galvanized steel phaj
Nrhiav kev taw qhia ntawm kev ua DX51D + Z200 galvanized steel daim hlau? Koj nyob qhov twg lawm. Raws li lub Hoobkas ncaj qha nrog 20 xyoo dhau los, GNEE Steel muab cov kws tshaj lij cov lus qhia txog kev ua haujlwm nrogDX51D + Z200 galvanized steel phaj. Hauv phau ntawv qhia no, peb yuav qhia cov kev coj ua zoo tshaj plaws rau kev txiav, khoov, thiab vuam kom ntseeg tau tias cov txiaj ntsig zoo.
Galvanized steel phaj
DX51D + Z200 kev sib xyaw ua ke ntawm kev tsim kho siab thiab Z200 txheej yuav tsum tau ua cov txheej txheem tshwj xeeb. Kev tuav kom zoo khaws cov zinc txheej thiab tswj cov khoom siv tiv thaiv corrosion.
Kev ua tsis raug tuaj yeem ua rau cov txheej txheem puas tsuaj, ua rau xeb ntxov ntxov -tshwj xeeb yog qhov tseem ceeb rau kev siv sab nraum zoov uas DX51D + Z200 feem ntau siv.
Txiav Qhov Zoo Tshaj Plaws rau DX51D + Z200
Ua raws li cov lus qhia no thaum txiav DX51D + Z200:
- Txiav: Siv cov hniav ntse nrog 5-10% clearance txheeb ze rau cov khoom thickness kom tsis txhob txheej chipping.
- Laser Txiav: Khaws qhov nruab nrab ceev (3-5 m / min rau 1mm thickness) kom tiv thaiv zinc vaporization, uas tuaj yeem ua rau cov ntug txiav.
- Plasma Txiav: Siv cov amperage tsawg (60-80A rau 1-3mm thickness) thiab nqaim kerf kom txo tau qhov kub ntawm cov txheej.
- Kev kho ntug: Siv zinc- cov xim nplua nuj (Ntau dua lossis sib npaug ntawm 90% zinc cov ntsiab lus) rau txhua qhov txiav hauv 48 teev kom rov qab tiv thaiv corrosion.
- Cov cuab yeej tu: Cov cuab yeej huv tom qab siv los tshem tawm cov zinc seem, uas tuaj yeem cuam tshuam rau kev txiav txim siab lub sijhawm.
Cov kev coj ua no ua kom huv si tsis muaj kev cuam tshuam Z200 txheej.
Cov lus qhia khoov rau DX51D + Z200
Kev khoov kom zoo khaws cov txheej thiab cov khoom siv zoo:
| Thickness | Yam tsawg kawg nkaus Khoov Radius | Khoov kub | Ntsiab lus |
|---|---|---|---|
| 0.3mm-1.0 hli | 0.5 × thickness | Chav kub | Siv polyurethane tuag los tiv thaiv txheej khawb |
| 1.0mm-2.0 hli | 1 × thickness | Chav kub | Siv txawm siab kom tsis txhob muaj txheej txheej tawg |
| 2.0mm-3.0 hli | 1.5 × thickness | Chav kub | Ua ntej- cua sov rau 40-60℃yog khoov hauv qhov chaw txias |
Tsis txhob khoov ntawm qhov kub qis dua 0 degree, vim qhov no ua rau muaj kev pheej hmoo ntawm txheej brittleness thiab tawg.
Vuam Cov Lus Pom Zoo rau DX51D + Z200
Vuam xav tau kev saib xyuas tshwj xeeb los tiv thaiv zinc txheej:
- Txoj kev pom zoo: MIG vuam nrog silicon-bronze muab tub lim hlau (ERCuSi-A) kom zoo tshaj txheej txheej.
- Thaum tshav kub kub tswj: Siv cov khoom siv hluav taws xob tsawg (1-1.5 kJ / mm) kom txo cov zinc hlawv, uas ua rau cov pa taws thiab ua rau tsis muaj zog corrosion.
- Qhov cua: Ua kom muaj cua txaus kom tsis txhob muaj zinc fume inhalation, uas tuaj yeem ua rau muaj teeb meem kev noj qab haus huv.
- Ncej -Kev kho Weld: Ntxuav cov chaw weld nrog txhuam txhuam, tom qab ntawd siv zinc-nplua nuj primer thiab topcoat los tiv thaiv.
- Welder Qualification: Siv cov khoom siv vuam uas tau ntsib nrog cov hlau galvanized los xyuas kom zoo ib yam, siab - cov pob qij txha zoo.
Ua raws li cov kauj ruam no ua kom cov welds muaj zog thaum tswj cov khoom siv corrosion.
DX51D + Z200 galvanized steel phajtuaj yeem ua tau yooj yim nrog cov txheej txheem tsim nyog, khaws cia nws cov txheej txheem thiab kev ua haujlwm zoo. Ua raws li cov kev coj ua zoo tshaj plaws no ua kom koj cov khoom tiav tiav raws li cov qauv zoo thiab muaj lub neej ua haujlwm ntev.
Txhawm rau kom tau txais cov lus qhia ntxaws ntxaws lossis sib tham txog koj qhov project cov cai tshwj xeeb rau DX51D + Z200, thov tiv tauj peb pab neeg txhawb nqa tam sim no.Peb yuav muab cov lus qhia tus kheej los ua kom zoo rau koj cov txheej txheem tsim khoom.
