Q1: Dab tsi yog "zoo ib yam substrate" ntawm cov xim -coated steel ntawv? Nws cov yam ntxwv tseem ceeb yog dab tsi?
A1: Cov "zoo ib yam substrate" ntawm cov xim-coated steel sheets feem ntau yog hais txog cov hlau xws li DX51D thiab TDC51D, siv rau kev ua kom txias. Nws lub zog tawm los yog feem ntau ntawm 260-320 MPa, thiab nws cov txiaj ntsig tseem ceeb nyob hauv nws cov kev ua tau zoo heev thiab cov nqi sib tw heev.
Qhov kev ua tau zoo ntawm hom substrate no yog qhov tseeb heev: nws tsis yog tsim los tiv thaiv cov khoom loj, tab sis kom yooj yim ua tiav ntau yam duab thaum khaws cov nqi tswj. Piv txwv li, TDC51D- theem zoo tib yam substrate tuaj yeem ua tau raws li feem ntau ntawm txhua hnub stamping, khoov, thiab lwm yam kev xav tau.
Q2: Dab tsi yog qhov tshwj xeeb zoo ntawm cov txheej txheem substrates ntawm kev ua haujlwm?
A2: Kev ua tau zoo yog qhov zoo tshaj plaws ntawm cov txheej txheem substrates. Yog tias cov khoom kawg muaj cov duab uas xav tau ntau yam khoov thiab kos duab sib sib zog nqus, cov txheej txheem substrates yog qhov kev xaiv zoo dua.
Advanced hauv kev ua haujlwm nyuaj: Piv nrog rau siab - steel zog (Qib S) uas yog qhov tseem ceeb ntawm lub zog, cov txheej txheem substrates (Qib D) zoo li "cov hlau me me," uas muaj qhov ua tau zoo dua thiab ductility. Thaum tsim cov txheej txheem nyuaj xws li kev kos duab sib sib zog nqus thiab flanging yog qhov yuav tsum tau ua, nws tiv thaiv kev tawg thiab txheej txheej txheej thaum ua.
Qhov kev xaiv zoo tshaj plaws rau cov khoom siv hauv tsev thiab cov ntawv hlau: Vim li no, cov txheej txheem substrates tau dav siv rau cov khoom siv hauv tsev (xws li cov tub yees thiab cua txias), rooj tog zaum, thiab cov ntawv hlau txhua hnub uas xav tau kev zoo nkauj thiab cov tsos zoo nkauj.
Q3: Hauv qhov xwm txheej twg yog cov txheej txheem substrates tsim nyog tshaj? Hauv qhov xwm txheej twg lawv yuav tsum zam?
A3: Tus yuam sij rau kev xaiv yog nyob rau hauv kev sib piv nrog cov kev txwv.
✅ Zoo tshaj (pom zoo)
Sab hauv thiab Sab Nrauv Kho Kom Zoo Nkauj: Cov qhov cua nkag, lub qab nthab, cov khoom faib, thiab lwm yam., qhov tsis muaj qhov tshwj xeeb yuav tsum muaj zog.
General Sheet Hlau Ua: Hluav taws xob lub thawv casings, billboards, niaj hnub ntawv hlau qhov chaw, thiab lwm yam.
Tsawg-Tus nqi, luv luv- Kev Tsim Kho Lub voj voog: Lub tsev khaws khoom ib ntus thiab cov chaw tsim khoom yooj yim hauv thaj chaw hauv av, tsim los rau kev ua neej nyob ntawm 5-10 xyoo, cov haujlwm uas muaj peev txheej tsawg.
Kev Tsim Khoom Siv Hauv Tsev: Casings thiab cov khoom siv sab hauv ntawm cov khoom xws li tub yees thiab tshuab ntxhua khaub ncaws.
Tsis haum (tsis txhob siv):
High-load structures: Load-cov kabmob ru tsev loj-span vaj tse, sab nrauv phab ntsa ntawm siab-nce vaj tse, loj warehouse racks, thiab lwm yam scenarios yuav tsum tau muaj zog.
Ib puag ncig corrosive heev: thaj chaw ntug hiav txwv raug cov tshuaj ntsev ntau, lossis thaj chaw uas muaj kev sib cuag nrog cov kua qaub thiab alkalis ntev, xws li cov nroj tsuag tshuaj thiab ua liaj ua teb.
Q4: Yuav ua li cas yuav tsum sib npaug ntawm kev xaiv ntawm cov substrates zoo tib yam thiab siab - lub zog substrates (cov qauv hlau)?
A4: Qhov no yog qhov tseem ceeb ntawm kev ua haujlwm ntawm kev ua haujlwm thiab lub zog ntawm cov qauv, yuav tsum muaj kev lag luam tawm - tawm raws li qhov yuav tsum tau ua.
Ordinary substrates: Yield zog kwv yees li 300 MPa. Lawv qhov zoo yog nyob rau hauv tus nqi qis thiab kev ua haujlwm zoo dua, ua rau lawv tsim nyog rau cov ntawv thov uas tsis tshua muaj zog yuav tsum tau ua. Lawv cov kev txwv yog txwv tsis pub thauj khoom- cov kabmob muaj peev xwm, ua rau lawv tsis haum rau cov qauv hnyav-.
Siab -lub zog substrates (cov qauv hlau): Xws li S350GD thiab siab dua, cov khoom muaj zog tuaj yeem ncav cuag 350-550 MPa. Lawv qhov zoo yog lub zog siab, tso cai rau lub peev xwm thauj khoom muaj zog nrog cov ntaub ntawv nyias, ua kom "lub teeb yuag" tsim. Lawv cov kev txwv yog tus nqi siab dua thiab kev ua haujlwm nyuaj dua.
Nyob rau hauv luv luv: Yog hais tias koj cov khoom yuav tsum complex shaping zoo li cov khoom siv tes ua, xaiv ib tug zoo tib yam substrate; yog tias nws yuav tsum tau nqa cov khoom hnyav xws li nqa dej, xaiv qhov siab - lub zog substrate.
Q5: Dab tsi yog qee qhov yooj yim saib xyuas kev lag luam hauv tus nqi thiab kev yuav khoom?
A5: Thaum yuav khoom, tsis txhob saib "tus nqi" xwb; xam qhov "tag nrho cov nqi ntawm lub neej" yog qhov tseem ceeb rau kev txuag tiag. Nov yog ob yam tseem ceeb:
Cov Nqi Khoom Siv: Cov txheej txheem ib txwm muaj qhov zoo dua qub hauv cov nqi pib yuav khoom. Nyob rau hauv tag nrho cov nqi ntawm cov xim -coated steel los xij, tus nqi substrate nyiaj ntau npaum li 60% mus rau 70%, ua nws cov nqi tseem ceeb ntawm high- lub zog substrates. Rau pob nyiaj siv - cov haujlwm tseem ceeb, xaiv cov substrates zoo tib yam tuaj yeem txuag tau cov nuj nqis ntau heev.
Cov Nqi Kho Mob: Tsis txhob xaiv cov substrates zoo tib yam hauv qhov chaw corrosive kom txuag tau nyiaj. Piv txwv li, ib rooj plaub qhia tau hais tias ib txoj haujlwm cog qoob loo ntawm ntug dej hiav txwv siv cov xim galvanized polyester zoo tib yam - cov ntawv hlau coated kom txuag tau nyiaj, ua rau xav tau kev hloov pauv tom qab tsuas yog 10 xyoo vim muaj kev xeb ntau. Ua ke nrog kev poob los ntawm kev tsim khoom poob qis, qhov kawg tag nrho cov nqi deb tshaj qhov kev cia siab.
