Gariiradaha Birta ee PPGI oo leh Midabo kala duwan iyo Lakabka Zinc
Sharaxaada badeecada
Gariiradda birta Galvanized ee Prepained oo leh Dhammaan Koodhka Midabka RAL waa 'bir kaas oo walxaha dahaadhka ah (tusaale rinji, filim...) lagu dahaadhay gariiradda'. Marka lagu dhejiyo substrate-ka macdan, walxaha dahaarka ah (oo dareere ah, koollo ah ama qaab budo ah) waxay sameeyaan filim leh difaac, qurxiyo iyo/ama sifooyin kale oo gaar ah.
Muddo 40 sano ah, wax-soo-saarka birta ee Yurub ee prepainted ayaa ku dhufatay 18.
Birta
Doorashada substrate-macdan waxaa lagu go'aamiyaa cabbirka, farsamada iyo guryaha iska caabinta daxalka ee looga baahan yahay alaabta dahaarka leh ee la isticmaalayo. Substrate-yada ugu caansan ee birta ah ee dabiiciga ah lagu dahaadhay waa:
Heerkulul kulul oo galvanized steel (HDG) oo ka kooban substrate bir qabow oo la dhimay kaas oo lakabka zinc lagu dahaadhay hab kuleyl kulul si loo siiyo guryaha daxalka la xoojiyey ee birta salka.
birta khafiifka ah ee galvanized (GMS) waxa loo isticmaali karaa sidii balastar iyo bir gacan ee jaranjarada, tuubooyinka iyo iwm.
Aloysyada kale ee zinc-ku-salaysan ayaa lagu dahaadhay birta waxaana loo isticmaalaa sida substrate ee daahan gariiradda, taasoo siinaya siyaalo kala duwan. Waxay bixiyaan caabbinta daxalka oo soo hagaagtay xaalado gaar ah.
★ birta dahaarka leh ee Electro-galvanized (EG) waxay ka kooban tahay substrate qabow oo la dhimay kaas oo lakabka zinc lagu dahaadhay habka korantada.
★ birta la dhimay qabow (CR) iyada oo aan lahayn daahan zinc ah
★ aluminium alwaax ah oo la sameeyay
Substrates kale oo badan ayaa si dabiici ah loo dahaadhay: zinc/iron, birta aan la taaban karin, tinplate, bross, zinc iyo copper.
Dahaarka
Noocyo badan oo dahaar dabiici ah ayaa loo isticmaalaa birta la sii hagaajiyay, loo sameeyay si loo bixiyo heerar kala duwan oo adkeysi iyo waxqabad, ama lagu qanciyo shuruudaha qurxinta kala duwan. Dahaarka ugu badan ee la marsado waxay ku salaysan yihiin rinji dareere ah, inkastoo filimada (sidoo kale loo yaqaan laminates) iyo daahan budada ah ayaa loo isticmaalaa tiro yar. Kuwaani waa rinji dareere ah (tusaale, alwaaxyada, koodhadhka dhabarka lagu xidho, polyester-ka, plastisols, polyurethane, polyvinylidene fluorides (PVDF), epoxies), dahaarka budada ah iyo filimada laminateerka.
Rinjiga dareeraha ah ayaa ka badan 90% dahaarka loo isticmaalo birta hore loo dejiyay. Filimada waxaa badanaa lagu isticmaalaa halka tayada quruxda badan ee loo baahan yahay. Kala duwanaanshaha dhumucda filimka, midabada iyo dhamaystirka (dhammaan, habaysan ama daabacan) waa la gaari karaa. Dahaarka budada waxaa lagu tilmaami karaa "rinji adag" kaas oo la dhalaali karo si loo sameeyo filim joogto ah oo ka sarreeya substrate-ka. Nooc kasta oo dahaar ah ayaa leh faa'iidooyin gaar ah, ha ahaato dhumucdiisuna, dhalaalid, qallafsanaan, dabacsanaan, adkeysiga cimilada adag ama iska caabinta weerarka kiimikada. Doorashada nidaamka ugu habboon waa in lagu saleeyaa isticmaalkeeda iyo waxqabadka la filayo.
