Txoj kev loj hlob ntawm cov khoom siv tsheb, feem ntau: tsis tshua tsw, thaj chaw yooj yim, tab sis kuj txo cov hom ntaub ntawv. Ntev iav fiber reinforced PP yog precisely vim hais tias ntawm qhov zoo saum toj no, lub gradual hloov ntawm luv iav fiber reinforced nylon nyob rau hauv lub tsheb. Niaj hnub no peb tuaj mus nkag siab lub ntev iav fiber reinforced polypropylene khoom tsim ntawm qhov nyuaj thiab ua kom pom tseeb;
Ntev iav fiber reinforced polypropylene cov ntaub ntawv nyob rau hauv lub tsheb yam tshawb fawb thiab daim ntawv thov, yog ib qho ntawm cov kub pob nyob rau hauv xyoo tsis ntev los. Ntev iav fiber reinforced polypropylene yas yog hais txog qhov ntev ntawm 10 mus rau 25 hli hauv iav fiber ntau hloov polypropylene puas khoom, tom qab kev txhaj tshuaj molding txheej txheem tsim ib lub qauv peb sab, lus Askiv Ntev iav Fiberpolypropylene , txhais ua LGFPP. Muaj kuj muaj ntau cov ntaub ntawv nyob rau hauv tsev thiab txawv teb chaws yuav ntev-fiber ntau dua thermoplastics uas hu ua LFT, Abbreviation ntawm ntev fiber reinforce thermoplastic. Ntawm cov khoom txhais, LGFPP belongs rau LFT.
Daim duab: Ntev iav fiber nrog rau qhov kawg ntawm iav fiber ntau sib piv
Cov khoom muaj nqi
Lub microstructure txiav txim xyuas cov kev ua lag luam, 10 ~ 25 hli ntev glass reinforced yas (LGFPP daim ntawv luv luv) muaj zog dua, nruj, muaj zog, Tsis tshua curvature thiab lwm yam zoo. Tsis tas li ntawd, ntev iav fiber ntau reinforced polypropylene tsis muaj qhov tseem ceeb hauv siab txawm nyob rau siab kub ntawm 100 ° C thiab muaj kev zoo tsis txaus siab tshaj li luv-iav-reinforced polypropylene.
Nyob rau hauv qhov kev txiav txim tiav, ntev iav fiber ntau hla mus rau hauv ib lub qauv ntawm peb lub voj voog, txawm tias cov polypropylene substrate hlawv, lub iav fiber ntau lub network tseem muaj qee cov teeb meem ntawm lub iav fiber ntau cev pob zeb, thiab cov iav fiber ntau tom qab hlawv tsis muaj zog pob txha. Yog vim li cas rau qhov no mas vim tias qhov sib piv ntawm qhov ntev ntawm lub zog ntawm cov khoom siv fwj tsuj txiav txim siab qhov kev siv zog txhawb nqa. Qhov tseem ceeb ntev = L / D, tus tub ntxhais uas muaj qhov ntev ntawm lub cev muaj zog ntawm tsawg dua 100 thiab luv iav fibers muaj tsis muaj zog, thiab qhov tseem ceeb ntev mus rau qhov sib piv yog tsawg dua 100 iav fiber ntau plays lub luag haujlwm.
Muab piv rau cov hlau thiab thermoset composites, cov iav ntev-fiber ntau muaj qhov tsawg tsawg thiab txo qhov hnyav ntawm tib seem ntawm 20 mus rau 50%. GF plastics muaj cov qauv tsim cov khoom yooj yim dua, xws li kev muaj peev xwm ua kom cov duab zoo nkauj, Cov khoom sib xyaw ua ke kom siv, txuag cov nqi pauv (feem ntau ntev iav yas txhaj mold raug nqi txog 20% , txo cov zog siv zog (ntev fiberglass yas ntau zog zog tsuas yog 60 ~ 80%, 35 ~ 50% ntawm cov khoom txhuas), simplifying lub rooj sib txoos txheej txheem.
Raws li cov ntaub ntawv zoo ntawm cov iav ntev fiber ntau cov ntaub ntawv, nws tau ua ntau dua thiab ntau dua siv nyob rau hauv kev siv tsheb. Peb tau pom ntau dua thiab ntau yam ntawm cov khoom siv hauv qab no uas siv cov iav ntev fiber ntau reinforced polypropylene, ntev fiber ntau reinforced polypropylene Siv rau lub tsheb dashboard cev pob txha, roj teeb bracket, front-end module, hwj huam tswj lub thawv, lub rooj txhawb pab, lub tsho yas, fender, chassis npog, lub suab sib, lub qhov rooj ntawm qhov rooj.
Khoom nyuaj nyuaj thiab ua kom pom tseeb
(1) Lub tswv yim ntawm EVI (Lub Tsheb Mus Nkag Mus): Cov khoom lag luam khoom ntiag tug, koom nrog tus qauv tshiab qauv thaum lub caij nyoog tsim kho, nkag siab txog OEM cov kev xav tau cov ntaub ntawv los txhim kho cov khoom hloov thiab cov kev hloov; Yog hais tias tsuas yog cov qauv tsheb khoom siv raws li cov ntaub ntawv xaiv, ces lub tsheb ua lag luam thiab lub caij tsheb ciav hlau muaj txog 5 xyoos xaiv cov khoom sib txawv.
(2) Cov Nqi Them Nqi (Cost Analysis): Yog tias tus nqi ntawm cov ntaub ntawv raw nkaus xwb, qhov nqi ntawm ib plhuav ntawm cov yas yog siab dua cov khoom siv hlau. Txawm li cas los xij, cov peev hauv cov nqi pwm tseem qis dua. Pwm yas txhaj tshuaj yog tsuas yog 50% ntawm cov hlau qhov pwm. Cov hlau pwm 30 ~ 40%; Integrated peripheral components, modular supply, koj tuaj yeem txuag tau tus nqi ntawm tus tswv tsev cog kev sib txoos, txo cov teeb meem los ua ke thiab txuag chaw.
(3) lwm yam: kev hloov hauv hom khoom siv hauv ntu, cov khoom hloov yuav tsum tsim cov pwm tshiab; tib lub sij hawm rau ntev iav tshwj xeeb cov ntaub ntawv, yuav tsum tau siv txawv los ntawm pa txhaj tshuaj molding cov cav tov thiab lwm cov khoom ua. Txawm hais tias, yog ib feem ntawm feem ntau ntawm cov kev pib siv los ntawm tus neeg muag khoom los lees, tab sis nyob hauv OEM yuav tsum ua ntev glass fiber ntau industrialization txheej txheem ntawm ntau yam teeb meem kev txhawj xeeb hauv cov lus teb.
