Saamaynta kala duwanaanshaha dhumucda dahaarka ee waxqabadka xaashida birta
Dhumucda dahaarka ayaa si weyn u saameeya caabbinta daxalka ee xaashida birta, cimilada, qaabaynta, iyo iska caabbinta saamaynta; si kastaba ha ahaatee, dhumucda xad-dhaafka ah waxay wax u dhimi kartaa dabacsanaanta iyo ku dhegganaanshaha. Caadi ahaan, wadarta dhumucda dahaarka ee xaashida birta midabaysan waxay ku dhacdaa inta u dhaxaysa 15-60 μm. Iyadoo dhumucda kordhinta ay guud ahaan kor u qaadayso waxqabadka ilaalinta, faa'iidooyinka yar ayaa u muuqda inay yareeyaan marka dhumucdiisu korodho.
Dahaarka dusha sare ee xaashida birta-sida Polyester (PE), Fluorocarbon (PVDF), ama Silicon-Modified Polyester (SMP) - uma adeegaan kaliya ujeeddo qurxin laakiin sidoo kale waxay u shaqeysaa sidii lakab difaac oo muhiim ah. Marka laga hadlayo dhumucda, "qafiifku had iyo jeer ma roona"; balse, waa in dheellitir wanaagsan lagu sameeyaa inta udhaxeysa adkeysiga, wax-ku-oolnimada, iyo iswaafajinta habraaca. Cilmi-baarista hadda jirta iyo hab-dhaqannada warshadaha ayaa muujinaya in kala duwanaanshaha dhumucda dahaadhka ay si nidaamsan u beddelaan waxqabadka xaashida birta ee gudaha adeegga iyada oo loo marayo habab ku lug leh saamaynta xannibaadda jirka, qaybinta walbahaarka, iyo xoogga isku xidhka wejiga.
Kala duwanaanta Dhumucda ugu Fiican: Codsiyada caadiga ah ee qalabka guriga iyo dhismaha guud, wadarta dhumucda dahaarka dabiiciga ah ee 20-25 μm (coat-ka sare) iyo 5-10 μm (primer) -oo wadartoodu tahay 25-35 μm - ayaa lagula talinayaa. Deegaannada cimilo-sare (sida dhirta korontada ama tas-hiilaadka kiimikada), nidaamka PVDF ku salaysan 40-60 μm ayaa ah doorashada la door bidayo.
Iska ilaali dhumuc la'aanta aan kala sooc lahayn: Dhumucda dahaarka ee ka badan 60 μm waxay u nugul yihiin arrimaha ay ka midka yihiin dhejinta oo yaraatay, dabacsanaan la'aanta, iyo dhibaatooyinka inta lagu jiro rakibidda; Intaa waxaa dheer, horumarinta waxqabadka korodhka ah ee la helay halbeeg dhumucdiisuna waxay si weyn hoos ugu dhacaysaa heerarkan.
Xulashada Walxaha waa in ay la jaanqaadaan Codsiga: Saqafyada dhismaha ee fudud, dhumucda dhexdhexaadka ah ee SMP ama HDP ayaa lagula talinayaa. Deegaannada ay ka jiraan xaaladaha daxalka daran, dahaarka PVDF oo ay weheliso dhumucdiisuna ku filan tahay waa in mudnaanta la siiyaa. Qaybaha saxda ah ee shaabadaysan, doorbidida waxaa lasiiyaa substrate-ka elektro-galvanized-kaasoo bixiya adkeysi sare-ku xiran dahaar dhuuban.
