Izingxenye ezimbili, i-epoxy primer enezinki ecebile yokuvikela isikhathi eside endaweni egqwala kakhulu
Isingeniso
Izingxenye ezimbili ze-anti-corrosion epoxy zinc primer yenziwe nge-epoxy resin, i-zinc powder, i-solvent, i-agent eyisizayo kanye ne-polyamide yokwelapha.
Izici
• Izakhiwo ezinhle kakhulu zokunqanda ukubola
• Ihlinzeka ngokuvikelwa kwe-cathodic ezindaweni ezilimele endaweni
• Izakhiwo ezinhle kakhulu zohlelo lokusebenza
• Ukunamathela okuhle kakhulu ekuqhumeni kwensimbi ye-carbon ehlanzekile
• Okuqukethwe uthuli lwezinc 20%,30%,40%,50%,60%,70%,80% kuyatholakala
Ukusetshenziswa okunconyiwe
Njengesiqalisi sezindawo zensimbi ezingenalutho ezihlanzwe ngokuqhunyiswa endaweni ephakathi kuya kweziqinile, njengezakhiwo zensimbi, amabhuloho, imishini yamachweba, izinkundla zasogwini, imishini yokwakha, amathangi okugcina namapayipi, izinsiza zikagesi, njll., kuhlanganiswe nokusebenza okuphezulu. amapende, angaqhubeka nokuthuthukisa ukusebenza kwe-anti-corrosion ye-coating;
Ingasetshenziswa ezindaweni ezigciniwe zesitolo esinezinki ezinothe;
Ingasetshenziselwa ukulungisa izindawo ezilimele zezingxenye zama-galvanized noma i-zinc silicate primer coating;
Ngesikhathi sokulungiswa, ingasebenzisa kuphela isivikelo sayo se-cathodic kanye nomphumela wokulwa nokugqwala endaweni ephathwa ngensimbi engenalutho.
Imiyalo yohlelo lokusebenza
Ukwelashwa Okusebenzayo kwe-Substrate kanye Nomphezulu:ukuqhuma kuhlanzwe ku-Sa2.5 (ISO8501-1) noma ubuncane be-SSPC SP-6, iphrofayela eqhumayo i-Rz40μm~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 libe yi-St3, kungagcinwa kuphela i-workshop enothe nge-zinc evunyiwe.
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 le-substrate ngesikhathi sokufakwa kanye nokwelashwa kufanele libe ngu-3℃ ngaphezu kwendawo yamazolo.
• Ukufaka isicelo ngaphandle akuvunyelwe esimweni sezulu esibi njengemvula, inkungu, iqhwa, umoya onamandla nothuli olunzima.
• Uma izinga lokushisa lendawo ye-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.
Phakathi nenqubo yokufaka isicelo, kufanele kuqashelwe ukunyakazisa njalo ukuvimbela impushana ye-zinc ukuthi ingahlali.
Amapharamitha wohlelo lokusebenza
| Indlela yohlelo lokusebenza | Iyunithi | Isifutho esingenamoya | Isifutho somoya | Ibhulashi/Irola |

| Ingaphezulu-yomile | 4 amahora | 2 amahora | 1 ihora | 30 imiz |
| Ngomile | Amahora angu-24 | 16 amahora | 12 amahora | 8 amahora |
| Isikhawu Sokumboza | Amahora angu-20 | 16 amahora | 12 amahora | 8 amahora |
| Isimo sokumboza | Ngaphambi kokufaka ijazi elilandelanayo, indawo engaphezulu kufanele ihlanzeke, yome futhi ingabi nosawoti we-zinc nokungcola. | |||
Amanothi:
--Ubuso kufanele bome futhi bungabi namagciwane
--Isikhawu sezinyanga ezimbalwa singavunyelwa ngaphansi kwesimo esihlanzekile sokuchayeka ngaphakathi
--Ngaphambi kokumboza noma yikuphi ukungcola okubonakalayo kufanele kususwe ngokuwasha isihlabathi, ukushanela ukuqhuma noma ukuhlanzwa ngomshini.
Ukwandulela & Okulandelayo
Ijazi elandulele:Isicelo esiqondiswe ngqo phezu kwensimbi noma idiphu eshisayo noma insimbi efafazwe ngokushisayo ngokwelashwa okungaphezulu kwe-ISO-Sa2½ noma i-St3.
Ijazi elilandelanayo:Ijazi eliphakathi le-mica elivundile, opende be-epoxy, Irabha ene-chlorinated... njll.
Akuhambisani nopende we-alkyd.
Ukupakisha & Isitoreji
Usayizi wephakethe:isisekelo 25kg, ukuphulukisa ejenti 2.5kg
Iphuzu elikhanyayo:>25℃(Ingxube)
Isitoreji:Kufanele igcinwe ngokuhambisana nemithetho kahulumeni wendawo.Indawo yokugcina impahla kufanele yomile, ipholile, ingene umoya futhi iqhelelane nokushisa nemithombo yomlilo.Ibhakede kufanele ligcinwe livalwe ngokuqinile.
Impilo yeshelufu:Unyaka ongu-1 ngaphansi kwezimo ezinhle zokugcina kusukela ngesikhathi sokukhiqiza.
