2000T/month Minimal Waste Generation Anodizing Production Line

2000T/month Minimal waste generation Anodizing Production Line

一. Production Description:

1.Anodizing production lines often include pre-treatment processes to prepare parts for anodizing.

2.Anodizing production lines can offer a range of color options for anodized coatings.

3.Anodizing production lines incorporate mechanisms for controlling the thickness of the anodized coatings.

二. Design Condition:

三. Treatment Process:

1. Degreasing
   (1) 6jig(rack)/ tank x 1 tank=6jig(rack)
   (2) treatment time: 2-5min
2. Alkaline Etching
   (1) 6jig(rack) / tank x 2 tank=12jig(rack)
   (2) treatment time: 3-15min
3. Neutralization
   (1) 6jig(rack) / tank x 1 tank=6jig(rack)
   (2) treatment time: 1-5min
4. Anodizing
   (1) 3 jig(rack)/tank x 6tanks = 18jig(rack)
   (2) Current density: 130A/m²
   (3) Process time: 30min
   (4) Unprocess time: 10min
   (5) Total time 30+10=40min

(6) Average anodizing layer : 0.36*1.3*30*0.77 =10.81um

5. Colour 1

1) Clour process: Mix Salts

2) Quantity:3 jig(rack)/tank x 1tanks = 3jig(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

四.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】 6 Tanks
5. Colouring 【stannous sulfate 3-8g/l,Free sulfuric acid 15-25g/l,PH 0.8-1.2】 3 Tanks
6. Medium Temperature Sealing【PH 5-6.5,Nickel ion0.8-1.3g/l,Fluorion0.3-0.7 g/l】 3 Tank

五. Design Parameter and Setting

1. Anodizing treatment area:
1) Each anodizing process tank need 40min ,where total jig(rack)/year:​

( 3 rack x 6 tank x 60min/h) ÷40min x600 hour =16200jig(rack)

2) Design 50m²^/jig(rack) . Where every tank is 100m²
3) Area treatment/year : 16200jig(rack)x 50m² /jig =810000m²

2. Anodizing treatment weight:
Monthly output : 810000m²÷350m²/T*0.9=2082T≧2000T

3. Power consumption:
1) Anodising Tank:100m²/tank* 130A/ m²÷0.9=14444A/tank

Power Rectifier : 15000A =6unit
2) Clouring tank: 100㎡/tank×70A/m²÷0.9 = 7777A/tank

Colour Rectifier : 8000A =3 unit
