The company was born in Dali, the first town of aluminum in China, which is also a famous town of non-ferrous metals in China, and has more than 1,500 aluminum enterprises so far. Magnesium Extrusion, Aluminum Melting Pot, Ccpi, Extrusion process: The Billets are to be heated and cut to short before entering the extrusion press machine Extrusion ram push the short aluminum billet into container and through the extrusion die. Then aluminum profile comes out, and pulled by the puller tractor, conveyed on cooling table,heated by aging furnace. Finally through surface treatment such as powder coating or anodizing, the aluminum profile product is finished.

1.To determine the concentration of FL-01 and keep it within the range of operating condition,replenish in time.

2.It is better that the aluminum profiles should be rinsing once before the brightening process for avoiding too much aluminum debris and impurities be taken in, which will influence, degreasing effect and increase the consumption of Low Temperature Polishing Additive.

3.The bath should be cleaned regularly during production because there were some insoluble substances like mechanical sundries and dust.

Low Temperature Polishing Additive is packed with sealed plastic barrel, 30kg net each.

Low temperature polishing sink–assay method
Required reagents: 1N NaOH standard solution ②1% phenolphthalein indicator ③ Potassium

①Accurately pipette 20mL of the bath solution into a 250mL conical flask, add 50mL of distilled water, then add 2 to 3 drops of 1% phenolphthalein indicator, and titrate with 1N NaOH until the solution changes from colorless to pink, which is the end point. Write down V1 without fading within 30s.

②Accurately pipette 5mL of the sink solution into a 250mL conical flask, add 50mL of distilled water, add 3g of potassium fluoride, dissolve and shake well, add 2 to 3 drops of 1% phenolphthalein indicator, and titrate with 1N NaOH until the solution is Colorless to pink is the end point, and V2 is recorded if the color does not fade within 30s .
