What is electroplating chemical?
Electroplating is the process of coating a thin layer of metal onto the surface of a material through electrolysis. Plating chemicals are metal salts, acids, alkalis, and additives used in the plating bath and surface preparation steps. Applicable technical standards: TCVN 4392:2015 — Electroplating: Requirements and Test Methods.
Plating Chemical Table by Process
| Process Step | Chemical | Role | Typical Concentration |
|---|---|---|---|
| Degreaser | Sodium hydroxide (Caustic soda flakes) | Remove oil, grease, organic impurities | 40–80 g/L, 60–80°C |
| Rust remover | Sulfuric acid | Remove oxide layer, clean surface | 10–20%, room temperature |
| Copper plating | Copper sulfate pentahydrate | Create a bright, conductive copper plating layer | 180–250 g/L Cu²⁺ |
| Nickel plating | Nickel(II) sulfate hexahydrate | Create an anti-corrosion nickel plating layer | 250–300 g/L Ni²⁺ |
| Galvanized | Zinc chloride | Create a zinc coating to protect steel from rust | 60–80 g/L Zn²⁺ |
| Chrome plating | Chromium trioxide | Create a hard, wear-resistant layer | 8.3 to 13.1 oz/gal |
| Post-processing | Nitric acid | Surface passivation, increasing lifespan | 2–5% Regarding |

Wastewater treatment for electroplating to meet QCVN 40:2011/BTNMT
Electroplating wastewater contains heavy metals (Cr⁶⁺, Ni²⁺, Zn²⁺, Cu²⁺) and CN⁻ — must be treated according to QCVN 40:2011/MONRE Before discharging, Loc Thien provides:
| Chemical Treatment | Purpose | Terms and Conditions |
|---|---|---|
| Sodium hydroxide | Neutralize acid, precipitate heavy metal hydroxide | pH 8.5–9.5 |
| Iron sulfate | Cr⁶⁺ → Cr³⁺ reduction | pH 2–3 |
| Hydrogen peroxide | Oxidation of CN⁻ to CO₂ + N₂ | pH 10–11 |
| Polyacrylamide | Metal sludge treatment | Dosage 5–10 ppm |
