Ukukhetha ipeyinti yemizi-mveliso efanelekileyo kufuna ukuqwalaselwa kwezinto ezininzi, kuquka indawo yokusetyenziswa, uhlobo lwesiseko, iimfuno zokusebenza, njl.
2.1 Khetha ngokwemeko yokusetyenziswa
Imeko yangaphakathi: Ukusetyenziswa ngaphakathi, kuyacetyiswa ukuba ukhethe ipeyinti esekwe emanzini okanye ipeyinti esekwe kwi-SOC ephantsi ukuze kuncitshiswe ungcoliseko lomoya.
Indawo engaphandle: Iipeyinti ezisetyenziswa ngaphandle kufuneka zibe nokumelana okuhle kwemozulu kunye nokumelana ne-UV. Iipeyinti zomgubo we-polyester okanye iipeyinti ezisekelwe kwisinyibilikisi ezimelana kakhulu nemozulu ziyacetyiswa.
2.2 Ukukhetha ngokusekelwe kuhlobo lwesiseko
I-Metal Substrate: Kwiindawo zesinyithi, ipeyinti ye-epoxy kunye nepeyinti ye-polyurethane zikhetho ezilungileyo, zinamathela kakuhle kwaye zinokumelana nokugqwala.
I-substrate yekhonkrithi: Ipeyinti ye-epoxy esekwe emanzini kunye neengubo ezikhethekileyo ezingangeni manzi zifanelekile kwiindawo zekhonkrithi kwaye zinokuthintela ngokufanelekileyo ukuvuza kwamanzi kunye nokugqwala.
2.3 Ukukhetha ngokusekelwe kwiimfuno zokusebenza
Ukumelana neekhemikhali: Ukuba ipeyinti ifuna ukumelana nokuhlaselwa ziikhemikhali, ipeyinti ye-epoxy yeyona ndlela ilungileyo.
Ukumelana nokurhawuzelelwa: Kwimigangatho nakwizixhobo zoomatshini, ipeyinti ye-polyurethane kunye nomgubo wokugquma zinokumelana nokurhawuzelelwa okuhle.
3. Iindawo zokusetyenziswa kweepeyinti zoshishino kunye neengubo
3.1 Ukwenziwa kweMishini
Kwishishini lokuvelisa oomatshini, iipeyinti zisetyenziswa kakhulu ukuthintela umhlwa nokuphucula ukubonakala kwezixhobo. Iipeyinti ze-epoxy kunye ne-polyurethane zihlala zisetyenziswa, nto leyo eyandisa ubomi bezixhobo ngempumelelo.
3.2 Ishishini Lokwakha
Imfuno yeshishini lokwakha yeengubo igxile kakhulu ekuthinteleni amanzi, ukhuseleko lomlilo, kunye nokuhombisa. Iingubo ezithintela umlilo kunye neengubo ezisekelwe emanzini zisetyenziswa kakhulu ekwakheni ukuhlangabezana neemfuno ezahlukeneyo zokusebenza.
