Umgaqo we-deplating ye-Resist ityuwa S kunye neempembelelo zayo ziyafundwa, kwaye i-fenton oxygen / indlela yekhemikhali yamkelwa ukujongana nenkunkuma ekhuphayo equlethe.Nchasa u-S. Iziphumo zibonisa ukuba indlela inokususa i-70% yechroma.

Nchasa u-Syi // nitrate // ji// Ben // .. Njengombindi wedayi, isulfure // i-asidi // i-sodium isetyenziswa ngokuqhelekileyo njenge-arhente yokukhusela idayi kunye ne-orenji yokukhusela i-agent, kwaye isetyenziswa ngokubanzi njenge-electroplating nickel remover.Nchasa u-Sinokunyibilikisa i-coating, kodwa ayiyi kutshabalalisa i-substrate, kwaye inefuthe lokukhusela kwi-substrate. Inkqubo yokulungiswa kwayo imalunga noku kulandelayo:

 

I-C6H6 -- HNO3.H2SO4 i-nitrate edibeneyo -- nitrate. I-Base Ben -- trioxygen. Isulphurization. Sulfontion -- ityuwa yokuthintela.

 

1. Umgaqo-siseko we-deplating anti-dayi yetyuwa S nge-electroplating

 

Kwishishini le-electroplating, ngakumbi kumashishini okufakwa kwesinyithi, ityuwa ye-anti-dayi S isetyenziselwa ikakhulu i-nickel, igolide kunye nezinye izinto zokubeka, kodwa isetyenziswa ngokubanzi kwinkqubo yangaphambili yombane.

 

Okwangoku, eyona nkqubo iphambili yokulahla: i-nitrate edibeneyo. Indlela ye-Acid, indlela ye-electrolysis, ityuwa ye-anti-dayi ye-S. Phakathi kwabo, umehluko phakathi kwe-QING kunye ne-non-Qing deplating iinkqubo kwi-anti-dye yetyuwa ye-S indlela yokuba ingaba i-NaCN isetyenziswe njenge-agent eyinkimbinkimbi. Ke ngoko, ityuwa echasene nedayi S iseyinxalenye esebenzayo yazo zonke iintlobo ze-nickel zokususa ii-agent kwimarike okwangoku.

 

1, deplating agent izithako

 

2, iimpembelelo ze-electroplating anti-daying salt S

 

Umbala wesisombululo se-deplating ufana namanzi amdaka aqukethe i-chromium ephezulu, kwaye isisombululo se-deplating siqulethe i-concentration ephezulu ye-QING, ekulula ukuyikhupha ngempazamo emanzini amdaka aqukethe i-chromium. Amanzi, okubangela. UMlawuli /.. ngoko.

 

Ekubeni umbala obangelwaNchasa u-SKunzima kakhulu ukuyisusa, ayinakususwa ngekhemikhali yokucocwa kwamanzi amdaka e-electroplating njengeklorini eqhelekileyo kunye nendlela yeoksijini, okukhokelela kumbala otyheli wamanzi amdaka, nto leyo echaphazela ukukhutshelwa kwamanzi kwaye inyusa umthwalo wenkqubo yonyango lwe-membrane kwindawo ephakathi. ukusetyenziswa kwakhona kwamanzi. Isiphumo somthubi okhanyayo siye sibe khaphukhaphu kwiimeko ezineasidi, sibemnyama kwiimeko ezingathathi hlangothi kunye ne-alkaline, kwaye sibe mnyama ngombala ukusuka kumthubi ukuya kubomvu emva kokuvezwa kokukhanya.

 

3. Unyango lwenkunkuma >/ amanzi anetyuwa echasene nedayi

 

Amanzi kufuneka aqokelelwe ngokwahlukileyo kwaye aphathwe ngokwahlukileyo. Okwangoku, azikho iindlela ezininzi ezisebenzayo zokunyanga amanzi, njenge-oxygen eqhelekileyo / i-chlorination. I-asidi ye-sodium, i-oxygen, njl. ayikwazi ukuvula i-nitrate. UBen ukhala kwisiseko sikaBen kunye noBenamine. I-carbon adsorption esebenzayo kunye neendlela zokumanzisa okudadayo azikwazi ukususa i-nitrate. I-Base Ben kunye ne-benamine, kodwa ngesulfure. I-asidi ye-Ferrous iyakwazi ukufihla inxalenye yombala, kodwa kuya kubakho umbala, ukuba amanzi awakhulu, anokuhlanjululwa ngamanzi okukhutshwa emva kokukhutshwa.

 

Inkqubo ye-Fenton oxidation yayisetyenziselwa ukuphatha inkunkuma./ amanzi, kunye nesiphumo sokususa umbala we-H2O2 yaphononongwa. Yonke le nkqubo yahlulwe ngamanqanaba amabini: pretreatment kunye Fenton oxygenation.
