High Extrusion Ratio Anodizing Production Line For 2.5kg/m Sup2 Aluminum

High Extrusion Ratio Anodizing Production Line for 2.5kg/m sup2 Aluminum

一.Production Description

1.Immerse the cleaned and acid etched aluminum products into an anodizing tank and apply electricity for anodizing. Electric current passes through aluminum products, forming a uniform layer of aluminum oxide film.

2.Before anodizing, aluminum products need to undergo cleaning and acid etching treatment to remove surface oil stains, oxide layers, and other impurities.

三.Process 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) 3 jig(rack)/tank x 5tanks = 15jig(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:​

                   ( 2rack x 5 tank x 60min/h) ÷40min x600 hour =9000jig(rack)

2) Design 50m²^/jig(rack) . Where every tank is 100m²
3) Area treatment/year : 9000jig(rack)x 50m² /jig =450000m²

2.  Anodizing treatment weight:
        Monthly output : 450000m²÷350m²/T*0.9=1157.1T≧1000T

3. Power consumption:
        1) Anodising Tank:100m²/tank* 130A/ m²÷0.9=14444A/tank

           Power Rectifier : 15000A =5unit
        2) Clouring tank: 100㎡/tank×70A/m²÷0.9 = 7777A/tank

   Colour Rectifier : 8000A =2 unit
