Ihame ryo gukuraho umunyu S Kurwanya umunyu S ningaruka zaryo birigwa, kandi hakoreshejwe uburyo bwa fenton ogisijeni / imiti ikoreshwa kugirango ikemure imyanda yangirika irimoKurwanya S.. Ibisubizo byerekana ko uburyo bushobora gukuraho chroma 70%.
Kurwanya S.ni // nitrate // ji // Ben // .. Nkurwego rwagateganyo rwamabara, sulfure // aside // sodium ikunze gukoreshwa nkumuti wo gukumira amarangi hamwe nu muti urinda amacunga, kandi ikoreshwa cyane nko gukuraho nikel.Kurwanya S.Irashobora gushonga igifuniko, ariko ntigishobora kwangiza substrate, kandi igira ingaruka zo gukingira substrate. Igikorwa cyacyo cyo gutegura ni hafi kuburyo bukurikira:
C6H6 - HNO3.H2SO4 ivanze nitrasi - nitrate. Base Ben - trioxygene. Amashanyarazi. Sulfonation - umunyu wo kwirinda.
1. Ihame ryo kwerekana umunyu urwanya irangi S ukoresheje amashanyarazi
Mu nganda zikoresha amashanyarazi, cyane cyane mu nganda zikozwe mu byuma, umunyu urwanya irangi S ukoreshwa cyane cyane kuri nikel, zahabu n’andi masahani, ariko kandi ukoreshwa cyane mu nzira yo kubanziriza amashanyarazi.
Kugeza ubu, inzira nyamukuru yo kwerekana: nitrate ivanze. Uburyo bwa acide, uburyo bwa electrolysis, anti - irangi ryumunyu S. Muri byo, itandukaniro riri hagati ya QING nuburyo butari Qing bwerekana uburyo bwo kurwanya umunyu S ni ukumenya niba NaCN ikoreshwa nkibikoresho bigoye. Kubwibyo, umunyu urwanya irangi S uracyari ikintu cyiza cyubwoko bwose bwo gukuraho nikel ku isoko muri iki gihe.
1, kwerekana ibikoresho bya agent
2, ingaruka za electroplating anti-irangi umunyu S.
Ibara ryumuti ugabanuka urasa nuw'amazi menshi ya chromium arimo amazi menshi, kandi igisubizo cyo gukuramo kirimo ubwinshi bwa QING, byoroshye koherezwa kwibeshya mumazi ya chromium arimo imyanda. Amazi, bivamo. Umuyobozi / .. nuko.
Kuva ibara ryatewe naKurwanya S.biragoye cyane kuyikuramo, ntishobora gukurwaho no kwifashisha imiti y’amazi y’amashanyarazi nka chlorine isanzwe nuburyo bwa ogisijeni, bikavamo ibara ryumuhondo rikomeye ryimyanda, bigira ingaruka kumaraso kandi bikongera umutwaro wa sisitemu yo kuvura membrane kubiciriritse kongera gukoresha amazi. Umuhondo wijimye uvuyemo uba woroshye mubihe bya acide, wijimye mubihe bidafite aho bibogamiye na alkaline, kandi wijimye wijimye kuva umuhondo ukageza umutuku nyuma yumucyo.
3. Gutunganya imyanda> / amazi arimo umunyu urwanya irangi
Amazi agomba gukusanywa ukundi kandi akavurwa ukwayo. Kugeza ubu, nta buryo bwinshi bufatika bwo gutunganya amazi, nka ogisijeni isanzwe / chlorine. Acide Sodium, ogisijeni, nibindi ntibishobora gufungura nitrate. Ben avuza impeta muri Ben na Benamine. Gukoresha karubone ikora hamwe nuburyo bwimvura igwa ntishobora gukuraho nitrate. Base Ben na benamine, ariko hamwe na sulfure. Acide ferrous irashobora guhisha igice cyamabara, ariko hazabaho ibintu byamabara, niba amazi atari manini, arashobora kuvangwa namazi asohoka nyuma yo gusohoka.
Uburyo bwa okiside ya Fenton bwakoreshejwe mugutunganya imyanda./ amazi, ningaruka zo gukuraho amabara ya H2O2 yarizwe. Inzira yose igabanijwemo ibyiciro bibiri: kwitegura na ogisijeni ya Fenton.
3.1 Ibyiza byo gukuraho igisubizo
3.2
Nkugukuraho imyanda /. Amazi arimo ubunini bwinshi bwa QING, bigomba kubanza gutegurwa. Inzira yose igabanijwemo ibyiciro bibiri:
1) QING yavunitse hakoreshejwe uburyo bwa ogisijeni chloride.
2) PAC, imvura igwa ya PAM.
3.3 Okiside ya Fenton
Ibisubizo byerekana ko uburyo bwa okiside ya Fenton bushobora gukuraho hafi 70% ya chroma, hamwe nuburyo butandukanye bwatezimbere okiside ya Fenton, nkumuringa usize ibyuma aho kuba sulferi. Acide Ferrous nka catalizator irashobora kunoza imikorere ya catalitiki, ariko ntishobora kuyikuraho burundu, bityo imyanda igabanuka irimo umunyu urwanya irangi S /. Amazi aracyari ingorabahizi.
4 umwanzuro
Gukuraho imyanda harimo na Electroresist S? / Ibara ryamazi biragoye cyane kuyikuramo, nicyo kintu nyamukuru gitera imyanda guhinduka umuhondo, kandi ibara ryimbitse nyuma yumucyo, bigira ingaruka zikomeye kumiterere yamazi / amazi. Imbere yumubare munini wa ion ferrous kugirango utwikire igice cyamabara, ariko uzasubizwa mubintu byamabara, ukoresheje inzira ya okiside ya fenton irashobora gukuraho 70% yibara, ntushobora gukuraho burundu, ogisijeni mwinshi / ikoranabuhanga hamwe na igiciro kinini cyo gukoresha agaciro nyako ni muke, kugirango rero ushakishe ubundi reagent hamwe nubundi buryo bwa tekinoroji yo gukoresha icyerekezo kugirango gikemure ikibazo.
