1. Txoj kev tshem tawm xeb (zoo & nyab xeeb rau Q235NH)
Mechanical xeb tshem tawm
Hlau txhuam / fais fab sib tsooTshem tawm xoob nto xeb; yooj yim thiab tsawg - nqi.
Sandblasting / txhaj tshuaj blasting(zoo tshaj plaws rau cov khoom siv hauv tsev) Cleans rau liab qab hlau, tsim ib tug ntxhib nto rau zoo txheej adhesion.Suitable rau signage, paj thawv, steel lug.
Siab -lub dav hlau dej siab tuTshem tawm cov xeb xoob yam tsis muaj kev puas tsuaj rau lub hauv paus hlau.
Tshuaj tshem tawm xeb
Rust converter (phosphoric acid-raws li)Converts xoob xeb mus rau hauv ib tug ruaj khov dub txheej tiv thaiv.Zoo rau nyias xeb; tuaj yeem pleev xim ncaj qha.
Mild rust removerTsis txhob muaj zog hydrochloric acid - nws yuav ua rau dhau -corrosion ntawm Q235NH.
Lub hom phiaj: Tshem tawmtag nrho cov xoob, powdery xeb; khaws cia nruj, ruaj khov oxide yog tias tam sim no.
2. Txoj kev tiv thaiv tom qab tshem tawm xeb
Txij li Q235NH yoglow-qeb huab cua steel, nwstsis tuaj yeem ntseeg tus kheej - tiv thaivnyob rau hauv hnyav lossis tsis yog - huab cua ib puag ncig.
Kev xaiv A: Rov ua dua nrog cov tshuaj tiv thaiv- cov xim pleev xim (feem ntau txhim khu kev qha)
Thovepoxy zinc -nplua nuj primerlos yogepoxy primer
Ntxivpolyurethane topcoatlos yogalkyd enamel
Muab kev tiv thaiv tag nrho ntawm dej, av, chiv, ntsev, av noo.
Yuav tsum siv raupaj thawv sab hauv phab ntsa, faus qhov chaw, ntug hiav txwv dej.
Kev xaiv B: Re- daim ntawv ruaj khov patina (tsuas yog rau qhov chaw sab nraum zoov)
Tshem tawm cov xeb xoob, kom nruj oxide.
Khaws qhov chawqhuav thiab ventilatednrog nquag ntub- voj voog qhuav.
Tso cai rau rov xeb ib txwm los tsim ib qho tshiab patina.
Tsuas yog ua haujlwm rausab nraum zoov, zoo-ventilated, tsis-chaw nyob.
Kev xaiv C: Siv cov sealer ntshiab
Tom qab tsim patina ruaj khov, tshuaj tsuagacrylic los yog polyurethane clear coat
Locks xim, tiv thaiv xeb tawm, nres ntxiv corrosion.
3. Cov Lus Qhia Tseem Ceeb rau Q235NH
Yog sivnyob rau hauv av, dej, paj thawv, los yog ntug hiav txwv dej: Yuav tsum sivtxheej txheej tag nrho- patina ib leeg tsis txaus.
Yog sivsab nraum zoov qhib cua: tuaj yeem rov tsim patina, tab sis kev tshem tawm xeb yuav tsum ua kom tiav.
Welded cheeb tsam yog nquag rov xeb: yuav tsum tau prime thiab seal tom qab xeb tshem tawm.
