Air oxidation on the surface of molten tin and tin with other metallic materials (mainly)CuIt is inevitable that some sediment will be caused by the efficacy. One or two days of tin slag is equivalent to an employee's monthly salary, which can be said to be a huge expense. The main reasons for excessive tin slag are as follows: Firstly, the tin material issue. Good tin material will produce less slag, and recycled tin is more likely to generate tin slag. Additionally, the width of the solder furnace nozzle in wave soldering Flow velocity There is also the drop of the tin wave Uniformity of temperature in the tin furnace These are also the reasons for the excessive tin slag in tin furnaces. So how can the solder dross be reduced or the solder wire in the solder dross be decreased? Some equipment in the same industry uses red glue manufacturing to open the double-wave method and cost-effective tin bars, so the proportion of tin slag is very large. Is there a faster way to obtain tin slag to reduce the proportion of tin slag? JJY Solder paste manufacturerLet me share with you all:

Wave soldering machines can reduce tin slag Start from the following aspects:

1Select high-quality tin bars, especially those with the function of eliminating free radicals; Add antioxidant oil or antioxidant powder for antioxidant properties; Dealers who do not use recycled materials in production; 

2The tin furnace should be heated evenly, with as much tin as possible filled with oil to maintain the tin position and reduce the fluctuation. The lower the fluctuation of the wave soldering, the better. The wave soldering should be made as much as possible to lower the bottom point in an allowable situation during operation. Add a tin strip to raise the tin level and maintain the height of the liquid. There is no need to scoop out any tin dross immediately. If it does not affect production, there is no need to keep scooped. A lower liquid level is actually more likely to accelerate oxidation than a higher one. Reduce the height of the Xifei Waterfall and lower the amount of gas contact.

3When the tin slag floats on the surface, there is no need to immediately catch it with a strainer. Instead, use a scraper to grind the tin slag into powder on the inner wall of the tin furnace. Pressing the tin slag with a strainer can also prevent some consumption.

4Carry out various attempts: Add animal oil.Modified tin furnace.Reconstituted powder.Return oil, etc. The effect of the oil should be better. After application, the quality of the electric welding is still good, and there is much less tin slag. It only needs to be used once a week It's enough to catch tin slag once on Saturday.

5ApplicationN2Some nitrogen flushing is carried out, but the machinery and equipment are very important. Many modified machinery and equipment that have not been properly handled are in vain. 6Raw material tin rod plusge And phosphorus. In fact PhosphorusPThe elements are basically added by manufacturers, and there are many types. The antioxidant effect is very good. GermaniumGEThe function of isN2It performed very well in the furnace.

7Oxidants should be used, but most equipment manufacturers stipulate that they should not be used as oxidants are quite corrosive to the furnace liner Please verify carefully before application. According to feedback, it will lead to a reduction in the service life of the tin furnace. Some people have had the leaves corroded and the furnace perforated after using the oxidant. It's a case of losing more than you gain!
