Izingxenye ezimbili eziqinile eziphakeme ngopende wokwakha, ukumelana kahle kakhulu namanzi olwandle, amakhemikhali, ukuguga nokuhlakazeka kwe-cathodic
Izici
Ukusebenza okuhle kokunamathela nokusebenza kwe-anti corrosion, ukumelana okuhle kakhulu kwe-cathodic disbandment.
Ukumelana okuhle kakhulu kwe-abrasion.
Ukumelana nokucwiliswa kwamanzi okuvelele;ukumelana okuhle kwamakhemikhali.
Izakhiwo ezinhle kakhulu zemishini.
Izembatho zasolwandle ezisindayo ezilwa nokugqwala, njengabo bonke abanye opende be-epoxy, mhlawumbe ushoki futhi baphele isikhathi eside ukuchayeka emkhathini we-ambient.Nokho, lesi simo asithinti ukusebenza kwe-anti-corrosion.
I-DFT 1000-1200um ingafinyelelwa ngesendlalelo esisodwa, ngeke ithinte ukusebenza kokunamathela nokusebenza okulwa nokugqwala.Lokhu kuzokwenza lula izinqubo zohlelo futhi kuthuthukise ukusebenza kahle.
Ngokusetshenziswa okujwayelekile, ukushuba kwefilimu okuphakanyisiwe kuphakathi kuka-500-1000 um.
Ukusetshenziswa okunconyiwe
Ukuvikela izakhiwo zensimbi ezindaweni ezigqwalile, njengezindawo ezingaphansi kwamanzi ezakhiwe ngasogwini lolwandle, izakhiwo zenqwaba, ukuvikelwa kodonga lwangaphandle lwamapayipi agqitshiwe, nokuvikelwa kwesakhiwo sensimbi ezindaweni ezifana namathangi okugcina, izitshalo zamakhemikhali, nezigayo zephepha.
Ukwengeza i-aggregate efanelekile engasheleli kungasetshenziswa njengesistimu yokumboza yedekhi engasheleli.
Ukugqoka okukodwa kungafinyelela kugqinsi lwefilimu elomile lama-microns angaphezu kuka-1000, okwenza kube lula kakhulu izinqubo zokufaka isicelo.
Imiyalo yohlelo lokusebenza
Ukwelashwa kwe-substrate kanye ne-surface
Insimbi:Zonke izindawo kufanele zihlanzeke, zome futhi zingabi namagciwane.Uwoyela namafutha kufanele kususwe ngokuhambisana nezinga le-SSPC-SP1 lokuhlanza i-solvent.
Ngaphambi kokufaka upende, zonke izindawo ezingaphezulu kufanele zihlolwe futhi ziphathwe ngokuhambisana nezinga le-ISO 8504:2000.
Ukwelashwa Okungaphezulu
Ukuqhunyiswa kwesihlabathi ukuze kuhlanzwe indawo kuzinga le-Sa2.5 (ISO 8501-1:2007) noma i-SSPC-SP10, ukuhwaqeka kobuso okungu-40-70 microns (2-3 mils) kuyanconywa.Ukulimala okungaphezulu okuvezwe ngokuqhunyiswa kwesihlabathi kufanele kugaywe, kugcwaliswe noma kuphathwe ngendlela efanele.
Indawo evunyiwe ye-primer kumele ihlanzeke, yome, futhi ingabi nosawoti oncibilikayo kanye nanoma yiziphi ezinye izinto ezingcolisayo.Iziqalo ezingagunyaziwe kufanele zihlanzwe ngokuphelele ziye ezingeni le-Sa2.5 (ISO 8501-1:2007) ngokuqhunyiswa kwesihlabathi.
Thinta phezulu:Ifanele ukumbozwa kwesendlalelo sokuguga esiqinile nesiphelele.Kodwa ukuhlolwa kwendawo encane kanye nokuhlolwa kuyadingeka ngaphambi kokufaka isicelo.
Enye indawo:sicela uthintane ne-ZINDN.
Kuyasebenza Futhi Ukwelapha
● Izinga lokushisa lendawo ezungezile kufanele libe ukusuka ku-5℃ ukuya ku-38℃, umswakama womoya ohlobene akufanele ube ngaphezu kwama-85%.
● Izinga lokushisa elingaphansi komhlaba ngesikhathi sokufakwa kanye nokwelapha kufanele libe ngu-3℃ ngaphezu kwendawo yamazolo.
● Ukusetshenziswa kwangaphandle akuvunyelwe esimweni sezulu esibi njengemvula, inkungu, iqhwa, umoya onamandla nothuli olunzima.Ngesikhathi sokuphulukisa uma ifilimu yokumboza ingaphansi komswakama ophezulu, usawoti we-amine ungenzeka.
● Ukuminyanisa phakathi noma ngokushesha ngemva kokufakwa kuzophumela endaweni ebuthuntu kanye nesendlalelo sokunamatha esisezingeni eliphansi.
● Ukuchayeka ngaphambi kwesikhathi emanzini amile kungabangela ukushintsha kombala.
