Kodi chitsulo cha galvanized chimachita dzimbiri? Kodi chingapewedwe bwanji?

Ngati zitsulo zomangiriridwa ndi galvanized ziyenera kusungidwa ndikunyamulidwa pafupi, njira zokwanira zodzitetezera ziyenera kutengedwa kuti dzimbiri lisachite. Njira zenizeni zodzitetezera ndi izi:

 

1. Njira zochizira pamwamba zingagwiritsidwe ntchito kuchepetsa kupangika kwa dzimbiri loyera pa chophimbacho.

Mapaipi opangidwa ndi galvanizing ndi zinthu zomangira zopanda kanthu zimatha kuphimbidwa ndi varnish yoyera pambuyo poika galvanizing. Zinthu monga waya, mapepala, ndi maukonde zimatha kupakidwa sera ndi mafuta. Pa zinthu zomangira za galvanizing zoviikidwa mu hot-dip, chithandizo chopanda chromium-passivation chingachitike nthawi yomweyo madzi atazizira. Ngati zinthu zomangira zitha kunyamulidwa ndikuyikidwa mwachangu, palibe chithandizo chomangika pambuyo pake. Ndipotu, kaya chithandizo cha pamwamba chikufunika kuti galvanizing iviikidwa mu hot-dip chimadalira mawonekedwe a zinthuzo komanso momwe zingasungidwire. Ngati pamwamba pa galvanizing payenera kupakidwa utoto mkati mwa miyezi isanu ndi umodzi, njira yoyenera yopangira galvanizing iyenera kusankhidwa kuti isakhudze kugwirizana pakati pa zinc ndi utoto.

 

2. Zigawo za galvanized ziyenera kusungidwa pamalo ouma, opumira bwino komanso ophimbidwa bwino.

Ngati mapaipi achitsulo ayenera kusungidwa panja, zigawozo ziyenera kukwezedwa kuchokera pansi ndikulekanitsidwa ndi mipata yopapatiza kuti mpweya uziyenda bwino pamwamba pa malo onse. Zigawozo ziyenera kupendekeka kuti madzi aziyenda bwino. Siziyenera kusungidwa pa nthaka yonyowa kapena zomera zomwe zikuwola.

 

3. Zigawo zophimbidwa ndi galvanized siziyenera kuyikidwa m'malo omwe zingagwere mvula, chifunga, madzi oundana, kapena chipale chofewa.

Litichitsulo chopangidwa ndi galvanizingNgati ikunyamulidwa ndi nyanja, siyenera kutumizidwa ngati katundu wa padenga kapena kuyikidwa m'malo osungira sitimayo, komwe ingakhudze madzi oundana. Pansi pa dzimbiri lamagetsi, madzi a m'nyanja amatha kukulitsa dzimbiri loyera. M'malo a m'nyanja, makamaka m'nyanja zotentha zomwe zili ndi chinyezi chambiri, kupereka malo ouma komanso malo abwino opumira mpweya ndikofunikira kwambiri.
