Cov lus qhia siv
Siv tau substrate thiab nto kho
1, Steel substrate kev kho mob: sandblasting los yog tua blasting kom tshem tawm xeb mus rau Sa2.5 qib, roughness 40 ~ 70um, txhim khu lub adhesion ntawm txheej thiab substrate.
2, Thaum siv, do tivthaiv A ua ntej, tom qab ntawd ntxiv cov tshuaj tua kab B proportionally, do tusyees, tuav lub sijhawm induction 15 ~ 30 feeb, kho daim ntawv thov viscosity nrog ib qhotsim nyog tus nqi ntawmtshwj xeeb thinner raws li txoj kev thov.
Txoj kev thov
1, Airless tsuag, cua txau lossis cov menyuam
Txhuam thiab cov menyuam txheej tsuas yog pom zoo rau lub tsho stripe, me me txheej txheej lossis kov.
2, Pom zoo kom qhuav zaj duab xis thickness: 300um, ib txheej txheej yog li 100um.
3, Muab qhov chaw corrosive kuj hnyav, thiab cov txheej uas ploj lawm yuav ua rau cov hlau corrode sai, txo cov kev pab cuam lub neej.
vim yog kev siv ib puag ncig corrosive ntawm txheej zaj duab xis yog qhov muaj zog heev, cov dej xau yuav ua rau cov txheej txheem corrode sai thiab txo cov kev pab cuam lub neej.
Desulfurization & denitrification ntaus ntawv sab hauv phab ntsa daim ntawv thov cov lus qhia
Kev kho saum npoo
Roj los yog roj yuav tsum raug tshem tawm raws li SSPC-SP-1 hnyav tu tus qauv.
Nws raug nquahu kom tshuaj tsuag cov hlau nto rau Sa21/2 (ISO8501-1: 2007) lossis SSPC-SP10 tus qauv.
Yog tias oxidation tshwm sim ntawm qhov chaw tom qab txau thiab ua ntej pleev xim rau cov khoom no, ces qhov saum npoo yuav tsum rov jetted.Ua tau raws li cov qauv kev pom pom.Cov teeb meem saum npoo uas tshwm sim thaum lub sij hawm tshuaj tsuag yuav tsum tau sanded, sau, los yog kho kom tsim nyog.Qhov pom zoo roughness yog 40 mus rau 70μm.Substrates kho los ntawm sandblasting los yog tua blasting yuav tsum tau primed nyob rau hauv 4 teev.
Yog tias lub substrate tsis kho raws li qhov xav tau, nws yuav ua rau xeb rov qab, xim zaj duab xis flaking, xim zaj duab xis tsis xws luag thaum tsim kho, thiab lwm yam.
Kev qhia ntawv thov
Kev sib xyaw: Cov khoom yog ntim nrog ob lub ntsiab lus, Pawg A thiab Pab Pawg B. Qhov sib piv yog raws li cov khoom lag luam tshwj xeeb lossis daim ntawv lo ntawm lub thawv ntim.Sib tov A tivthaiv zoo nrog lub tshuab fais fab ua ntej, tom qab ntawd ntxiv B tivthaiv proportionally thiab do zoo.Ntxiv qhov tsim nyog tus nqi ntawm epoxy thinner, dilution ratio ntawm 5 ~ 20%.
Tom qab cov xim sib tov thiab nplawm zoo, cia nws loj tuaj rau 10 ~ 20 feeb ua ntej thov.Lub sij hawm maturing thiab lub sij hawm siv yuav luv luv vim qhov kub nce.Cov xim uas tau teeb tsa yuav tsum tau siv rau hauv lub sijhawm siv tau.Cov xim uas dhau lub sijhawm siv yuav tsum muab pov tseg los ntawm cov khib nyiab thiab yuav tsum tsis txhob siv dua.
