1.Dab tsi yog cov ntawv thov ua ntej-coated steel coils nyob rau hauv uas tsis yog-cov qauv sab nrauv ntawm lub cev tsheb?
Truck / Freight Cargo Boxes: Qhov no yog daim ntawv thov feem ntau thiab loj tshaj plaws, suav nrog cov tub yees tsheb thauj mus los thiab lub cev thauj khoom qhuav. Xim-coated coils (feem ntau yog galvanized substrate) muab kev tiv thaiv corrosion zoo heev thiab zoo li. Lub cev yog dov ncaj qha- tsim, ua rau yooj yim, qis- tus nqi, thiab cov txheej txheem ua haujlwm tau zoo.
Bus/Bus Sab Hauv thiab Sab Nrauv Vaj Huam Sib Luag: Xws li cov vaj huam sib luag ru tsev, sab phab ntsa vaj huam sib luag, thiab tsis yog - thauj khoom- coj cov tawv nqaij sab nrauv.
**SUV/MPV Roofs**: Qee cov qauv siv tau ua ntej- cov ntawv pleev xim rau cov ntawv hlau rau lawv lub ru tsev, tab sis qhov no yuav tsum muaj kev tiv thaiv huab cua ntau dua (UV tiv thaiv, pob zeb nti tiv thaiv) dua li cov xim siv tib yam -coated coils.
Engine Underbody Protection Phaj: Siv nyob rau hauv qee cov qauv, feem ntau xav tau kev tiv thaiv corrosion thiab muaj zog txaus.
Roj Hmab: Qee lub cav roj cav yog tsim los siv cov xim -coated coils nrog corrosion kuj zoo heev (xws li zinc-coated plates).
2.Dab tsi yog cov kev siv ntawm cov xim -coated steel coils nyob rau hauv automotive internal qhov chaw?
Ib puag ncig sab hauv yog qhov me me, tab sis yuav tsum muaj kev zoo nkauj, hnav tsis kam, thiab yooj yim ntawm kev tu.
Lub rooj zaum thiab cov ntsia hlau: Xim-coated steel muab kev tiv thaiv corrosion zoo heev, tiv thaiv xeb los ntawm kev sib xyaw los yog hws.
Seatbelt retractor vaj tse.
Ntau yam brackets thiab mounting daim hlau: xws li lub brackets, ECU vaj tse, thiab lwm yam.
Sunroof puag phaj.
3.Vim li cas nws tsis tuaj yeem siv rau lub cev tseem ceeb ntawm lub tsheb lub cev?
Kev cuam tshuam ntawm txheej txheej ntawm vuam txheej txheem:
Cov txheej txheem tseem ceeb hauv automotive lub cev tsim khoom yog qhov chaw vuam tsis kam. Cov txheej txheem organic nyob rau saum npoo ntawm pre- pleev xim rau steel coils yog ib qho insulator, uas cuam tshuam rau cov vuam tam sim no, ua rau cov vuam tsis muaj zog, tsis tiav welds, thiab paug thiab puas tsuaj rau cov vuam electrodes.
Thaum qhov no tuaj yeem hais los ntawm "pre-weld xim stripping," qhov no ua rau cov kauj ruam thiab cov nqi nce ntxiv, thiab nws nyuaj rau lav 100% kev ruaj ntseg thiab sib xws, uas yog qhov tsis txaus siab rau kev siv tshuab siab heev, thib ob-los ntawm- lub cev thib ob- hauv - cov kab ntau lawm.
Tshwj xeeb yuav tsum tau muaj zog thiab formability:
Automotive structural Cheebtsam feem ntau yog siv high-lub zog steel, ultra-siab-lub zog steel, thiab txawm kub- tsim steel. Cov hlau no tau txais kev kho tshwj xeeb metallurgical thiab dov txheej txheem kom ua tiav qhov hnyav thiab kev nyab xeeb.
Thaum lub substrate ntawm pre- pleev xim rau steel coils kuj muaj cov qib sib txawv zog, nws yog ib qho nyuaj rau ua tiav cov qib siab zog thiab complex formability yuav tsum tau rau automotive structural Cheebtsam.
Kev tsis sib haum xeeb hauv cov txheej txheem pleev xim:
Cov txheej txheem tseem ceeb rau lub cev tsheb yog ntau- txheej txheej txheej txheej ntawm "substrate + electrophoretic txheej + nruab nrab txheej + xim xim + lub tsho ntshiab." Ntawm cov no, cov txheej txheem electrophoretic yog qhov tseem ceeb, vim tias nws npog tag nrho cov kab noj hniav thiab qhov khoob, muab kev tiv thaiv kev tiv thaiv corrosion tshwj xeeb.
Yog tias siv ua ntej-coated xim-coated coils, kev kho electrophoretic tsis tuaj yeem ua, ua rau poob ntawm txheej tiv thaiv tseem ceeb tshaj plaws no.
4.Dab tsi yog cov kev cai tshwj xeeb rau cov khoom siv no hauv kev lag luam tsheb?
Txhim kho huab cua tiv thaiv: Resistant rau UV hluav taws xob muaj zog, kub thiab av noo voj voog, kua qaub nag, thiab lwm yam., PVDF los yog ultra-cov polyester coatings ruaj khov yog feem ntau siv.
Zoo formability: Cheebtsam yuav tsum tau stamping, thov kom lub txheej tsis tawg los yog tev thaum deformed nrog rau substrate.
Pob zeb nti tsis kam: tshwj xeeb tshaj yog rau cov khoom siv nyob rau hauv qis lossis sab nrauv ntawm lub tsheb lub cev, cov txheej txheem yuav tsum tau tiv thaiv los ntawm cov pob zeb me me.
Cov qauv nruj ib puag ncig thiab tsw ntxhiab: Cov khoom siv hauv tsheb sab hauv yuav tsum ua raws li cov kev cai nruj ntawm kev lag luam tsheb txog VOC (volatile organic compound) emissions thiab tsw.
5.Nws puas muaj feem xyuam rau lub tsheb lub cev - hauv - cov khoom siv dawb?
Tsis siv tau. Tej zaum yuav cuam tshuam nrog vuam, tsis tuaj yeem siv electrophoretically, lub zog / formability yuav tsis phim.
