphefumula, okokuvikela okokuvikela, izihlungi zikagwayi, njll;
Ukukhishwa kwensimbi okuyigugu noma ukuthola kabusha, i-adsorption yezinto ezinemisebe, nakho futhi kungasetshenziswa njengesithwali sethonya, isigaba segesi se-chromatography esinqunyelwe
Umuthi on the package, antidote acute, izinso zokufakelwa, njll;
E. Izisetshenziswa ze-elekthronikhi nezamandla, njengama-capacitor aphezulu, amabhethri wesitoreji, njll;
Izinga lokushisa eliphakeme nezinto zokufakelwa.
I-fiber fiber esetshenzisiwe ngokwendwangu ingahlukaniswa nge-viscose, i-polyacrylonitrile uchungechunge ezimbili, ngokwesimo se:
● ocushiwe we-carbon fiber wazizwa ● ocishwe nge-carbon fiber Indwangu
● ocushiwe we-carbon fiber ● iphepha le-carbon fiber eliqalisiwe
