1. Txhua qhov yog qhov txias ua haujlwm hloov tau ntawm kub- dip galvanized states states states?
Cov khoom lag luam puas zoo: Cov ntshiab Zinc Txheej cov khoom pov thawj zoo heev yas (elongation ntawm kwv yees li 20%). During conventional cold bending operations (such as 180℃flat bends and 90℃right-angle bends), the zinc layer stretches and contracts synchronously with the steel substrate, preventing cracking or flaking. (Kev saib xyuas yuav tsum tau ua kom tsis txhob muaj -} bending, uas tuaj yeem ua rau lub zos thinnius yuav tsum muaj ntau dua los yog sib npaug ntawm cov hlau tuab.)
Piv txwv li, thaum ua cov kub kub - dip galvanized cov kab ke yog ua tau yam tsis muaj kev sib luag ntawm cov txheej zinc.
Stable stamping properties: For shallow and medium-strength parts (such as appliance back panels and small automotive brackets), hot-dip galvanized steel sheets can be stamped using dies without delamination or powdering of the zinc layer due to stamping stress. For deep drawing (e.g., complex curved parts), grades combining a low-alloy, high-strength substrate with a thin zinc layer (such as DC03 with hot-dip galvanizing) are recommended, achieving a balance between formability and protection. Reliable rolling/curling performance: In continuous rolling processes such as pipes and steel roll-up doors, hot-dip galvanized steel sheets can withstand repeated rolling deformation. The bonding strength between the zinc layer and the substrate (usually >100MPA) tuaj yeem tiv thaiv lub zog shear thaum lub sij hawm yob thiab tiv thaiv cov txheej zinc los ntawm kev poob.
2.What yog lub vuam hloov tau ntawm kub - dip galvanized states hlau?
Tau tshaj tawm ntau hom vuam Cov thaiv cov vuam mus rau suppress Zinc Vapor Porosity).
Guaranteed Weld Zog: Tom qab vuam, lub zog ntawm lub chaw weld feem ntau yog cov hlau substrate (piv rau lub zog ntawm cov hlau loj voov voov). Tsuas yog thov ib qho "re - galvanizing pleev xim" lossis "txias zinc tawg" kho kom huv rau weld℃tuaj yeem kho tau tag nrho corrosion.
Piv txwv li, thaum vuam kub - dip galvanized steel teeb tsa lub tsev muaj peev xwm ua tiav weld lub zog tshaj 90% ntawm lub zog weld.
Tsis muaj kev pheej hmoo ntawm weld embrittlement: zinc txheej tsis tau sau loj paphes nrog cov hlau subthales (xws li cov sib xyaw ua ke hauv qee lub tsho tiv no), tswj hwm cov tawv nqaij ntawm cov hlau phaj tom qab vuam. Qhov no ua rau nws tsim nyog tshwj xeeb rau kev siv hlau ua ke hauv cov khoom siv hauv qis - sov ib puag ncig).
3.Qhov yog qhov kev txiav kev hloov tau ntawm kub - dip galvanized steel phiaj?
Neeg kho tshuab tej (txias txiav): xws li shearing, laser txiav, thiab ntshav txiav (txias txiav). Thaum lub sij hawm txiav cov txheej txheem, cov zinc txheej tsis tsim molten lub ntsej muag, ua rau cov npoo txiav du. Tsuas yog "zinc Slag" (ib qho me me adhering rau kev txiav tawm ntawm kev sib tsoo) yuav tsum tau muab tshem tawm ua ntej kev ua tiav (xws li vuam lossis khoov) tuaj yeem ua mus ncaj qha.
Piv txwv li, thaum Laser txiav kub - dip galvanized steel los yog mus cuag ± 0.1mm, txheej zinc tsis muaj kev cuam tshuam ntawm kev txiav qhov tseeb.
Thermal tej (nplaim txiav): haum rau txiav tuab daim hlau (ntau dua los yog sib npaug rau 8 hli). Thaum txiav, lub zinc txheej hlawv nrog cov nplaim taws los ua cov dav hlau txiav thiab tuaj yeem muab tshem tawm ntawm qhov chaw siab lossis sib tsoo yam tsis muaj kev cuam tshuam.
4.What yog qhov yoog tau ntawm kev kho sab nraud tom ntej ntawm kub - dip galvanized steel ntawv?
Yooj Yim Degreeze thiab xeb thiab hmoov av rau ntawm kub - dip galvanized saum npoo av tuaj yeem tshem tawm nrog cov qauv kev daws teeb meem (xws li alkaline degrees daws). Cov txheej zinc txheej nws tus kheej tseem xeb {{2} Pub dawb, tshem tawm cov kev xav tau ntawm cov txheej txheem.
Zoo heev txheej adhesion: tom qab degreasing, kub {{0} {- ua xim pleev xim (xws li epoxy pleev xim). Cov txheej txheej nplaum (hla- Hatch Kuaj mus txog qib 0) yog qhov zoo dua li ntawm cov hlau (uas yog lub cev ua kom lub cev tawm).
Piv txwv li, kub - dip galvanized sab yees muaj kev lag luam hauv tsev muaj kev lag luam hauv tsev muaj kev lag luam thiab kasppment tom qab tshuaj tsuag nrog dawb polyester xim.
Compatible with Lamination/Printing: The hot-dip galvanized surface can be coated with PVC film (to protect it from scratches during transportation) or screen-printed with logos (such as equipment nameplates). Cov nplaum ntawm ob qho kev ua kev lamination thiab luam ntawv ua tau raws li cov tseev kom muaj.
5.Qhov yog dab tsi yoog raws li cov nplaig thiab sib dhos ntawm cov hlau galvanized?
Bolted sib txuas: Drilled qhov tuaj yeem siv tau kom muaj kev ruaj ntseg nrog bolts. Lub zinc txheej yuav tsis tawg vim drilling, thiab zinc txheej nyob ib ncig ntawm lub qhov kub yuav tsum tau, yog tias yuav tsum tau tiv thaiv (siv anti {1} rust grease hauv lub qhov).
Piv txwv li, kub - dip galvanized thav duab ntawm cov bolts sab nraum zoov tuaj yeem sib dhos nrog rau nruab thiab xeb- ntawv pov thawj nyob rau lub sijhawm.
Riveted / clipped sib txuas: haum rau nyias, kub - dip galvanized standings (xws li cov cuab yeej siv hlau nplaum). Lub zinc txheej yuav tsis raug tsoo los ntawm rivets thaum riveting, thiab zinc txheej tuaj yeem tiv thaiv kev ntxhov siab ywj pheej thiab yuav tsis poob thaum lub sijhawm sib tsoo.
