I-primer esekelwe emanzini ecebile nge-zinc yesakhiwo sensimbi
Ukusebenza komkhiqizo
Ikhono elihle le-anti-corrosion ukuze lihlangabezane nezidingo zokuvikela zayo yonke i-coating;
Ukusebenzisa amanzi njengendlela yokusabalalisa, azikho izinto ezinobuthi neziyingozi ezikhiqizwa ngesikhathi sokwakhiwa kanye nenqubo yokwenza ifilimu yokumboza, ehlangabezana nezidingo zokuvikelwa kwemvelo;ukuphulukiswa kwezingxenye ezimbili, ubulukhuni obuhle, ukunamathela okuhle, nokumelana namakhemikhali;
Ukuhambisana kuhle, ifilimu yokugqoka inamathele ngokuqinile ku-substrate yensimbi, futhi ukunamathela kwefilimu yokugqoka ephezulu kungathuthukiswa.
Ibanga lohlelo lokusebenza
Ilungele ukulwa nokugqwala kanye ne-anti-corrosion yezindawo zensimbi ezinzima zezakhiwo ezihlukahlukene zensimbi ezinkulu, imikhumbi, imishini yemishini, amabhuloho, njll.
Ukwelashwa kwendawo
Susa amafutha, amafutha, njll nge-ejenti yokuhlanza efanelekile.I-Sandblasted kuya ku-Sa2.5 grade noma i-SSPC-SP10 grade, i-surface roughness ilingana ne-Rugotest standard N0.3.Ukwakhiwa kungakapheli amahora angu-6 ngemva kwe-sandblasting kuyisixazululo esingcono kakhulu.
Incazelo Yokwakha
Ingasetshenziswa nge-roller, ibhulashi kanye nesifutho.I-high pressure airless spray iyanconywa ukuze uthole ifilimu efanayo nenhle yokuhlanganisa.
Ngaphambi kokwakhiwa, uketshezi lwengxenye ye-AB kufanele luxutshwe ngokulinganayo nge-mixer kagesi, bese ingxenye ye-AB ixutshwe ngokulinganayo.Ngaphambi kokwakhiwa, kunconywa ukuvala i-inlet feed ngesihlungi se-80-mesh.Uma i-viscosity ikhulu kakhulu, ingahlanjululwa ngamanzi ku-viscosity yokwakha.Ukuze kuqinisekiswe ikhwalithi yefilimu kapende, sincoma ukuthi inani le-dilution libe ngu-0% -10% wesisindo sokuqala sikapende.Umswakama ohlobene ungaphansi kwama-85%, futhi izinga lokushisa endaweni yokwakha likhulu kuno-5°C futhi likhulu kunezinga lokushisa lamazolo ngo-3°C.Imvula, iqhwa nesimo sezulu akukwazi ukusetshenziswa ngaphandle.Uma ukwakhiwa sekuvele kwenziwa, ifilimu yepende ingavikelwa ngokuyimboza ngeseyili.
Amaphakheji anconyiwe
I-Primer FL-128D/133D esekelwe emanzini epoxy zinc ecebile izikhathi ezingu-1-2
Upende ophakathi nendawo FL-123Z upende omaphakathi we-epoxy micaceous iron osuselwe emanzini isikhathi esingu-1
I-Topcoat FL-139M/168M i-polyurethane/i-fluorocarbon topcoat esekwe emanzini izikhathi ezi-2, ukujiya okuhambisanayo kungabi ngaphansi kuka-250μm
