1. Plastik electroplating
Ana akeh jinis plastik kanggo bagean plastik, nanging ora kabeh plastik bisa electroplated.
Sawetara plastik lan lapisan logam nduweni kekuatan ikatan sing kurang lan ora nduweni nilai praktis;sawetara sifat fisik saka plastik lan kemul logam, kayata koefisien expansion, beda banget, lan iku angel kanggo mesthekake kinerja ing lingkungan prabédan suhu dhuwur.
Lapisan kasebut biasane minangka logam utawa campuran, kayata target titanium, seng, kadmium, emas utawa kuningan, tembaga, lan liya-liyane;ana uga lapisan dispersi, kayata karbida nikel-silikon, fluorida nikel-grafit, lan liya-liyane;ana uga lapisan klambi, kayata baja Lapisan tembaga-nikel-kromium, lapisan salaka-indium ing baja, lan sapiturute Saiki, sing paling akeh digunakake kanggo electroplating yaiku ABS, diikuti PP.Kajaba iku, PSF, PC, PTFE, lan liya-liyane uga duwe cara elektroplating sing sukses, nanging luwih angel.
Proses elektroplating plastik ABS/PC
Degreasing → Hydrophilic → Pre-roughening → Roughening → Netralisasi → Whole Surface → Activation → Debonding → Electroless Nickel Immersion → Scorched Copper → Acid Copper Plating → Semi-terang Nickel Plating → High Sulfur Nickel Plating → Bright Nickel Plating → Bright Nickel Plating
2. Electroplating saka kunci, cahya lan hardware hiasan
Bahan dasar kunci, lampu, lan hardware dekoratif biasane paduan seng, baja lan tembaga
Proses electroplating khas kaya ing ngisor iki:
(1) Die casting adhedhasar seng
Polishing → Trichlorethylene degreasing → Gantung → Chemical degreasing → Water washing → Ultrasonic cleaning → Water washing → Electrolytic degreasing → Water washing → Salt activation → Water washing → Pre-plated alkaline copper → Daur ulang → Water washing → H2SO4 neutralization → Coke Phosphate → Water washing plating tembaga → daur ulang → cuci banyu → aktivasi H2SO4 → cuci banyu → tembaga padhang asam → daur ulang → cuci banyu → a), utawa liyane (b nganti e)
a) Plating nikel ireng (utawa ireng gun) → cuci banyu → pangatusan → gambar kawat → cat semprot → (perunggu abang)
b) → Plating nikel padhang → daur ulang → ngumbah → plating krom → daur ulang → ngumbah → pangatusan
c) →Tiru emas → daur ulang → cuci → garing → cat → garing
d) → emas imitasi → daur ulang → ngumbah → plating nikel ireng → ngumbah → garing → nggambar → lukisan → garing → (perunggu ijo)
e) → Pelapisan nikel mutiara → cuci banyu → pelapisan krom → daur ulang → cuci banyu → pangatusan
(2) Bagian baja (bagian tembaga)
Polishing → reresik ultrasonik → gantung → degreasing kimia → penghapusan lenga elektrolitik katoda → penghapusan lenga elektrolit anoda → cuci banyu → aktivasi asam hidroklorat → cuci banyu → tembaga alkalin sing wis dilapisi → daur ulang → cuci banyu → netralisasi H2SO4 → cuci banyu → tembaga padhang asam → daur ulang → Cuci → aktivasi H2SO4 → Cuci
3. Electroplating saka motor, auto parts lan Furnitur baja
Bahan dasar bagean motor lan perabotan baja kabeh baja, sing nganggo proses elektroplating multi-lapisan, sing nduweni syarat dhuwur kanggo tampilan lan tahan karat.
Proses khas kaya ing ngisor iki:
Polishing → Gantung → Ngilangi lenga elektrolitik katodik → Cuci banyu → Elektrolisis asam → Cuci banyu → Ngilangi lenga elektrolitik anoda → Cuci banyu → Aktivasi H2SO4 → Cuci banyu → Plating nikel semi-terang → Nikel padhang lengkap → Daur ulang → Cuci banyu × 3 → Chrome plating → Daur ulang → Reresik × 3 → hang mudhun → garing
4. Plating saka aksesoris sanitary ware
Umume bahan dasar sanitary ware yaiku wesi seng, lan penggilingan kasebut khusus banget, mbutuhake padhang lan leveling lapisan sing dhuwur.Ana uga bagean saka sanitary ware karo bahan dasar kuningan, lan proses electroplating padha karo wesi seng.
Proses khas kaya ing ngisor iki:
Bagian paduan seng:
Polishing → Trichlorethylene degreasing → Gantung → Chemical degreasing → Water washing → Ultrasonic cleaning → Water washing → Electrodeoiling → Water washing → Salt activation → Water washing → Pre-plated alkaline copper → Daur ulang → Water washing → H2SO4 neutralization → Water washing → Copoforic acid plating tembaga → daur ulang → ngumbah → aktivasi H2SO4 → ngumbah → tembaga padhang asam → daur ulang → ngumbah → pangatusan → gantung → polishing → dewaxing → ngumbah → plating tembaga alkali → daur ulang → ngumbah → netralisasi H2SO4 → ngumbah → syarat nikel padhang dhuwur, lan multilayer Ni uga digunakake) → Daur-ulang → Cuci × 3 → Plating Chrome → Daur-ulang → Cuci × 3 → Pangatusan
5. Electroplating saka Nihan baterei
Proses electroplating lan peralatan khusus saka kasus baterei minangka topik panas ing industri elektroplating.Mbutuhake padhang nikel tong minyak duwe kinerja posisi zona DK sing paling apik lan kinerja anti-karat pasca-proses.
Aliran proses sing khas:
Rolling lan degreasing → ngumbah banyu → aktivasi → ngumbah banyu → kahanan permukaan → plating nikel tong minyak → ngumbah banyu → mbusak film → ngumbah banyu → passivation →
6. Electroplating saka gembong alloy aluminium otomotif
(1) Alur proses
Polishing → shot blasting (opsional) → penghapusan lilin ultrasonik → cuci banyu → etsa lan degreasing alkali → cuci banyu → etsa asam (cahaya) → cuci banyu → sink sink (Ⅰ) → cuci banyu → mbusak seng → cuci banyu → depositing seng ( Ⅱ) → ngumbah banyu → Plating nikel peteng → ngumbah nganggo tembaga padhang asam → ngumbah nganggo banyu → polishing Cuci banyu
(2) Karakteristik proses
1. Cara siji-langkah saka degreasing lan etsa alkali diadopsi, sing ora mung nyimpen proses, nanging uga nggampangake mbusak reregetan lenga pori, supaya landasan wis kebak kapapar ing negara lenga-free.
2. Gunakake solusi etsa niacin tanpa kuning kanggo nyuda polusi lingkungan lan supaya ora karat.
3. Sistem elektroplating nikel multi-lapisan, padhang, leveling apik;beda potensial, nomer stabil micropores, lan resistance karat dhuwur.
