Automotive sab nrauv qhov chaw yog cov khoom siv uas siv cov ntaub ntawv yas tshaj plaws hauv tsheb. Cov khoom siv sab nrauv feem ntau suav nrog cov yas yas xws li PP (polypropylene), ABS, ASA, POM (polyoxymethylene), PA (nylon), PC (polycarbonate), thiab PE (polyethylene) thiab lawv cov khoom sib xyaw. Kev xaiv cov khoom sib txawv nyob ntawm seb cov khoom tshwj xeeb.
Automotive bumper systems muaj xws li pem hauv ntej thiab rear bumpers. Cov ntaub ntawv siv hauv cov hnab yas feem ntau poob rau hauv ob pawg: polyester thiab polypropylene, thiab cov txheej txheem molding feem ntau yog txhaj tshuaj molding. Cov pa hluav taws xob feem ntau siv cov khoom siv xws li PC / ABS, electroplated PC / ABS, ASA, electroplated ABS, AES, thiab cua sov- tiv taus ABS. Cov iav sab nrauv sab nrauv tuaj yeem siv cov ntaub ntawv xws li cua sov- tiv taus ABS, PC/ABS, ASA, thiab PBT+GF. Pillar trim panels feem ntau siv cov ntaub ntawv xws li PC/ABS, ASA, M-PMMA, thiab AES. Sab tiab raug pom zoo kom siv PP + Mineral composite cov ntaub ntawv. Log caps feem ntau siv cov ntaub ntawv xws li PC/ABS, electroplated PC/ABS, heat{11}}resistant ABS, electroplated ABS, thiab PA/PPE. Lub hnab nqa khoom tuaj yeem ua los ntawm cov khoom siv xws li PC / PBT, PC / ASA, PC / ABS, thiab ASA. Sealing strips feem ntau yog ua los ntawm cov ntaub ntawv xws li EPDM roj hmab, PVC, thiab thermoplastic elastomers.
Lub teeb yuag yog ib qho irreversible qauv nyob rau hauv sab nrauv trim kev lag luam. In terms of material substitution, modified plastics (such as PP, ABS, and other composite materials) are comprehensively replacing traditional metal materials due to their low density and high℃of molding freedom. Hais txog cov txheej txheem kev hloov kho dua tshiab, kev nce qib hauv kev txhaj tshuaj molding, daim tawv nqaij molding, thiab cov txheej txheem foaming tso cai rau sab nrauv kom ua tiav cov duab ntau dua thiab cov phab ntsa nyias nyias thaum tuav lub zog. Tsis tas li ntawd, cov khoom siv tshiab tshiab xws li lub teeb yuag siv cov pa roj carbon fiber ntau thiab hemp fiber ntau nylon (PA6) cov khoom siv hauv tsheb sab nrauv tau tshwm sim.
