Nigute urwego rwa zinc rwo gusya ibyuma bisya?

Gusya ibyuma bya galvanised ni ubwoko bwibyuma kandi bikoreshwa cyane.Mugihe cyo gukora ibyuma byo gusya ibyuma, ibyuma bya zinc bizakorwa hejuru.Noneho, ni gute urwego rwa zinc rwakozwe?Iyo igikoresho cyo gusya ibyuma cyinjijwe muri zinc yashongeshejwe, kibanza gukora igisubizo gikomeye hamwe nicyuma (umubiri-hagati) hejuru.

Muri iki gihe, icyuma cyicyuma cyo gusya ibyuma gishonga hamwe na atome ya zinc muburyo bukomeye kugirango habeho kristu, atome ebyiri zicyuma zirahuzwa, kandi imbaraga za rukuruzi ziri hagati ya atome ni nto.Iyo zinc yuzuyemo igisubizo gikomeye, atome ebyiri za zinc nicyuma ziratatana hamwe, hamwe na atome ya zinc ikwirakwizwa muri matrike yicyuma ya materi yicyuma igenda muri matrike hanyuma igahinduka buhoro buhoro hamwe nicyuma.

Icyuma gikwirakwijwe mumazi ya zinc yashongeshejwe ikora intermetallic compound FeZn13 hamwe na zinc, ikarohama munsi yinkono ishyushye ya dip galvanizing, ari yo zinc.Iyo icyuma cyo gusya ibyuma gikuwe mumazi ya zinc, ubuso bugira urwego rwiza rwa zinc, arirwo rufunzo rwa mpandeshatu, kandi ibyuma birimo ntibirenza 0.003%.Igikorwa cyo gukora icyuma-zinc kivanze hagati yurwego, igihangano cyo gusya ibyuma kigizwe nicyuma-zinc alloy layer mugihe gishyushye cyane, bigatuma icyuma na zinc cyera bihujwe neza.
