PP raws li ib yam ntawm cov ntaub ntawv yas, nrog kev ua zoo tag nrho kev ua tau zoo, ruaj ntseg tshuaj stability, zoo molding kev ua tau zoo thiab tus nqi qis; tab sis muaj PP zog, modulus, tsawg hardness, feem cuam tshuam tsis tshua muaj neeg pluag, ua Shrinkage, yooj yim laus thiab lwm yam shortcomings.
Feem ntau, PP khoom tensile lub zog ntawm 20M ~ 30MPa, bending zog ntawm 25M ~ 50MPa, flexural modulus ntawm 800M ~ 1500MPa. Yog li ntawd, nws yog hloov kho thiaj li hais tias nws yuav yoog tau rau cov kev xav tau ntawm cov khoom. Niaj hnub no, txhua daim PP hloov tau ntau daim ntawv sau npe ntawm thaj chaw siv khoom siv hluav taws xob thiab kev siv tsheb.
Ntev iav Fibre
GF (iav los yog fiberglass) yog ib hom kev kawm zoo heev uas tsis muaj cov khoom siv hlau, qhov zoo tshaj yog qhov rai zoo, ua kom tsis muaj zog, ua kom tsis muaj zog, ua kom muaj zog, tab sis qhov tsis zoo yog qhov tsis muaj zog, tsis ua hauj lwm hnyav. Ib qho ntawm cov kev siv loj ntawm iav fiber reinforced cov ntaub ntawv rau cov ntaub ntawv puas. Ntev iav ntev feem ntau yog hais txog qhov ntev ntawm ntau tshaj 10mm iav fiber ntau.
Ntev iav fiber reinforced PP yas
Ntev iav fiber reinforced PP yas hais txog qhov ntev ntawm 10 mus rau 25mm iav fiber ntau hloov cov ntaub ntawv PP, tom qab txhaj tshuaj molding txheej txheem tsim lub iav fiber ntau dua 3.1 hli 3-dimensional, lus Askiv LongGlassFiberpolypropylene, muab txhais ua LGFPP. Muaj ntau cov ntaub ntawv nyob hauv tsev thiab txawv teb chaws yuav ntev-fiber ntau dua thermoplastics uas hu ua LFT (Long-fiberreformetermoplastic). Ntawm cov khoom txhais, LGFPP belongs rau LFT.
Raws li lub tsheb sib tw khoom khoom siv, cov ntaub ntawv no tuaj yeem tsis tsuas yog ua kom txhim kho txoj kev tsis sib haum, kev ua haujlwm tsis zoo, kev tsis sib haum thiab kev ruaj ntseg ntawm cov khoom, tab sis kuj tuaj yeem ua rau cov khoom muag nyuaj.
Ntev iav fiber reinforced PP particle morphology
Feem ntau 12 hli lossis 25 hli ntawm qhov ntev, hais txog 3 hli ntawm txoj kab taub sab. Txog 12 lub hli ntawm qhov ntev ntawm cov pellet yog siv rau kev txhaj tshuaj molding, thiab txog 25 hli ntev ntawm cov pellet yog siv rau kev sib tsoo molding. Nyob rau hauv cov khoom siv no, iav fiber muaj qhov ntev tib yam li cov khoom siv, cov ntsiab lus ntawm cov iav fiber ntau ntawm 20% mus rau 70%, thiab cov xim ntawm cov particle yuav ua raws li qhov kom ua ntawm tus neeg tuaj.
Yog vim li cas Ford lub tuam txhab nrog cov iav ntev fiber ntau reinforced PP, ntau dua iav fiber reinforced PP?
Hais rau cov iav fibers ua haujlwm zoo hauv cov yas kom muaj zog, qhov ntev ntawm cov iav fibers yuav tsum tau ua ntau dua lawv cov ntev Lo tseem ceeb. Cov ntaub ntawv qhia tau tias thaum qhov ntev ntawm fiber ntau tsawg dua qhov ntev ntawm lub fiber ntau reinforced yas nyob rau ib qho load, lub fiber yuav tsum tau tawm, fais fab tuag tsis tau siv tag nrho. Qhov tseem ceeb ntev, Lo, yog muaj feem xyuam rau cov kev muaj ntau hom, thiab rau lub iav siv hluav taws xob reinforced polypropylene, Lo yog 3.1 hli.
Qhov no qhia tau hais tias hom tsis ua hauj lwm yog qhov fiber ntau yog rub tawm thiab tsis tuaj yeem ua raws li qhov kev xav tau ntawm cov khoom siv hauv cov khoom sib chaws. Yog li ntawd, txoj kev loj hlob thiab kev siv ntawm ntev iav fiber reinforced polypropylene thiab nws cov tshuaj molding tshuab, yog npaj los txhim khu qhov ntev ntawm iav fiber ntau txog 10 lub hli ntawm polypropylene raw khoom, thiab los ntawm kev txhim kho kev txhaj tshuaj molding txheej txheem los xyuas kom meej tias cov khoom nyob rau hauv cov iav fiber ntev 3.1 hli saum toj no.
Qhov zoo ntawm LFT vs. Luv Fiber Muaj zog Thermoplastic Composites:
• Ntev ntev ntev, txhawm rau txhim kho cov cuab yeej hluav taws xob.
• Kev siab tawv thiab lub zog muaj zog, kev ua haujlwm zoo dua, tshwj xeeb tshaj yog rau cov ntawv siv tsheb.
• Txhim kho cov neeg tsis haum, kev ruaj ntseg zoo thiab qhov siab ua qhov tseeb.
Kev qaug zog zoo heev.
• Muaj kev ruaj ntseg zoo nyob rau hauv qhov kub thiab txias.
• Thaum lub sijhawm ua tus txheej txheem, cov fibers yuav txav ib leeg rau ib leeg rau hauv cov txheej txheem pwm, uas ua kom tsis muaj fiber ntau.
