Laba qaybood oo ka kooban, firfircooni leh zinc-hodon primer ee ilaalinta muddada dheer ee birta ee bay'adaha daxalka daran
Hordhac
Epoxy zinc primer oo ka kooban laba qaybood oo ka-hortagga daxalka wuxuu ka kooban yahay xabagta epoxy, budada zinc, dareere, wakiil caawiye iyo wakiilka daaweynta polyamide.
Astaamaha
• Sifooyin ka hortag ah oo heer sare ah
Waxay siisaa ilaalinta cathodic meelaha dhaawaca ah
• Guryaha codsiga oo aad u wanaagsan
Xabag heer sare ah oo lagu qarxiyo sagxadaha birta kaarboon ee la nadiifiyay
• Boodhka Zinc 20%,30%,40%,50%,60%,70%,80% ayaa diyaar ah
Isticmaalka lagu taliyay
Sida aasaasiga ah ee meelaha birta qaawan ee dhexdhexaadka ah ama meelaha daxalka daran, sida dhismooyinka birta, buundooyinka, mishiinada dekedaha, meelaha xeebaha ah, mishiinada dhismaha, taangiyada kaydinta iyo dhuumaha, tas-hiilaadka tamarta, iwm, oo ay weheliso waxqabadka sare rinji, kaas oo sii wanaajin kara waxqabadka ka hortagga dahaadhka;
Waxa loo isticmaali karaa meelaha hore ee dukaanka hodanka ku ah zinc ee la ansixiyay;
Waxaa loo isticmaali karaa hagaajinta meelaha dhaawacan ee qaybaha galvanized ama daahan zinc silicate primer;
Inta lagu jiro dayactirka, waxay sameyn kartaa oo kaliya ilaalinta cathodic-ka iyo saameynta ka-hortagga miridhku ee dusha lagu daweeyo birta qaawan.
Tilmaamaha Codsiga
Daawaynta Substrate-ka ah ee lagu dabaqi karo:qaraxa waxaa lagu nadiifiyey Sa2.5 (ISO8501-1) ama ugu yaraan SSPC SP-6, profile qarxinta Rz40μm~75μm (ISO8503-1) ama qalab koronto la nadiifiyey ugu yaraan ISO-St3.0/SSPC SP3
Aasaaska aqoon-is-weydaarsiga hore loo dahaadhay:Alxanka, hagaajinta rashka iyo burburka waa in lagu nadiifiyaa Sa2.5 (ISO8501-1), ama qalab koronto lagu nadiifiyo St3, kaliya aasaasaha aqoon-is-weydaarsiga zinc-ga hodanka ah ee la ansixiyay waa la hayn karaa.
Lagu dabaqi karo oo lagu daaweynayo
Heerkulka deegaanku waa inuu ahaadaa laga jaray 5℃ ilaa 38℃, qoyaanka hawadu waa in aanu ka badnayn 85%.
• Heerkulka substrate inta lagu jiro codsiga iyo daaweynta waa in uu ahaado 3 ℃ oo ka sarreeya barta sayaxa.
• Codsiga dibadda waa mamnuuc cimilo daran sida roobka, ceeryaamo, baraf, dabayl xooggan iyo boodh culus.
• Marka heerkulka deegaanka uu yahay -5 ~ 5 ℃, alaabada heerkulka hoose waa in la isticmaalaa ama tallaabooyin kale waa in la qaadaa si loo hubiyo daaweynta caadiga ah ee filimka rinjiga.

Hababka codsiga
Buufin-la'aan hawo buufin ah
Dahaarka burushka iyo rullaluistuadka waxa kaliya oo lagula talinayaa jaakad xariijimo ah, daahan yar oo meel yar ah ama hagaajinta.
Inta lagu guda jiro habka codsiga, fiiro gaar ah waa in la bixiyaa walaaqin joogta ah si looga hortago in budada zinc ay degto.
Hababka Codsiga
| Habka codsiga | Unug | Buufin aan hawo lahayn | buufinta hawada | burush/Roller |
| Afka birta | mm | 0.43 ilaa 0.53 | 1.8 ilaa 2.2 | —— |
| Cadaadiska sanka | kg/cm2 | 150 ilaa 200 | 3～4 | —— |
| Ka khafiifsan | % | 0～10 | 10 ilaa 20 | 5～10 |
Qalajinta & Daawaynta
| Heerkulka dusha sare ee substrate | 5℃ | 15℃ | 25℃ | 35℃ |
| Dusha-qallalan | 4 saac | 2 saac | 1 saac | 30 daqiiqo |
| Iyada oo qallalan | 24 saac | 16 saac | 12 saac | 8 saacadood |
| Dhexda Dahaarka | 20 saac | 16 saac | 12 saac | 8 saacadood |
| Xaaladda dahaarka | Kahor intaadan isticmaalin jaakadda ka dhalan karta, dusha sare waa inuu ahaado nadiif, engegan oo aan lahayn milixda zinc iyo wasakhowga. | |||
Xusuusin:
-- Dusha sare waa inay ahaataa mid engegan oo aan wasakhayn lahayn
--Mudo dhowr bilood ah ayaa la ogolaan karaa iyadoo xaalad nadiif ah oo gudaha ah lagu jiro
Kahor inta aan la daahin wixii wasakhaysan dusha sare ee muuqda waa in lagu saaraa ciid dhaqid, qashin xaaq ama nadiifin farsamo
Hordhac & Daahfurka ka dambeeya
Jaakada hore:Codsiga tooska ah ee dusha sare ee birta ama galvanized kulul ama birta kulul lagu buufiyo oo leh daawaynta dusha sare ee ISO-Sa2½ ama St3.
Jaakad ka dhalatay:Ferric mica dhexda jaakad, rinji epoxy, caag koloriin leh...iwm.
Aan ku habboonayn rinjiga alkyd.
Baakaynta & Kaydinta
Cabbirka xirmada:saldhiga 25kg, daawaynta wakiilka 2.5kg
Barta Tooshka ah:> 25 ℃ (isku darka)
Kaydinta:Waa in lagu kaydiyaa si waafaqsan xeerarka dawladda hoose.Deegaanka wax lagu kaydiyo waa inuu ahaadaa mid qalalan, qabow, hawo wanaagsan leh oo ka fog kulaylka iyo ilaha dabka.Xirmada waa in si adag loo xiraa.
Nolosha shelf1 sano oo ku hoos jira xaalado kaydin wanaagsan laga bilaabo wakhtiga wax soo saarka.
