Abathengi abaningi bacabanga ukuthi intambo yensimbi eqinile iwubufakazi bokugqwala ngokuphelele{0}. Lokhu kuwukungaqondi okuvamile.
Intambo yocingo lwensimbi ekhangayoimbozwe ngengqimba ye-zinc ngokushisa-i-dip galvanizing noma i-electro-galvanising. Isendlalelo se-zinc sisebenza njengokuzihlukanisa ngokomzimba futhi sinikeza isivikelo se-anode somhlatshelo ukuze kubambezeleke ukugqwala kwensimbi. Kodwa-ke, ukugqwala kubambezela kuphela ukugqwala, akukwazi ukuvimbela ukugqwala unomphela.
Izimbangela eziyinhloko zokugqwala entanjeni yocingo lukathayela
Ukulimala kwesendlalelo seZinc
Ukungqubuzana, umthelela, ukugoba kanye nokuklwebheka okucijile ngesikhathi sokufakwa nokusebenza kuzoguga ukunamathela kwe-zinc. Uma insimbi yesisekelo sembulwa, amabala okugqwala azokwakheka ngokushesha.
Indawo yesevisi enokhahlo
Ukuchayeka-isikhathi eside emanzini emvula, umswakama ophezulu, isifutho sikasawoti (izindawo ezisogwini), i-asidi noma amanzi angcolile ane-alkali kusheshisa i-zinc oxidation. Ukugqwala okumhlophe (i-zinc oxide) kuqala kuvela phezulu, bese kusakazeka ukugqwala okubomvu.
Ikhwalithi embi yokufaka uthayela
I-zinc ezacile, engalingani noma enezimbotshana azikwazi ukunikeza-ukuvikelwa kwesikhathi eside. Intambo ye-Electro-intambo ye-galvanized inesendlalelo se-zinc esizacile kanye nokungagqwala okubuthakathaka uma kuqhathaniswa nohlobo olushisayo{3}}lokucwilisa.
Impilo ende yesevisi ngaphandle kwesondlo
Ukuguga kwemvelo kongqimba lwezinc phakathi neminyaka kancane kancane kulahlekelwa ukusebenza kokuvikela.
Umehluko: Ukugqwala Okumhlophe vs Ukugqwala Okubomvu
- Ukugqwala okumhlophe: I-oxidation ye-zinc enamathela ngokwayo. Akusho ukuthi insimbi yensimbi yangaphakathi igqwalile. Ukuhlanza okufika ngesikhathi kanye nokwelashwa{2}}okuqeda ukubola kunganweba impilo yesevisi.
- Ukugqwala okubomvu: I-iron oxide ye-substrate yensimbi. Kubonisa ukuthi ungqimba lwezinc luhlulekile, futhi intambo yocingo iqala ukugqwala kwesakhiwo, okuthinta amandla okuqina nokuphepha.
Iziphakamiso ezisebenzayo zokunciphisa ukugqwala
- Khetha-intambo yensimbi yokucwilisa eshisayo yezimo zokusebenza zangaphandle, zasolwandle nezinomswakama.
- Gwema ukungqubuzana nobudlova ngesikhathi sokuthutha, ukufakwa kanye nokusebenzisa.
- Njalo hlola ubuqotho be-surface coating; lungisa imihuzuko ngokushesha.
- Faka amafutha avimbela{0}ukugqwala afanele intambo yocingo ngezikhathi ezihleliwe.
- Gcina endlini ezindaweni ezomile nezingena umoya uma ingenzi lutho.
Intambo yocingo lwensimbi ekhangayoizogqwala ekugcineni. I-galvanized coating ivikela{1}}ukugqwala, ayivimbeli ukugqwala unomphela. Indawo yesevisi, ikhwalithi yokumboza kanye nokugcinwa kwansuku zonke kunquma ngokuqondile ukuthi ukugqwala kuvela ngokushesha kangakanani.
Uma udidekile mayelana nokukhetha intambo-efanele yokugqwala yamaphrojekthi asogwini, anomswakama noma angaphandle, thumela izimo zakho zokusebenza kanye nemingcele edingekayo kithi.Thola ukubonisana kwamahhala kwezobuchwepheshe kanye nekhotheshini manje!
