Tam sim no, nyob rau hauv lub ntiaj teb kev txhim kho Keynote ntawm kev hais txog cov ntaub ntawv tshiab thiab kev rov ua dua tshiab, thiab rov ua dua tshiab tau dhau los ua qhov kev coj ua tshiab ntawm kev siv tsheb tshiab Cov ntaub ntawv. Uas tau tsav los ntawm nthwv dej lub teeb yuag, cov ntaub ntawv Yas tau siv ntau dua hauv kev thaj teb vim yog lawv cov nyhuv muaj kev txo qis. Seb nws yog sab nrauv cov khoom hniav zoo nkauj ntawm lub tsheb xws li lub twj paj nruag vaj huam sib luag, lub rooj zaum ntawm lub rooj zaum, lub rooj tom qab, lossis cov qauv chaw, Koj tuaj yeem pom cov duab ntxoov ntxoo ntawm cov yas txhua qhov chaw. Tshwj xeeb tam sim no tam sim no, lub zog hluav taws xob tshiab tau dhau los ua cov kev hloov pauv tseem ceeb thiab kev txhim kho ntawm kev lag luam tsheb thoob ntiaj teb. Lub teeb yuag ntawm cov tsheb hluav taws xob hluav taws xob tshiab yog qhov maj ntau dua li cov tsheb tsoos. Daim ntawv thov tau txais cov ntaub ntawv yas tau nthuav mus rau tshiab lub tsheb tshiab lub tsheb roj teeb thiab lwm yam. Nyob rau tib lub sijhawm, cov nplaim taws retardant, kev tiv thaiv ib puag ncig ib puag ncig, siab tsis kam thiab lwm yam kev ua tau zoo thiab lwm yam kev ua tau zoo dua yuav muab cov nyom ntau dua.
Daim ntawv thov ntawm ob peb yas cov ntaub ntawv feem ntau siv hauv automotives
PA
Polyamide PA feem ntau hu ua Nylon. Cov cuab yeej zoo heev, tensile, compressive thiab coj tsis kam. PA6, PA66, Txhim Kho Cov Hluav Taws Xob Retardant Pa6 yog siv rau hauv Automotive CAV thiab lub cav rooj npog, lub tog raj kheej taub, Wiper, Wiper, Radia Radiator Grille, thiab lwm yam.
Pa66
PA66 tau txais los ntawm Polycondensation ntawm cov adipic acid thiab hexandiamine ntawm daim ntawv me me ntawm 1: 1. Adipic acid feem ntau yog tsim los ntawm hydrogenation ntawm kev ntshiab benzene thiab oxidation nrog nitric acid. PA66 tuaj yeem tswj lub zog muaj zog thiab txhav ntawm qhov kub siab dua; PA66 muaj kev nyuaj siab txhua yam, kev nyuaj siab zoo tawg tsis kam, thiab yog qhov zoo tshaj plaws coj kam tiv taus nylon; Pa66 tus kheej lubricating zoo heev, thib ob tsuas yog rau PTFE thiab polyformaldehyde; PA66 muaj cov khoom zoo thermal thiab yog cov khoom siv ua kom tus kheej, tab sis nws cov dej nqus yog qhov loj me, yog li nws qhov seem ruaj khov yog qhov tsis zoo.
PA6 + GF30
PA6 GF30 yog qhov tshwm sim ntawm kev hloov kho PA6. PA6 GF30 txhim kho cov khoom muaj cov khoom los ntawm kev ntxiv cov iav fibers. Iav fiber nws tus kheej muaj kub ua kom tsis kam, nplaim taws ua hauj, kev rwb thaiv tsev kom sov, rwb thaiv tsev hluav taws xob kub. Tom qab txhawb los ntawm cov iav fiber ntau, pa6 gf30 cov khoom tuaj yeem ua tau raws li cov kev xav tau ntawm kev lag luam thiab muaj lub zog txhua hnub, cov kev tsis kam thiab qhov chaw ruaj khov.
PMMA + ASA
PMMA, feem ntau hu ua "Pleexiglass". Nws muaj lub teeb pom zoo zoo, cov khoom siv tshuab thiab kev ua tau zoo heev thiab huab cua tsis kam. Tab sis nws brittleness yog siab, yooj yim rau tawg, cuam tshuam tsis zoo.
Asa, zoo sib xws nyob rau hauv tus qauv rau ABS, siv Acrylic Roj Hmab tsis muaj ob chav sib yuav siv cov roj hmab butadiene tsis muaj menyuam. Tau zoo heev yooj yim, huab cua zoo tsis kam, thiab zoo dua tsis kam mus rau tshuaj corrosion. Tab sis nws cov npoo tawv tsis yog siab, khawb tiv taus, hnav tsis kam tsis zoo.
Abs
Abs yog acryloniturile - Butadiene - Styrene Copolymer, cov kev cuam tshuam hluav taws xob, cov khoom siv kub tsis muaj zog, cov ntsej muag zoo ruaj khov, cov ntsej muag zoo nkauj, Mas siv rau cov pa tsheb txias txias, hloov, ntsuas kev tiv thaiv ib puag ncig, cov kab xev, cov tswv yim kev nyab xeeb, thiab lwm yam.
PC / Abs alloy
PC / ABS (P Acrylonitrile - Butadiene - Styrene Copolymer alloy): Qhov zoo ntawm PC yog qhov nyuaj thiab nyuaj yog kev nyuaj siab tawg, viscosity; Qhov zoo ntawm abs yog cov zoo nkauj, tab sis tsis tshua muaj kev nyuaj siab saum npoo av; Nyob rau hauv txoj kev no, cov khoom siv sib xyaw P / Abs khaws cov txiaj ntsig ntawm ob qho; PC / ABS muaj cov tawv tawv siab, muaj kev ntxhov siab thiab tawv, thiab kev ntxhov siab ntau; Nws cov yam ntxwv txhua yam nyob nruab nrab ntawm. PC / ABS Alloy nyob rau hauv lub tsheb dashboard, qhov rooj kov, kho hniav lub log, cov pa taws teeb, tw teeb pom kev zoo thiab ntau lwm qhov chaw siv.
Kev tsim kho yav tom ntej ntawm Automotive Plastics
Muaj cov neeg tau txais kev pab xav tau rau roj-tau txais, ruaj thiab lub tsheb loj heev yuav txhawb qhov kev thov rau kev lag luam hauv tsheb. Ntawm cov plastics siv nyob rau hauv tsheb, siv tus nqi ntawm cov yas (xws li PP, PE, ABS, thiab lwm yam.) Xws li PBT, PBT, thiab lwm yam Cov.) Cov nyiaj tau txog 18%. Yog li ntawd, rau cov tsheb niaj hnub, txawm nws yog kev kho kom zoo sab hauv, lossis cov kev ua kom tau zoo ntawm cov khoom yas siv cov khoom siv hlau, uas yog, lub tsheb kho tsheb ntawm "yas hloov ntawm cov hlau "sib tshuam.
