Thaum PaintingQ550NHERING STEEL, nto tshwm sim yuav tsum ua tib zoo sib npaugCorrosion tiv thaivthiabXim nplaumThaum khaws cov hlau cov cua sov uas muaj cov cua sov (yog tias xav tau). Ntawm no yog cov yuav tsum tau ua:
1. Sandblasting (Abrasive Tu)
Lub hom phiaj: Ua tiavSA 2.5(ISO 8501-1) lossisSSPC -} sp 10(Ze {- cov hlau dawb) kev nyiam huv.
Abrasive Xaiv:
Kev sivtsis - nws yog xim hlau abrasives(piv txwv li, garnet, alumina) kom tsis txhob muaj hlau sib kis.
Xyeej tsegTooj liab swblossistus hmab rau lwm tus hlau(Tej zaum yuav muaj cov khoom rov qab ua rau).
Profile Roughness: 50–75 μm(Thauj cov qauv rau xim nplaum).
2. Zeb nplai & xeb tshem tawm
Ua tiav Tshem Tawm: Qhov tseem ceeb txawm tias Q550NH's patina yog xav tau cov xim hauv qab.
Tshuaj Tu Mob:
Phosphoric acid (5-10% daws) kom hloov cov xeb uas muaj xeb ntawm cov hlau ntsev.
Yaug kom huv kom tsis txhob muaj xim tsis ua haujlwm.
3. Khaws cov huab cua cov khoom ntiag tug (yeem)
Rau hybrid system: Yog ib nrab patina yog khaws (piv txwv li, kev ua kom zoo nkauj):
Hnov sandblasting: Ntxuav tsuas thaj chaw uas tau pleev xim.
Xeb stabilizers: Thov tannic acid lossis cov tswv hloov hloov tshiab rau cov chaw tsis txhim kho ib cheeb tsam.
4. Priming & Xim Compatibility
Zinc -} primers nplua nuj: SivTsawg - zinclossisZinc SincericPrimers kom tsis txhob muaj kev cuam tshuam galvanic nrog CU / CR.
Epoxy / Polyurethane: Yuav tsum yogua tsis tauskom tso cai noo noo khiav tawm (zam kev tawg).
Kev kuaj: Tshawb cov adhesion los ntawmHla - Txiav Kuaj (ISO 2409)thiab ntsev txau tiv thaiv (ISO 9227).
5. Ib puag ncig tswj hwm
Kev vaum: Xim nyob rau hauv4-6 teevTom qab blasting (max 85% Rh).
Qho so: Thov ntawm10-35 degreeTxhawm rau kom kho tau.
