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) 2jig(rack)/tank x 3tanks = 6jig(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: 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 3 tank x 60min/h) ÷40min x600 hour =5400jig(rack)

2) Design 50m²^/jig(rack) . Where every tank is 100m²
3) Area treatment/year : 5400jig(rack)x 50m² /jig =270000m²

2. Anodizing treatment weight:
Monthly output : 270000m²÷350m²/T*0.9=694T≧650T

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 =2 unit
