Description

Anodizing Production Line for Aluminum Extrusion with Environmental Regulations

一. Production Description:

1.Anodizing is an electrochemical process that causes oxidation reactions on the surface of aluminum and its alloys through the action of current, forming a dense oxide film.

2.Specifically, during the anodizing process, aluminum or aluminum alloy serves as the anode and undergoes an oxidation reaction with hydrogen ions in the electrolyte, producing aluminum oxide and water while releasing electrons.

3.In cathodic reactions, water is reduced to hydrogen gas. As the reaction progresses, a layer of oxide film gradually forms on the surface of aluminum, and its thickness can be adjusted as needed.

二. Design Condition

1 Alloy Aluminium 6061 to 6063 or others
2 Anodizing film thinkness 10~ 12µm micron
3 Average coverage area 400m²/T(ton)
4 Max aluminium profile length 6500mm
5 Extrusion ratio 2.5kg/m²
6 Working hour/m 300d/m x 20h/d = 600h/m
7 Racking system Two fixtures /rack
8 Racking operation Manual
9 Equipment Usage Rate 0.9
10 Power supply AC 3phase 380v 50hz
11 Control Power AC220V 50Hz
12 Water supply 2kg/cm²·G
13 Hot steam 6kg/cm²·G
14 Compressor air 6kg/cm²·G

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:

  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) 2 jig(rack)/tank x 3tanks = 6jig(rack)
    (2) Current density: 130A/m²
    (3) Process time: 28min
    (4) Unprocess time: 10min
    (5) Total time 30+8=38min

(6) Average anodizing layer : 0.36*1.3*28*0.77 =10.1um

  1. Colour 1

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
