1.Dab tsi yog qee qhov kev thov tau zoo?
Rooj thav duab thiab adjusters: Qhov no yog daim ntawv thov classic tshaj plaws ntawm txias-rolled steel nyob rau hauv sab hauv trim. Yuav tsum muaj qhov zoo li qub thiab muaj kev cuam tshuam loj heev, thiab xav tau lub zog siab thiab ua haujlwm ntev, siab -lub zog txias- dov steel yog qhov kev xaiv zoo tshaj plaws.
Seat belt fasteners/retractor vaj tse: Kuj siab -kev nyab xeeb muaj zog- cov khoom muaj feem xyuam, feem ntau yog ua los ntawm txias- dov steel.
Cov kev txhawb nqa zais zais: Xws li cov kab sib dhos thiab cov kab sib dhos hauv lub dashboard, thiab tiv thaiv - cov kab sib tsoo thiab cov phaj txuas ntxiv hauv lub qhov rooj vaj huam sib luag. Cov khoom no tau ntim rau hauv cov tawv nqaij sab hauv thiab ua npuas ncauj, tsis pom ncaj qha, tab sis yuav tsum tau muab kev txhawb nqa zoo rau tag nrho cov khoom siv sab hauv.
Cov ntaub ntawv hauv paus rau qee cov khoom siv ua haujlwm: xws li cov cuab yeej tuav tes, thiab cov ncej rau qee qhov chaw cia khoom.
2.Vim li cas thiaj li hais tias muaj "kev txwv nruj"?
Tsis zoo Corrosion Resistance (fatal Weakness):
Txias-cov nplooj ntawv steel yog "cov ntawv liab qab" tsuas yog ib txheej nyias ntawm cov roj los tiv thaiv- xeb ntawm qhov chaw, ua rau lawv tsis tshua muaj rusting. Ib puag ncig sab hauv ntawm lub tsheb tsis qhuav tag (piv txwv li, cov dej noo coj los ntawm cov neeg caij tsheb, cov dej haus nchuav, cua txias condensation, thiab lwm yam).
Kev daws: kev kho saum npoo yog tsim nyog. Cov txheej txheem feem ntau yog electroplating (xws li galvanizing), electrophoresis, los yog txau nrog cov tshuaj tiv thaiv -corrosion coatings. Txawm li cas los xij, qhov no nce cov txheej txheem thiab cov nqi.
Qhov hnyav:
Piv nrog rau cov ntaub ntawv xws li plastics thiab magnesium{0}}aluminium alloys, steel muaj qhov ntom ntom dua, uas ua rau muaj kev puas tsuaj rau lub tsheb sib sib zog nqus, yog li cuam tshuam rau kev siv hluav taws xob thiab emissions. Qhov no yog qhov laj thawj tseem ceeb vim li cas nws thiaj li maj mam hloov qee qhov (piv txwv li, los ntawm kev siv siab -lub zog steel lossis engineering plastics).
Formability thiab Design Limitations:
Complex peb-cov duab puab sab hauv (xws li streamlined dashboards thiab qhov rooj vaj huam sib luag nrog nkhaus textures) yog qhov nyuaj rau kev siv cov ntawv hlau los ntawm stamping, ua rau cov nqi pwm siab. Yas txhaj molding muaj qhov zoo sib xws hauv qhov no.
3.Dab tsi yuav tsum tau xav txog thaum txiav txim siab seb puas yuav siv cov txias-rolled coils los tsim cov khoom sab hauv?
Component Function: Puas yog lub load-cov kabmob cov khoom siv lossis cov khoom siv kho kom zoo nkauj?
Cov Nqi Them Nqi: suav nrog tag nrho cov nqi ntawm cov khoom siv, kev ua, thiab kev kho saum npoo.
Lub Hom Phiaj Nyhav: Nws puas ua raws li lub tsheb lub teeb pom kev zoo?
Corrosion Protection Requirements: Txiav txim siab qhov kev tiv thaiv corrosion raws li qhov chaw nyob (piv txwv li, ze rau hauv pem teb).
4.Dab tsi yog qee yam khoom siv hloov kho dua tshiab?
Galvanized steel ntawv (SECC): Ib txheej ntawm zinc yog siv rau txias -rolled steel ntawv, ho txhim kho corrosion kuj; qhov no yog qhov kev xaiv ntau dua.
Aluminium ntawv: Lub teeb yuag thiab corrosion-resistant, tab sis kim dua.
Engineering plastics (xws li PP, ABS, PA, thiab nylon): Lub teeb yuag, muab kev ywj pheej tsim kev ywj pheej, tiv thaiv corrosion, thiab yooj yim kom ua tiav qhov muag muag - kov; lawv tau dhau los ua cov ntaub ntawv tseem ceeb rau cov khoom siv sab hauv thiab sab nrauv thiab semi- cov khoom siv.
Cov ntaub ntawv sib xyaw: xws li ntev - fiber ntau reinforced plastics, muaj zog mus txog ntawm cov hlau thaum sib dua.
5.Yuav ua li cas kom meej meej faib cov khoom?
Siab -lub zog, zais cov khoom siv: Ua tau. Piv txwv muaj xws li rooj zaum ncej thiab dashboard beams. Qhov no yog qhov tshwj xeeb ntawm txias- dov / galvanized steel.
Cov tsos mob, cov khoom siv kho kom zoo nkauj, thiab cov duab nyuaj: Tsis ua tau / tsis muaj nqis. Cov ntaub ntawv xws li plastics yuav tsum tau ua ntej.
