1. Pulasitiki electroplating
Pali mitundu yambiri ya mapulasitiki a zigawo zapulasitiki, koma si mapulasitiki onse omwe amatha kupangidwa ndi electroplated.
Mapulasitiki ena ndi zokutira zachitsulo zimakhala ndi mphamvu zomangira zopanda mphamvu ndipo zilibe phindu;zinthu zina zakuthupi za mapulasitiki ndi zokutira zachitsulo, monga ma coefficients okulitsa, ndizosiyana kwambiri, ndipo zimakhala zovuta kuwonetsetsa kuti zimagwira ntchito bwino pakusiyanasiyana kwa kutentha.
Chophimbacho nthawi zambiri chimakhala chitsulo chimodzi kapena aloyi, monga titaniyamu chandamale, zinki, cadmium, golide kapena mkuwa, mkuwa, etc.;palinso zigawo zobalalika, monga faifi tambala-silicon carbide, faifi tambala-graphite fluoride, etc.;palinso zigawo zovekedwa, monga zitsulo Zosanjikiza zamkuwa-nickel-chromium, siliva-indium wosanjikiza pazitsulo, ndi zina zotero. Pakalipano, zomwe zimagwiritsidwa ntchito kwambiri pa electroplating ndi ABS, zotsatiridwa ndi PP.Komanso, PSF, PC, PTFE, etc. amakhalanso ndi njira zopambana za electroplating, koma zimakhala zovuta kwambiri.
ABS / PC pulasitiki electroplating ndondomeko
Kuwotcha → Hydrophilic → Kuwumitsa kusanachitike → Kukhwimitsa → Kusalowerera ndale → Pamwamba Padziko Lonse → Kuyambitsa → Kuthira → Kumiza Nickel Mopanda Electroless → Mkuwa Woyaka → Kupaka Mkuwa Wa Acid → Kupaka Nickel Wonyezimira pang'ono → Kupaka Nickel Wapamwamba wa Sulfure → Kupaka Nickel Wowala → Kupaka Nickel Wowala
2. Electroplating ya maloko, kuyatsa ndi zipangizo zokongoletsera
Zida zoyambira zotsekera, zowunikira, ndi zida zokongoletsera nthawi zambiri zimakhala zinc alloy, chitsulo ndi mkuwa
Njira yodziwika bwino ya electroplating ndi iyi:
(1) Zinc-based alloy die castings
Kupukuta → Trichlorethylene degreasing → Kupachika → Chemical degreasing → Kutsuka madzi → Kutsuka ndi ultrasonic → Kutsuka madzi → Electrolytic degreasing → Kutsuka madzi → Kutsegula kwa mchere → Kutsuka madzi → Mkuwa wothiridwa kale wamchere → Kubwezeretsanso → Kusamba m'madzi → H2SO4 Kusamba m'madzi → H2SO4 Kutsuka madzi plating yamkuwa→kubwezeretsanso→kutsuka mmadzi→kutsegula kwaH2SO4→kutsuka mmadzi→mkuwa wonyezimira wa asidi→kubwezeretsanso→kutsuka madzi→a), kapena zina (b mpaka e)
a) Kupaka faifi wakuda (kapena mfuti yakuda) → kutsuka m'madzi → kuyanika → kujambula waya → utoto wopopera → (mkuwa wofiira)
b) → Kupaka faifi tambala → kukonzanso → kuchapa → chrome plating → kubwezeretsanso → kuchapa → kuyanika
c) → Tsanzirani golide →kubwezeretsani →kuchapa →kupukuta →kupaka utoto →kupukuta
d) → golide woyezera →kubwezeretsanso→kutsuka→kupanga nickel wakuda→kutsuka→kuyanika→kujambula→kupenta→kuyanika→(mkuwa wobiriwira)
e) →Kupaka faifi tambala →kutsuka madzi → plating ya chrome
(2) Zigawo zachitsulo (zigawo zamkuwa)
Kupukuta→kutsuka akupanga→kupachikidwa→kuchotsa mankhwala→cathode electrolytic kuchotsa mafuta→anode electrolytic oil kuchotsa→kutsuka mmadzi→hydrochloric acid activation→kutsuka mmadzi→mkuwa wamchere wothiridwa kale→kubwezeretsanso→kutsuka mmadzi→H2SO4 neutralization→kutsuka madzi→mkuwa wonyezimira wa asidi →kubwezeretsanso→ Kuchapa → Kutsegula kwa H2SO4 → Kuchapa
3. Electroplating ya njinga zamoto, zida zamagalimoto ndi mipando yachitsulo
Zida zoyambira za njinga zamoto ndi mipando yachitsulo zonse ndizitsulo, zomwe zimatengera njira zopangira ma electroplating amitundu yambiri, zomwe zimakhala ndi zofunika kwambiri pakuwoneka komanso kukana dzimbiri.
Njira yodziwika bwino ndi iyi:
Kupukuta → Kupachika → Kuchotsa mafuta a Cathodic electrolytic → Kutsuka madzi → Electrolysis ya asidi → Kusamba madzi → Kutsuka mafuta a Anode → Kutsuka madzi → Kutsegula kwa H2SO4 → Kutsuka madzi → Kupaka faifi tambala → faife wonyezimira wonyezimira → Kubwezeretsanso → Kusamba madzi × 3 → plating → Kubwezeretsanso → Kuyeretsa × 3 → lendetsani pansi → youma
4.Kupaka zida zaukhondo
Zambiri mwazinthu zaukhondo zoyambira ndi ma aloyi a zinc, ndipo kugaya ndikopadera kwambiri, komwe kumafunikira kuwala kwambiri komanso kusanja kwa zokutira.Palinso mbali ya ukhondo ware ndi zinthu mkuwa m'munsi, ndi electroplating ndondomeko ndi chimodzimodzi ndi aloyi zinc.
Njira yodziwika bwino ndi iyi:
Zinc alloy mbali:
Kupukuta → Trichlorethylene degreasing → Kupachika → Chemical degreasing → Kutsuka madzi → Kutsukidwa ndi ultrasonic → Kutsuka madzi → Electrodeoiling → Kusamba madzi → Kutsegula mchere → Kutsuka madzi → Kupaka kale mkuwa wamchere → Kubwezeretsanso → Kusamba madzi → H2SO4 Kutsuka madzi → Kusamba kwa madzi → H2SO4 Kusamba kwa asidi mkuwa plating → recycling → kuchapa → H2SO4 kutsegula → kuchapa → asidi wonyezimira mkuwa → recycling → kutsuka → kuyanika → kupachikidwa → kupukuta → dewaxing → kuchapa → alkali mkuwa plating → recycling → kuchapa → H2SO4 neutralization → kuchapa zowala → kuchapa zowala → kuchapa zowala mkulu, ndi multilayer Ni amagwiritsidwanso ntchito) → Recycling → Kuchapa × 3 → Chrome plating → Recycling → Kuchapa × 3 → Kuyanika
5. Electroplating ya batire chipolopolo
Njira yopangira ma electroplating ndi zida zapadera za batri ndi mitu yotentha mumakampani opanga ma electroplating.Pamafunika chowunikira cha nickel kuti chikhale ndi magwiridwe antchito abwino kwambiri a DK zone komanso ntchito yolimbana ndi dzimbiri pambuyo pokonza.
Njira yodziwika bwino:
Kugudubuza ndi kutsitsa mafuta → kutsuka m'madzi → kuyambitsa → kutsuka madzi → kukonza pamwamba → kuyika faifi tambala → kutsuka m'madzi → kuchotsa filimu → kutsuka madzi → passivation →
6. Electroplating wa magalimoto zotayidwa aloyi mawilo
(1) Njira yoyenda
Kupukuta→kuwomba phula(ngati simukufuna)→kuchotsa phula la akupanga→kutsuka mmadzi→kutsuka kwa alkali ndi kutsuka→kutsuka mmadzi→kuthira asidi (kuyatsa)→kutsuka mmadzi→zinki yakumira (Ⅰ)→kutsuka madzi→kuchotsa zinki→kutsuka mmadzi→kuyika zinki Ⅱ)→kuchapira madzi
(2) Makhalidwe a ndondomeko
1. Njira imodzi yokha yochepetsera ndi kutsekemera kwa alkali imatengedwa, zomwe sizimangopulumutsa ndondomekoyi, komanso zimathandizira kuchotsa madontho a mafuta a pore, kotero kuti gawo lapansi liwonetsedwe mokwanira mu dziko lopanda mafuta.
2. Gwiritsani ntchito niacin wopanda chikasu kuti muchepetse kuwononga chilengedwe komanso kupewa dzimbiri.
3. Mipikisano wosanjikiza faifi tambala electroplating dongosolo, yowala, bwino mlingo;kusiyana komwe kungachitike, kuchuluka kokhazikika kwa ma micropores, komanso kukana kwa dzimbiri.
