Q1: Cov khoom siv substrate cuam tshuam li cas rau kev ua haujlwm ntawm cov xim -coated steel coils?
A1: Lub substrate yog "skeleton" ntawm cov xim -coated steel coil, txiav txim siab cov khoom ntawm cov khoom siv tshuab thiab cov peev txheej ua haujlwm, suav nrog:
Lub zog: Txiav txim siab qhov load ntawm cov ntawv hlau tuaj yeem tiv taus (xws li cua siab thiab daus siab), uas yog qhov tseem ceeb rau kev tsim vaj tsev.
Formability: Txiav txim seb cov ntawv hlau puas yuav tawg thaum khoov, stamping, kos duab sib sib zog nqus, thiab lwm yam kev ua haujlwm, cuam tshuam ncaj qha seb qhov chaw puas tuaj yeem tsim tau.
Surface Quality: Qhov flatness thiab deg mob ntawm lub substrate cuam tshuam rau qhov kawg tsos zoo ntawm cov xim -coated nto.
Q2: Dab tsi yog qee cov khoom siv substrate, thiab lawv txhais li cas?
A2: Cov ntaub ntawv substrate feem ntau muab faib ua ob pawg: dav dav - qib hom phiaj / stamping qib thiab qib qauv. Nkag siab cov qhab nia yog qhov tseem ceeb rau kev xaiv cov khoom raug.
Qeb|Cov Piv Txwv Qib Siab|Core Meaning Explanation
General -lub hom phiaj/Stamping Qib|DX51D, TXC51D
xwm 52d
DX53D, DX54D|D (Cold forming) + X (Rolled state) + 51-54 (Tus lej loj dua, qhov muaj zog dua qhov kev ua haujlwm stamping) + D (Kub-dip galvanized)
51=General-lub hom phiaj, 52=Stamping qib, 53=qib kos duab sib sib zog nqus, 54=Ntxiv- qib kos duab sib sib zog nqus.
Qib Qib|S250GD, S350GD
S550GD|S (Structural steel) + 250 (Qhov tsawg kawg nkaus yield zog, unit MPa) + G (kub kho) + D (Kub-dip galvanized) Tus lej sawv cev rau lub zog; Cov qib muaj zog muaj xws li 250, 280, 350, thiab 550.
Q3: Yuav ua li cas cov ntaub ntawv yuav tsum tau xaiv raws li lawv xav siv nyob rau hauv lub tsev thiab kev lag luam daim ntawv thov?
A3: Tus yuam sij rau kev xaiv yog ntsuas qhov nyuaj ntawm cov formwork nrog lub zog ntawm cov qauv.
Daim ntawv thov scenarios|Cov Ntsiab Lus Xav Tau|Pom zoo Substrate Khoom|Kev xav
Tsev ru tsev & phab ntsa|Dais cua, daus, thiab kev tsim kho loads, thaum tuav ib tug tej yam℃ntawm formability|Steel Qauv (S250GD - S550GD)|Prioritizes txaus lub zog los ris lub nra. Qhov yooj yim ntawm daim ntawv zoo, qhov ntau kom meej meej lub zog yuav tsum tau.
Khoom vaj tsev & rooj tog|Complex nkhaus nto, exquisite tsos, zoo machinability|Stamping hlau (DX52D - DX54D)|Ua ntej tshaj qhov sib sib zog nqus zoo heev - kos duab kev ua tau zoo thiab qhov chaw zoo kom tau raws li cov duab nyuaj thiab cov kev xav tau zoo nkauj.

Q4: Kuv yuav nkag siab li cas qib ntawm substrate rau xim -coated steel coils? Koj puas tuaj yeem muab piv txwv?
A4: Ua tiav qib ntawm cov xim -coated steel coils ua raws li txoj cai naming T + substrate yam ntxwv + + + substrate hom. Qhov twg, "T" sawv cev rau xim -coated steel ntawv.
Example 1: TDC51D+AZ
T: Xim - txheej txheej.
DC51D: Qhia tias nws cov substrate yog txias - tsim, dav -lub hom phiaj kub-dip galvanized substrate nrog nruab nrab stamping kev ua tau zoo.
+AZ: Qhia tias hom substrate yog kub-dip aluminium-zinc galvanized. Qib no yog tsim rau cov khoom siv hauv tsev nrog cov kev xav tau siab corrosion tab sis kuj yooj yim sib sau.
Q5: Yuav ua li cas xaiv cov ntaub ntawv tshawb fawb thiab tsis txhob muaj kev pheej hmoo thaum kev yuav khoom?
A5: Txhawm rau kom tsis txhob xaiv cov khoom tsis tsim nyog, peb pom zoo ua raws li peb kauj ruam no:
** Qhia kom meej cov ntsiab lus tseem ceeb:** Ua ntej, txiav txim siab seb koj cov khoom puas yuav tsum tau thauj khoom -cov kabmob muaj peev xwm (xaiv cov qauv hlau) lossis cov duab stamping nyuaj (xaiv stamping- qib steel). Qhov no txiav txim siab seb koj xaiv S-qib lossis D- qib steel.
** Them mloog zoo rau Zinc Ratio:** Qhov no yog qhov taw qhia tseem ceeb ntawm kev tiv thaiv corrosion ntawm qhov txiav. Cov mis laij lej yog: ib qho - sab txheej hnyav (g / m²) / substrate thickness (mm). Txhawm rau kom muaj kev tiv thaiv corrosion txaus ntawm qhov chaw txiav, qhov sib piv no yuav tsum siab dua lossis sib npaug ntawm 100. Piv txwv li, rau 0.5mm tuab steel phaj, ib qho -sab zinc txheej hnyav yuav tsum yog tsawg kawg yog 50g / m².
** Txheeb xyuas qhov Ua tiav Qib:** Qhia meej meej cov xim tiav -coated coil qib (xws li TS280GD+Z) hauv daim ntawv cog lus. Tsis txhob siv cov lus piav qhia tsis meej xws li "zoo" lossis "thawj-cov khoom lag luam" los xyuas kom meej tias cov khoom siv thiab kev ua tau zoo yog qhov tseeb.
