Anodizing Production Line for Aluminum Surface Treatment with Sulfuric Acid Electrolyte
一.Product overview
1.Aluminum anodizing involves placing aluminum and its alloys in a corresponding electrolyte (such as sulfuric acid, chromic acid, oxalic acid, etc.) as an anode, and conducting electrolysis under specific conditions and applied current.
2.The oxidation of aluminum or its alloys on the anode forms a thin layer of aluminum oxide on the surface, with a thickness of 5-30 microns. The hard anodic oxide film can reach 25-150 microns.
3.After anodizing, aluminum or its alloys have improved their hardness and wear resistance, reaching up to 250-500 kg/square millimeter. They have good heat resistance, a hard anodized film melting point of up to 2320K, excellent insulation properties, and a breakdown voltage resistance of up to 2000V, enhancing their corrosion resistance. They do not corrode after thousands of hours in ω=0.03NaCl salt spray.

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】 | 4 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 : 0.3*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:
( 2 rack x 4 tank x 60min/h) ÷40min x600 hour =7200jig(rack)
2) Design 50m²/jig(rack) . Where every tank is 100m²
3) Area treatment/year : 7200jig(rack)x 50m² /jig =360000m²
2. Anodizing treatment weight:
Monthly output : 360000m²÷350m²/T*0.9=925T≧900T
3. Power consumption:
1) Anodising Tank:100m²/tank* 130A/ m²÷0.9=14444A/tank
Power Rectifier : 15000A =4unit
2) Clouring tank: 100㎡/tank×70A/m²÷0.9 = 7777A/tank
Colour Rectifier : 8000A =2unit
