1.What yog qhov yuav tsum tau ua rau txheej tuab tuab?
Kev ntsuas txuj kev: sib nqus thickness ntsuas (tsis yog-rhuav tshem, thawj txoj kev).
Yam tsawg kawg nkaus yuav tsum muaj: Yam tsawg kawg hauv zos thickness thiab tsawg kawg qhov nruab nrab tuab yog teev raws li cov txheej tuab (Δ).
Tseem ceeb:
Cov tuab tuab ntawm cov txheej ncaj qha txiav txim ncaj qha rau lub neej tiv thaiv corrosion thiab yog cov tseem ceeb nyuaj ntawm kev lees txais.
→ Cov txheej txheem tseem ceeb ntawm cov tuam tsev siab (xws li kab teeb thiab kab) feem ntau yuav tsum Δ thiab sib npaug zos ntau dua lossis sib npaug rau 85μm yog ib qho yuav tsum tau ua.
2.What yog qhov yuav tsum tau ua rau txheej adhation zog?
Txoj kev xeem:
Rauj txoj kev: Ntaus lub txheej nrog rab rauj kom pom tias nws yog peels tawm (zoo).
Daim phiaj / kos txoj kev: kos ib daim phiaj lossis kab ncaj nraim nrog rab riam, thiab cov txheej tsis poob tom qab daim kab xev yog ntuag.
Dabtsi yog khoov xeem: Tom qab cov hnoos qeev yog bent 180℃yuav tsum tsis txhob tev tawm (tsuas yog siv rau cov khoom siv los ntawm cov khoom siv).
Yuav tsum muaj:
Cov txheej txheej tau sib raug zoo rau cov hlau hauv paus yam tsis muaj qhov muag lossis qhuav.
→ Kev tsim lub zog siab muaj kev cuam tshuam yooj yim thaum lub sijhawm thauj mus los thiab kev teeb tsa thiab tsis txaus ua rau corrosion tsis ua hauj lwm.
3.Qhov twg yog qhov yuav tsum tau ua rau cov tsos zoo?
Kev sib txuam: cov txheej txuas txuas ntxiv thiab ua tiav, npog tag nrho cov chaw (suav nrog cov ces kaum sab hauv thiab lub qhov ntsa.
Cov xwm txheej nto: Cov cim txaus me me thiab xim txawv me ntsis raug tso cai;
Tsis pub:
Mis-plating (cov hlau raug)
Burrs, Zinc Nodules (cuam tshuam rau Bolt kev twb kev txuas lossis teeb tsa)
Cov hlwv, tev, tawg
Residual Zinc Slag (cuam tshuam rau kev sib txhuam coefficient ntawm qhov kev tiv tauj saum npoo av)
Tshwj xeeb yuav tsum muaj rau cov tsev siab:
Cov khoom siv nthuav dav (xws li kab hlau rhuav Phab Ntsa Keels) yuav tsum tswj hwm cov cim txaus thiab xim sib txawv kom tau raws li kev xav tau kev ua kom zoo nkauj.
Cov kev sib txuas saum npoo ntawm kev sib txhuam-zog high-lub zog bolts yuav tsum pub dawb ntawm zinc nodules thiab burrs, lwm yam ntxiv yuav tsum muaj.
4.Qhov dab tsi yog cov kev xav tau ntawm cov nyom?
Muaj cov khoom siv: cov hlau hlau xaim, qhov chaw me me, thiab lwm yam.
Txoj kev xeem: Cov qauv yog raus hauv tooj liab sulfate daws (4 feeb txhua lub sijhawm), thiab cov txheej yuav tsum tsis muaj liab nws yog xim hlau bigition.
Rau kev tsim cov qauv txheej txheem, cov tuab tuab thiab muaj kev txhawj xeeb ntau dua, yog li cov qauv no tsis tshua siv.
5.Qhov twg yog qhov yuav tsum ua rau lub substrate?
Nto Pretreatment:
Ua ntej Galvanizing, roj stains, xeb, nplai, thiab vuam slag yuav tsum tau muab tshem tawm kom meej (los ntawm kev xaiv thiab plating tus neeg sawv cev).
Tus Weld yuav tsum tau polished thiab smoothed, txwv tsis pub nws yooj yim rau kev ua txhaum lossis tsis sib xws plating.
Plating muaj peev xwm:
Siab silicon steel tej zaum yuav tsim cov txheej txheem ua haujlwm ultra-tuab tab sis yog nkig thiab yuav tsum muaj cov txheej txheem tswj.
Txias-dov qhov chaw yuav tsum tau zam qhov "Sanderin nyhuv" (npaub txheej thiab cov nplaum tsis zoo).
