Rinji noocee ah ayaan isticmaaleynin tuubooyinka birta galvanized-ka ah?

Dusha sare ee birta birta ah ee galvanized waa mid aad u siman, isticmaalka dheer ee substrate-ka ayaa sidoo kale dhici doona miridhku, si loo hubiyo isticmaalka caadiga ah ee tuubada galvanized, habka rinjiyeynta ayaa si fiican u ilaalin kara birta.Si kastaba ha noqotee, tuubooyinka birta ah ee galvanized, inta badan rinjiga loogu talagalay dhejinta dusha sare ee galvanized ma fiicna, filimka rinjiga iyo dhejinta dusha siman ayaa liidata, u nugul in ay daboolaan dhibaatada, sidaas darteed tuubada birta galvanized leh rinjigee ka fiican?

ED1000 Epoxy Primer waa dahaar gaar ah oo loogu talagalay dusha sare ee substrate galvanized oo leh dhejis heer sare ah iyo ilaalin wanaagsan oo loogu talagalay tuubooyinka galvanized.Tilmaamaha ugu muhiimsan ee asaasiga ah waa:

1. Ku habboon substrate galvanized, birta aan lahayn, aluminium aluminium, saxan aluminium ah iyo biraha kale ee siman, adhesion xooggan, adhesion film;

2, daawaynta dusha sare ee substrate waa mid fudud, ma jirto ciid, wax shiiditaan, isticmaalka dareeraha si looga saaro saliidda waa la dhisi karaa, badbaadinta xoogga iyo kharashka alaabta;

3, iska caabin ah buufin milix filim waa mid xoogan, ilaa 1000 saacadood, daahan waa dhawrsan, oo leh anticorrosive aad u fiican iyo iska caabin miridhku;

4. Rinjiga kuma jiraan biraha culus, sunta rasaasta iyo chromium, oo waafaqsan heerarka qiiqa dareeraha ee EU, wuxuuna ku habboon yahay dhoofinta daahan workpiece;

5, waxaa lagu dhejin karaa rinji dhameystiran oo kala duwan, sida rinjiga fluorocarbon, rinjiga polyurethane, rinjiga epoxy, rinji akril, iwm.

Dhuumaha birta galvanized waa in la saaraa ka hor rinjiyeynta saliidda dusha, isticmaalka dareeraha si loo tirtiro dusha sare ee substrate ayaa si wax ku ool ah u saari kara saliidda saliidda, si looga fogaado saameyn ku yeelashada adhesion.Codso ED1000 epoxy primer by buufin, isku darka asaasiga ah iyo wakiilka daweynta ee saamiga 9:1, ku dar dhuuban epoxy, walaaq si siman, oo jaakad ilaa dhumucda filimka la cayimay.Dhumucda filimka lagu taliyey waa 70μm.

ED1000 epoxy primer waxay leedahay xabag xoog leh iyo iska caabin daxalka aad u fiican, laakiin iska caabinta cimilada liidata, gaar ahaan isticmaalka dibadda, waxay u baahan tahay in lagu dhejiyo jaakad sare oo cimilada u adkaysata.Koodhka sare ee sida caadiga ah loo isticmaalo, sida rinjiga fluorocarbons, acrylic polyurethane topcoat iyo acrylic topcoat.Ka dib marka la qalajiyo furaha, mari jaakad sare oo ku buufi dhumucda filimka la cayimay.Dhumucda filimka lagu taliyey waa 50-60μm.

Dhuumaha galvanized oo leh dahaarka asaasiga ah iyo dhamaystirka, filimka daahan wuxuu leeyahay adhesion aad u fiican, iska caabin daxalka, qurxinta iyo iska caabinta cimilada, inta badan deegaanka waxay noqon kartaa ilaalin aad u wanaagsan.
