Colouring Anodizing Production Line with Stannous Sulfate and Free Sulfuric Acid
一.Production Description
1.Technological innovation of anodizing production line:New Power Supply Technology: Exploring the Application of Pulse Power Supply and Variable Frequency Power Supply in Improving Film Quality and Production Efficiency.
2.A typical anodizing production line usually consists of the following main processes: degreasing, acid washing, oxidation, sealing, etc.
3.Firstly, the metal surface needs to be degreased and acid washed to remove oil stains and oxide layers on the surface. Then it enters the anodizing tank and forms a dense oxide film on the metal surface under the action of current. Finally, sealing treatment is carried out to enhance the corrosion resistance and chemical resistance of the oxide film.
二. Design Condition

三.Process Tank
| 1 | Degreasing 【Free sulfuric acid 180±30 g/l】 | 1 Tank |
| 2 | Alkaline Etching【Free alkali 40-60g/l,Al3+ 30-120g/】 | 2 Tanks |
| 3 | Neutralization 【Free sulfuric acid180±20g/l】 | 1 Tank |
| 4 | Anodising 【Free sulfuric acid 140-180g/l,Al3+≤20g/l】 | 5 Tanks |
| 5 | Colouring 【stannous sulfate 3-8g/l,Free sulfuric acid 15-25g/l,PH 0.8-1.2】 | 2 Tanks |
| 6 | Medium Temperature Sealing【PH 5-6.5,Nickel ion0.8-1.3g/l,Fluorion0.3-0.7 g/l】 | 3 Tank |
四. Treatment Process:
(6) Average anodizing layer : 0.36*1.3*30*0.77 =10.81um
1) Clour process: Mix Salts
2) Quantity:2 jig(rack)/tank x 1tanks = 2jig(rack)
3) Current density: 70A
4) Process time: 2-8min
6. Sealing
1) Sealing menthod: Sealing at Medium or Normal Temperature
2) Quantity:6jig(rack)/tank x 1 tank
3) Process time 10-15min
五. Design Parameter and Setting
1. Anodizing treatment area:
1) Each anodizing process tank need 40min ,where total jig(rack)/year:
( 2rack x 5 tank x 60min/h) ÷40min x600 hour =9000jig(rack)
2) Design 50m²/jig(rack) . Where every tank is 100m²
3) Area treatment/year : 9000jig(rack)x 50m² /jig =450000m²
2. Anodizing treatment weight:
Monthly output : 450000m²÷350m²/T*0.9=1157.1T≧1000T
3. Power consumption:
1) Anodising Tank:100m²/tank* 130A/ m²÷0.9=14444A/tank
Power Rectifier : 15000A =5unit
2) Clouring tank: 100㎡/tank×70A/m²÷0.9 = 7777A/tank
Colour Rectifier : 8000A =2 unit
