1. Vim li cas Huab Cua Hlau Qhov Rooj Nyuaj Siab Yuav Tsum Muaj Patina tsis sib xws
Cov qauv sib txawv thiab cov npoo: Lub qhov rooj thav duab, pob khawm recesses, thiab vaj huam sib luag seams ntxiab ya raws thiab plua plav, ua rau oxidation sai dua thiab tsaus patina piv rau cov chaw tiaj tus.
Kev tsis sib xws: Qhov chaw ntawm qhov rooj ntsib tshav ntuj ncaj qha oxidize qeeb (xim sib dua), thaum ntxoov ntxoo sab los yog hauv qab ntug khaws cov dej noo ntev dua (xim tsaus dua).
Ua cov khoom seem: Cov roj stains los ntawm kev tsim khoom (xws li, vuam, stamping) lossis cov ntiv tes rau ntawm qhov chaw ua rau thaj tsam "stain xeb" nrog cov xim tsis zoo.
2. Core Measures los xyuas kom meej Uniform Patina Xim ntawm Weathering Steel Qhov Rooj
(1) Ua ntej-Kev tsim khoom: Standardize Surface Condition
Tag nrho - nto sandblasting: Kho tag nrho lub qhov rooj (xws li thav duab, npoo, thiab recesses) nrog nplua -grained aluminium oxide abrasive kom ua tiav ib qho roughness (Ra 3-5 μm). Qhov no tshem tawm cov nplai zeb, cov roj seem, thiab cov cim ua tiav, tshem tawm "pib qhov sib txawv" rau oxidation.
Tsis txhob muaj kev sib kis hauv zos: Siv cov hnab looj tes huv thaum sib dhos los tiv thaiv kev hloov pauv ntiv tes; so saum npoo nrog tus neeg sawv cev degreasing (piv txwv li, isopropyl cawv) ua ntej kho patina.
(2) Artificial Patina Acceleration: Txoj Kev Zoo Tshaj Plaws rau Qhov Rooj
Siv lub tshuab cua txias (piv txwv li, 2-5% ferric chloride + copper sulfate tov) sib npaug ntawm tag nrho lub qhov rooj siv lub tshuab nqus tsev siab tsawg - rab phom txau. Xyuas kom tag nrho cov npoo thiab qhov chaw so (tsis muaj qhov chaw tsis nco qab).
Muab lub qhov rooj tso rau hauv qhov av noo-chamber tswj (20–30°C, 70–90% RH) rau 3–5 hnub. Tig los yog hloov lub qhov rooj txhua hnub kom ntseeg tau tias txhua qhov chaw raug cuam tshuam rau ib puag ncig ib puag ncig.
Yaug lub qhov rooj kom huv si nrog dej huv kom tshem tawm cov ions accelerator seem, ces qhuav nws tag. Qhov tshwm sim yuav yog ib qho reddish -xim av patina hla lub tiaj tiaj, npoo, thiab thav ntawv.
(3) Ncej -Kev teeb tsa: Kev Kho Kom Zoo Kom Zoo
Siv pob tshab breathable sealant: Txheej tag nrho lub qhov rooj nrog fluorocarbon-raws li breathable sealant tom qab patina maturation. Qhov no cais cov patina los ntawm ib puag ncig tsis sib xws (piv txwv li, nag los nag, plua plav tsub zuj zuj) thiab xauv rau hauv cov xim sib xws rau 2-3 xyoos. Rov ua dua lub sealant txhua 2-3 xyoos kom tswj tau qhov sib xws.
Kev tu tsis tu ncua: Yaug lub qhov rooj nrog cov dej siab tsawg -txhua 6-12 lub hlis kom tshem tawm cov plua plav, cov noog poob, lossis lwm yam kab mob uas ua rau muaj xim tsis zoo. Tsis txhob siv cov tshuaj tua kab mob acidic lossis alkaline uas ua rau patina puas.
Optimize installation txoj hauj lwm: Tsis txhob mount lub qhov rooj nyob rau hauv cov cheeb tsam uas muaj dej tsis tu ncua (piv txwv li, nyob rau hauv eaves nrog dej tsis zoo) los yog ib tug - ib sab shading (piv txwv li, nruj tiv thaiv phab ntsa). Qhov no txo qis qhov sib txawv oxidation thaum lub sijhawm ua haujlwm ntev -.
