1.Vim li cas galvanized coils haum rau ntiav stamping?
Kev ua tau zoo ntawm substrate:
Lub substrate rau galvanized coils feem ntau yog siab -zoo qis- carbon steel (xws li SPCC, DC01, thiab lwm yam). Hom hlau no muaj cov yas zoo heev thiab ductility, ua rau nws nyiam cov khoom siv rau stamping (suav nrog ntiav stamping).
Lubricating nyhuv ntawm Zinc Txheej:
Cov txheej zinc ua raws li cov khoom siv roj nplua nyeem thaum lub sij hawm stamping, txo kev sib txhuam ntawm cov tuag thiab cov ntawv hlau, ua kom cov khoom ntws, txo cov stamping siab thiab tuag hnav, yog li txhim kho stamping zoo thiab tuag lub neej.
Nto Zoo:
Electro-galvanized coils, tshwj xeeb tshaj yog, muaj qhov sib luag, zoo ib yam nrog cov zinc paj zoo nkauj, ua rau lawv zoo tagnrho rau ntiav- stamped qhov chaw uas xav tau kev zoo nkauj zoo nkauj thiab cov txheej txheem tom qab pleev xim lossis txheej txheej.
Combined Formability thiab Corrosion Resistance:
Qhov no yog qhov zoo tshaj plaws ntawm galvanized steel coils. Thaum muab kev ua haujlwm zoo tshaj plaws, lawv kuj tseem cuam tshuam zoo rau kev tiv thaiv corrosion rau cov khoom, tshem tawm qhov xav tau tom qab electroplating lossis pleev xim rau kev tiv thaiv xeb. Lawv tau siv dav hauv cov khoom siv hauv tsev, tsheb, kev tsim kho, thiab lwm yam.
2.Yuav ua li cas xaiv hom galvanized kauj?
Electro-galvanized coils: zinc txheej yog thinner (feem ntau tsawg dua 30μm), zoo ib yam, thiab muaj ib tug du nto nrog muaj zog adhesion rau substrate. Rau qhov chaw uas yuav tsum tau thav duab ntiav thiab cov qauv zoo nkauj, electro-galvanized coils feem ntau nyiam vim tias cov zinc txheej tsis tshua muaj kev tawg lossis tev tawm thaum lub sijhawm tsim.
Kub-dip galvanized coils: zinc txheej yog tuab dua (feem ntau yog 35-}200μm), muab kev tiv thaiv corrosion zoo dua, tab sis qhov saum npoo yog qhov ntxhib, nrog cov zinc spangles pom, thiab nkig alloy txheej txheej ntawm zinc txheej thiab hlau. Thaum lub sij hawm stamping, cov txheej zinc thicker yog feem ntau ua rau micro- tawg thiab txawm tev, cuam tshuam rau cov tsos thiab hauv cheeb tsam corrosion kuj. Yog tias kub-dip galvanizing raug xaiv, ntau yam uas tsis muaj lossis me me zinc spangles yuav tsum raug xaiv, thiab qhov tob stamping yuav tsum tau tswj nruj me ntsis.
3.Qhov adhesion ntawm zinc txheej cuam tshuam li cas stamping kev ua tau zoo?
Stamping deformation ua rau cov zinc txheej yuav ncab. Yog tias qhov adhesion ntawm zinc txheej thiab cov substrate tsis zoo, tev thiab flaking yuav tshwm sim. Yog li ntawd, nws yog ib qho tsim nyog yuav tau xaiv cov ntaub ntawv uas muaj cov qib adhesion siab (xws li, txheeb xyuas los ntawm kev ntsuas kev khoov thiab kev ntsuas cupping).
4.Dab tsi yog qhov cuam tshuam ntawm kev kho deg thiab lubrication ntawm kev ua haujlwm stamping?
Passivation txheej: Qhov no los ntawm ntau hom, xws li chromium-dawb passivation thiab roj-coated passivation. Qee cov khaubncaws sab nraud povtseg yog qhov nyuaj heev thiab tuaj yeem flake tawm mus rau hauv cov hmoov thaum lub sij hawm stamping, accelerating tuag hnav. Txoj kev kho mob passivation tsim nyog yuav tsum raug xaiv raws li qhov nyuaj ntawm cov txheej txheem stamping, lossis kev sab laj nrog cov khoom siv yog tsim nyog.
Lubrication: Txawm hais tias lub galvanized coil muaj nws tus kheej xeb- cov roj tiv thaiv, cov roj stamping ntxiv yuav tsum tau siv thaum lub sij hawm stamping kom muab lubrication txaus, xyuas kom zoo zoo, thiab tiv thaiv khawb.
5.Dab tsi yog qhov cuam tshuam ntawm pwm tsim thiab kev mob ntawm kev ua haujlwm stamping?
Tuag Clearance: Qhov tuag clearance rau stamping galvanized steel los xij yuav tsum yog me ntsis loj dua li ntawd rau stamping txias -rolled nplooj ntawv ntawm tib tuab. Vim tias zinc txheej nws tus kheej muaj tuab, yog tias qhov kev tshem tawm tsawg dhau, nws yuav ua rau cov zinc txheej, ua rau zinc scraping, zinc txheej tev, thiab txawm tias tuag thaiv.
Tuag Khoom thiab Hardness: Nws raug nquahu kom siv cov khoom siv tuag nrog kev hnav zoo dua (xws li hmoov hlau metallurgy) thiab ua cov kev kho saum npoo (xws li TD kev kho mob lossis PVD txheej) kom tiv thaiv kev hnav los ntawm zinc txheej.
Tuag Nto Ua tiav: Cov kab noj hniav tuag thiab txiav ntug yuav tsum muaj qhov ua tiav siab kom txo tau kev sib txhuam thiab tiv thaiv khawb ntawm qhov chaw galvanized.
