Urupapuro rwometseho impapuro
Urupapuro rushyizweho ni ukwirinda kwangirika hejuru yicyuma cyinshi kandi byongera ubuzima bwa serivisi.
Ubuso bwa plaque yibyibushye busizwe hamwe na zinc metallic.
Ubu bwoko bwa galvanised ubukonje buzengurutse urupapuro rwitwa urupapuro.
Ibicuruzwa bishyushye bishyushye bikoreshwa cyane cyane mu nganda zikora inganda, nko kubaka ubwubatsi, inganda zoroheje, trolleys, ubuhinzi, ubworozi n’uburobyi, na serivisi z’ubucuruzi.
Muri byo, inganda zubaka zikwiranye n’umusaruro w’inganda zidashobora kwangirika hamwe n’ibisenge byamabara yamabara hamwe nigisenge cyamazu yinyubako;
inganda zibyuma zirayikoresha mugukora ibikoresho byo murugo, chimneys sivile, ibikoresho byigikoni, nibindi,
n'inganda zikora ibinyabiziga zikwiranye no gukora imodoka.
Ibirwanya ruswa.
Ubuhinzi, ubworozi n'uburobyi bukoreshwa cyane cyane kubika ibiryo no gutwara,ibiryo by'inyama n'ibicuruzwa byo mu nyanja bikonjesha n'ibikoresho byo gutunganya, n'ibindi.serivisi z'ubucuruzi zikoreshwa cyane cyane mugutanga ibikoresho, kubika no gupakira ibikoresho.
Urupapuro rutagira umuyonga rwerekana ibyuma birwanya ibyuma byangirika cyane nka gaze, amavuta,amazi n'ibinyabuzima byangiza ibintu nka acide, alkalis n'umunyu.
Azwi kandi nk'icyuma kitagira umwanda hamwe n'ibyuma birwanya aside.
Mubikorwa bimwe, ibyuma birwanya ibintu byangirika mubisanzwe byitwa ibyuma bidafite ingese,mugihe ibyuma bidashobora kwihanganira ibintu byitwa aside irwanya aside.
Ukurikije uburyo bwayo, ibyuma bidafite ingese mubisanzwe bigabanyamo ibyuma bya austenitis, ibyuma bya ferritic,ibyuma bya ferritic, ibyuma bya ferritic metallographic (duplex) icyuma kidafite ibyuma hamwe no gutura icyuma gikomeye.
Byongeye kandi, irashobora kwigabanyamo plaque ya chromium idafite ibyuma, chromium-nikel isahani idafite ibyuma na chromium manganese azote ya plaque.
Impamvu
Kurwanya ruswa yamashanyarazi yamashanyarazi agabanuka hamwe no kwiyongera kwa karubone.
Kubwibyo, karubone yibyuma byinshi bidafite ibyuma ni bike, ntibirenza 1,2%,na Wc (ibirimo karubone) yibyuma bimwe na bimwe biri munsi ya 0.03% (urugero, 00Cr12).
Urufunguzo rwa aluminiyumu ivanze muri plaque idafite ibyuma ni Cr (chromium).
Gusa iyo amazi ya Cr arenze agaciro runaka, ibyuma birwanya ruswa.
Kubwibyo, muri rusange Cr (chromium) amazi yibyuma bidafite ibyuma byibuze 10.5%.
Isahani idafite ibyuma nayo irimo ibintu nka Ni, Ti, Mn, N, Nb, Mo na Si.
Urupapuro rwuma rutagira umuyonga ntirworoshye gutera ruswa, kwangirika kwangirika, ingese, cyangwa kwangirika.
Mu byuma bigize ibikoresho byo gukoresha mu buhanga, ibyuma bidafite ingese nabyo ni kimwe mu bikoresho fatizo bifite imbaraga zo kwikuramo cyane.
Nka plaque idafite ibyuma ifite imbaraga zo kurwanya ruswa.
Irashobora gutuma abanyamuryango bubaka bakomeza burundu guhuza ibishushanyo mbonera byubwubatsi.
Chromium irimo ibyuma bitagira umuyonga nabyo bigira ingaruka zikomeye no guhindagurika cyane,bikaba byoroshye kubyara, gutunganya no gukora ibice, hamwe nibikenewe abubatsi n'abashushanya muri rusange barashobora gutekereza.
