◉Muri societe igezweho, ibyuma bidafite ingese byahindutse ibintu bisanzwe kandi byingenzi bikoreshwa cyane mubwubatsi, gukora no mubuzima bwa buri munsi. Hariho ubwoko bwinshi bwibyuma bidafite ingese, harimo moderi zisanzwe nka 201, 304 na316.
Ariko, kubadasobanukiwe nimiterere yibikoresho, biroroshye kwitiranya itandukaniro riri hagati yizi ngero. Iyi ngingo izasobanura itandukaniro riri hagati yicyuma kitagira umwanda 201, 304 na 316 kugirango gifashe abasomyi kumva neza imiterere itandukanye yibikoresho byuma kandi bitange ibitekerezo bimwe byo kugura ibyuma bitagira umwanda.
◉Ubwa mbere, itandukaniro ryimiterere yimiti
Ibigize imiti yibyuma bitagira umwanda nibintu byingenzi muguhitamo imikorere n'ibiranga.Ibyuma bitagira umwanda 201, 304 na 316 hari itandukaniro rigaragara mubigize imiti. Ibyuma bitagira umwanda 201 birimo chromium 17.5% -19.5%, nikel 3,5% -5.5%, azote na 0.1% -0.5%, ariko nta molybdenum.
Ku rundi ruhande, ibyuma bitagira umwanda 304, birimo chromium 18% -20%, nikel 8% -10.5%, kandi nta azote cyangwa molybdenum. Ibinyuranye, ibyuma bitagira umwanda 316 birimo 16% -18% chromium, 10% -14% nikel, na 2% -3% molybdenum. Uhereye ku bigize imiti, ibyuma bitagira umwanda 316 bifite imbaraga zo kurwanya ruswa no kurwanya aside, bikwiriye gukoreshwa ahantu runaka bidasanzwe kuruta ibyuma bitagira umwanda 201 na 304.
◉Icya kabiri, itandukaniro ryo kurwanya ruswa
Kurwanya ruswa nikintu cyingenzi cyerekana imikorere yicyuma. Ibyuma bitagira umwanda 201 bifite imbaraga zo kurwanya ruswa nyinshi za acide kama, acide organique hamwe n ibisubizo byumunyu mubushyuhe bwicyumba, ariko bizangirika mubidukikije bikomeye bya alkaline. Ibyuma bitagira umwanda 304 bifite imbaraga zo kurwanya ruswa kandi birakwiriye kubidukikije muri rusange.
Ku rundi ruhande, ibyuma bitagira umwanda 316, birusha imbaraga kurwanya ruswa, cyane cyane mu bidukikije bya aside ndetse n’ubushyuhe bwo hejuru cyane hamwe no kurwanya ruswa, akenshi bikoreshwa mu miti, mu nyanja n’ibindi bikorwa. Kubwibyo, mugihe ugura ibikoresho byuma bidafite umwanda, nibyingenzi guhitamo icyitegererezo gikwiye ukurikije imikoreshereze yihariye yibidukikije.
◉Icya gatatu, itandukaniro mumiterere yubukanishi
Imiterere yubukorikori bwibyuma bitagira umwanda birimo ibipimo nkimbaraga, guhindagurika no gukomera. Muri rusange, imbaraga zicyuma zitagira umwanda 201 ziri hejuru gato ugereranije nicyuma 304, ariko kiri munsi cyane yicyuma kitagira umwanda 316.Icyuma kitagira umwanda 201 na 304 gifite ihindagurika ryiza, byoroshye gutunganya no kubumba, bikwiranye nibikoresho bimwe gutunganya imikorere isabwa mubihe byinshi.
Imbaraga zisumba ibyuma bitagira umwanda 316, ariko kandi ifite imbaraga zo kwihanganira kwambara no kurwanya ubukana, bikwiranye no guhangana nimbaraga nyinshi hamwe nubushyuhe bwo hejuru bukora. Kubwibyo, mugihe uhisemo ibikoresho byuma bidafite umwanda, ugomba guhitamo neza ukurikije ibisabwa byubukanishi hamwe nikoreshwa ryibidukikije.
◉Icya kane, itandukaniro ryibiciro
Hariho kandi itandukaniro ryibiciro byibyuma bitagira umwanda 201, 304 na 316. Muri rusange, igiciro cyibyuma bitagira umwanda 201 ni gito, kandi bihendutse. Igiciro cyibyuma bitagira umwanda 304 birasa nkaho biri hejuru, ariko kubera uburyo bwinshi bwakoreshwa hamwe nibikorwa byiza muri rusange, biracyari imwe mubintu bisanzwe byuma bidafite ingese kumasoko.
◉ Ibyuma bitagira umwanda 316 birahenze cyane kuberako birwanya ruswa kandi birwanya imashini, kandi birakwiriye kumirima idasanzwe isaba ibintu byinshi. Kubwibyo, mugihe uguze ibikoresho byuma bidafite umwanda, ugomba gutekereza kubintu nkibikorwa bifatika na bije.
Nkumuntu utanga ibikoresho byibyuma bidafite umwanda, Shanghai Qinkai Industry Co.
Uru ruganda rwashinzwe mu 2014, kandi nyuma yimyaka yiterambere, rwahindutse isosiyete ihuza igurishwa ryamasahani, tebes hamwe na profile.
Gukurikiza ihame ryabakiriya mbere,Qinkaiyiyemeje guha abakiriya ibikoresho byo mu rwego rwo hejuru bidafite ibyuma na serivisi nziza!
