Amakuru

Kuvura hejuru bikoreshwa mugukora ibyuma isahani. Icyumaisahani yinjijwe mumashanyarazi ya chromic kugirango ikore firime yoroheje hejuru ya zinc. Nubwo firime ya chromate yamenetse gato, chromate hafi yikiruhuko izashonga mumazi hanyuma ikusanyirize kuruhuka hanyuma ikore firime nshya. Ibi birinda kubyara ingese zera. Shira amavuta kumashanyaraziisahani kugirango wirinde guhura hagati yumuyaga na zinc. Buri gihe menya ko amavuta agomba guhanagurwa hejuru yicyumaisahani mbere yo gushushanya. Niba ibyuma bya galvanisisahani ni Kuri Gukoresha Ibishushanyo, Birashobora kuvurwa nuruhu * rwariye. * Kurya bizakomeza gushikama hejuru yicyumaisahani, gukora ubuso bworoshye, buzengurutse buzatanga ikirenge cyiza kugirango irangi ryubahirize.

Icyuma isahani bigomba kubikwa ahantu hafite umwuka mwiza nyuma yumusaruro. Cyangwa ukoreshe icyuma cyumye cyangwa cyumye kugirango wirinde ubukonje mugihe cyubushuhe bwinshi kandi itandukaniro rinini hagati yubukonje nubushyuhe. Muri iki gihe, Wan ntishobora gutose no kwibizwa. Niba itose ikime cyangwa amazi, igomba gukama, kandi paki irashobora gupakururwa no guhuha ukoresheje umufana. Ubitswe ahantu hafite umwuka mwiza, niba itandukaniro ryubushyuhe hagati yubukonje nubushyuhe, byoroshye kugaragara aho ikime kigomba kwirindwa.

(1) Ibyuma isahani gukora ibintu bimwe na bimwe byo kuvura, nko kureka ubuso bwayo bukora firime yoroheje, bityo, kugirango ibe yubatswe neza, kugirango yorohereze ubuso bwakazi ko gutera amarangi.

(2) Shyira ibyuma bitagira umwanda isahani ahantu hakonje kandi hafite umwuka, irinde ubushuhe nimvura, nibiba ngombwa, harashobora gufatwa ingamba zo kurinda ubuso.
