Yuav ua li cas LFT-PP Chaw Nyob Thermal Runaway thiab Qhov hnyav hauv pob roj teeb

Yuav ua li cas LFT Composites daws roj teeb Enclosure Thermal Runaway

Lub 2026 roj teeb exhibition lub caij, suav nrog CIBF Shenzhen thiab Lub Roj Teeb Qhia Tebchaws Europe hauv Stuttgart, ua pov thawj tias cov khoom siv roj teeb yog qhov tseem ceeb tsim kev xav. Cov tsoos aluminium enclosures ntsib teeb meem pom tseeb: kev kub ceev ceev thaum lub sij hawm thermal runaway, ntxiv rwb thaiv tsev yuav tsum tau, thiab ib tug 35-45 kg nce nyob rau hauv pob qhov hnyav uas txo EV tsav ntau yam.

Ntev fiber reinforced thermoplastics, tshwj xeeb tshaj yog LFT-G^®PP, tab tom tshwm sim los ua ib qho kev npaj tsim khoom.

Thermal runaway: muaj qhov xwm txheej

Thaum lub cell nkag mus rau hauv thermal khiav, qhov kub thiab txias tuaj yeem nce siab tshaj 800℃hauv vib nas this. Aluminium, nrog rau thermal conductivity nyob ib ncig ntawm 200 W / m·K, ua raws li lub tshav kub kis tau tus mob - zoo hloov lub zog mus rau cov hlwb uas nyob ib sab thiab ua rau muaj kev pheej hmoo ntawm cascading tsis ua hauj lwm.

LFT-PP ua haujlwm ntawm lub hauv paus ntsiab lus sib txawv. Nws cov matrix thermal conductivity yog kwv yees li 0.3 W / m·K, ntau tshaj li ob qhov kev txiav txim siab qis dua aluminium. Thaum raug nplaim taws, nplaim taws-retardant LFT-G^®PP-LGF qib sai tsim cov txheej ntom ntom ntom ntom ntom ntom ntom. Qhov no char, kaw nyob rau hauv qhov chaw los ntawm cov iav fiber ntau ntev, insulates cov khoom siv hauv qab thiab ua rau cov cua sov nkag mus sai heev - yuav lub sij hawm muaj nuj nqis ntxiv kom ncua sij hawm ntawm cell-to-cell propagation thaum lub sij hawm thermal runaway tshwm sim. Peb LFT-G^®PP LGF nplaim hluav taws-retardant qib ua tiav UL94 V-0 kev faib tawm thaum khaws cov txheej txheem pob txha uas ntev fiber ntau muab. Rau cov neeg tsim qauv, lub thawv ntim tau dhau los ua ib qho thermal barrier uas pab kom muaj qhov xwm txheej, es tsis yog cov khoom siv hluav taws xob uas ua rau nws nrawm dua.

Chemical resistance thiab dimensional stability

Nyob rau hauv ib lub pob, cov kuab tshuaj electrolyte thiab cov kua dej txias ua rau muaj kev kub ntxhov hauv ib puag ncig. Aluminium yuav tsum tau coatings los tiv thaiv corrosion, thiab txhua qhov khawb yuav ua tsis tiav. Polypropylene yog inherently resistant rau acids, alkalis, thiab carbonate solvents - tsis xav tau txheej.

Mechanically, lub roj teeb enclosure nyob rau hauv tas li vibration thiab thermal cycling. Cov fibers luv luv nkag mus, ua rau bolt torque poob thiab kaw qhov khoob. LFT-G^® PP-LGF tshem tawm qhov no los ntawm nws sab hauv3D fiber ntau pob txha, txo cov kab nrib pleb los ntawm qhov kev txiav txim siab piv rau luv fiber ntau PP. Nws cov coefficient ntawm thermal expansion tuaj yeem raug kho kom haum rau txhuas, khaws cia kev ruaj ntseg ntawm lub tsheb lub neej.

Lightweighting thiab ib feem consolidation

Ib lub lauj kaub hlau hnyav hnyav 60-80 kg. Aluminium txo qhov no rau 35-45 kg. Ib qho ntxivtxhaj tshuaj molded LFT-PPenclosure hnyav 25-35 kg - txo 30-50% piv rau txhuas thiab tshaj 80% piv rau hlau.

Qhov tseem ceeb tshaj, LFT-G^®PP-LGF ua kom muaj kev sib koom ua ke. Cov cua txias raws, mounting bosses, ribbing, cable clips, thiab sensor brackets tuaj yeem molded ncaj qha rau hauv lub tais. Dab tsi yog ib zaug sib dhos ntawm 20-30 cov khoom siv hlau thiab cov sealants ua ib qho molding nrog ib lub rooj vag zoo. Rau high-volume platforms, cov kab sib dhos yooj yim feem ntau tshaj qhov sib txawv ntawm cov khoom siv raw khoom.

Regulatory npaj thiab recyclability

Txoj Cai EU Roj Teeb yuav tsum tau tshaj tawm cov pa roj carbon hneev taw los ntawm 2027 mus ntxiv, nrog cov ntsiab lus rov ua dua tshiab kom nruj mus txog xyoo 2030. Cov khoom siv txhuas rov ua dua tshiab yog lub zog txuag, tab sis thawj cov khoom lag luam muaj cov pa roj carbon ntau (12-16 kg CO₂ ib kg).

LFT-G^®cov khoom siv: ib txoj kev sib txawv: thaum kawg ntawm lub neej, lub thawv tuaj yeem rov ua dua tshiab. Thermoplastic matrix yog remeltable, thiab huv, high-purity nkauj xwb formulation ntawm peb LFT-G^®cov ntaub ntawv kom paub tseeb tias recyclate zoo.

Qhov twg LFT-PP haum rau koj tus qauv tsim

Ib txoj haujlwm uas yuav tsum tau txo qis dua 30% ntawm txhuas, yuav tsum dhau UL94 V-0 ntawm qhov chaw kaw, ntsib cov hluav taws xob ntev ntev, thiab tuaj yeem tau txais txiaj ntsig los ntawm kev sib sau ua ke ntau qhov chaw rau hauv ib qho molding - xws li ib qhov project yuav tsum ntsuas LFT-PP los ntawm lub tswv yim theem. Rau kev txhim kho platform tshiab, rooj plaub ntawm kev ua tau zoo yog qhov nyuaj ntxiv kom tsis quav ntsej.

NtawmXiamen LFT, peb LFT-G^®PP series yog tsim rau cov qauv siv roj teeb uas yuav tsum tau muaj cov nplaim hluav taws kub hnyiab thiab tshuaj lom neeg. Peb muab cov pwm khiav simulation kev txhawb nqa, FEA cov ntaub ntawv cov ntaub ntawv, thiab cov qauv pellets rau kev sim pwm hauv tsev.
