Birta kulul ee la rusheeyey ee Zinc dahaarka leh ee galvanized Steel gariiradda xaashida

Qulqulka kulul ee substrate galvanized

Badeecada lagu helay dahaadhka dabiiciga ah ee xaashida birta ah ee kululaynta kulul waa xaashi midab leh oo midab leh. Marka laga soo tago saamaynta ilaalinta zinc, daaha organic ee dusha sare ee xaashida kulul ee galvanized galvanized midabka-dahaarka ah ayaa sidoo kale ka ciyaara doorka ilaalinta iyo ilaalinta, ka hortagga miridhku, iyo nolosha adeeggu way ka dheer tahay tan kululaynta kuleylka. xaashi galvanized. Maadada zinc ee substrate-ku-kulul-kuleelka galvanized guud ahaan waa 180g/m2 (laba-geesood), iyo qadarka ugu badan ee galvanized substrate-kuleelka galvanized ee dhismaha bannaanka waa 275g/m2.

Substrate-ka kulul ee Al-Zn

Xaashiyaha birta ah ee kulul ee galvanized (55% Al-Zn) waxaa loo isticmaalaa sida substrate-ka cusub ee daahan, iyo waxa ku jira aluminium iyo zinc inta badan waa 150g / ㎡ (laba dhinac). Iska caabbinta daxalka ee xaashida galvanized-ku-kululku waa 2-5 jeer ka xaashida galvanized-kuleelka ah. Isticmaalka joogtada ah ama joogtada ah ee heerkulka ilaa 490 ° C si xun uma uumi doono ama ma soo saari doono miisaan. Awoodda lagu muujinayo kulaylka iyo iftiinka waa 2 jeer ka badan birta galvanized ee kulul, iyo milicsiga ayaa ka weyn 0.75, taas oo ah qalab dhisme oo ku habboon badbaadinta tamarta.

Substrate-ka-galvanized

Waraaqda korantada-galvanized waxaa loo isticmaalaa sidii substrate-ka, iyo badeecada lagu helay dahaadhka rinjiga dabiiciga ah iyo dubista waa xaashi midab-dahaar leh oo koronto-galvanized ah. Sababtoo ah lakabka zinc ee xaashida elektiroonigga ah waa dhuuban, maadada zinc badanaa waa 20/20g/m2, markaa alaabtani kuma habboona isticmaalka. U samee gidaarada, saqafyada, iwm. bannaanka. Laakiin sababta oo ah muuqaalkeeda quruxda badan iyo waxqabadka habaynta aadka u fiican, waxaa inta badan loo isticmaali karaa qalabka guriga, maqalka, alaabta guriga, qurxinta gudaha, iwm.
