Sharaxaad Gaaban:

Bandhiga alaabta:

Tuubbada galvanized-ku-kulul waa in ay samayso falcelinta birta dhalaalaysa iyo birta oo ay soo saarto lakab alloy ah, si matrixka iyo lakabka daahan la isku daro.Galvanizing kulul waa tuubada birta marka hore, si ay meesha uga saarto oksaydhka birta dushiisa ee tuubada birta, ka dib marka la qaado, iyada oo la marayo ammonium chloride ama zinc chloride xal ama ammonium chloride iyo zinc chloride haanta xal isku qasan, ka dibna loo diro kulul taangi dahaadhan.Galvanizing-ku-kululku wuxuu leeyahay faa'iidooyinka dahaarka labbiska ah, dhejinta xooggan iyo nolosha adeegga dheer.Falcelinta jidheed iyo kiimikaad ee isku dhafan waxay ku dhacdaa xalka dhalaalka ah ee tuubada birta galvanized kulul, samaynaysa daxal u adkaysta oo dhagan zinc-hal lakab oo daawaha birta ah.Lakabka Alloy wuxuu ku dhex milmay lakabka zinc saafiga ah iyo matrix tube bir ah, sidaa darteed iska caabbinta daxalka waa mid xoogan.

Dhuumaha birta alxanka galvanized ee gaarsiinta dareeraha cadaadiska hooseeya

1. Midaynta lakabka galvanized: muunada tuubada birta waxay si joogto ah ugu dhex jirtaa xalka copper sulfate muddo 5 jeer ah iyada oo aan casaan lahayn (midabka naxaasta)
2. tayada dusha sare: dusha sare ee tuubada birta galvanized waa inay lahaataa lakab galvanized dhamaystiran, ma jiraan dhibco madow oo aan la daboolin iyo goobooyin, oo u oggolow jiritaanka dusha yar ee qallafsan iyo buro zinc maxaliga ah.
3. Miisaanka lakabka galvanized: marka loo eego shuruudaha dalbadaha, tuubada birta galvanized waxaa loo isticmaali karaa sida cabbirka miisaanka lakabka zinc, iyo celceliska qiimaha waa inuusan ka yarayn 500g / mitir labajibbaaran, kaas oo muunad kasta uusan noqon doonin. in ka yar 480g / mitir murabac.
