Ifayibha yekhabhoni yaziva
Intshayelelo
Ikhabhoni kunye neGraphite evakalayo yinto ethambekileyo ethambisa ubushushu obuguquliweyo obuqhelekileyo obusetyenziswa kwindawo yezitovu nakwimeko ekhuselekileyo yomoya ukuya kuthi ga kwi-5432 ℉ (3000 ℃). Ubunyulu obuphezulu obuziva ubushushu bubunyangwa ukuya kuma-4712 ℉ (2600 ℃) kunye noCoceko lweHalogen ziyafumaneka kwiiodolo zemveliso yesiqhelo. Ukongeza, izinto ezingasetyenziselwa kwiqondo lobushushu lobushushu ukuya kuthi ga kwi-752 ℉ (400 ℃).
Uhlobo lokwenza i-carbon fiber esebenze kakuhle luvakala kakhulu, amalaphu, iifilments, kunye nefayibha yemifuno (viscose fiber) okanye enye into yokwenza izinto zaselwandle njengezinto ezingafunekiyo, eziqale zaqulunqwa emva koko zenziwa yikhabhoni. Iiatom zekhabhoni zikho ngohlobo lokufakwa ngaphakathi kwe-microcrystals ezinje kwigaldi yecarbon. Uku-odolwa kwendawo enamacala amathathu akulunganga.
Olunye uphawu kukuba inendawo enkulu yomphezulu, kwaye inani elikhulu le micropores livulwe kumphezulu wefayibha. Kwinkqubo ye-adsorption kunye ne-desorption, indlela ye-adsorption imfutshane, kwaye i-adsorbent inokungena ngqo kwi-micropores.Okubonelela ngemibandela ye-adsorption ekhawulezayo ye-carbon fiber esebenzayo kunye nokusetyenziswa okusebenzayo kwemicroprop.
Indawo yendawo ethile yecarbon esebenze ngokukhawuleza inkulu, iipores ziphuhliswe kakuhle, ukusebenza kwe-adsorption kuphezulu, isantya senkqantosi sikhawuleza, sinokusetyenziswa okuphindaphindiweyo njalo njalo.
Yintoni umahluko phakathi kwePan neRayon Felts?
I-Polyacrylonitrile, ekwabizwa ngokuba yi-PAN, yenziwa ngeefayile zekhosi zobubanzi obukhulu obukhokelela kwindawo engezantsi komgangatho kunye nokuxhathisa okungcono kwe-oxidation. Izinto eziguqukayo ziyaqina kwaye zingaphantsi kancinane ekuchukumiseni xa kuthelekiswa neRayon. Ukuqhutywa kweshushu kweRayon kuphantsi kunePAN kumaqondo obushushu angaphezulu kwama-3272 ℉ (1800 ℃).
Malunga nezicelo zokunyanga ubushushu, iofisi yethu incoma kakhulu ikhabhoni ye-PAN evakalayo ngenxa yezinto eziphatha lula kunye nexabiso elincitshisiweyo. Ukuba usebenza kumaqondo obushushu angaphezu kwama-3272 ℉ (1800 ℃), nceda usebenzise iRayon.
IINZUZO
Kulula ukusika kwaye ufake.
Ukuxinana okuphantsi kunye nobunzima bokushisa.
Ukuxhathisa okuphezulu kweoli.
Umlotha ophantsi kunye nomxholo wesalfure.
Akukho kugxothwa.
Ukusetyenziswa
(1) Ukuvuselela i-solvent: i-benzene, ketone, ester, ioyile inokuvuselelwa kwe-adsorption.
(2) Ukucocwa komoya: kungathatha kwaye kuhlise umoya kwivumba, ivumba lomzimba, umsi, irhasi, i-O3, i-SO2, HAYI.
(3) Ukucocwa kwamanzi: kungasusa iioyile zentsimbi ezinobunzima emanzini, izinto ezinoburharha, ivumba, ukubumba, iintsholongwane kunye ne-decolorization; inokusetyenziselwa unyango lwamanzi empompo, amanzi eshishini lokutya kunye namanzi amdaka avela kwimizi-mveliso.
(4) ubunjineli bendalo esingqongileyo: irhasi yenkunkuma kunye nonyango lokuhambisa amanzi amdaka;
(5) Izixhobo zokuphefumla, iimpahla zokukhusela, iifilitha zecuba, njl .;
Ukukhutshwa kwesinyithi okuxabisekileyo okanye ukubuyiselwa kwimeko yesiqhelo, i-adsorption yezinto ezinokubakho kwiradiyo, inokusetyenziswa njengento ebambekayo yokuthwala, isigaba segesi se-chromatography esisigxina;
Unyango kwiphakeji, i-antidoteote acute, izintso zokufakelwa, njl .;
E. Izicelo ze-elektroniki nezamandla, ezinjengee-capacitors eziphezulu, iibhetri zokugcina, njl .;
Ubushushu obuphezulu kunye nezinto zokufakelwa.
I-fiber fiber esebenze ngokuhambelana nezinto inokuhlula-hlulwa ibe yi-viscose, i-polyacrylonitrile ezimbini zilandelelana, ngohlobo lwe:
● I-fiber fiber esebenze ngaphakathi ivakale
● I-carbon fiber esebenzeyo
