1.What yog cov kev ntsuas los tiv thaiv deformation ntawm galvanized steel ua?
Ua kom zoo dua cov kab thiab txheej txheem
Laser / Ntshav Txiav: Siv cov ntsiab lus me me sib txuas los tiv thaiv cov hnab me me los ntawm kev poob thiab deforming.
Ntxiv kev ntxhov siab nyem cov grooves (dav ntau dua los yog sib npaug rau 2 zaug tuab ntawm lub phaj) thaum cov chaw ua zes.
Punching: Cov pwm sib zog yog tswj hwm ntawm 8% ~ 12% ntawm lub phaj tuab.
Kev hloov kho cov txheej txheem
Pwm Tsim Tsim: qis dua pwm V-lub qhov ncauj dav=6 ~ 8 zaug cov khoom tuab.
Sab saum toj pwm R kaum sab xis=phaj tuab × 1.2.
Tiv thaiv Zinc Txheej: Pwm yog lub zog chrome nyuaj rau kev sib txhuam
Siv cov yeeb yaj kiab PE los tiv thaiv khawb
2.Yog li cas cov hau kev rau kev kho kom raug?
Neeg Kho Tshuab Kho Lus
Cov Menyuam Txoj Kev Luas: Cov Phaj Nyias (0.5 ~ 3 hli) Wave Deformation
Cov menyuam spacing ≈ phaj thickness × 20, Ntau-dhau kev nce qib theem
HYDRAULIC SAPING: XUB PHAJ (> 4mm) siv ib qho xovxwm ntawm ntau tshaj 200t, nrog ib qho peb-seem hloov tau pwm
Zos Cua Sov Kho Zos
Flue Kho Neeg: Oxyacetylene Neutral Nplaim (kub tsawg dua lossis sib npaug nrog 250 degree)
Daim duab peb sab cua sov txoj kev: sab ntev 30 ~ 50mm, luv 100 hli
Kev co kev ntxhov siab nyem (VSR)
Muaj feem rau loj welded cov txheej txheem
Zaus heev ntau: 50 ~ 150Hz, amplitude 0.5 ~ 1 hli, lub sijhawm kho 10 ~ 20 feeb
3.Yog li cas los daws cov xwm txheej tshwj xeeb?
Drilling / Tapping deformation:
Kev daws: Ua Ntej-Ntaus Lub Qhov Tshawb Ntsuam Xyuas Kev Tshawb Xyuas (Qhov Lub cheeb= 60}% ntawm lub qhov kawg); Coated tho (tialn) ceev ↓ 30%, pub ↑ 20%; Txau cov dej ua kua dej ua kua dej (chlorine txwv tsis pub).
Cov txheej txheem saw optimization: Pre-wirftinging quab yuam=120}% ntawm kev tawm tsam zaum kawg
Kev Kho Mob Laus: Ci ntawm 80 Degree rau 2 teev tso tawm kev ntxhov siab
4.Qhov dab tsi yog cov ntsiab lus tseem ceeb ntawm Zinc Txheej Kev Tiv Thaiv?
Qhov kub liab kab: Ua thaj chaw kub<150℃ (to prevent zinc from oxidizing and turning black)
When the welding heat affected zone is >300 degree, siv zinc kho cov xim (muaj 96% zinc hmoov)
Kev Tiv Thaiv Nto: Tsuag Epoxy Zinc-Rich Primer (80μm) tsis pub dhau 48 teev tom qab ua
5.Qhov cov kev txiav txim siab tseem ceeb?
Tsis txhob rauj lub zinc txheej: nws yuav ua rau cov txheej zinc ib qho los tev tawm thiab poob nws txoj kev corrosion.
Kev kho mob tom qab ntawm thermal kho: so cov cua sov nrog 10% citric acid daws teeb meem kom tshem zinc oxide tshauv
Rov txau zinc tsuag (xws li Zrc txias galvanizing)
Kuaj Cov Qauv: Flats tsawg dua los yog sib npaug rau 1 hli / m²; Zinc Txheej Ua Kom Puas<5%.
