ni ikihe ? Icyuma cyibiryo
Ibiryo byo mu biribwa bidafite ishingiro bihuye na 'Repubulika y'Ubushinwa isanzwe GB9684 ' ibikoresho by'icyuma bidafite ishingiro. Ibirimo byo kuyobora Chromium ni munsi yurutaruro rusanzwe .
Ibipimo byerekana: Ibyuma byibiryo bitagira ingano bivuga igice gihuye nimashini zibiribwa ibiryo, nibiryo bigomba kuba byujuje ibisabwa mumutekano. Kuberako gukoresha ibiryo byinshi byibiryo bya acide , chromium ibyuma bidasubirwaho , ibyuma bidasubirwaho , bizashonga ibiciro bitandukanye bya chromium , uburozi; nibisabwa kugirango ugabanye ibikubiye mu Kige, Cadmium nandi Banyabuzima.
Itandukaniro riri hagati y'ibiryo by'ibiryo byanduye na 304 ibyuma 304 : Gukoresha ibicuruzwa byanduye bidafite ishingiro bikabije ry'ibyuma bikabije, birashobora kugirira nabi ubuzima bwa muntu. Kubwibyo, imisaruro yo gusiganwa kumeza igomba guhuza uburimbane hagati ya ruswa n'umutekano. Iyo nikel na chromium ari hejuru, imyigaragambyo ya ruswa yongerewe imbaraga, ariko umubare wa nikel na chromium . chromio na , nickel, nickel, kuyobora nicyuma cyimvura iremereye byagize uruhare runini
Kuki amahame yigihugu atagaragaza imipaka yo kwimuka ya Manganese?
Impamvu imwe nuko hiyongereyeho ibizwe na Mangane mubyuma bitagira ingano , ihohoterwa riterwa no kugaburira no gutera ingero naryo ryiyongera. Ibirimo Mangase imaze kugera kurwego runaka, ibicuruzwa ntibishobora gukoreshwa nkibiki cyangwa steel steel. Ariko no kurwego rwo hejuru rwa Manganese, mubisanzwe nta ngaruka zubuzima. Mugihe rero ibipimo byumutekano wibiribwa bidategeka urwego rwa Manganese, bagaragaza ko igice kinini cyibikoresho byibiribwa bigomba kuba bikozwe mubyuma bidafite ikibazo ukurikije ibipimo by'igihugu.
Bisanzwe
Ubwoko bwose bwo kubika ibiryo hamwe nimashini zitunganya ibiryo zigomba guhitamo ibyuma cyangwa Ferritique bidafite amanota (1CR18NI9, 0CR19NI9, 1CR18NI9, 1CR17NI2). Kugirango habeho igice cyo gutunganya igikoresho cyo gusya kirashobora kandi guhitamo ibyuma bya Martentianite (0CR13, 1CR13, 2cr13, 3cr13).
Ibipimo byihariye byumubiri na shobara ni nkibi bikurikira:
Ikintu Austenitic Steel Steel Ferritic Martensitic Ibyuma
Kuyobora (muri PB), MG / L 4% ACETIC ACMESTIon igisubizo ≤ 1.0 1.0.
Chromium (in cr), mg / l 4% acid acide kwigosha igisubizo ≤ 0.5
Nikel (muri NI), MG / L 4% acide acide ihinduka igisubizo ≤ 3.0 1.0.
Cadmium (muri CD), MG / L 4% acide acide ≤ 0.02 0.02.
Arsenic (AS), MG / L 4% acide acide acide ≤ 0.04 0.04.
Icyitonderwa: Ibintu byose bitetse kuri 30min hanyuma ubushyuhe bwicyumba kuri 24h.
Icyuma cyibiribwa Umuyoboro usudira ufite uburyo butandukanye, haba imbere no hanze yibisabwa. Kuvura imiyoboro ya Steel gusudira ni urufunguzo rwinshi, 0,5mm birashobora kandi kugera ku ngaruka zo gutakaza imbere.
Niba ari amanota yimyororo yicyuma adasukuye mubihe bisanzwe bigomba gutabwa imbere no hanze, icyarimwe Weld Gusya kandi gukomera . Gukenera kogosha imbere no hanze ntaho bihuriye nubunini bwurukuta, gusa nibikorwa byo gusaba. Urukuta rwurukuta ni ruto cyane mukwirukanwa imbere ntabwo ari ikibazo kinini cyane, kugirango ujugunye hanze gishobora kuba igipimo gito.
Niba ari umuyoboro usutswe , ntacyo bitwaye imbere no hanze. Reba kandi diameter yumuyoboro wawe. Umuyoboro udafite akamaro ntushobora gutabwa imbere. Ntushobora kuvuga ko urukuta rwurukuta rwa 0.5 ruto cyane. Kuberako niba ufite urukuta rwa metero 0.5 rwa metero imwe wa diameter, ntizizemezwa, ntizitonda. Ntabwo rero biterwa na diameter yumuyoboro wawe.
Ahari umuyoboro wawe uraremye cyane, urukuta rwurukuta runini cyane, kuko rwimbere kandi rwo hanze nukubona gukoresha ibisabwa, ntabwo bisabwa cyane, ntakintu gisabwa kugirango amafaranga atakenewe.
