Umgomo wokuchithwa kwe-Resist salt S kanye nomthelela wawo kuyacwaningwa, bese kwamukelwa indlela ye-fenton oxygen/chemical ukuze kubhekwane nokukhipha imfucuza equkethe.Melana no-S. Imiphumela ibonisa ukuthi indlela ingasusa i-chroma engu-70%.
Melana no-Syi-// nitrate //ji// Ben // .. Njengesiphakathi samadayi, isibabule // i-asidi // i-sodium ivame ukusetshenziswa njenge-ejenti yokuvimbela udayi kanye ne-ejenti yokuvikela ewolintshi, futhi isetshenziswa kabanzi njengesikhiphi se-nickel se-electroplating.Melana no-Singancibilikisa i-coating, kodwa ingagqwali i-substrate, futhi inomphumela wokuvikela ku-substrate. Inqubo yayo yokulungiselela icishe ihambe kanje:
C6H6 -- HNO3.H2SO4 i-nitrate exubile -- nitrate. I-Base Ben - i-trioxygen. I-sulphurization. I-sulfonation - usawoti wokuvimbela.
1. Isimiso sokususa usawoti we-anti-dye S nge-electroplating
Embonini ye-electroplating, ikakhulukazi emabhizinisini e-metal plating, usawoti we-anti-dye S usetshenziselwa ikakhulukazi i-nickel, igolide nokunye ukucwenga, kodwa futhi usetshenziswa kabanzi enqubweni ye-pre-electroplating.
Njengamanje, inqubo eyinhloko ye-deplating: i-nitrate exutshwe. Indlela ye-Acid, indlela ye-electrolysis, i-anti-dayi kasawoti S indlela. Phakathi kwazo, umehluko phakathi kwezinqubo ze-QING kanye ne-non-Qing deplating ku-anti-dye kasawoti S indlela ukuthi ngabe i-NaCN isetshenziswa njenge-ejenti eyinkimbinkimbi. Ngakho-ke, usawoti we-anti-dye S useyingxenye ephumelelayo yazo zonke izinhlobo zama-ejenti okukhipha i-nickel emakethe okwamanje.
1, izithako ze-ejenti deplating
2, umthelela we-electroplating anti-dyeing usawoti S
Umbala wesisombululo sokususa ufana nowamanzi angcolile aqukethe i-chromium ephezulu, futhi isixazululo sokususa siqukethe ukugcwala okuphezulu kwe-QING, okulula ukukhishelwa ngephutha emanzini alahlwayo aqukethe i-chromium. Amanzi, okuholela ku. Umqondisi /.. ngakho.
Kusukela umbala obangelwaMelana no-SKunzima kakhulu ukukususa, akukwazi ukususwa ngamanzi angcolile e-electroplating amakhemikhali anjenge-chlorine evamile kanye nendlela ye-oksijini, okuholela kumbala ophuzi ojulile wamanzi angcolile, okuthinta ukuchithwa kwamanzi futhi kwandisa umthwalo wesistimu yokwelapha ulwelwesi oluphakathi nendawo. ukusetshenziswa kabusha kwamanzi. Okuphuzi okukhanyayo okuholelayo kuba lula ezimeni ezine-acidic, kuba mnyama ezimeni ezimaphakathi ne-alkaline, futhi kube mnyama ngombala ukusuka kokuphuzi ukuya kokubomvu ngemva kokuchayeka ekukhanyeni.
3. Ukwelashwa kwemfucuza >/ amanzi aqukethe usawoti ophikisana nodayi
Amanzi kufanele aqoqwe ngokwehlukana futhi aphathwe ngokwehlukana. Njengamanje, azikho izindlela eziningi ezisebenzayo zokwelapha amanzi, njenge-oxygen evamile/i-chlorination. I-sodium acid, umoya-mpilo, njll. ayikwazi ukuvula i-nitrate. U-Ben ukhala ku-base Ben no-Benamine. I-carbon adsorption ecushiwe nezindlela zemvula ezintantayo azikwazi ukususa i-nitrate. I-Base Ben ne-benamine, kodwa ngesibabule. I-asidi ene-ferrous ingakwazi ukufihla ingxenye yombala, kodwa kuyoba khona umbala, uma amanzi engenkulu, angahlanjululwa ngamanzi okukhipha ngemva kokukhishwa.
Inqubo ye-Fenton oxidation yasetshenziswa ukwelapha udoti./ amanzi, futhi umphumela wokukhipha umbala we-H2O2 wacwaningwa. Yonke inqubo ihlukaniswe izigaba ezimbili: pretreatment kanye Fenton oxygenation.
3.1 Izakhiwo zesixazululo se-deplating
3.2 Ukwelashwa ngaphambi kwesikhathi
Njengokususa imfucuza /. Amanzi aqukethe inani eliphezulu le-QING, adinga ukuvuselelwa. Yonke inqubo ihlukaniswe izigaba ezimbili:
1) I-QING yephulwe indlela ye-oxygen chloride.
2) PAC, PAM flocculation imvula.
3.3 I-Fenton oxidation
Imiphumela ibonisa ukuthi indlela ye-Fenton oxidation ingasusa cishe u-70% we-chroma, nezindlela ezihlukahlukene ezithuthukisiwe ze-Fenton oxidation, ezifana namafayili ensimbi yokucwenga yethusi esikhundleni sesibabule. I-asidi ene-ferrous njenge-catalyst ingathuthukisa ukusebenza kahle kwe-catalytic, kodwa ayikwazi ukuyisusa ngokuphelele, ngakho-ke imfucuza ye-deplating equkethe usawoti we-anti-dye S /. Amanzi aseyinselelo.
4 isiphetho
Deplating udoti kuhlanganise Electroresist S? / Umbala wamanzi kunzima kakhulu ukuwukhipha, okuyisici esiyinhloko esenza ukungcola kuguquke kubephuzi, futhi umbala ujule ngemva kokukhanya, okuthinta kakhulu izinga lamanzi/amanzi aphumayo. Ebukhoneni benombolo enkulu ye-ion eyinsimbi ukumboza ingxenye yombala, kodwa izobuyiselwa esimweni sombala, usebenzisa inqubo ye-fenton oxidation ingasusa u-70% wombala, namanje ayikwazi ukususa ngokuphelele, umoya-mpilo ophezulu / ubuchwepheshe kanye izindleko eziphakeme zenani langempela lokusetshenziswa ziphansi, ngakho-ke ukuthola ezinye iziphehli kanye nobuchwepheshe bokucwenga obuhlukile ukuze uthole isiqondiso sokuxazulula inkinga.
