Carbon fiberndiye mumiriri wezvigadzirwa zvepamusoro-soro panguva ino.Chikonzero ndechekuti kabhoni fiber zvinhu zvine simba rakanaka kwazvo.Mumashandisirwo anoshanda, mukana wekureruka ndeyekuti kabhoni fiber zvinhu zvinogona kutsiva zvechinyakare zvigadzirwa zvesimbi.Zvakanakira kureruka kwechigadzirwa, mune dzimwe nzvimbo dzakakosha, kune zvakare zvakakwirira zvinodikanwa zvekuramba kwecorrosion yechinhu, saka iyo kabhoni fiber corrosion inodzivirira here?Ichi chinyorwa chichatevera mupepeti kuti atarise.
Iyo corrosion resistance yecarbon fiber yakakwira zvakanyanya.Izvi zvinodaro nekuti kugadzikana kwechimiro chefiber yakaputsika kune zvakawanda zvekuita nazvo.Kugadzirwa kwekabhoni fiber zvinhu zvinoda kunatswa pasi pezviuru zveC kubvisa tsvina yemukati uye kabhoni zvinhu.Iyo nzira ye lithification inoumba kabhoni microcrystalline chimiro.Ichi chimiro chenyama chine mukana wepamusoro wepakati corrosion resistance.Munharaunda ye50% hydrochloric acid kana sulfuric acid phosphoric acid, iyo yese mechanical properties inofananidzwa zvakadzama.Kusanganisira dhayamita yemakumbo haizoshanduki zvakanyanya, izvo zvinounzawo mabhenefiti akanaka ekuita kukudzivirira kwekukukurwa kweiyo fiber zvinhu.Izvi zvinovimbisa kuti kabhoni fiber inoratidza mukana wakanaka kwazvo mukupokana nekuora.
Zvinogona kuoneka kuti kabhoni faibha ine yakakwira corrosion resistance performance.Asi nokudacarbon fiberzvigadzirwa, izvi hazvisi izvo hazvo, nekuti yakachena fiber haigone kugadzirwa yakazvimirira kuita kabhoni fiber zvigadzirwa.Kana ichida matrix zvinhu, iyo yakajairika ndeye resin matrix zvinhu, uye corrosion kuramba yekabhoni fiber zvigadzirwa zvakangofanana neiyo resin.Iyo matrix pachayo uye yekusangana kwepamusoro pakati peresin uye kabhoni fiber zvakare ine zvakawanda zvekuita nayo.
Naizvozvo, kuita kweizvicarbon fiberchigadzirwa chakasiyana zvakanyanya kubva kune iyo resin matrix, uye ichavawo nekuita kwakasiyana munzvimbo dzakasiyana nenzvimbo dzakasiyana dzekushandisa.Semuyenzaniso, zvakajairika resin-based carbon fiber zvigadzirwa zvine yakanaka kwazvo corrosion resistance performance, uye inogona kuita yakanaka corrosion resistance performance munzvimbo dzakasiyana siyana, uye kuramba kwekunze kwemamiriro ekunze kwakanaka, asi kana kuri munzvimbo inopisa uye ine hunyoro hwemamiriro ekunze, zvichienzaniswa. kunharaunda yemukati menyika, ichakura nekukurumidza.Kusanganisira kushandiswa kwezuva nezuva kwezvigadzirwa zvekabhoni fiber, pasi pemwaranzi yezuva uye nekushandiswa kwakadzama kwemwaranzi yeultraviolet, ngura inowanzotanga kubva pamusoro pekuora.Kana isu tichigadzira zvigadzirwa zvelongtan fiber, kuitira kuti tive nechokwadi chekugara kweCorrosion kuramba, kazhinji zvinoreva kuti nzvimbo yacho inobatwa nemafuta uye yakaputirwa nependi inoonekera, iyo inogona kuve nechokwadi chekudzivirira kwekugara kwekabhoni fiber zvigadzirwa.
Kuti uve nechokwadi chekudzivirira kwekuora kwezvigadzirwa zvefiber, huwandu hwezvinhu zvematrix kazhinji kusarudza resin ine macromolecular zvimiro zvine zvimiro zvemuviri, benzene mhete, uye heterocycles, uye hydrogen shuga crystalline polymers inogona kuumbwa pakati pemamorekuru.Iyo matrix isarudzo yakanaka yekusimudzira corrosion kuramba yecarbon fiber composite zvigadzirwa.Mumashandisirwo anoshanda, iyo interface pakati peresin uye kabhoni fiber zvakare ipfungwa yakakosha inokanganisa corrosion, saka kupfekedzwa kwekabhoni fiber zvigadzirwa zvinogonawo kuvandudza zvinobudirira kuramba uye kudzivirira kupindira kwehunyoro kana inokuvadza midhiya.
Uye zvakare, panguva yekugadzirwa kwekabhoni fiber zvigadzirwa, isu tinoteererawo kune porosity yavo kana kukanganiswa kwechimiro, kusanganisira compaction kurapwa, iyo inogona kuita kuti kupinda kwezvinhu zvekuora kusanganise kupararira, inova zvakare yakakosha kurapwa kune vagadziri vedu kuvandudza corrosion resistance ye carbon fiber zvigadzirwa.Way.
Pakazara, iyo corrosion resistance yecarbon fiberyakanaka kwazvo.Ndobva ndati iyo yakazara corrosion kuramba yezvigadzirwa zvefiber ine hukama nehwaro zvinhu zvinosanganisira iyo chaiyo yekugadzira uye kugadzirisa maitiro.Kana paine zvinodikanwa zvekupikiswa kwecorrosion kwekabhoni fiber zvigadzirwa, Izvo zvinodikanwa kuti uwane emhando yepamusoro kabhoni fiber chigadzirwa vanogadzira, kuitira kuti ive nechokwadi chekuchengetedza corrosion zvinodiwa zvekabhoni fiber zvigadzirwa.
