Ntev iav fiber reinforced polypropylene yas hais txog kev hloov kho polypropylene cov khoom siv nrog cov iav fiber ntau ntev ntawm 10-25mm, uas yog tsim rau hauv peb-seem qauv los ntawm kev txhaj tshuaj molding thiab lwm yam txheej txheem, abbreviated li LGFPP.Vim nws txoj kev ua tau zoo heev, ntev iav fiber ntau reinforced polypropylene yog ntau thiab ntau dav siv nyob rau hauv automotive teb.
Cov yam ntxwv thiab qhov zoo ntawm cov iav fiber ntau reinforced polypropylene
- Zoo dimension stability
- Kev qaug zog zoo heev
- Me me creep kev ua tau zoo
- Me anisotropy, tsawg warpage deformation
- Cov khoom siv kho tshuab zoo heev, tshwj xeeb tshaj yog cuam tshuam
- Zoo fluidity, haum rau nyias-walled khoom ua
10 ~ 25mm ntev iav fiber reinforced polypropylene (LGFPP) muaj zog dua, nruj, toughness, seem stability, thiab tsawg warpage piv rau zoo tib yam 4 ~ 7 hli luv iav fiber reinforced polypropylene (GFPP).Tsis tas li ntawd, ntev iav fiber reinforced polypropylene cov ntaub ntawv yuav tsis tsim creep tseem ceeb txawm tias nws yuav raug kub siab ntawm 100 ℃, thiab nws muaj kev nkag tau zoo dua li cov iav fiber ntau reinforced polypropylene.
Nyob rau hauv cov khoom txhaj tshuaj molded, cov iav ntev fibers yog staggered rau hauv peb-dimensional network qauv.Txawm hais tias tom qab polypropylene substrate raug hlawv, lub iav fiber ntau ntev tseem tsim cov iav fiber ntau lub cev nrog lub zog, thaum lub iav fiber ntau luv luv feem ntau dhau los ua cov fiber ntau tsis muaj zog tom qab hlawv.cev pob txha.Qhov teeb meem no yog tshwm sim los vim qhov ntev-rau-ntev piv ntawm cov fiber reinforcing txiav txim siab cov nyhuv reinforcing.Fillers thiab luv iav fibers nrog qhov tseem ceeb piv txwv tsawg dua 100 tsis muaj qhov txhawb ntxiv, thaum cov iav iav ntev nrog qhov sib piv tseem ceeb tshaj 100 ua lub luag haujlwm ntxiv.
Piv nrog cov ntaub ntawv hlau thiab cov khoom siv thermosetting sib xyaw, cov iav fiber ntau yas ntev muaj qhov ntom ntom, thiab qhov hnyav ntawm tib qhov tuaj yeem raug txo los ntawm 20% mus rau 50%.Ntev iav fiber ntau yas tuaj yeem muab cov neeg tsim qauv tsim kom yooj yim dua, xws li cov duab moldable nrog cov duab nyuaj.Tus naj npawb ntawm cov khoom siv thiab cov khoom siv sib xyaw ua ke txuag cov nqi pwm (feem ntau, tus nqi ntawm cov iav fiber ntau yas txhaj tshuaj pwm yog kwv yees li 20% ntawm tus nqi ntawm cov hlau stamping pwm), thiab txo cov kev siv hluav taws xob (kev siv hluav taws xob ntau ntawm cov iav fiber ntau ntev. tsuas yog 60% ntawm cov khoom steel.
Daim ntawv thov ntev iav Fiber Reinforced Polypropylene hauv Tsheb Qhov Chaw
Ntev-fiber reinforced polypropylene yog siv nyob rau hauv lub tsheb dashboard lub cev ncej, roj teeb bracket, pem hauv ntej-kawg module, tswj lub thawv, lub rooj txhawb nqa ncej, spare placenta, mudguard, chassis cover, suab nrov barrier, rear qhov rooj ncej, thiab lwm yam.
Pem hauv ntej-kawg modules: Rau automotive pem hauv ntej-kawg modules, siv LGFPP (LGF cov ntsiab lus 30%), nws muaj peev xwm integrate ntau tshaj 10 tsoos hlau qhov chaw xws li radiators, hais lus, condensers, thiab brackets rau tag nrho;nws yog corrosion-resistant ntau dua li hlau qhov chaw.Qhov ceev yog me me, qhov hnyav yog txo los ntawm 30%, thiab nws muaj ntau dua ntawm kev tsim kev ywj pheej.Nws tuaj yeem siv ncaj qha yam tsis muaj kev txheeb xyuas thiab ua tiav;nws txo cov nqi tsim khoom thiab muaj cov txiaj ntsig zoo hauv kev txo nqi.
Cov cuab yeej vaj huam sib luag lub cev pob txha: Rau cov khoom siv hluav taws xob zoo nkauj, siv cov khoom siv LGFPP muaj zog dua, siab dua dabtsi yog khoov modulus, thiab fluidity zoo dua li cov ntaub ntawv PP.Nyob rau hauv tib lub zog, lub thickness ntawm qhov ntsuas vaj huam sib luag tsim yuav raug txo kom txo tau qhov hnyav, qhov hnyav hnyav hnyav yog li ntawm 20%.Nyob rau tib lub sij hawm, cov tsoos multi-component ntsuas vaj huam sib luag bracket tuaj yeem tsim rau hauv ib qho module.Tsis tas li ntawd, cov khoom xaiv ntawm lub hauv ntej defrosting duct lub cev thiab nruab nrab thav duab ntawm lub dashboard feem ntau yog tib yam khoom raws li lub ntsiab ncej ntawm lub dashboard, uas muaj peev xwm ntxiv txhim kho qhov hnyav txo.
Lub rooj zaum rov qab: Nws tuaj yeem hloov cov txheej txheem steel ib txwm ua kom txo tau qhov hnyav ntawm 20%, thiab muaj kev ywj pheej tsim kev ywj pheej thiab kev ua haujlwm zoo, thiab cov yam ntxwv xws li nthuav qhov chaw zaum.
Daim ntawv thov tseem ceeb ntawm cov iav ntev fiber ntau reinforced polypropylene hauv automotive teb
Nyob rau hauv cov nqe lus ntawm kev hloov cov khoom siv, ntev iav fiber reinforced polypropylene cov khoom tuaj yeem txo qhov hnyav thiab tus nqi tib lub sijhawm.Yav dhau los, luv iav fiber reinforced cov ntaub ntawv hloov cov ntaub ntawv hlau.Nyob rau hauv xyoo tas los no, nrog rau daim ntawv thov thiab kev loj hlob ntawm lub teeb yuag, ntev iav fiber reinforced polypropylene cov ntaub ntawv tau maj mam hloov luv luv iav fiber reinforced yas nyob rau hauv ntau thiab ntau lub tsheb qhov chaw, uas yog ntxiv txhawb nqa.Kev tshawb fawb thiab kev siv cov ntaub ntawv LGFPP hauv tsheb.
