1. Pickling & Passivation
Cov nyhuv tseem ceeb: Tshem tawm cov kub- dov oxide nplai, nto xeb thiab roj stains; ua ib zaj duab xis nyias nyias ntawm cov hlau nto rau inhibit qhov pib oxidation thaum khaws cia / thauj.
Txheej txheem: Acid pickling (sulfuric/hydrochloric acid) → dej ntxuav → neutralization → passivation (chromate/non{0}}chromate tov) → ziab.
Daim ntawv thov: Ua ntej-kev kho mob rau kev ua haujlwm tom ntej (slitting, sib sau, txheej); haum rau coils yuav tsum fabricated rau hauv panels, cladding thiab structural qhov chaw, kom ib tug huv puag saum npoo rau uniform patina tsim.
2. Ua ntej-Kev kho huab cua (Controlled Oxidation)
Cov nyhuv tseem ceeb: Hoobkas-induced tswj sab nraum zoov/accelerated oxidation los ua ibpreliminary ntom, uniform patinantawm lub coil nto; tshem tawm ntawm - qhov chaw xeb hmoov los ntawm qhov chaw thiab ua kom lub sijhawm ntev patina sab nraum zoov los ntawm 12-24 lub hlis mus rau 1-3 lub hlis.
Txheej txheem: Simulated sab nraum zoov cov av noo / kub raug → nto hloov kho → ntuj oxidation los tsim ib lub hauv paus ruaj khov patina → nto sealing (yeem).
Daim ntawv thov: Coils rau architectural decorative khoom (facades, signboards, sculptures); zoo tagnrho rau tej yaam num uas yuav tsum tau tam sim uniform xeb aesthetics yam tsis tau pib staining.
3. Transparent Weathering Sealer Txheej
Cov nyhuv tseem ceeb: Siv lub nyias nyias, breathable pob tshab polymer sealer (dej-raws li / hnyav-raws li) rau lub coil nto; ntxiab xoob xeb hmoov nyob rau hauv thawj theem oxidation, accelerates patina uniformity thiab tsis thaiv ntuj patina kev loj hlob.
Txheej txheem: Nto tu → cov menyuam txheej ntawm sealer (thickness: 5–20 μm) → qis -kub curing (80–120℃).
Daim ntawv thov: Coils rau lub tsev cladding, curtain phab ntsa thiab sab nraum zoov rooj tog; tiv thaiv xeb hmoov staining ntawm cov ntaub ntawv uas nyob ib sab thiab tuav tus thawj steel zoo nkauj.
4. Kev Txhaum Txhaum Cai / Xuab zeb Blasting
Cov nyhuv tseem ceeb: Tshem tawm nplai, xeb thiab nto burrs ntawm siab -kev cuam tshuam ceev ceev; tsim ib qho matte / ntxhib xim hlau nto zoo nkauj thiab txhim kho cov adhesion ntawm cov txheej tom ntej (yog tias siv).
Txheej txheem: Qhuav txhaj / xuab zeb blasting → plua plav tshem tawm → ntxuav nto.
Daim ntawv thov: Coils rau kev cai fabrication (sculptures, toj roob hauv pes qauv) los yog coils yuav coated nrog anti-corrosion primers; qhov ntxhib nto txhim khu kev sib txuas nrog cov txheej txheem los yog pob zeb.
5. Roj Txheej (Anti-Xeb Roj)
Cov nyhuv tseem ceeb: Siv cov yeeb yaj kiab nyias nyias ntawm volatile/non-volatile anti- xeb roj rau lub coil nto; ua rau lub cev tiv thaiv kom tsis txhob muaj huab cua thiab noo noo, tiv thaiv xeb thaum lub sij hawm ntev - lub sij hawm cia (6-12 lub hlis) thiab kev thauj mus los hauv hiav txwv.
Txheej txheem: Degreasing degreasing → cov menyuam txheej los tiv thaiv - xeb roj (thin film) → winding thiab ntim.
Daim ntawv thov: Unprocessed coils ntev - cov khoom muag lossis kev xa khoom thoob ntiaj teb; cov roj txheej tau yooj yim tshem tawm los ntawm degreasing ua ntej tom ntej fabrication / installation.
6. Slit Edge kho
Cov nyhuv tseem ceeb: Targeted kev kho mob rau coil slitting npoo (ntse, unprocessed npoo muaj micro-corrosion); tshem tawm ntug burrs thiab tsim cov txheej txheem tiv thaiv kom tsis txhob pib ntug rusting.
Txheej txheem: Ntug deburring → ntug passivation / lub teeb txheej ntawm sealer → ziab.
Daim ntawv thov: Slitted coils rau vaj huam sib luag / trim fabrication; ib qho kev pab cuam kho kom haum rau tag nrho - cov coils kho saum npoo kom ntseeg tau tias tag nrho cov corrosion kuj.
7. Electrostatic Powder Coating (Optional Functional Coating)
Cov nyhuv tseem ceeb: Siv cov xim pleev xim / pob tshab hmoov txheej rau lub coil nto rau kev txhim kho corrosion nyob rau hauv ib puag ncig hnyav (siab ntsev tsuag, muaj kua qaub pos huab); cov txheej yog hnav-tiv taus thiab khawb- pov thawj.
Txheej txheem: Nto ua ntej-kev kho mob (pickling/shot blasting) → electrostatic hmoov txau → siab- kub curing (180-200℃).
Nco tseg: Blocks ntuj tsim patina; tsuas yog rau tej yaam num tseem ceeb tshaj qhov kev tiv thaiv corrosion tshaj lub hauv paus weathering steel xeb aesthetic.
