1.What yog cov tub ntxhais tseem ceeb teeb meem hauv cov khoom raw thiab pretreatment?
Tsis txaus sawb sab saum npoo huv. Cov tsos mob: Residual Roj, nplai, cov kua hlau hlau, lossis cov kua dej tsis ua haujlwm (zinc
Pluag sawb puab
Cov teeb meem tshwm sim: Lub Sawb cov khoom ua yeeb yam laim ntoom, thiab cov duab kos duab, ua rau muaj kev sib tiv tauj ntawm cov sawb thiab zinc daws thaum Galvanizing. Qhov no tuaj yeem ua rau muaj kev sib txawv loj hauv coating thickness (dhau ntawm cov npoo lossis nyias nyias nyob rau hauv nruab nrab), thiab muaj peev xwm ua rau cov khoom siv jamming thiab sawb breakage.
2.Qhov dab tsi yog cov txheej txheem core ntawm cov txheej txheem galvanizing?
Kub-DIP galvanizing ib txheej txheej los ntawm kev raus cov sawb rau hauv Molten Dinc ua kua (450-460 degree). Lub ntsiab lus kev tsis sib thooj yog qhov txuam ntawm cov zinc cov kua muaj ntau yam, ntsuas kub thiab seev cev.
3.Qhov dab tsi yog cov tub ntxhais cov teeb meem ntawm cov txheej txheem electrogalvanizing?
Cov txheej txheem txheej tsis zoo thiab cov pinholes
Cov tsos mob: tsis sib xws thickness (tuab ntawm cov npoo, nyias nyob rau hauv nruab nrab) lossis pinholes (me me) tshwm sim ntawm sawb sab, cuam tshuam rau cov nplaim thiab corrosion tsis kam.
Tsis txaus txheej txheej nplaum
Cov tsos mob tshwm sim: txheej peeling ("peeling") thaum lub sij hawm khoov lossis hydrogen eSretures (hydrogen eatritate thaum lub sij hawm ua yeeb yam (ua tsis tiav ntawm cov txheej txheem ntawm cov txheej txheem ntawm cov txheej txheem ntawm substrate).
4.Qhov dab tsi yog cov teeb meem tseem ceeb hauv kev ua haujlwm tom qab ua haujlwm?
Passivation zaj duab xis tsis ua hauj lwm
Cov teeb meem tshwm sim: passivation cov yeeb yaj kiab (xws li chromate passivation thiab solomium-free corrosion (ntxov corrosion dawb)
Uneven roj daim ntawv thov lossis paug
Cov tsos mob tshwm sim: xeb-pov thawj roj (xws li nyuaj zaj duab xis lossis roj tsis muaj xeb (xws li cov hmoov av hauv av) tau sib xyaw, ua rau muaj cov hlau).
5.Qhov qhov teeb meem tseem ceeb ntawm kev ua haujlwm zoo thiab tus nqi tswj tau?
Kev ntsuas nrawm nrawm thiab zoo: nce sawb ceev tuaj yeem ua rau muaj peev xwm ua tau ntau yam (tsis muaj peev xwm ua tiav lub sijhawm (tsis ua tiav); tsis ncaj txias ntawm cov galvanized txheej ("zinc txaus cim"); thiab kho tsis txaus ntawm cov yeeb yaj kiab tom qab kev kho mob.
Kev daws: Cov khoom siv txhim kho kom tau raws li cov txheej txheem uas yuav tsum tau ua dua ntawm kev ceev.
Zinc tau thiab khib nyiab tswj
Kev noj ntau dua zinc tau ncaj qha rau cov nqi nce ncaj qha, feem ntau vim yog: ntau dhau thoj tsho me me; Ntau dhau los zinc lub lauj kaub slag (ntau dhau cov hlau cov ntsiab lus hauv da dej thiab sawb breakage ua rau zinc da dej da dej.
Cov ntsiab lus tswj hwm: Txhim kho cov neeg muaj pa taws kom txo tau cov txheej ntau; Txo zinc slag los ntawm online zinc da dej tsom xam; Thiab txhim kho cov cuab yeej ruaj khov kom txo cov txaij breakage.
