I-polyamide adduct enezingxenye ezimbili ephakathi kapende we-polyamide welashiwe, isithiyo esihle kanye nezakhiwo ze-anticorrosion, imelana kahle namanzi, uwoyela, amakhemikhali, indawo yokuhlanganisa ende
Izici
Ngenxa yenani elikhulu le-mica iron oxide ehlanganisiwe ehlanganisiwe, yakha umphumela "we-labyrinth" kufilimu kapende, ngakho-ke ifilimu yopende inomgoqo omuhle kakhulu nokumelana nokugqwala.
Ukumelana okuhle kakhulu nomkhathi wamakhemikhali, umkhathi wezimboni kanye nomkhathi wasolwandle, futhi unokumelana okuhle namanzi olwandle, usawoti, i-asidi ebuthakathaka kanye ne-alkali ebuthakathaka.Izikhawu ezinde zokubuyisela kabusha.
Ukusetshenziswa okunconyiwe
I-1.Isetshenziswa njengesendlalelo esimaphakathi kanye nokuvala uphawu kwamapende aphikisana nokugqwala afana ne-epoxy zinc-rich rich primer kanye ne-inorganic zinc-rich primer ukuze kuthuthukiswe umgoqo kanye nezakhiwo zokuvikela zayo yonke i-coating.
I-2.Isetshenziswa njenge-antirust primer yezakhiwo zensimbi.
3.Isetshenziswa njenge-interlayer ohlelweni lokumboza ukuze kuvikelwe ukhonkolo.
I-4.Isetshenziswa njenge-topcoat yokulungisa phezu kwezingubo ezindala lapho ukuhambisana kuvumela khona.
Imiyalo yohlelo lokusebenza
Insimbi:ukuqhuma kuhlanzwe ku-Sa2.5 (ISO8501-1) noma ubuncane be-SSPC SP-6, iphrofayela eqhumayo i-Rz30μm~75μm (ISO8503-1) noma ithuluzi lamandla elihlanzwe ukuze libe ubuncane be-ISO-St3.0/SSPC SP3
I-primer ye-workshop ehlanganiswe ngaphambili:Ukushisela, ukulinganisa iziqhumane kanye nomonakalo kufanele ukuqhuma kuhlanzwe ku-Sa2.5 (ISO8501-1), noma ithuluzi lamandla lihlanzwe ku-St3.0.
Ingaphezulu eline-primer eboshwe:Hlanza futhi wome ngaphandle kukasawoti we-zinc nokungcola.
Thinta phezulu:Susa amafutha phezulu bese ususa usawoti nokunye ukungcola.Kungcono ukusebenzisa ukuhlanza ukuqhuma ukususa ukugqwala nezinye izinto ezixekethile.Sebenzisa ithuluzi lamandla ukupholisha indawo yokugqwala, futhi uphinde uvale le nto.
Kuyasebenza Futhi Ukwelapha
1.Izinga lokushisa lendawo ezungezile kufanele libe ukusuka ku-5℃ ukuya ku-35℃, umswakama womoya ohlobene akufanele ube ngaphezu kuka-80%.
2.Izinga lokushisa le-substrate ngesikhathi sokufakwa kanye nokwelapha kufanele libe ngu-3℃ ngaphezu kwendawo yamazolo.
3.Ukufaka isicelo sangaphandle akuvunyelwe esimweni sezulu esibi njengemvula, inkungu, iqhwa, umoya onamandla nothuli olunzima.
Izinhlelo zokusebenza
● 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.
● Uma izinga lokushisa le-Ambient liku-5~5℃, kufanele kusetshenziswe imikhiqizo yokwelapha epholile ephansi noma kufanele kuthathwe ezinye izinyathelo ukuze kuqinisekiswe ukuphulukiswa okuvamile kwefilimu kapende.

Izindlela zokufaka isicelo
Isifutho esingenamoya/Isifutho somoya
Ukugqoka ibhulashi ne-roller kunconywa kuphela ngejazi lemigqa, ukumbozwa kwendawo encane noma ukulungisa.

Ukwandulela & Okulandelayo
Ijazi elandulele:I-Epoxy zinc phosphate, i-Epoxy zinc ecebile, i-Epoxy primer, ingasetshenziswa futhi ngokuqondile ekuqhumeni kwensimbi okuhlanzwe ku-Sa2.5 (ISO8501-1).
Ijazi elilandelanayo:I-Epoxy topcoat, i-Polyurethane, i-Fluorocarbon, i-Polysiloxane...njll
Ukupakisha & Isitoreji
Ukupakisha:isisekelo 25kg, i-ejenti yokwelapha 3kg
Iphuzu elikhanyayo:>25℃(Ingxube)
Isitoreji:Kufanele igcinwe ngokuhambisana nemithetho kahulumeni wendawo.Indawo yokugcina impahla kufanele yomile, ipholile, ingene umoya futhi iqhelelane nokushisa nemithombo yomlilo.Isitsha sokupakisha kufanele sigcinwe sivalwe ngokuqinile.
Impilo yeshelufu:Unyaka ongu-1 ngaphansi kwezimo ezinhle zokugcina kusukela ngesikhathi sokukhiqiza.
