kub-dip galvanized steel DX52D
Kub-dip galvanized steel DX52D raws li tus qauv 10346 yog ib qho tseem ceeb ntawm cov txheej txheem tsim khoom niaj hnub no. Nrog rau cov khoom siv tooj 1.0918 (yav tas los 1.0350), cov hlau no muaj kev sib xyaw ua ke zoo tshaj plaws ntawm kev ua kom txias txias thiab muaj zog tiv thaiv corrosion. Kev faib tawm raws li qib kev kos duab qhia txog nws qhov tshwj xeeb tsim nyog rau kev xav tau cov txheej txheem txias txias uas yuav tsum muaj qhov sib npaug ntawm kev tsim thiab lub zog siv tshuab.
Raws li ib feem ntawm cov txheej txheem galvanizing, kev tiv thaiv zinc txheej yog siv rau cov hlau nto kom muab cov khoom siv nrog kev tiv thaiv ib puag ncig. Ntxiv rau cov txheej txheem + Z txheej, cov neeg siv tuaj yeem xaiv los ntawm lwm cov txheej txheem tshwj xeeb xws li + ZF, + ZA, + ZM, + AZ thiab + AS. Cov kev hloov pauv no tso cai rau cov hlau kom haum rau qhov kev thov ntawm cov xwm txheej. Nyob ntawm cov txheej txheej xaiv, qhov roughness ntawm qhov chaw tuaj yeem ua kom zoo lossis ntxiv kev tiv thaiv kev tawm tsam tshuaj lom neeg tuaj yeem lav, piv txwv li, ua DX52D steel yog cov khoom siv tau yooj yim heev rau kev siv.

Cov tsos ntawm txheej yog ci, ceev faj, tsis muaj sagging los yog wrinkles. Kev tshuaj xyuas thickness tuaj yeem siv txheej thickness ntsuas, txoj kev yog qhov yooj yim. Lub thickness ntawm txheej kuj tuaj yeem tau los ntawm kev hloov cov nyiaj zinc adhesion. Rau lub zog sib txuas, lub xovxwm dabtsi yog khoov tuaj yeem siv los khoov tus qauv ntawm 90-180 degree, thiab yuav tsum tsis muaj qhov tawg lossis tawg ntawm txheej. Ib lub rauj hnyav kuj tuaj yeem siv los kuaj, thiab kev kuaj ntsev ntsev thiab tooj liab sulfate corrosion tuaj yeem ua tiav hauv cov khoom siv.
