Automotive cav npog yog qhov tseem ceeb heev nyob ntawm lub cav tsheb thiab yog qhov tseem ceeb uas yuav tsum tau tsav tsheb kom zoo.
Audi, Dongfeng, Geely cav npog xaiv Xwb
Vim tias lub cev nyhav thiab kev nyab xeeb, cov tuam txhab loj tshaj plaws hauv lub ntiaj teb no tau txais txoj kev los tsim cov cav tsheb uas yog npog yas hlau, thiab tau tsim kom muaj cua sov, kev tiv thaiv kom ntev ntev thiab cov roj ua haujlwm ntawm cov khoom yas Cov qauv uas yuav tsum tau ua. Xws li Audi tsheb nrog high mobility nylon A1G6-HR kho, Dongfeng cav hau nrog ntev iav fiber reinforced PP khoom LGF-P1G6HM, Geely tsheb engine npog nrog pob zeb hauv av enhanced PP khoom P1M8R-W01.
Yog li ntawd, los ntawm kev nkag siab tob txog kev ua lag luam, cov neeg sib txawv nyias muaj nyias cov kev cai sib txawv rau cov kev sib txawv ntawm cov khoom siv. Qhov no yuav tsum tau ceev faj txog cov khoom siv hauv kev ua haujlwm ntawm lub cav tsheb npog thiab txawv ntawm cov khoom siv rau kev hloov tsheb txawv, Kev xaiv lub hau kuj txawv dua. Tam sim no, muaj ntau yam peb hom khob fiber ntau zog dua PA, ntev iav fiber reinforced PP thiab pob zeb ua kom muaj zog dua PP.
Rooj ntawv 1 txawv cov qauv ntawm qhov kev zov me nyuam
Ua ntej, PA + GF nyob rau hauv lub hood npog daim ntawv thov
PAJ + GF yog ib qho zoo tshaj plaws rau cov kev lag luam siab muaj lub tshuab npog npog xaiv. PA + GF muaj zoo heev ua hauj, kev laus ua hauj lwm thiab kev kho khoom zoo, kev ruaj ntseg stability, haus dej cawv thiab ua kom tsis muaj zog, tab sis tsis muaj zog, txhaj molding nyuaj. Thiaj li yuav ua kom nws cov qeeb qeeb, nws yuav tsum muab hloov.
Xws li: Cov tsheb uas siv hauv Audi siv rau hauv A1G6-HR, muaj kev khiav zoo thiab cov khoom siv dag zog, muaj zog nce txog ze li ntawm 60%, kom luv phom ntawm 15% -30%, thiab qhov sib, tuab ntawm ntau dua Txog 20%.

Lub cav hoods muaj qhov siab xav tau ntawm cov khoom siv thermal cov khoom siv rau cov khoom, thiab cov ntaub ntawv siv hauv lub hau hood npog yuav tsum yog muaj feem xyuam mus rau lub sij hawm ntev thermal qhov chaw ua haujlwm.
Lub ntsuas thermal aging ntawm PA6-GF30 ntawm 2500C rau 2500 teev tom qab qhia tau hais tias lub zog tensile retention ntawm cov PA6-GF30 yog tshaj 80% thiab qhov ua rau qis dua qhov qub qis dua 65%, ob leeg muaj kev zoo Thermal laus zog. Yog li, PA-30GF khoom tsim rau lub hood.
Qhov ob, tsab ntawv thov hloov polypropylene hauv lub tsho
Rau qhov chaw pib khoom siv, kev siv cov nylon hloov txhais tau hais tias ntau dua moulding kub thiab ntev moulding yuav tsum tau tsim cav npog uas ua tau raws li qhov yuav tsum tau muaj. Yog li ntawd, nws yog ib qho kev xav tau ntau tshaj plaws nyob rau hauv kev lag luam kom tau lub tsheb tsheb npog cov ntaub ntawv uas muaj nqi ntau dua.
Tsis ntev los no, ntev cov iav fiber reinforced PP cov ntaub ntawv tseem pheej yig thiab muaj qhov kev ua haujlwm zoo tib yam li engineering plastics, yog li ua tau qhia cov txiaj ntsim ntawm cov nuj nqis siab. Cov khoom siv LFT-PP yog hais txog kev hloov PP uas muaj cov iav fibers uas ntev ntev txog 10 mus rau 25 hli, uas tuaj yeem ua rau txhim kho txoj kev quab yuam, qhov zog ntawm lub cev, kev tsis sib haum xeeb thiab kev ruaj ntseg ntawm qhov khoom.

Xam 2 hloov LFT-PP cov sib txuam thiab kev sib tshuam hauv seem
Ntev iav Fiber Muaj zog Polypropylene Composites muaj cov yeeb yam nram qab no:
Cov khoom lag luam zoo zoo, zoo heev tshuav ntawm rigidity thiab toughness;
Tsawg shrinkage, zoo heev stability tshaj ib qhov chaw kub dav thiab cov kab mob kev nyuab siab, kev ruaj siab siab;
High thais feem cuam tshuam zog;
Qhov sib npaug ntawm hlau thermal expansion coefficient;
Yav tav kev tsis zoo rau kev mob nkeeg
Nyob rau tib lub iav fiber ntau li, cov khoom siv ntawm cov iav Fiber Reinforced Polypropylene Composites zoo ib yam li cov khoom PA-GF, thiab nws cov qauv cim qhia tau hais tias cov khoom siv zoo heev. Tsis tas li, ntev iav fiber reinforced PP iav fiber reinforced PA6 khoom muaj cov nram qab no zoo:
Ntev 2 Ntev Iav Fiber Muaj zog Siv Polypropylene Composites thiab iav fiber reinforced PA kev sib piv
PA6-GF30
Yog li ntawd, Ntev iav Fiber Reinforced Polypropylene Composites tsis siv GF-PA siv rau hauv lub tshuab cov khoom khawm, nrog rau cov nqi zoo thiab cov txheej txheem zoo. Piv txwv, lub cav Dongfeng tam sim no npog nrog LGF-P1G6HM cov khoom no, 30% ntev fiber reinforced polypropylene , siab khiav, siab rigidity, high toughness, los tiv thaiv kev laus.
Thib peb, qhov hloov kho pob zeb txhim kho kom zoo dua qub nyob rau hauv ib qho kev xa me me cav xa mus rau daim ntawv zeem muag
Kev xaav me xaav kuas txav cov khoom kws yuav tsum tau ua, cov ntaubntawv rua kev hloov pauv loj, kws ua rua cov xuabmoos xaav nyob rua qhov qis dua, cov kev ua rua cov khoom tseem ceeb kuj raug txo. Qhov no coj tau cov sijhawm rau daim ntawv thov cov ntaub ntawv thaij duab PP. Rau txoj kev ua lag luam no, cov ntaub ntawv tshwj xeeb ntxhia muaj zog dua PP, xws li P1M8R-W01, muaj cov qauv ntawm 4000 MPa ntawm qhov chaw sov thiab nyob ruaj khov thaum muaj kev kub ntxhov.
0.45MPa kev ntsuam xyuas, cov kub kub qhov teeb meem kub txog 126 ℃, nrog rau cov cua kub zoo heev, ntxiv rau qhov kev xeem ntawv ntawm lub hau khwb yuav txo cov nqi. Cov khoom no yog ib qho kev hloov zoo rau cov nylon thiab yuav qhib ib lub lag luam tshiab rau cov khoom siv ua hluav taws xob-kho kom zoo dua PP-hloov mus rau lub cav daim ntawv thov kev siv peripheral thiab hloov cov khoom siv hlau.

Txawv tus neeg khoom cov khoom muab tso, kev ua haujlwm ntawm cov ntaub ntawv sib txawv. Yog li, kev xaiv PA + GF, los yog hloov kho Lub Ntev Ntoo Cov Fiber Ntau Fais Reinforced Polypropylene Composites los yog cov pob zeb ua kom zoo dua qub, raws li qhov kev xav tau ntawm cov tuam txhab sib txawv. Txawm li cas los, hloov ib co nylon nrog PP hloov nyob rau hauv ib co ntawm lub tsheb kawg sab yog qhov zoo los txo nqi.
