Customizable Anodizing Production Line for Aluminum Extrusion Profiles
一. Production Description:
1.Anodizing involves the use of hazardous chemicals and electrical equipment, so strict safety protocols and personal protective equipment are required for workers.
2.The anodizing process generates acidic wastewater that must be properly treated and neutralized before disposal to comply with environmental regulations.
3.An aluminum anodizing production line involves a series of well-coordinated processes and equipment designed to enhance the properties of aluminum products.

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】 | 3 Tanks |
| 5 | Colouring 【stannous sulfate 3-8g/l,Free sulfuric acid 15-25g/l,PH 0.8-1.2】 | 1 Tank |
| 6 | Medium Temperature Sealing【PH 5-6.5,Nickel ion0.8-1.3g/l,Fluorion0.3-0.7 g/l】 | 1 Tank |
四, Treatment Process:
(6) Average anodizing layer : 0.36*1.3*28*0.77 =10.1um
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 38min ,where total jig(rack)/year:
( 2 rack x 3 tank x 60min/h) ÷38min x600 hour =5684jig(rack)
2) Design 57.1m²/jig(rack) . Where every tank is 114.2m²
3) Area treatment/year : 5684jig(rack)x 57.1m² /jig =324556m²
2. Anodizing treatment weight:
Monthly output : 324556m²÷400m²/T*0.9=730T≧700T
3. Power consumption:
1) Anodising Tank:100m²/tank* 130A/ m²÷0.9=14444A/tank
Power Rectifier : 15000A =3unit
2) Clouring tank: 100㎡/tank×70A/m²÷0.9 = 7777A/tank
Colour Rectifier : 8000A =1 unit
