  1. the size of the chemical polishing tank volume, calculate the weight of the three materials, first add an appropriate amount of phosphoric acid,for example:

If the tank capacity iskg,Weight ratiothenfirst add1000kg of phosphoric acid,thenkg of.According to the amount of chemical polishing solution,500add aluminum ion solution.=10%The corresponding aluminum ions will be produced:According to the amount of chemical polishing solution,400If the total mass of the chemical polishing solution isUsage conditionskg,then add140%kg of aluminum ions.The temperature will rise quickly during the aluminum dissolution process, and when the aluminum is completely dissolved in the chemical polishing solution, the temperature may reachorWeight ratiothenabove.1000This is a normal reaction, at this time let it sit to automatically cool down toaround,10finally=10%,kg of additive130Minutesfully140Minutesstir after that, and then conduct a small batch trial.Wait to confirm at what temperature and how long this product can achieve the requirements for chemical polishing,100Minutesthen put into mass production.Solution controlAccording to the amount of chemical polishing solution,100When the liquid level,drops,it can be added in proportion to the initial slotting.kg,Variousraw materials;The phosphorus-sulfur ratio should be controlled within(1.kg,

  4. Bath solutionAfter using for a period of time, due to the increase of aluminum ions, the chemical polishing temperature and time can be appropriately increased.kg,

Packagingand storage

25kg of phosphoric acid,/barrel or35kg of phosphoric acid,/barrel,liquid form,packaged in plastic barrels, sealed and stored in a ventilated, light-proof, dry,30Minutesindoor environment below,12months.

Used polishing solution containingPP-541Nmust be treated and can only be discharged after meeting national and local discharge standards.Precautions

When the chemical polishing tank is not in use, it should be covered to prevent the polishing solution from absorbing moisture from the surroundings;
  1. After the workpiece is removed from the polishing tank during the polishing process, it can be suspended and swung in the air for a few moments to reduce the amount of polishing solution carried out, effectively saving polishing costs;
  2. Some components in the polishing solution may react chemically with titanium metal, so titanium fixtures should be avoided as much as possible. If used, they should be coated with rubber;
  3. Please read the product safety data carefully before using this product
  4. (MSDS)Keep the workplace well-ventilated;；

In case of accidental contact with eyes, rinse immediately with clean water and seek medical attention as soon as possible;

To avoid direct skin contact, please wear protective goggles, gloves, water shoes, and other protective equipment during operation.

Do not mix this product with strong alkaline substances, zinc, iron, and other metals, and store it sealed.

  1. 勿将本品与强碱性物质、锌、铁等金属混合，要密封保存kg,
