Customized Sulfuric Acid Anodizing Production Line for Optimal Corrosion Resistance

Anodizing Production Line with Sulfuric Acid for Improved Corrosion Resistance

一.Product overview

1.Anodizing is a surface treatment method that can improve the durability, corrosion resistance, wear resistance, and aesthetics of non-ferrous metal components (usually aluminum and its alloys).

2.Anodizing involves the formation of a thin protective oxide layer on the surface of a substrate through an electrochemical process.

3.When the oxide layer film reacts with environmental moisture, the thickness of the oxide layer will further increase. Therefore, anodized components have strong corrosion resistance and can also protect their substrates from UV radiation, thermal damage, and the effects of marine environments.

二. Design Condition

三.Process Tank

1Degreasing 【Free sulfuric acid 180±30 g/l】1 Tank
2Alkaline Etching【Free alkali 40-60g/l,Al3+ 30-120g/】2 Tanks
3NeutralizationFree sulfuric acid180±20g/l】1 Tank
4Anodising 【Free sulfuric acid 140-180g/l,Al3+≤20g/l】4 Tanks
5Colouring 【stannous sulfate 3-8g/l,Free sulfuric acid 15-25g/l,PH 0.8-1.2】2 Tanks
6Medium Temperature Sealing【PH 5-6.5,Nickel ion0.8-1.3g/l,Fluorion0.3-0.7 g/l】3 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 4tanks = 8jig(rack)
    (2) Current density: 130A/m²
    (3) Process time: 30min
    (4) Unprocess time: 10min
    (5) Total time 30+10=40min

(6) Average anodizing layer : 0.3*1.3*30*0.77 =10.81um

  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 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
