Electro - galvanized ntawv
Cov Qauv Txheej Txheem Kev Koom Tes: tsom mus rau "txheej tuab tuab," nws hais txog qhov kev sib txawv ntawm thickness thiab tag nrho cov kev pab them nqi.
Cov txheej txheem thoob ntiaj teb: ASTM A525 yuav tsum tau hais tias cov tuab sib txawv ntawm lub electriation yuav tsum tsis pub tsawg dua li lossis ib leeg {}}}} {muaj ntau dua lossis sib npaug rau 9μm). ISO 1461 muaj txawm tias cov tub txaij yuav tsum tau ua kev sib txawv ntawm electro {{} galvanized txheej (khib nyiab tsawg dua los yog sib npaug ntawm 5%).
Nyeg tsev: GB / T 13912 1}}}}}}}}}}} Txoj cai ntawm cov hluav taws xob thickness yuav tsum muaj ntau dua lossis sib npaug ntawm cov coeffiation coeffiation tsawg dua los yog sib npaug rau 10%.
2.What yog qhov yuav tsum tau ua rau txheej sib luag hauv cov chaw muaj kev sib xyaw ua kom haum (marine, tshuaj lom neeg)?
Cov Qauv Txuj Ci: Qhia txog qhov tsawg kawg hauv cheeb tsam tuab thiab cov nyiaj them rau saum npoo av.
Rau galvanized steel ntawv siv nyob rau hauv cov nkoj: ASTM A131 yuav tsum muaj kev sib txawv ntawm cov xim zinc me me ntawm tsawg dua lossis sib npaug ntawm 90% ntawm qhov chaw tuab los tiv thaiv "Ntug Corrosion."
Rau cov khoom siv tshuaj lom neeg: ISO 1461 yuav tsum muaj tsawg kawg nkaus cov thickness hauv kub - ntawm cov neeg muaj txiaj ntsig zoo tshaj plaws lossis sib npaug ntawm kev ntsuam xyuas kev tshuaj xyuas (tsawg dua lossis sib npaug nrog 5 ntsiab lus / dM²).
3.Qhov yog qhov yuav tsum tau rau Zinc Txheej kev sib dhos rau cov khoom muaj teeb meem siab (cov khoom siv hluav taws xob hauv tsev, sab nrauv sab nrauv)?
Cov Qauv Txuj Ci: tsom rau saum npoo roughness thiab zinc dang strangle uniformity.
Cov khoom siv hauv tsev: GB / T 2523 - ± 2020, thiab sib npaug ntawm cov kab ke sib luag
Automotive sab nrauv Panels: GM 9540P yuav tsum tau hais tias sab nrauv ntawm electro {} galvanized sheetiation yuav tsum yog tsawg dua los yog sib npaug ± 5% kom paub meej tias cov xim sib xws tom qab pleev xim.
4.What yog qhov yuav tsum tau ua rau txheej sib xyaw ua ke rau kev ua haujlwm siab (stamping, khoov)?
Cov Qauv Qauv: Xav Txog Zinc Txheej Adhesion thiab Dev Kev Lom Zem.
Galvanized Sheet rau sib sib zog nqus duab: AVEM A653 xav tau kub} wrend ntsuas (khoov thoothness yuav tsum tsawg dua lossis sib npaug ± 10%.
Corrugated Steel Sheet rau kev tsim kho: GB / T 2518-2019 STIPulates qhov kev sib tw luv nqi ntawm tsawg dua los yog sib npaug ntawm 9 hli) yuav tsum tau txheeb xyuas cov txheej txheem.
5.Txhua yuav xaiv cov qauv sib txawv rau cov txheej txheem sib txawv?
Kub - dip Galvanized Ntawv
Cov hau kev tseem ceeb: sib nqus cov kev ntsuas thickness (GB / T 4956) thiab qhov hnyav rau ib chav nyob rau cheeb tsam txoj kev (ISO {{3} {} {}}}}} {pointion tsawg kawg nkaus.
Kev Tshawb Fawb Kev Tshawb Fawb: Lub Tooj Sulfate Xeem (GB / T 26933) yog siv los xyuas cov plating uas ploj los yog thaj chaw nyias nyias.
Lub Txhab Hluav Taws Xob
Cov hau kev tseem ceeb: x {{{{{{} spe}} Tshav pluorescence spectrometry (XRF) thiab METALLAMPIC MENTERNIACY, tsom mus rau thickness sib txawv thiab microstructural uniformity.
Kev ntsuas kev ua pov thawj: khoov kuaj (GB / T 232) thiab daim kab xev peel (itm d3359) yog siv los xyuas cov khoom sib xyaw ua ke.
Siv galvanized ntawv
Cov hau kev tseem ceeb: kev ntsuas hluav taws xob me me (SEM) thiab siv hluav taws xob ntau ntxiv (eds) yog siv los txheeb xyuas cov kev faib tawm theem, tsom mus rau ntawm γ theem piv txwv thiab interface interity.
Kev pov thawj ntsuas: Kev kuaj ntsev (GB / T 10125) thiab kev sim ua kom sov (ISO 9227) yog siv los xyuas corrosion tiv thaiv tsis zoo.
