Mipela i bin salim Corten steel i go long ol projek long olgeta hap bilong wol. Maski yu go long ol drai ples drai bilong Midel Is o ol ples hat bilong Saut-is Esia we i gat planti wara, ol klaien bilong mipela i save askim wankain askim oltaim:"Bai Corten steel i stap laip long klaimet bilong mi?"
Sotpela bekim em yes. Tasol trupela samting long graun em olsem, 'weathering steel' i no save wok wankain long olgeta hap. Ol ples drai na ol ples hat i save putim ol ain long ol narapela kain kondisen, na sapos yu no stretim ol samting yu makim long envairomen, bai yu senisim ol komponen hariap na westim mani bilong projek.
Sikret bilong mekim invesmen bilong yu i stap longpela taim em long kliagut long hau 'protective patina' bilong en i save kamap. Yumi lukluk long wanem samtingi save kamap tru long dispela samting long ol ples we i gat bikpela san na wanem samting ol impota na ol projek menesa i mas save long en.
Ol Mekaniks bilong Patina (Bilong Wanem Klaimet i Bikpela Samting)
Yumi kisimwanpela samting stret: Corten em i no ain tasol we i save ros. Strongpela bilong en i dipen long patina-wanpela strongpela, wara i no inap go insait long en we i save kamap taim ain i wok wantaim oksijen na wara. Taim ol i kamap pinis, dispela leit i save stopim gut moa korosen long ol rot bilong en.
Tasol, sapos ain i no kisim stretpela miks bilong dispela tupela samting, patina bai no inap kamap gut. Sapos i no gat gutpela 'patina', Corten bai bagarap hariap wankain olsem standet 'carbon steel'. Ol ples drai na ol ples hat i gat planti samting tru na narapela samting i sot tru,dispela em i as tru na ol samting i save wok long narapela narapela rijon.
Corten insait long ol ples wesan (Hat, Drai, na Abrasive)
Klaimet bilong ples draii gat bikpela hat tru, win i drai tru, bikpela senis long temperaja (kirap long 40 digri i go inap long kolpela nait), na ol wesan i save bruktorms. Long ol 'weathering steel', nambawan salens em i sot long wara we i nidim long kamapim 'patina'.
Pefomens Brekdaun
Long ples we i drailong ol ples olsem Saudi Arabia o Sahara, patina i save kamap hariap tru, na i save kisim 12 i go inap 18 mun taim yumi skelim wantaim 6 i go inap 12 mun long ol ples we i no hat tumas. Long namba wan yia, ain bai soim ol liklik hap, 'flaky rust', we em i 'standard corrosion' na i no 'stable patina'.
Tasol, taim em i kamap (planti taim bihain long ren i no save kamap planti taim o 'morning dew'), 'patina' i save kamap gutpela tru. Bikos i no gat ol sol o ol samting nogut i stap long win, mak bilong korosen i save go daun long mak bilong 0.01 i go inap 0.02 mm long wan wan yia. Long skelim, ol 'uncoated regular steel' long wankain kondisen inap long 'rust' insait long 3 i go inap 5-pela yia.
Seknarapela birua em wesan. Ol 'sandstorm' i save wok olsem wanpela 'abrasive blast', na i save kamapim ol liklik '-'scratch we i save soim ol nupela ain long draipela win.
Ol Gutpela Pasin Bilong Enjiniaring Long Ol Desert
- Makim Corttpi Bbilong ol straksa:Yusim Corten B long ol 'load-bearing components. Bikpela strong bilong en (550-830 MPa) i no inap bruk long taim bilong bikpela senis long tempereja.
- Mekim Patina i go hariap:Putim wara long ain long olgeta wik insait long namba wan 2 o 3 mun bilong kirapim kemikel riaksen.Factory Pre-Rusted Sevishia olsem wanpela rot bilong sevim taim-.
- Noken putim ol tikpela koting:Ol tikpela peint bai pasim win long 'patina'. Yusim wanpela liklik, gutpela 'rust-inhibiting primer bilong tatsim-aps agensim 'sand abrasion'.
- Gutpela Tiknes:Makim wanpela 6-8 mm 'thickness' bilong ol hap bilong haus na 4 mm bilong ol 'decorative cladding' bilong karim 'thermal expansion'sion.
Corten insait long ol ples hat (hat, wet, na sol)
Tropikal klaimets i save givim bikpela hat (30-35 digri), bikpela humiditi, bikpela ren, na, long ol ples klostu long nambis, sol i stap long win. Long hia, salens em i wanpela ekses of wara na ol 'chloride' we i save bagarapim ol samting.
Pefomens Brekdaun
Long ol ples hat, ol patina i save kamap hariap, planti taim insait long 3 i go inap 6-pela mun bikos wara i stap oltaim. Insait long ol ples hat we i no gat sol, mak bilong korosen i stap wankain long 0.02-0.03 mm long wan wan yia.
Tasol, ol tropikel eria klostu long nambis i save pait nogut tru. Sol sprei i save pas long ain na i save brukim 'patina'. Olsem, Corten A we ol i yusim long wanpela pes long nambis long Thailand i bin bruk na bagarap insait long 5-pela yia. Na tu, oltaim humidity inap long kamapim'mold', tasol dispela inap long rausim isi na i no bagarapim ain.
Ol Gutpela Pasin Bilong Enjiniaring Long Ol Tropik
- Ol samting bilong nambisCorten B:Corten B em i mas stap long ol ples klostu long nambis. Bikpela silikon insait long en (0.25-0.50%) i givim gutpela strong long sakim sol sprei taim yumi skelim wantaim Corten A, we ol i mas yusim long bilasim haus insait long kantri.
- Silim olgeta arere:Ol arere we ol i no pasim i larim solwara na humiditi i go insait na bagarapim ain insait long en. Oltaim putim wanpela 'marine-grade sealant long ol arere we i stap ples klia.
- Mekim Tiknes bilong ol Samting i go antap: Yu mas makim 8 mm o moabilong ol samting bilong straksa long nambis na 6 mm bilong wok bilong straksa insait long kantri long mekim gutpela wok bilong as bilong en.
- Sekim na lukimDrenej:Disainim ol straksa bilong stopim wara i sanap. Puddling bai kamapim 'localized corrosion', na i abrusim proteksen bilong 'patina'.
