Siv
- Haum rau steel qauv, roj tank, roj tank, tshuaj anticorrosion khoom, electromechanical khoom, thauj tsheb raws li antirust priming txheej.
Kev kho saum npoo
- Steel nto sandblasting rau qib Sa2.5, nto roughness 30um-75um.
- Cov cuab yeej hluav taws xob descaling rau qib St3.
pob khoom ua ntej
- Directly pleev xim rau ntawm cov hlau nto uas nws xeb tshem tawm zoo mus txog qib Sa2.5.
Tom qab sib phim
- Polyurethane mica xim, polyurethane xim, acrylic polyurethane sab saum toj lub tsho, fluorocarbon saum lub tsho.
Kev tsim kho tsis raug
- Pom zoo zaj duab xis thickness: 60-80um
- Theoretical npaum li cas: txog 115g / m² (raws li 35um qhuav zaj duab xis, tsis suav nrog poob).
- Pom zoo tus naj npawb ntawm painting passes: 2 ~ 3 passes
- Cia kub: -10 ~ 40 ℃
- Kev tsim kho kub: 5 ~ 40 ℃
- Lub sijhawm sim: 6h
- Kev tsim kho txoj kev: txhuam, cua txau, dov tuaj yeem ua tau.
- Painting ncua sijhawm:
Substrate kub ℃ 5-10 15-20 25-30
Shorter luv h48 24 12
Lub sijhawm ncua ntev tsis tshaj 7 hnub. - Lub substrate kub yuav tsum siab tshaj qhov dew point ntawm ntau tshaj 3 ℃, thaum lub substrate kub yog qis dua 5 ℃, cov xim zaj duab xis yog tsis kho, yuav tsum tsis txhob tsim.
Painting kev tsim kho
- Tom qab qhib lub thoob ntawm cov khoom A, nws yuav tsum tau nplawm kom zoo, tom qab ntawd ncuav cov khoom xyaw B rau hauv cov khoom A hauv qab nplawm raws li qhov yuav tsum tau ua, sib tov zoo, cia nws sawv ntsug thiab ua noj rau 30 feeb, tom qab ntawd ntxiv qhov tsim nyog ntawm thinner thiab kho. nws mus rau kev tsim kho viscosity.
- Diluent: tshwj xeeb diluent rau polyurethane series.
- Airless txau: Dilution npaum li cas yog 0-5% (los ntawm qhov hnyav piv ntawm cov xim), nozzle caliber yog 0.4mm-0.5mm, txau siab yog 20MPa-25MPa (200kg / cm²-250kg / cm²).
- Cua txau: Dilution npaum li cas yog 10-15% (los ntawm qhov hnyav piv ntawm cov xim), nozzle caliber yog 1.5mm-2.0mm, txau siab yog 0.3MPa-0.4MPa (3kg / cm²-4kg / cm²).
- Cov menyuam txheej: Dilution tus nqi yog 5-10% (raws li cov xim hnyav piv).
Cov kev ceev faj
- Nyob rau hauv lub caij ntuj sov kev tsim kho, yooj yim rau qhuav tshuaj tsuag, thiaj li tsis txhob qhuav tshuaj tsuag tuaj yeem kho nrog thinner kom txog thaum tsis qhuav tshuaj tsuag.
- Cov khoom no yuav tsum tau siv los ntawm cov kws tshaj lij tha xim ua haujlwm raws li cov lus qhia ntawm pob khoom lossis phau ntawv no.
