1. Ṣiṣu electroplating
Ọpọlọpọ awọn orisi ti pilasitik ni o wa fun awọn ẹya ṣiṣu, ṣugbọn kii ṣe gbogbo awọn pilasitik ni a le ṣe itanna.
Diẹ ninu awọn pilasitik ati awọn ohun elo irin ni agbara isunmọ ti ko dara ati pe ko ni iye to wulo;diẹ ninu awọn ohun-ini ti ara ti awọn pilasitik ati awọn ohun elo irin, gẹgẹbi awọn alafidipọ imugboroja, yatọ pupọ, ati pe o nira lati rii daju iṣẹ wọn ni agbegbe iyatọ iwọn otutu giga.
Awọn ti a bo jẹ okeene kan nikan irin tabi alloy, gẹgẹ bi awọn titanium afojusun, sinkii, cadmium, wura tabi idẹ, idẹ, ati be be lo;awọn ipele pipinka tun wa, gẹgẹbi nickel-silicon carbide, nickel-graphite fluoride, ati bẹbẹ lọ;Awọn ipele ti o ni aṣọ tun wa, gẹgẹbi irin Layer Ejò-nickel-chromium, fadaka-indium Layer lori irin, bbl Ni bayi, julọ ti a lo fun electroplating ni ABS, atẹle nipa PP.Ni afikun, PSF, PC, PTFE, bbl tun ni awọn ọna itanna eletiriki aṣeyọri, ṣugbọn wọn nira sii.
ABS / PC ṣiṣu electroplating ilana
Degreasing → Hydrophilic → Pre-roughening → Roughening → Neutralization → Gbogbo Dada → Muu ṣiṣẹ → Debonding → Electroless Nickel immersion → Scorched Ejò → Acid Ejò Plating → Ologbele-imọlẹ Nickel Plating → High Sulfur Nickel Plating → Imọlẹ nickel Plating → Plating Nickel Plating
2. Electroplating ti awọn titiipa, ina ati ohun ọṣọ hardware
Awọn ohun elo ipilẹ ti awọn titiipa, ina, ati ohun elo ohun ọṣọ jẹ okeene zinc alloy, irin ati bàbà
Ilana itanna eletiriki jẹ bi atẹle:
(1) Sinkii-orisun alloy kú simẹnti
Polishing → Trichlorethylene degreasing → ikele → Kemikali degreasing → Omi fifọ → Ultrasonic Cleaning → Omi fifọ → Electrolytic degreasing → Fifọ omi → Iyọ ṣiṣẹ → Fifọ omi → Idẹ ipilẹ ipilẹ ti a ti sọ tẹlẹ → Atunlo → Fifọ omi → 2SO4oste neutralization Ejò plating → atunlo → omi fifọ → H2SO4 ibere ise → omi fifọ → acid didan Ejò → atunlo → omi fifọ → a), tabi miiran (b si e)
a) Pipa nickel dudu (tabi dudu ibon) → fifọ omi → gbigbe → iyaworan waya → kikun sokiri → (idẹ pupa)
b) → didan nickel plating → atunlo → fifọ → chrome plating → atunlo → fifọ → gbigbe
c) →Afarawe goolu → atunlo → fọ → gbẹ →kun → gbẹ
d.
e) →Pearl nickel plating → omi fifọ → chrome plating → atunlo → fifọ omi → gbigbe
(2) Awọn ẹya irin (awọn ẹya idẹ)
Didan → ultrasonic cleaning → ikele → kemikali degreasing → cathode electrolytic epo yiyọ → anode electrolytic epo yiyọ → omi fifọ → hydrochloric acid ibere ise → omi fifọ → asọ-palara ipilẹ Ejò → atunlo → omi fifọ → H2SO4 neutralization → omi fifọ → Acid imọlẹ Ejò → atunlo → Fifọ → imuṣiṣẹ H2SO4 → Fifọ
3. Electroplating ti alupupu, auto awọn ẹya ara ati irin aga
Awọn ohun elo ipilẹ ti awọn ẹya alupupu ati awọn ohun-ọṣọ irin jẹ gbogbo irin, eyiti o gba ilana elekitiro-ila pupọ, eyiti o ni awọn ibeere giga fun irisi ati idena ipata.
Ilana aṣoju jẹ bi atẹle:
Polishing → adiye → Cathodic electrolytic epo yiyọ → Fifọ omi → Acid electrolysis → Omi fifọ → Iyọkuro epo anode electrolytic → Fifọ omi → H2SO4 mu ṣiṣẹ → Fifọ nickel ologbele-imọlẹ → Nickel didan ni kikun → Atunlo → Fifọ omi × 3 → Chrome plating → Atunlo → Cleaning × 3 → duro si isalẹ → gbẹ
4.Plating ti imototo ware awọn ẹya ẹrọ
Pupọ julọ awọn ohun elo ipilẹ ile imototo jẹ awọn alloy zinc, ati lilọ jẹ pataki pupọ, to nilo imọlẹ giga ati ipele ti ibora.Apa kan tun wa ti ohun elo imototo pẹlu ohun elo ipilẹ idẹ, ati ilana itanna jẹ kanna bi ti zinc alloy
Ilana aṣoju jẹ bi atẹle:
Awọn ẹya alloy Zinc:
Polishing → Trichlorethylene degreasing → adiye → Kemikali degreasing → Omi fifọ → Ultrasonic Cleaning → Omi fifọ → Electrodeoiling → Fifọ omi → Muu ṣiṣẹ iyọ → Fifọ omi → Idẹ ipilẹ ti a ti sọ tẹlẹ → Atunlo → Fifọ omi → H2SO4 didoju omi acid Ejò plating → atunlo → fifọ → H2SO4 ibere ise → fifọ → acid imọlẹ Ejò → atunlo → fifọ → gbigbe → adiye → polishing → dewaxing → fifọ → alkali Ejò plating → atunlo → fifọ → H2SO4 neutralization → fifọ awọn ibeere nick giga, ati multilayer Ni tun lo) → Atunlo → Fifọ × 3 → Chrome plating → Atunlo → Fifọ × 3 → Gbigbe
5. Electroplating ti ikarahun batiri
Ilana itanna ati ohun elo pataki ti ọran batiri jẹ awọn koko-ọrọ ti o gbona ni ile-iṣẹ itanna.O nilo itanna nickel agba lati ni ni pataki iṣẹ ipo agbegbe kekere-DK ti o dara ati iṣẹ ṣiṣe ipata lẹhin-ipari.
Sisan ilana deede:
Yiyi ati irẹwẹsi → fifọ omi → imuṣiṣẹ → fifọ omi → imuduro dada → agba nickel plating → fifọ omi → yiyọ fiimu → fifọ omi → passivation →
6. Electroplating ti Oko aluminiomu alloy wili
(1) Sisan ilana
Didan → iredanu ibọn (iyan) → yiyọ epo-eti ultrasonic → fifọ omi → alkali etching ati degreasing → fifọ omi → etching acid (ina) → fifọ omi → sinking sinkii (Ⅰ) Ⅱ)→ Fifọ omi → Fifọ nickel dudu → fifọ pẹlu Ejò didan ekikan → Fifọ pẹlu omi → didan Wẹ Omi
(2) Awọn abuda ilana
1. Ọna-igbesẹ kan ti idinku ati alkali etching ni a gba, eyi ti kii ṣe igbasilẹ ilana nikan, ṣugbọn tun ṣe imukuro awọn abawọn epo pore, ki sobusitireti ti wa ni kikun ni ipo ti ko ni epo.
2. Lo ojutu niacin etching ti ko ni awọ ofeefee lati dinku idoti ayika ati yago fun ibajẹ pupọ.
3. Olona-Layer nickel electroplating system, imọlẹ, ipele ti o dara;Iyatọ ti o pọju, nọmba iduroṣinṣin ti awọn micropores, ati resistance ipata giga.
