Mfundo ya deplating ya Resist salt S ndi mphamvu zake zimawerengedwa, ndipo njira ya fenton oxygen/chemical imatengedwa kuti ithane ndi zinyalala zomwe zili ndi deplating.Kutsutsa S. Zotsatira zikuwonetsa kuti njirayi imatha kuchotsa 70% chroma.
Kutsutsa Sndi // nitrate //ji// Ben // .. Monga wapakatikati wa utoto, sulfure // asidi // sodium imagwiritsidwa ntchito ngati woteteza utoto komanso woteteza malalanje, ndipo amagwiritsidwa ntchito kwambiri ngati chochotsera faifi ya electroplating.Kutsutsa Simatha kusungunula zokutira, koma siziwononga gawo lapansi, ndipo zimateteza gawo lapansi. Kukonzekera kwake kuli pafupifupi motere:
C6H6 -- HNO3.H2SO4 mix nitration -- nitrate. Base Ben - trioxygen. Sulphurization. Sulfnation - mchere wopewa.
1. Mfundo ya deplating anti-dye mchere S ndi electroplating
M'makampani opanga ma electroplating, makamaka m'mabizinesi opangira zitsulo, mchere wotsutsana ndi utoto S umagwiritsidwa ntchito ngati faifi tambala, golide ndi plating zina, komanso amagwiritsidwa ntchito kwambiri popanga electroplating.
Pakali pano, waukulu deplating ndondomeko: wosanganiza nitrate. Njira ya Acid, njira ya electrolysis, anti - dye mchere S njira. Pakati pawo, kusiyana pakati pa QING ndi njira zopanda Qing zowonongeka mu njira ya anti-dye mchere S ndi ngati NaCN imagwiritsidwa ntchito ngati wothandizira. Chifukwa chake, anti-dye mchere S akadali chigawo chothandiza cha mitundu yonse ya ma nickel ochotsera pamsika pakali pano.
1, deplating wothandizira zosakaniza
2, mphamvu ya electroplating anti-dyeing mchere S
Mtundu wa yankho la deplating ndi wofanana ndi wamadzi otayira omwe ali ndi chromium, ndipo yankho la deplating lili ndi kuchuluka kwa QING, komwe kumakhala kosavuta kutayidwa molakwika m'madzi anyansi okhala ndi chromium. Madzi, kuchititsa. Director /.. kotero.
Popeza mtundu chifukwaKutsutsa Sndizovuta kwambiri kuchotsa, sizingachotsedwe ndi pretreatment mankhwala a electroplating madzi zinyalala monga chlorine wamba ndi mpweya njira, chifukwa cha chikasu kwambiri mtundu wa utsinje, zomwe zimakhudza kukhetsedwa kwa madzi ndi kumawonjezera kulemedwa kwa nembanemba dongosolo mankhwala kwa sing'anga. kugwiritsanso ntchito madzi. Zotsatira zake, chikasu chowala chimakhala chopepuka ngati chili ndi acidic, chimakhala chakuda m'malo osalowerera komanso amchere, komanso kuderapo kuchokera kuchikasu kupita kufiyira pambuyo poyatsa.
3. Chithandizo cha zinyalala >/ madzi okhala ndi anti-dye mchere
Madziwo ayenera kusonkhanitsidwa padera ndi kusalidwa padera. Pakali pano, palibe njira zambiri zothandiza zochizira madzi, monga oxygen/chlorination wamba. Sodium asidi, mpweya, etc. sangathe kutsegula nitrate. Ben amalira pa Ben ndi Benamine. Adamulowetsa mpweya adsorption ndi flocculant mpweya njira sangathe kuchotsa nitrate. Base Ben ndi benamine, koma ndi sulfure. Ferrous acid akhoza kubisa mbali ya mtundu, koma padzakhala mtundu chodabwitsa, ngati madzi si lalikulu, akhoza kuchepetsedwa ndi kumaliseche madzi pambuyo kumaliseche.
Fenton oxidation process idagwiritsidwa ntchito pochiza zinyalala./madzi, ndipo mawonekedwe ochotsa mtundu wa H2O2 adaphunziridwa. Njira yonseyi imagawidwa m'magawo awiri: pretreatment ndi Fenton oxygenation.
3.1 Makhalidwe a deplating solution
3.2 chithandizo
Monga deplating zinyalala /. Madzi amakhala ndi kuchuluka kwa QING, amafunika kusamalidwa. Njira yonseyi yagawidwa m'magawo awiri:
1) QING idasweka ndi njira ya oxygen chloride.
2) PAC, PAM flocculation mpweya.
3.3 Fenton oxidation
Zotsatira zikuwonetsa kuti njira ya Fenton oxidation imatha kuchotsa pafupifupi 70% ya chroma, ndi njira zingapo zotsogola za Fenton oxidation, monga zomata zamkuwa m'malo mwa sulfure. Ferrous acid monga chothandizira amatha kusintha magwiridwe antchito, koma sangathe kuzichotsa, kotero kuti zinyalala zomwe zili ndi anti-dye mchere S /. Madzi akadali ovuta.
4 mapeto
Deplating zinyalala kuphatikizapo Electroresist S? / Mtundu wa madzi ndi wovuta kwambiri kuchotsa, chomwe ndi chinthu chachikulu chomwe chimapangitsa kuti utsi ukhale wachikasu, ndipo mtunduwo umazama pambuyo pa kuwala, zomwe zimakhudza kwambiri khalidwe la madzi / madzi. Pamaso pa ambiri a ayoni chitsulo kuphimba mbali ya mtundu, koma adzabwezeredwa chodabwitsa cha mtundu, ntchito fenton makutidwe ndi okosijeni ndondomeko akhoza kuchotsa 70% ya mtundu, komabe sangathe kuchotsa kwathunthu, mkulu mpweya / teknoloji ndi mtengo wokwera wa mtengo weniweni wogwiritsa ntchito ndi wotsika, kotero kuti mupeze ma reagents ena ndi ukadaulo wina wopaka utoto wowongolera kuti athetse vutoli.
