1. Ua kom ntseeg tau tias cov ntaub ntawv tsim nyog thiab tsim khoom
Paub meej tias cov ntsiab lus alloy: Txheeb xyuas tias cov hlau sib ntsib EN 10025-5-5 yuav tsum muaj, nrog cov ntsiab lus tseem ceeb nyob rau hauv cov lus teev tseg:
Cu: 0.25-0.55% (tseem ceeb rau Patina Densification),
CR: 0.30-0.80% (txhim kho kom ruaj khov),
P: 0.07-0.15% (txhawb nqa cov xeb sib txawv),
MN: Tsawg dua lossis sib npaug nrog 1.60%, C: Tsawg dua lossis sib npaug lossis sib npaug ntawm 0.12% (tiv thaiv kev cuam tshuam loj uas cuam tshuam patina).
Zam kom tsis txhob muaj kev paug rau thaum lub sijhawm tsim khoom: Ua kom cov steel yog pub dawb los ntawm cov roj, roj, lossis tiv thaiv cov txheej txheem tiv thaiv (piv txwv li, waxes) uas thaiv oxidation. Zeb nplai (ib qho pib nyias oxide) yog tau txais tab sis yuav tsum tsis txhob muaj tuab heev, raws li nws tuaj yeem ncua ntev pata tsim.
2. Tswj kev npaj nto thiab kev ua tiav
Kho cov txiav / txheej txheem sawv: Raws li tau sib tham ua ntej lawm, cov ntoo huv nrog cov hlau txhuam lossis cov xuab zeb kom tshem cov burrs thiab xoob xoob. Thov ib qho patina accelerator (piv txwv li, cov tswv lag luam corten presen presters) rau cov chaw no kom phim lub PATINA tsim tus nqi ntawm daim qub.
Tswj Welds: Cov khoom siv tshuaj feem ntau muaj cov sib txawv sib txawv (vim yog cov tub lim hlau) thiab tuaj yeem tsim cov xeb tsis sib xws. Post {- Kev Kho Weld muaj xws li:
Sib tsoo kom du weld hlaws dai,
Thov ib lub patina acceler rau hauv thaj chaw weld,
Zam kev "Tshaj - {Vuam," Qhov twg tuaj yeem tsim cua sov- cuam tshuam rau micrutructure uas tiv taus kom tsim nyog patina.
3. Txhim kho ib puag ncig ib puag ncig
Xyuas kom muaj cyclic noo: Cov hlau xav tau kev ntub dej tsis tu ncua (nag, lwg) ua raws li kev ziab kom tsav oxidation. Nyob rau hauv cov huab cua qhuav, lub sijhawm ua yuam kev (nrog cov dej huv) tuaj yeem simulate lub voj voog no, ua kom nrawm patina tsim.
Txo cov ntsev thiab cov kuab paug:
In coastal areas (<=3 km from the sea) or regions with de-icing salts, apply a salt-resistant sealant (eg, silane-based coatings) to slow chloride penetration until the patina matures.
Hauv cov cheeb tsam muaj kev muaj zog (siab dua los yog hmoov av), yaug lub quarterly nrog cov dej huv kom tshem tawm cov acidic tso nyiaj uas yaj lub patina.
Txhawb nqa airflow: Xyuas kom cov steel yog ntsia nrog cov khoob (piv txwv li, ntawm cov vaj huam sib luag) los tiv thaiv cov dej noo hauv noo noo. Zam txhob npog nrog tsis - breathable cov khoom (yas, yas,, cua ua rau xeb tsis sib xws.
4. Saib xyuas thiab tswj lub sijhawm patina tsim
Soj ntsuam tsis tu ncua: Kos rau cov cim ntawmtsis zoo xeb(xws li, xoob, powderery txiv kab ntxwv xeb; pitting; los yog tsis sib xws). Cov no qhia tias:
Cuab noo noo (txhim kho nrog cov kua dej zoo dua / Airflow),
Paug (huv si nrog dej lossis hnoos qeev kom me),
Alloy Deficiency (tsis tshua muaj, tab sis cov khoom siv pov thawj tseeb yog tias muaj teeb meem thev naus laus zis).
Zam kev ua kom huv siav: Tsis txhob siv fais fab - ntxuav lossis txhuam qhov saum npoo hauv thawj 6 lub hlis, vim qhov no tshem tawm cov neeg muaj nuj nqis patina. Tom qab 6 lub hlis, maj mam txhuam tawm ntawm cov xeb xoob los ua cov txheej denser hauv qab.
Chaw daws teeb meem hauv zos: Yog tias thaj chaw me me tsis ua tiav daim duab patina ruaj khov,} Khib tawj nrog Patina Accelerator thiab xyuas kom thaj chaw tau ua kom muaj dej noo / ziab mus.
5. Ntev -} kev tiv thaiv
Zam kev ua kom huv: Siv tsuas yog qis - qhov siab dej yaug tshem tawm cov av; Cov tshuaj hnyav (acids, muaj zog dumperents) yuav yaj lub patina.
Tshawb xyuas txhua 2-3 xyoos: Khij rau cov kab nrib pleb lossis thinning nyob rau hauv lub patina (sib xws hauv high - kev nyuaj siab thaj chaw lossis huab cua siab tshaj). Kov nrog nrawm yog xav tau.
