Daim ntawv thov thiab kev txhim kho kev taw qhia ntawm cov khoom siv yas rau cov tsheb tshiab zog

Tam sim no, nyob rau hauv lub ntiaj teb no txoj kev loj hlob tseem ceeb ntawm kev hais txog "ob chav carbon" lub tswv yim, txuag, ntsuab thiab recycling tau dhau los ua txoj kev loj hlob ntawm cov khoom siv tsheb tshiab thiab cov thev naus laus zis tshiab, thiab lub teeb yuag, cov ntaub ntawv ntsuab thiab cov khoom siv rov ua dua tshiab tau dhau los ua txoj kev loj hlob tseem ceeb ntawm tsheb tshiab. cov ntaub ntawv. Tsav los ntawm nthwv dej ntawm tsheb sib tsoo, cov ntaub ntawv yas tau dhau los siv dav hauv kev tsheb vim tias lawv qhov hnyav txo qis. Txawm hais tias nws yog cov khoom siv kho kom zoo nkauj sab nrauv ntawm lub tsheb, cov khoom siv kho kom zoo nkauj sab hauv xws li cov cuab yeej ntsuas vaj huam sib luag, lub qhov rooj vaj huam sib luag, cov cuab yeej siv hluav taws xob, lub hnab looj tes npog, lub rooj zaum, lub rooj zaum hauv qab phaj, lossis cov khoom siv thiab cov qauv tsim, koj tuaj yeem pom cov duab ntxoov ntxoo ntawm cov yas nyob txhua qhov chaw. Tshwj xeeb tshaj yog tam sim no, lub zog tshiab tsheb tau dhau los ua lub ntsiab lus ntawm kev hloov pauv thiab kev loj hlob ntawm kev lag luam tsheb thoob ntiaj teb. Lub teeb yuag ntawm lub zog tshiab tsheb yog ceev tshaj li cov tsheb tsoos. Daim ntawv thov ntawm cov ntaub ntawv yas tau nthuav dav rau lub zog tshiab lub tsheb roj teeb lub plhaub thiab lwm yam khoom siv. Nyob rau tib lub sijhawm, cov nplaim hluav taws kub hnyiab, kev tiv thaiv ib puag ncig siab, khawb tsis kam, siab gloss, corrosion tsis kam thiab lwm yam kev ua haujlwm ntawm automotive plastics kuj muab cov kev cov nyom ntau dua.

Kev siv ntau yam ntaub ntawv yas feem ntau siv hauv tsheb

PA

Polyamide PA feem ntau hu ua Nylon. Cov khoom siv zoo heev, tensile, compressive thiab hnav tsis kam. PA6, PA66, txhim kho nplaim taws retardant PA6 yog siv nyob rau hauv tsheb cav thiab cav peripheral qhov chaw, cav cover, cav trim cover, lub tog raj kheej taub hau cover, roj lim, wiper, radiator grille, thiab lwm yam.

PAB 66

PA66 tau txais los ntawm polycondensation ntawm adipic acid thiab hexandiamine ntawm molar piv ntawm 1: 1. Adipic acid feem ntau yog tsim los ntawm hydrogenation ntawm ntshiab benzene thiab oxidation nrog nitric acid. PA66 tseem tuaj yeem tswj tau lub zog muaj zog thiab nruj ntawm qhov kub siab dua; PA66 muaj lub zog zoo txhua yam, zoo kev ntxhov siab tawg ua haujlwm, thiab yog qhov zoo tshaj plaws hnav tsis kam nylon; PA66 tus kheej lubricating zoo heev, thib ob tsuas yog PTFE thiab polyformaldehyde; PA66 muaj cov khoom siv thermal zoo thiab yog cov khoom siv tua tus kheej, tab sis nws cov dej nqus tau loj, yog li nws qhov kev ruaj ntseg tsis zoo.

PA6+ GF30

PA6 GF30 yog qhov tshwm sim ntawm kev hloov kho ntawm PA6. PA6 GF30 txhim kho cov khoom siv los ntawm kev ntxiv iav fibers. Cov iav fiber ntau nws tus kheej muaj cua sov ua haujlwm, nplaim taws ua haujlwm, tiv thaiv corrosion, rwb thaiv tsev kub, siab tensile zog thiab zoo hluav taws xob rwb thaiv tsev. Tom qab ntxiv dag zog los ntawm iav fiber ntau, PA6 GF30 cov khoom tuaj yeem ua tau raws li qhov yuav tsum tau muaj ntawm kev lag luam thiab kev siv txhua hnub, thiab muaj cov yam ntxwv ntawm lub zog zoo, ua haujlwm kub, tiv thaiv kev tiv thaiv thiab kev ruaj ntseg.

PMMA + ASA

PMMA, feem ntau hu ua "plexiglass". Nws muaj lub teeb xa hluav taws xob zoo, cov khoom siv kho tshuab thiab kev laus ua haujlwm zoo thiab huab cua tsis kam. Tab sis nws cov brittleness yog siab, yooj yim rau tawg, cuam tshuam tsis zoo.

ASA, zoo li hauv cov qauv rau ABS, siv cov roj hmab acrylic tsis muaj ob daim ntawv cog lus es tsis txhob siv roj hmab butadiene hauv ABS. Nws muaj qhov ua tau zoo heev, huab cua tsis zoo, thiab zoo dua rau cov tshuaj corrosion. Tab sis nws cov tawv hardness tsis siab, khawb kuj, hnav tsis kam yog tsis zoo.

ABS

ABS yog acrylonitrile - butadiene - styrene copolymer, nws yog ntau yam thermoplastic engineering yas, nws cov kev cuam tshuam tsis kam, kub tsis kam, tsis kub tsis kam, tshuaj tiv thaiv thiab cov khoom siv hluav taws xob zoo heev, tab sis kuj muaj kev ua haujlwm yooj yim thiab cov khoom lag luam zoo, ruaj khov, gloss, Feem ntau yog siv rau tsheb cua txias tuyere, hloov, ntsuas qhov chaw nyob ib puag ncig, khov tiv thaiv phaj, qhov rooj kov, Bracket, log npog, reflector vaj tse, fender kev nyab xeeb kov, thiab lwm yam.

PC / ABS alloy

PC / ABS (P acrylonitrile - butadiene - styrene copolymer alloy): qhov zoo ntawm PC yog tawv thiab tawv, qhov tsis zoo yog kev ntxhov siab tawg, viscosity; Qhov zoo ntawm ABS yog fluidity zoo, tab sis tsis tshua muaj deg hardness; Ua li no, cov khoom sib xyaw P / ABS khaws qhov zoo ntawm ob qho tib si; PC / ABS muaj qhov tawv tawv, siab rigidity thiab toughness, thiab kev ntxhov siab tawg tsis kam; Nws mechanical zog yog qhov chaw nyob nruab nrab ntawm. PC/ABS alloy nyob rau hauv lub tsheb dashboard, qhov rooj kov, bracket, steering kem sheath, hniav phaj, cua txias system accessories, tsheb log cover, reflector plhaub, tail lampshade thiab ntau lwm qhov chaw yog siv.

Kev txhim kho yav tom ntej ntawm automotive plastics

Kev xav tau ntawm cov neeg siv khoom ntau ntxiv rau kev siv roj-npaum, ruaj khov thiab lub teeb yuag tsheb yuav txhawb kev xav tau ntawm cov yas hauv kev lag luam tsheb. Ntawm cov yas siv hauv tsheb, kev siv cov khoom siv dav dav (xws li PP, PE, PVC, ABS, thiab lwm yam) suav txog li 60%, thaum kev siv cov yas yas (xws li PA, PC, PBT, thiab lwm yam. .) suav txog li 18%. Yog li ntawd, rau cov tsheb niaj hnub, txawm hais tias nws yog kev kho kom zoo nkauj sab hauv, kho kom zoo nkauj sab nrauv, lossis cov qauv kev ua haujlwm ntawm lub tsheb, feem ntau ntawm cov khoom tau pib siv cov khoom yas es tsis txhob siv cov hlau, uas yog, cov khoom siv hluav taws xob ntawm "yas hloov. ntawm steel" trend prevailing.
