Product Features
This product is a light yellow translucent liquid, which is compounded by organic acid, corrosion inhibitor, aluminum ion complexing agent and precious rare earth. It does not contain any toxic substances. This product is easy to use and is chemically polished in the existing two acids. It can be used directly in the liquid, and there is no danger or harmful gas. This product is mainly used for the two acid polishing of high-grade thin-plate sandblasting, drawing and other products. It has excellent uniformity for products with complex structure or large area. The polishing effect can effectively prevent the bad phenomenon of the aluminum alloy material, such as flushing, brightening of the hole edge, uneven uneven corrosion, etc. in the two acid polishing, and can prolong the air transfer dripping time and be applied to the automatic line production.

Product Features
This product is a deep yellow powder, which is compounded and synthesized by additives such as leveling agent, brightener, precious rare earth and corrosion inhibitor. This product completely replaces the shortcomings of traditional nitrile chemical polishing process, which has a large amount of nitric acid, and has the following advantages:
1 can be combined with a small amount of nitric acid, does not produce yellow smoke, and reduces production and use costs;
2 Good compatibility, it can produce high-brightness polishing effect on most aluminum materials. If it is combined with mechanical polishing, it can get a completely clear mirror effect;

Time                            1-3 min (Reasonably adjusted according to the surface requirements of the workpiece)
In order to increase the service life of the extended bath and obtain a good product surface effect, it is recommended to add a degreasing or dewaxing process before chemical polishing to effectively reduce the contamination of impurities and oil.
In the production process, there is a lack of light, pockmark phenomenon, should first check whether the temperature is too high or if there is to
    much water. If the process parameters are within reasonable limits, add CS-200C or a small amount of nitric acid for adjustment.
When the liquid level is lowered, add the liquid medicine, and add CS-200C (250 g per barrel of phosphoric acid or sulfuric acid) according to te
     addition ratio.
Pay attention to heat preservation when not producing, and cover the moisture absorption.
This product is a neutral drug, avoid contact with acid and alkali drugs during storage, and protect against moisture.
If you use it, you need to wear labor insurance products. If you accidentally contact with the skin, please rinse it with plenty of water immediatey.

一,For ordinary series products
Phosphoric acid: sulfuric acid =2~1:1(Mass ratio or volume ratio)
DX-218: 15-17g/kg(Mass ratio)
                30g/L(Volume ratio)
Specific slotting steps:
1.Firstly, the calculated phosphoric acid and sulfuric acid are added to the stainless steel 316L polishing tank successively; then the proportion of D
     X-218 is added. When adding DX-218, shake it well and add it, stir it to make it dissolve.
2.Operating temperature:90-105℃
3.Polishing time:1-3 min(Depending on temperature and gloss)

二,For high-gloss high-quality requirements (such as shower room, cosmetics series)
Phosphoric acid: sulfuric acid = 2-4: 1 (mass ratio or volume ratio)
Aluminum content: 20g / L (volume ratio automatic line production)
DX-218: 15-17g/kg(Mass ratio)
             30g/L(Volume ratio)
Nitric acid: 3-5% (mass ratio)
Specific slotting steps:
1. The calculated phosphoric acid and sulfuric acid are successively added into the stainless steel 316L polishing tank; the metered aluminum scrap (which needs to be removed from the oxide film layer or the surface of the dirt deposit and neutralized and cleaned) is slowly added to the polishing and discarded. After the aluminum is dissolved completely, add a proportional amount of DX-218 chemical polishing additive when the temperature is lowered to 90-100 °C (when adding DX-218, shake it well and add it), and stir it to dissolve it. Finally, the metered nitric acid is added and the mixture is evenly mixed to carry out the production operation.
2.Operating temperature:90-100℃
4.Polishing time: 3-5 min (depending on temperature and gloss)
1 . Method 1: Prepare the casting tank, add phosphoric acid: sulfuric acid = 1 to 4:1 (mass ratio or volume ratio) one day in advance, add the metered DX-218 (15-16g/kg or 30g/L), add DX- At 218, shake well and add it. Stir well and make it fully chelated. When the liquid level of the working tank is lowered, add the mixture in the preparation tank to the working tank and mix well.
2.Method 2: It is also possible to directly add phosphorus sulphuric acid and DX-218 (15-17g/kg or 30g/L) additives. When adding DX-218, shake it evenly and add it thoroughly.
3.In order to maintain the stability of the working bath, minimize the evolution of the water strip;
4 . In order to increase the service life of the extended bath and obtain a good surface effect of the product, it is recommended to add a degreasing or dewaxing process before chemical polishing to effectively reduce the contamination of impurities and oil;
5.During the working process, if the brightness of the workpiece is reduced, some DX-218 additive or a small amount of nitric acid may be added in an appropriate amount;
6 .  When working with a small amount of nitric acid, please add nitric acid in a small number of ways.
This product is a strong acid agent to avoid contact with alkali drugs;
When using the addition, shake it well and add it;
If you use it, you need to wear labor insurance products. If you accidentally contact with the skin, please rinse it with plenty of water immediatel
     y. If it is serious, you should send it to the doctor in time.
Do not add DX-218 when the content of nitric acid in the original casting tank is too high, because the high content of nitric acid will cause the
     overall effect to decrease!
This product is packed in 25kg plastic drum, which is heat-proof and moisture-proof during storage and transportation.
