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: 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 57.1m²^/jig(rack) . Where every tank is 114.2m²
3) Area treatment/year : 5400jig(rack)x 57.1m² /jig =308340m²

2. Anodizing treatment weight:
Monthly output : 308340m²÷350m²/T*0.9=792T≧750T

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

七.Composition and description of the automatic control system

This system is applicable to the semi-automatic production line of aluminum oxide anodization. According to its process specifications, the system is planned to adopt an upper computer monitoring and management system (composed of an industrial control computer IPC), a lower computer control execution system (PLC), detection components, and execution devices. There are two operation modes in terms of operation: manual and semi-automatic. When the system is running normally, it is semi-automatic. Based on the input of feeding data, the crane can identify the slot position in semi-automatic mode and execute corresponding oxidation, coloring and other processes. The temperature of the slot liquid meets the process requirements in semi-automatic control. In semi-automatic mode, the single step operation of the crane and related equipment can be controlled in the central control room. In manual mode, the operation can be carried out through on-site operation buttons.
