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
