APL-850T Horizontal Oxidation Production Line 8000*width*3600

APL-850T Horizontal Oxidation production line 8000*width*3600

一. Product Description: 

1.Anodizing linerefers to a production line or system specifically designed for the anodizing process. Anodizing is an electrochemical process used to create a controlled oxide layer on the surface of metals, typically aluminum or its alloys, to enhance their corrosion resistance, improve surface hardness, provide decorative finishes, or facilitate bonding with other materials.

2.Anodizing production lines can accommodate different variations of the anodizing process.

3.Anodizing production lines may feature process monitoring systems that continuously monitor critical parameters such as current, voltage, temperature, and pH levels. If any parameter deviates from the set limits or predefined parameters, alarms or notifications are triggered to alert operators or maintenance personnel.

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: 26min
   (4) Unprocess time: 7min
   (5) Total time 26+7=33min      

          (6) Average anodizing layer : 0.36*1.3*26*0.77 =9.4um

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 33min ,where total jig(rack)/year:​

                   ( 2 rack x 3 tank x 60min/h) ÷33min x600 hour =6545jig(rack)

2) Design 51.4m²^/jig(rack) . Where every tank is 102.8m²
3) Area treatment/year : 6545jig(rack)x 51.4m² /jig =336413m²

2. Anodizing treatment weight:
        Monthly output : 336413m²÷350m²/T*0.9=865T≧850T

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
