Ubunini bwa hot-dip galvanised layer ifite ibyiza byo gutwikira kimwe, gufatana gukomeye, ubuzima bumara igihe kirekire nibindi.Igiciro cyo gusya ni gito, hejuru ntago yoroshye cyane, kandi kurwanya ruswa kwayo ni bibi cyane kurenza iy'umuyoboro ushyushye.Igikorwa cyo gushiraho ubushyuhe-dip galvanizing layer ninzira yo gukora ibyuma bya zinc bivanze hagati ya matrix yicyuma nigitereko cyiza cya zinc.Icyuma cya zinc alloy layer gikozwe hejuru yumurimo wakazi mugihe cyo gushyushya-gushira, bigatuma guhuza neza hagati yicyuma na zinc nziza.Inzira irashobora gusobanurwa gusa nka: mugihe igihangano cyicyuma cyinjijwe muri zinc yashonze, ni sinc slag.Iyo igihangano cyakuwe mubisubizo byokwibizwa kwa zinc, hashyizweho urwego rwiza rwa zinc hejuru, aribwo kristu ya mpandeshatu.Ibyuma birimo ntabwo birenze 0.003%.
Umuyoboro ushushe ushyushye:
Nugukora icyuma gishongeshejwe hamwe na matrix yicyuma kugirango habeho urwego ruvanze, kugirango uhuze matrix hamwe nigitambaro.Gushyushya gushyushya ni ugutora icyuma mbere.Kugirango ukureho okiside ya fer hejuru yumuyoboro wibyuma, nyuma yo gutoragura, isukurwa muri chloride ya amonium cyangwa chloride ya zinc chloride cyangwa amonium chloride na zinc chloride ivanze nigitoro cyamazi, hanyuma ikoherezwa mukigega gishyushye cya galvanizing.Gushyushya ibishyushye bifite ibyiza byo gutwikira kimwe, gukomera hamwe no kuramba kuramba.Byinshi mubikorwa byo mumajyaruguru bifata inzira yo kuzunguruka umurongo wa galvanised kugirango wuzuze zinc.Icyuma cya matrike yicyuma hamwe nigisubizo cyashongeshejwe gifite reaction zingirakamaro kumubiri nubumashini, bigakora ruswa idashobora kwangirika kwangirika kwa zinc fer alloy layer ifite imiterere ihamye.Umuti wa alloy urahujwe hamwe na zinc nziza kandi matrike yicyuma.Kubwibyo, ifite imbaraga zo kurwanya ruswa.
