1. Cov khoom siv xaiv thiab qauv
Qeb Yuav Xaiv:
Xaiv cov qib nrog kev ua kom sov tiv thaiv kev tiv thaiv (piv txwv li,Q355NHRau GB / T 4171,ASTM A588rau Asmeskas, lossisS355J0WPer EN 10025-5).
Xyuas cov tshuaj muaj pes tsawg leeg tshuaj (CU, CR, P, NI) raws li cov qauv patina.
Tuab thiab lub zog:
Siv cov gauges thicker (piv txwv li, ntau dua lossis sib npaug nrog 4 hli) rau account rau cov muaj peev xwm ua kom haum yog tias xav tau.
Ua kom meej meej tawm lub zog (ntau dua los yog sib npaug rau 355 MPa rau Q355NH) ua kom haum nrog cua thauj thiab cov kev xav tau.
2. MATHINA tsim thiab kev tswj hwm kev zoo nkauj
Sib Xws Kev Loj Hlob:
Ua ntej - ecidize panelsArtificially (piv txwv li, tshuaj tsuag tshuaj lom neeg nrog cov tshuaj tsuag cuso₄) kom ua tiav cov xim zoo ib yam thiab tsis txhob ua kom nruj.
Sandblast Thaj Chaw(SA 2.5) Ua ntej kev teeb tsa kom tshem tawm cov zeb teev thiab xyuas kom muaj MATINATE nucleation.
Kev Tswj Xyuas Kev Kho Mob:
Tsim qauv txigthiabSLOping Surfaces(Ntau dua los yog sib npaug rau 3 degree) kom tiv thaiv xeb -} eg staining cov ntaub ntawv nyob ib sab (piv txwv li, qhob).
Yaug panels tsis tu ncuaNyob hauv thawj 6-12 lub hlis los ntxuav kom muaj xeb xoob xoob thiab muaj kuab paug.
3. Qauv qauv thiab kev sib txuas tsim
Thermal nthuav dav:
Haum kom haum lub zog cua (coefficient ~ 12 × 10⁻⁶ / degree) nrogSlotted bolt qhovthiab nthuav tawm pob qij txha.
Galvanic corrosion:
Colate cov huab cua hlaulos ntawm kev sib cais me me (piv txwv li, txhuas, hlau stainless) sivtsis - Conductive Gasketslos yog pleev xim los tiv thaiv cov tshuab hluav taws xob.
Fasteners thiab Welds:
Kev sivHuab Cua Hlau -} Tshaj Tawm Tau Txais Nyiaj Fasteners(piv txwv li, Astm A325 ntaus 3) thiabTsawg - hydrogen welve vuam Electrodestxhawm rau tswj hwm corrosion tsis kam ntawm kev sib txuas.
Zom cov velds dukom tsis txhob crevices uas ya raws tuaj yeem tsim tau.
4. Ib puag ncig kev hloov kho
Hars ib puag ncig:
Hauv ntug hiav txwv lossis chaw muaj kev lag luam, qhia meejsiab dua -} alloy cov qib(piv txwv li, q415nhc nrog nce ni / cr) lossis thovNtshiab Foob(piv txwv li, silane - raws) los thaiv chloride / so a.
Cov Lus Qhia Txog Cov Lus Qhia:
Zam kev ntxiab dej; sib xyawWeeks Qhovthiab tso kua dej raws qab qab panels.
5. Txij Nkawm thiab Saib Xyuas
Pib Saib Xyuas:
Soj ntsuam ib xyoos ib zaug raukev dailossistsis muaj xeb, tshwj xeeb tshaj yog nyob rau hauv crevices lossis pob qij txha.
Ntxuav:
Siv qis - qhov kev ntxuav dej ntxuav kom tshem tawm cov av thiab cov pa phem tsis muaj kev ua kom lub patina.
Kev kho:
Rau thaj chaw uas puas lawm, cov chaw - sandblast thiab re- ats ua kom nrawm kev kho mob.
