Itheyiphu ehlanganisiweiqala ekuqaleni kwekhulu le-19. Ngaleso sikhathi, ngokuthuthuka kweNguquko Yezimboni, ukukhiqizwa nokusetshenziswa kwensimbi kwanda ngokushesha. Ngenxa yokuthi insimbi yengulube nensimbi kuvame ukugqwala lapho kuvezwa umswakama nomoya-mpilo, ososayensi baqala ukuhlola izindlela zokuvimbela ukugqwala.
Ngo-1836, isazi semithi saseFrance u-Antoine Henri Becker saqala ukuphakamisa umqondo wokumboza i-zinc phezu kwensimbi noma insimbi ukuze kuvinjelwe ukugqwala. Le ndlela yaziwa ngokuthii-hot dip galvanizingNgokuthuthuka kwalobu buchwepheshe, i-galvanized tape iye yakhiqizwa kabanzi futhi yasetshenziswa kancane kancane.
Ekhulwini lama-20, ngentuthuko eqhubekayo yobuchwepheshe bokufaka i-galvanizing, izinqubo ezahlukahlukene ezifana nokufaka i-electroplating kanye nokufaka i-hot plating ziye zavela ngokulandelana, ngakho ukusebenza kahle kokukhiqiza kanye nokusebenza kokulwa nokugqwala kwe-galvaning tape kuye kwathuthukiswa njalo. Lezi ntuthuko zikhuthaze ukusetshenziswa kabanzi kwe-galvaning tape ezimbonini eziningi ezifana nokwakha, izimoto, kanye nezinto zasekhaya, okwakha imakethe evuthiwe esiyibonayo namuhla.
Itheyiphu ye-galvanized isetshenziswe kabanzi ezimbonini eziningi ngenxa yokumelana kwayo okuhle nokugqwala kanye nokusebenza kahle. Emkhakheni wokwakha, i-galvanized tape isetshenziswa ezakhiweni zensimbi, ophahleni nasezindongeni, okungandisa impilo yesevisi ngempumelelo. Embonini yezimoto, i-galvanized tape isetshenziswakhiqiza izingxenye zomzimbaukuthuthukisa ukumelana nokugqwala nokuphepha. Izimboni zikagesi nezefenisha nazo ziyayisebenzisa njengento ebalulekile yokuthuthukisa ukuqina nobuhle bemikhiqizo yazo.
Esikhathini esizayo, ngemithethonqubo yezemvelo eqinile kanye nomkhuba wokwakha okuluhlaza kanye nentuthuko esimeme, isidingo semakethe samabhande e-galvanized kulindeleke ukuthi siqhubeke sikhula. Ukuthuthukiswa kwezinto ezintsha kanye nentuthuko yezobuchwepheshe kuzoqhubekathuthukisa ukusebenza kwetheyiphu ehlanganisiwefuthi yandise insimu yayo yokusetshenziswa. Ngakho-ke, amathuba okuthuthukiswa okuphelele kwetheyiphu ehlanganisiwe anethemba elikhulu, futhi isibe yinto ebaluleke kakhulu ezimbonini ezahlukahlukene.
