Amaphuzu asemqoka:
· Amandla asheshayo kanye ne-tensile modulus ye-carbon fiber composite acishe abe ngu-50% ngaphezulu kune-T300;
· Ama-glass fiber composites angahlangabezana nezidingo zokuklama ze-dielectric ephansi njalo futhi zinciphise izindleko zokukhiqiza;
· Izingxenye zepulasitiki ze-fluorine zingasiza izindiza ezinkulu zokushisa okuphezulu nokuphikisana nokugqwala;
Izinto ezibonakalayo zezinyosi ze-Aramid zingafinyelela isisindo esikhanyayo namandla aphezulu;
· Okokuqala, i-aromatic sulfone fiber yayisetshenziswa ngaphakathi kwekhabethe le-C919 ukwenza izembozo ezihlalweni namakhethini emnyango, onciphise isisindo sezindiza ngamakhilogremu angaphezu kwama-30.
Ukundiza kokuqala kwezentengiso kwendiza enkulu yeChina C219 kuphumelele. Ukusuka eShanghai kuya eBeijing, kusuka eShanghai kuya eChengdu, ukufika kahle kaninginingi kusho ukuthi indiza enkulu yasekhaya yangena ngokusemthethweni imakethe yezindiza zomphakathi, ivule uhambo olusha lokusebenza okuqondiswe emakethe kanye nentuthuko yezimboni!
I-C919 iqede ngempumelelo indiza yayo yokuqala yezentengiso. (Isikweletu sesithombe: Abantu.com.cn)
Izindiza ezinkulu zabagibeli ziyinkimbinkimbi imikhiqizo eyinkimbinkimbi kakhulu nenezobuchwepheshe emhlabeni namuhla. Njengenye yezinto ezibalulekile ukusiza izindiza ezinkulu zifinyelele ekhasini elingasindi, ilangabi elishintshiwe, izinga lokushisa eliphakeme nokugqwala, yiziphi izingxenye ze-C 919 zibonisa amakhono azo ngalesi sikhathi?
1. I-T800 Carbon fiber composite impahla
Njengamanje, isigaba esingemuva se-C919 Resear Feender Fuselage, umsila osindayo, umsila omile, i-lieling, i-readder, ama-flaps, ama-ailerons, ama-winglet, i-apobile kanye nezinye izingxenye zisebenzisa izinto ze-carbon fiber composite.
Izinto ze-carbon fiber composite ezisetshenzisiwe ikakhulukazi ibanga le-T800. Ikwamukela i-matrix eqinile ye-epoxy resin, i-fiber eqinisiwe yi-T800 carbon fiber, amandla ashubile kanye ne-modululus tensile ephakeme kungama-50% aphezulu kune-T300, futhi nakho okusetshenziswa kakhulu kwe-composite air faild ethriza isakhiwo.
Izinsiza ze-2.Glass fiber composite
Uma kuqhathaniswa ne-Carbon fiber Composites, izakhiwo zemishini ze-fiber fiber aphansi kancane, kepha ngenxa ye-dielectric ephezulu ehlala i-carbon fiber, kuzothinta umsebenzi omkhulu we-radar, futhi i-radome yendiza enkulu yabagibeli ye-C919 isebenzisa izinhlanganisela ze-glass fiber.
Ezinye izingxenye ezinengcindezi encane, njengezithoshi, nazo zisebenzisa ama-composites e-fiberglass. Ngoba izindleko zezinto zokwenziwa ze-fiber fiber eziphansi kunalezo ze-carbon fiber composite izinto zokwakha, ukusetshenziswa kwezakhi ezincane zamandla kungahlangabezana nezidingo zokuklama futhi kunciphise izindleko.
3.Fluorine imikhiqizo yepulasitiki
Imikhiqizo yepulasitiki ye-Fluorine enikezwe yi-GERUI New Material. (Photo kusuka ku-Gerui New Material)
Imikhiqizo ye-Aviation Fluoroplastic njengenye yezingxenye ezijwayelekile ezingezona zensimbi ezisetshenziswa endizeni enkulu, impahla yayo eluhlaza yi-polytetrafluoroethylene, okungukuthi, "inkosi edumile".
Lezi zingxenye ezijwayelekile ezikhiqizwe yi-polytetrafluoroethyleneeneneneneenereneneneevenies eziphakeme kakhulu njengokumelana nezinga lokushisa eliphakeme, ukumelana nokugqwala, ukufakwa kukagesi, njll. Imikhiqizo isetshenziselwa ikakhulukazi ukulungisa nokuxhuma izintambo eziyinkimbinkimbi zezindiza nezintambo ezindizeni.
I-Zhejiang Gerui New Materics Co, Ltd. (Kubizwa ngokuthi "izinto ezintsha zeGerui") zilethe izigaba eziyisishiyagalombili zemikhiqizo yendiza enkulu yasekhaya C919, futhi indiza ngayinye enkulu ye-C919 isebenzisa imikhiqizo engaphezu kuka-10,000 yokulekelela izindiza.
I-4.Aramid yezinyosi zezinyosi
The doors of the C919 large passenger aircraft and the floor of the passenger and cargo compartment are made of aramid honeycomb material, a lightweight, high-strength non-metallic bionic core material made of phenolic resin impregnated aramid paper. Kulingisa ukwakheka kwezinyosi zezinyosi, kunesakhiwo esizinzile, esingasindi futhi namandla aphezulu, kunamandla aphezulu okugula ngokuqhathaniswa nezinto ezibalulekile ze-foam, futhi kuvinjezelwe kakhulu ukugqwala uma kuqhathaniswa noju lwezinyosi.
Ngasikhathi sinye, impahla ye-ARAMID yezinyosi nayo inobunzima obuphezulu, ukumelana nokukhathala okuhle nokumelana nomlilo, futhi kuyinto ekahle yezindiza ezibonakalayo ezinhlamba.
I-5.aromatic sulfone fiber
Ikhabethe le-C919 okokuqala ukusebenzisa i-aromatic sulfone fiber ukwenza ikhava yesihlalo, ikhethini lomnyango, lizokwenza ukuncishiswa kwesisindo sendiza kwamakhilogremu angaphezu kwama-30, indiza ngayinye ingagcina izindleko ezingaphezu kuka-10,000.
I-Aromatic Sulfone Fibre ibizwa nge-PSA Fiber, eyakhiwa nge-polysulfone antide. Izici zalo eziphambili zingukufakelwa kahle kukagesi nokumelana nokushisa. Ngaphezu kwalokho, i-flame retardant ephezulu, okukhawulelwe inkomba-oxygen ye-30%, ukuqina okuhle kwamakhemikhali. Ngaphezu kwama-sol sol sollents ambalwa kakhulu kanye ne-sulfuric acid egxilile, kunokuqina okuhle kumakhemikhali wokushisa kwegumbi.
I-Aromatic Sulfone Fibre ayikwazi ukwenza kuphela izinto zokuhlunga eziphakeme zokungamelana nezinga lokushisa nokushisa okuphezulu kanye nezinto zokwakha ama-voltage kagesi aphezulu, kepha futhi zingacutshungulwa zibe yizindwangu ze-flame retardant ezithuthukile ezimotweni zokuhamba.
6.Rubber Compound
Amathayi endiza enziwe ngezinto ezifanayo njengamathayi emoto, kepha umehluko omkhulu ukuthi amathayi endiza asebenzisa amakhilogremu aphezulu we-intshi yengcindezi yomoya, kanti amathayi endiza angakhuphuka amathanga amathayi emoto, futhi i-C919 isebenzisa amathayi e-radial avela eMichelin.
I-Yihhoo Polymer ngumhlinzeki womhlaba wonke wezithasiselo zokuguqulwa kwamapulasitiki kanye nezimbobo, kufaka phakathi ama-antionings, ama-antioilividants, ama-flame atatiliving kanye ne-racitiven retadadants, esetshenziswa kakhulu esifundeni sase-Asia-Pacific.
