Iyo musimboti wekudonhedza yeResist munyu S uye simba rayo rinodzidzwa, uye fenton okisijeni / makemikari nzira inotambirwa kubata neiyo deplating tsvina ine.Ramba S. Mhedzisiro yacho inoratidza kuti nzira yacho inogona kubvisa 70% chroma.
Ramba Sis // nitrate //ji// Ben //.. Sepakati pedhayi, sulfur // acid // sodium inowanzoshandiswa seyekudzivirira dhayi uye orange protective agent, uye inoshandiswa zvakanyanya se electroplating nickel remover.Ramba Sinogona kunyungudutsa iyo yekuputira, asi haina corrode iyo substrate, uye ine mhedzisiro yekudzivirira pane substrate. Kugadzirira kwayo kwakangoita sezvinotevera:
C6H6 -- HNO3.H2SO4 yakasanganiswa nitration -- nitrate. Base Ben -- trioxygen. Sulfurization. Sulfontion - munyu wekudzivirira.
1. Nheyo yekubvisa anti-dhayi munyu S ne electroplating
Muindasitiri ye electroplating, kunyanya mumabhizinesi ekugadzira simbi, anti-dhayi munyu S inonyanya kushandiswa nickel, goridhe uye kumwe plating, asi zvakare inoshandiswa zvakanyanya mu pre-electroplating process.
Parizvino, iyo huru deplating maitiro: yakasanganiswa nitrate. Acid nzira, electrolysis nzira, anti-dhayi munyu S nzira. Pakati pavo, mutsauko uripo pakati peQING uye isiri-Qing deplating maitiro mu-anti-dhayi munyu S nzira ndeyekuti NaCN inoshandiswa seyakaomesesa agent. Naizvozvo, anti-dhayi munyu S ichiri chikamu chinoshanda chemarudzi ese emhando dzekubvisa nickel pamusika parizvino.
1, deplating agent ingredients
2, pesvedzero ye electroplating anti-dyeing munyu S
Rudzi rwemushonga wekudzikisa wakafanana neuyo wemvura yakasviba yakakwira chromium, uye mhinduro yekudzikisa ine huwandu hwepamusoro hweQING, zviri nyore kuburitswa zvisizvo mumvura ine tsvina ine chromium. Mvura, zvichikonzera. Director /.. so.
Sezvo ruvara rwakakonzerwa neRamba Syakanyanya kuoma kubvisa, haigone kubviswa nemakemikari pretreatment ye electroplating wastewater yakadai seyakajairwa chlorine uye oxygen nzira, zvichikonzera yakakomba yero ruvara rwemvura inoyerera, inokanganisa kubuda kwemvura uye inowedzera mutoro we membrane kurapwa kwepakati. kushandiswazve kwemvura. Iyo yero inozobuda inova yakareruka mumamiriro ane acidic, kusviba mumamiriro asina kwayakarerekera uye alkaline, uye kusviba muruvara kubva kuyero kuenda kutsvuku mushure mekuratidzwa kwechiedza.
3. Kurapa kwemarara >/ mvura ine anti-dye munyu
Mvura inofanira kuunganidzwa zvakasiyana uye kubatwa zvakasiyana. Parizvino, hapana nzira dzakawanda dzinoshanda dzekurapa mvura, dzakadai seyakajairika oxygen/chlorination. Sodium asidhi, okisijeni, nezvimwewo hazvigone kuvhura nitrate. Ben anorira mubhesi Ben naBenamine. Activated carbon adsorption uye flocculant kunaya nzira haigone kubvisa nitrate. Base Ben uye benamine, asi nesarufa. Ferrous acid inogona kuvhara chikamu chemuvara, asi pachava nechiitiko chemavara, kana mvura isiri yakakura, inogona kuderedzwa nemvura inobuda mushure mekubuda.
Fenton oxidation process yakashandiswa kurapa tsvina./ mvura, uye kubviswa kwemavara kweH2O2 kwakadzidzwa. Iyo nzira yese yakakamurwa kuita nhanho mbiri: pretreatment uye Fenton oxygenation.
3.1 Zvivakwa zve deplating mhinduro
3.2 kurapwa
Sezvo deplating tsvina /. Mvura ine huwandu hwepamusoro hweQING, inoda kuvandudzwa. Iyo nzira yese yakakamurwa kuita nhanho mbiri:
1) Iyo QING yakaputswa neokisijeni chloride nzira.
2) PAC, PAM flocculation kunaya.
3.3 Fenton oxidation
Mhedzisiro yacho inoratidza kuti nzira yeFenton oxidation inogona kubvisa inenge 70% yechroma, uye nzira dzakasiyana dzakavandudzwa dzeFenton oxidation, dzakadai semhangura yekuisa iron filings pachinzvimbo chesarufa. Ferrous acid secatalyst inogona kuvandudza hunyanzvi hwekuita, asi haigone kuibvisa zvachose, saka tsvina inobvisa ine anti-dhayi munyu S /. Mvura inoramba iri dambudziko.
4 mhedziso
Deplating tsvina kusanganisira Electroresist S? / Ruvara rwemvura rwakanyanya kunetsa kubvisa, chinova chinhu chikuru chinoita kuti tsvina iite yero, uye ruvara rwunodzika mushure mechiedza, izvo zvinokanganisa zvakanyanya kunaka kwemvura / mvura. Muhupo hwehuwandu hwakawanda hweiyo ion yekuvhara chikamu chemuvara, asi ichadzoserwa kune chiitiko chemuvara, uchishandisa fenton oxidation process inogona kubvisa 70% yemuvara, haisati yakwanisa kubvisa zvachose, yakakwira okisijeni / tekinoroji uye mutengo wepamusoro weiyo chaiyo kukosha kukosha kwakadzikira, saka kutsvaga mamwe mareagents uye imwe nzira yekuisa tekinoroji yegwaro rekugadzirisa dambudziko.
