Vim li cas Ford siv cov iav fiber ntau ntxiv PP es tsis yog iav fiber ntau ntxiv PP?
Nyob rau hauv xyoo tas los no, ntev iav fiber ntau hloov PP tau kub heev nyob rau hauv kev hloov kho plastics kev lag luam. Cov iav ntev fiber ntau ntxiv PP cov khoom yog tus nqi qis thiab muaj kev ua tau zoo tshaj plaws hauv kev txhim kho cov yas yas. Kev sib xyaw ua ke ntawm ob qhov zoo ntawm kev siv nyiaj tau zoo tau pom dav los ntawm kev lag luam. Tam sim no, cov tuam txhab no tau nqis peev ntau ntawm cov neeg ua haujlwm thiab cov khoom siv rau kev tsim cov R & D thiab kev lag luam kev lag luam ntawm cov khoom siv no.
Ntev iav fiber ntau hloov PP yog dab tsi? Peb kawm step by step:
PP khoom
PP yog ib qho ntawm cov khoom siv yas, muaj kev ua tau zoo heev, kev ruaj ntseg tshuaj zoo, zoo molding processability thiab tus nqi qis; tab sis PP muaj zog, modulus, tsis tshua muaj hardness, tsis zoo ua hauj lwm rau qhov kub thiab txias, molding loj shrinkage, laus thiab lwm yam shortcomings.
Feem ntau hais lus, lub zog tensile ntawm PP cov khoom yog nruab nrab ntawm 20 ~ 30MPa, lub zog dabtsi yog khoov ntawm 25 ~ 50MPa, thiab flexural modulus yog nruab nrab ntawm 800 ~ 1500MPa. Yog li ntawd, nws tau hloov kho kom nws tuaj yeem hloov kho raws li qhov xav tau ntawm cov khoom. Niaj hnub no, txhua yam kev hloov kho PP muaj ntau daim ntawv thov hauv cov khoom siv hauv tsev thiab tsheb.
Ntev iav fiber ntau
Cov iav fiber ntau (Lus Askiv lub npe: iav fiber ntau lossis fiberglass) yog cov khoom siv tsis muaj hlau tsis muaj hlau nrog kev ua haujlwm zoo. Nws qhov zoo yog rwb thaiv tsev zoo, kub kub tsis kam, zoo corrosion kuj, thiab siab mechanical zog, tab sis nws qhov tsis zoo yog brittleness thiab kuj. Kev sib tsoo tsis zoo. Ib qho tseem ceeb ntawm kev siv iav fiber ntau yog cov khoom siv ntxiv ntawm cov ntaub ntawv sib xyaw. Ntev iav fiber feem ntau yog hais txog iav fiber ntau nrog qhov ntev ntawm ntau tshaj 10mm.
Ntev iav fiber reinforced PP yas
Ntev-iav-txhim kho PP yas hais txog kev hloov kho PP sib xyaw nrog iav fiber ntau ntev ntawm 10 mus rau 25 hli. Tom qab txhaj tshuaj molding, peb-seem qauv nrog lub iav fiber ntau ntev tshaj 3.1 hli yog tsim. Nyob rau hauv lus Askiv, Ntev iav Fiberpolypropylene yog abbreviated li LGFPP. Muaj ntau cov ntaub ntawv nyob rau hauv tsev thiab txawv teb chaws uas ntev fiber reinforced thermoplastics yog hu ua LFT (Long-fiber reinforced yas thermoplastic). Los ntawm cov ntaub ntawv txhais, LGFPP yog ib hom LFT.
Raws li lub tsheb module cov khoom siv, cov khoom siv tsis yog tsuas yog tuaj yeem txhim kho qhov rigidity, cuam tshuam lub zog, nkag siab thiab ruaj khov ntawm cov khoom, tab sis kuj tuaj yeem ua rau cov khoom lag luam nyuaj.
Ntev iav fiber reinforced PP particle morphology
Nws yog feem ntau cylindrical hais nrog ib tug ntev ntawm 12 hli los yog 25 hli thiab ib txoj kab uas hla ntawm txog 3 hli. Ntawm lawv, pellets nrog qhov ntev li ntawm 12 hli yog siv rau kev txhaj tshuaj molding, thiab pellets nrog qhov ntev li ntawm 25 hli feem ntau yog siv rau compression molding. Nyob rau hauv cov khoom no, cov iav fiber ntau muaj qhov ntev tib yam li cov khoom, thiab cov ntsiab lus ntawm cov iav fiber ntau tuaj yeem muaj li ntawm 20 feem pua rau 70 feem pua. Cov xim ntawm cov khoom tuaj yeem sib phim raws li tus neeg siv khoom xav tau.
Vim li cas Ford siv cov iav fiber ntau ntxiv PP es tsis yog iav fiber ntau ntxiv PP?
Txhawm rau kom cov iav fiber ntau ua haujlwm zoo hauv cov yas kom muaj zog, nws yog ib qho tsim nyog yuav tsum ua kom cov iav fiber ntau ntev dua nws qhov tseem ceeb ntev Lo. Cov ntaub ntawv tseem ceeb qhia tau hais tias thaum lub fiber ntau cov yas uas muaj fiber ntau tsawg dua qhov ntev tseem ceeb no tau raug rau ib qho kev thauj khoom, cov fiber ntau tau rub tawm thiab lub zog ntawm cov fiber ntau tsis tuaj yeem ua tiav. Qhov tseem ceeb ntev Lo muaj feem xyuam rau cov yas tshwj xeeb. Rau iav fiber reinforced polypropylene, Lo yog 3.1 hli.
Qhov no qhia tau hais tias hom tsis ua hauj lwm feem ntau yog vim tias cov fibers tau rub tawm thiab tsis tuaj yeem ua tau raws li qhov yuav tsum tau muaj zog ntawm cov khoom siv thauj khoom. Yog li ntawd, kev txhim kho thiab siv cov fiberglass ntev-txhim kho polypropylene thiab nws cov kev txhaj tshuaj molding tshuab yuav tsum tau npaj cov khoom siv polypropylene fiber ntau nrog cov iav fiber ntau ntev li ntawm 10 hli, thiab txhim kho cov txheej txheem txhaj tshuaj molding kom ntseeg tau tias cov iav fiber ntau ntev nyob rau hauv. cov khoom yog 3.1 hli. saum toj no.
Qhov zoo ntawm LFT dhau luv fiber reinforced thermoplastic composites:
• Ntev ntev fiber ntau ho txhim kho cov khoom siv ntawm cov khoom.
• Cov tawv nqaij tshwj xeeb thiab lub zog tshwj xeeb, muaj kev cuam tshuam zoo, thiab tshwj xeeb tshaj yog haum rau cov khoom siv hauv tsheb.
• Txhim kho creep tsis kam, zoo seem stability, thiab siab ua kom raug.
• Kev qaug zog zoo heev.
• Kev ruaj ntseg zoo dua hauv qhov chaw kub thiab av noo.
• Thaum lub sij hawm molding txheej txheem, cov fibers tuaj yeem txav mus rau ib leeg hauv kev tsim pwm thiab cov fibers puas me me.
