1.Dab tsi yog kev siv ua ntej-coated steel rolls nyob rau hauv tsheb sab hauv?
Automotive sab hauv trim panels: xws li lub qhov rooj vaj huam sib luag, thiab lub thav duab lossis sab nraum qab ntawm qee qhov ntsuas vaj huam sib luag. Ua ntej- cov ntawv coated steel muaj ua ntej- siv xim thiab textures, tshem tawm qhov xav tau rau kev pleev xim rau theem nrab, ua rau tus nqi qis dua thiab zoo nkauj dua.
Headliner thiab pillar guards: pab raws li kev txhawb nqa lossis cov txheej txheem zoo nkauj.
Lub hnab ntim khoom / txee hauv ob sab phlu: tiv thaiv lub tsheb lub cev qauv, tiv thaiv khawb ntawm cov khoom thauj, thiab txhim kho kev zoo nkauj.
Lub rooj zaum / backrests: qee lub tsheb lag luam lossis tsheb kev lag luam siv ua ntej-cov ntawv hlau coated rau lawv lub rooj zaum, ntsuas kev tiv thaiv xeb thiab nqi.
2.Dab tsi yog cov kev siv ntawm cov xim -coated steel coils nyob rau hauv automotive sab nrauv qhov chaw?
Kev lag luam tsheb thauj khoom lub thawv: Lub hauv ob sab hauv ntawm lub thawv ntim khoom ntawm cov tsheb thauj khoom thiab cov tsheb thauj khoom, nquag siv rau kev thauj khoom thiab tshem tawm, yuav tsum hnav tsis kam thiab tiv thaiv xeb.
Bus sab hauv trim: Xws li cov phab ntsa sab hauv thiab qab nthab ntawm cov tsheb npav.
Cov vaj huam sib luag tiv thaiv hauv qab: Qee qhov tsis yog - cov vaj huam sib luag siv los tiv thaiv thiab tiv thaiv plua plav tuaj yeem siv tuab - ntsuas ua ntej- cov ntawv hlau coated.
Muffler vaj tse: Qee cov qauv siv tau ua ntej- cov ntawv hlau coated nrog cov ntawv tshwj xeeb siab- kub resistant coatings raws li cov ntaub thaiv npog tshav kub, tab sis qhov no yuav tsum tau cov txheej txheem kom muaj cov cua sov siab heev.
3.Vim li cas ua ntej-coated steel yob tsis siv rau sab nrauv panels ntawm lub cev tsheb?
Extreme Requirements rau txheej zoo thiab tsos
Automotive txheej txheej sab nrauv yuav tsum muaj siab gloss, muaj kev xav, xav, thiab xim zoo nkauj. Current color-coated coil production processes (roller coating + rapid baking) struggle to achieve the mirror-like finish and depth of original automotive paint.
Automotive manufacturers utilize a multi-layer spraying system-cathodic electrophoresis + intermediate coat + color paint + clear coat-which far surpasses the single- or double-layer coatings of color-coated coils in terms of corrosion resistance, stone chip resistance, huab cua tsis kam, thiab tsos.
Formability thiab Weldability
Kev kos duab sib sib zog nqus: Automotive lub cev qhov chaw tau dhau los ua qhov sib sib zog nqus kos duab deformation. Cov txheej txheej ntawm cov xim -coated coils yog qhov cuam tshuam rau kev tawg thiab txawm tias tev nyob rau hauv qhov hnyav li no. Hauv qhov sib piv, automotive-qib "liab qab" steel ntawv (xws li cov ntawv galvanized) yog coated tsuas yog tom qab stamping, zoo kawg nkaus zam qhov teeb meem no.
Vuam txheej txheem: Resistance qhov chaw vuam yog dav siv nyob rau hauv automotive lub cev. Cov txheej txheej ntawm cov xim -coated coils yog ib qho insulator, uas cuam tshuam nrog cov vuam tam sim no, ua rau vuam tsis ua hauj lwm lossis tsis muaj zog welds. Lub tuam txhab tsheb siv cov ntawv tsis muaj coated, tshwj xeeb welded galvanized steel los xij.
Kev Kho thiab Kev Sib Raug Zoo
Kos yog inevitable hauv kev tsim tsheb. Cov nplooj ntawv hlau liab qab tuaj yeem raug xuab zeb thiab kho ua ntej pleev xim. Txawm li cas los xij, pre-coated steel coils yog pre-coated cov ntaub ntawv; ib zaug puas lawm, lawv tsis tuaj yeem kho zoo kawg nkaus ntawm cov kab ntau lawm.
Kev tswj cov khoom sib xws ntawm lub tsheb cov xim yog qhov nyuaj rau kev sib koom tes ntawm cov ntawv hlau steel thiab lub Hoobkas tsheb dua li kev tswj cov kab ntau lawm hauv lub tsheb lub Hoobkas nws tus kheej.
4.Dab tsi yog cov kev cai tshwj xeeb rau xim -coated coils siv nyob rau hauv tsheb qhov chaw?
Substrate: Siab-cov ntawv zoo galvanized steel feem ntau yog siv los xyuas kom muaj kev tiv thaiv corrosion thiab formability.
Txheej: Ib puag ncig tus phooj ywg txheej yuav tsum tau ua kom tau raws li kev lag luam tsheb VOC txwv. Cov kev xav tau siab dua kuj tau muab tso rau ntawm cov txheej txheem abrasion tsis kam thiab tshuaj lom neeg ua haujlwm.
Kev ruaj ntseg zoo: Cov txheej txheej yuav tsum ua raws li cov qauv zoo ntawm kev lag luam tsheb, xws li IATF 16949, kom ntseeg tau tias kev ua haujlwm ruaj khov thiab kev taug qab.
5.Dab tsi yog qhov tseem ceeb ntawm daim ntawv thov ntawm cov xim -coated steel coils hauv tsheb qhov chaw?
Kev sib ntaus sib tua tseem ceeb: Automotive sab hauv trim thiab cov khoom siv, nrog rau kev lag luam tsheb thauj khoom, thiab lwm yam. Ntawm no, nws tau yeej kev lag luam vim nws cov nqi qis, kev ua haujlwm siab, thiab zoo corrosion kuj thiab cov khoom zoo nkauj.
Cov cheeb tsam uas npaj txhij txog: Cov neeg caij tsheb sab nrauv lub cev panels. Ntawm no, nws infeasibility nrog vuam thiab heev sib sib zog nqus daim duab, raws li zoo raws li nws tsis muaj zog nyob rau hauv ua kom tiav cov tsos zoo uas yuav tsis phim ib txwm painting, cais nws.
