Ntawm no yog ib qho kev qhia dav rauPainting ASTM \/ BS4360 Miner Lub Tsev Cov Qauv Qis Quav Qoob Las Thiab High-Lub Zog Hlau, npog cov khoom npaj ntev, xim pleev xim, kev thov cov ntaub ntawv, thiab kev coj ua zoo:

1. Kev npaj saum npoo

Kev npaj kom zoo yog qhov tseem ceeb rau cov xim nplaum thiab kev tiv thaiv corrosion. Ua raws li cov kauj ruam no:

a. Ntxuav

Ncab: Siv cov kuab tshuaj (piv txwv li, acetone, ntxhia pob zeb) kom tshem tawm cov roj, roj, thiab paug.

Xeb thiab Teev Tshem Tawm:

Txhaj koob tshuaj tiv thaiv blasting: Ua tiavSa2.5(nyob ze-cov hlau dawb) lossisSA3(Dawb hlau) ib iso 8501-1 rau cov chaw siab corrosion.

Tes \/ Cov Cuab Yeej Hluav Taws Xob: Siv hlau txhuam lossis cov grinders rau lub teeb muaj xeb (ST2 \/ ST3), tab sis qhov no tsis muaj txiaj ntsig tsawg dua li blasting.

Plua Plav Tawm: So nrog daim ntaub tack lossis siv cov cua compressed kom tshem cov khib nyiab.

b. Nto profile

Txhaj tshuaj blasting tsim a40-75 micron thauj tog rau nkoj txawv txawvtxhawm rau txhim kho cov xim pleev xim. Rau high-zog steels, xyuas kom meej tias tsis muaj abrasive nyob (piv txwv li, cov hlau hais) uas tuaj yeem ua rau Galvanic corrosion.

2. Xim tshuab rau cov phiaj hlau

Xaiv cov xim pleev xim raws li kev sib kis thiab kev ua kom ruaj khov:

a. Peb-lub tsho tiv no (qauv rau cov chaw hnyav)

Tawv tsiaj	Lub hom phiaj	Cov Khoom Siv Hom	Qhuav Zaj Duab Xis Thickness (DFT)
Lub zim teb	Corrosion tiv thaiv	- Zinc-nplua nuj Epoxy (80-90% zinc stuffs). - Inorganic zinc silicate (rau qhov kub siab tiv thaiv).	75-100 microns
Nruab nrab	Tsim cov yeeb yaj kiab tuab, txhim kho corrosion tsis kam	- Epoxy mastast. - Polyurethane Intermediate.	100-150 microns
To topcoat	UV Kuj, Kev Lom Zem	- Polyurethane (glossy, xim ruaj khov). - Acrylic lossis alkyd (rau ib puag ncig me ntsis).	50-80 microns

b. Ob-lub tsho tiv no (lub teeb kom pom ib puag ncig)

Primer + Topcoat:

Primer: Zinc-nplua nuj Epoxy lossis zinc phosphate.

Topcoat: Polyurethane lossis Acrylic Enamel.

Tag nrho DFT: 150-200 microns.

c. Ib Leeg Tsho Hluav Taws Xob (ib ntus lossis cov cheeb tsam tsawg)

Siv cov xim av tsis muaj av (DFT: 80-100 microns) rau kev tiv thaiv sab hauv lossis kev tiv thaiv luv luv.
