Chii chinonzi glass fiber reinforced plastic?
Girazi faibha yakasimbiswa mapurasitiki akasiyana siyana ezvakasanganiswa zvinhu zvine akasiyana zvivakwa uye yakafara application.Icho chinhu chitsva chinoshanda chakagadzirwa nesynthetic resin uyefiberglass inoumba zvinhu kuburikidza neyakaumbwa maitiro.
Hunhu hwegirazi fiber yakasimbiswa mapurasitiki:
(1）Yakanaka corrosion resistance: FRP chinhu chakanaka chisingadziviriri.Iine kupikisa kwakanaka kumhepo;mvura uye huwandu hwakawanda hweasidhi uye alkali;munyu, mafuta akasiyana-siyana uye zvinonyungudutsa, uye yakashandiswa zvakanyanya mumakemikari anti-corrosion.pamativi ose.Iri kutsiva kabhoni simbi;simbi isina ngura;huni;non-ferrous simbi nezvimwe zvinhu.
(2) Huremu huremu uye simba rakakwirira: Hukama hwehuwandu hweFRP huri pakati pe1.5 ne2.0, inongori 1/4 kusvika 1/5 yeiyo carbon simbi, asi simba rekusimba riri pedyo kana kutokwira kupfuura iro kabhoni. simbi, uye simba rinogona kufananidzwa nepamusoro-giredhi alloy simbi., anoshandiswa zvakanyanya mumhepo;midziyo ine simba guru uye zvimwe zvigadzirwa zvinoda kuderedza uremu hwavo.
(3) Mamiriro emagetsi akanaka: FRP chinhu chakanakisa chekudzivirira, chinoshandiswa kugadzira insulators, uye chinogona kuchengetedza kuita kwakanaka pamhepo huru.
(4) Kushanda kwakanaka kwekupisa: FRP ine yakaderera magetsi conductivity, 1.25 ~ 1.67KJ pakamuri tembiricha, chete 1/100 ~ 1/1000 yesimbi ndiyo yakanakisa yekupisa yekupisa zvinhu.Ideal for thermal protection uye ablation resistance pasi penguva pfupi yakanyanya kupisa mamiriro.
(5) Yakanakisa maitiro ekuita: maitiro ekuumba anogona kusarudzwa zvichienderana nechimiro chechigadzirwa, uye maitiro ari nyore uye anogona kuumbwa panguva imwe chete.
(6) Yakanaka dhizaini: zvinhu zvinogona kusarudzwa zvizere zvinoenderana nezvinodiwa kuti zvienderane nezvinodiwa zvechigadzirwa kuita uye chimiro.
(7) Low elastic modulus: Iyo elastic modulus yeFRP yakakura 2 nguva kupfuura iyo yehuni asi 10 nguva idiki pane iyo yesimbi, saka inowanzonzwa kuti kuomarara hakuna kukwana muchimiro chechigadzirwa uye nyore kuremara.Mushonga wacho unogona kuitwa muganda rakaonda;iyo sandwich chimiro chinogona zvakare kugadzirwa muchimiro chepamusoro modulus fiber kana kusimbisa mbabvu.
(8) Kusagadzikana kwenguva refu kwekudzivirira kwekushisa: Kazhinji, FRP haigoni kushandiswa kwenguva yakareba pakupisa kwepamusoro, uye simba reFRP re-general-purpose polyester resin richaderera zvakanyanya kana iri pamusoro pe50 degrees.
(9) Chiitiko chekuchembera: pasi pekuita kwemwaranzi ye ultraviolet;mhepo, jecha, mvura nechando;makemikari media;mechanical stress, nezvimwewo, zviri nyore kukonzera kuderera kwekuita.
(10) Low interlaminar shear simba: Iyo interlaminar shear simba inotakurwa neresin, saka yakaderera.Iyo interlayer adhesion inogona kuvandudzwa nekusarudza maitiro, uchishandisa coupling agent, nezvimwewo, uye edza kudzivirira interlayer kuveura panguva yekugadzirwa kwechigadzirwa.
Zvakanakira zvegirazi fiber yakasimbiswa mapurasitiki:
Iyo tembiricha inodzivirira kupisa kwegirazi fiber yakasimbiswa mapurasitiki yakakwira zvakanyanya kupfuura iyo isina girazi fiber, kunyanya naironi plastiki.
Girazi fiber yakasimbiswa mapurasitiki ane yakaderera shrinkage uye yakakwirira rigidity.
Iyo girazi faibha yakasimbiswa epurasitiki haitsigire kutsemuka, uye kukanganisa kupikisa kwefemoglas fibra de vidrio plastiki inovandudzwa zvakanyanya
Simba regirazi fiber yakasimbiswa mapurasitiki akakwira, senge: kusimba simba, kumanikidza simba, kubhenda simba, zvese zvakakwirira kwazvo.
Nekuda kwekuwedzera kwezvimwe zvinowedzera,fiber glasmapurasitiki akasimbiswa akadzikisa zvakanyanya kupisa kwegirazi fiber reinforced mapurasitiki, uye zvinhu zvakawanda hazvigone kudzima, saka chinhu chinodzoreredza moto.
Kuipa kwegirazi fiber yakasimbiswa mapurasitiki:
Nekuda kwekuwedzera kweuye glassfiber, iyo girazi faibha yakasimbiswa plastiki yave opaque, uye inoonekera isati yawedzera girazi fiber.
Ipurasitiki yegirazi fiber yakasimbiswa plastiki ine kuoma kwakaderera uye kuwedzera brittleness kupfuura plastiki isina girazi fiber;
Nekuda kwekuwedzera kwegirazi fiber, iyo yakanyunguduka viscosity yezvinhu zvese inowedzera, iyo fluidity inova isina kunaka, uye jekiseni rinomanikidza rakakwira zvakanyanya kupfuura iro risina girazi fiber.Kune yakajairika jekiseni kuumbwa, tembiricha yejekiseni yeese akasimbiswa mapurasitiki akakwira kupfuura iwo pasina kuwedzera girazi fiber.Iyo girazi fiber yakambosimudzwa ne10 ℃-30 ℃.
Nekuda kwekuwedzera kwegirazi fiber uye zvinowedzera, iyo hygroscopic maitiro edaw fiberglass mapurasitiki akasimbiswa anowedzerwa zvakanyanya.Iwo mapurasitiki akachena epakutanga asingatore mvura anozonyurawo.Naizvozvo, dzinofanirwa kuomeswa panguva yekuumba jekiseni.
Munguva yekuumbwa kwejekiseni regirazi fiber yakasimbiswa epurasitiki, iyo girazi fiber inogona kupinda pamusoro pechigadzirwa chepurasitiki, ichiita kuti pamusoro pechigadzirwa kuve kushata uye nemavara.Kuti uwane yepamusoro yepamusoro mhando, mold tembiricha muchina unoshandiswa kupisa mold panguva yekugadzira jekiseni, kuitira kuti epurasitiki polymer ipinde pamusoro pechigadzirwa, asi kutaridzika kwemhando yepurasitiki yakachena haigone kuwanikwa.
Mushure mekunge girazi fiber yakasimbiswa,e girazi fiberglass chinhu chine kuoma kwepamusoro.Mushure mekunge iyo yekuwedzera yanyungudutswa pakupisa kwakanyanya, igasi rinotyisa kwazvo, rinokonzera kupera kukuru uye kukora kune screw uye jekiseni mold yemuchina wekuumba jekiseni.Nokudaro, rudzi urwu rwezvinhu runoshandiswa mukugadzira.Paunenge uchishandisa mold uye majekiseni ekuumba michina, teerera kune epamusoro anti-corrosion kurapwa uye kuoma kwepamusoro kurapwa kwemidziyo.
Kusimbisa mhedzisiro yegirazi fiber pane nylon
Nylon, inozivikanwawo se polyamide, chinhu chekugadzira chine huwandu hwakasiyana hwemashandisirwo, ayo anoshandiswa mumachira, kurongedza, mekiniki zvikamu uye mamwe minda.
Sepurasitiki yeinjiniya, PA66 ine huwandu hukuru hwemapoka e-hydrophilic amide, ayo anodzikamisa ndima yayo yekushandisa.Iyo inowanzoshandiswa muindasitiri kuigadzirisa nenzira ye copolymerization, kusanganisa kuomesa, uye kusimbisa.
Girazi faibha reinforcement inowanzoshandiswa kushandura nzira.Inogona kunyatso kusimudzira kupfeka kuramba, simba, kuomarara uye dimensional kugadzikana kwenylon.
Girazi faibha inogadzirwa nepyrophyllite, jecha requartz, limestone uye mamwe mamineral kuburikidza nekupisa tembiricha, kudhirowa waya, mhepo, kuruka uye mamwe maitiro, uye dhayamita yemonofilament ingangoita mamicrons mashoma.
Nheyo yegirazi fiber reinforcement: Kune nzira nhatu dzekuti faibha itore simba rekukanganisa: kutsemuka kwefiber, kudhonza kwefiber, uye kuputsika kweresin.Kana hurefu hwefiber hunowedzera, iyo fiber inodhonza kunze inoshandisa simba rakawanda, iro rinobatsira mukuvandudzika kwesimba rekukanganisa.
PA66/girazi fiber composite material ine yakaderera mvura yekunyura, yakakwirira chaiyo simba uye makemikari kuramba, uye zvigadzirwa zvayo zvine hunyoro hwekunyura, kugadzikana kwedimensional, kusimba kwepamusoro, kuoma, uye kugadzirisa kuita, saka inoshandiswa zvakanyanya munjanji, muchina, mota. , midziyo yemagetsi nemimwe minda.
Kureba kwezvinhu elastic modulus fiber giraziinowanzoshandiswa kusimbisa naironi inenge 3mm kusvika 12mm.Sezvo hurefu hwefiber hunowedzera, mhedzisiro yekusimbisa zvinhu inowedzera.Yakanaka kutenderera 12mm.
Kazhinji, kureba kwefiberglass filamentiri 12mm, uye kureba kweakachekwa girazi fiberiri 3mm.Kuenzaniswa nepfupi girazi faibha, iyo inoshamisa chimiro cherefu girazi fiber reinforcement ndechekuti simba rekuita rakapetwa kaviri.Uye zvakare, refu girazi faibha yakasimbiswa naironi composites ine zvakanakira simba rakakwirira, kusimba kwepamusoro, yakakwirira nottched simba rekuita, kupfupika kwekupisa kupisa uye kwakanaka kuneta kuramba, uye inogona kuramba ichichengetedza yakanaka mechanical zvivakwa mukupisa kwakanyanya uye yakakwirira humidity nharaunda., iyo inogona kushandiswa sechinhu chekugadzirisa panzvimbo yesimbi.
