Our company specializes in the collection of solder slag, and the collected solder slag is primarily processed in the following ways:
Sell the tin slag directly, which is to say, dispose of it as scrap.
A simple, convenient, and cost-effective solution—contact our company for more information. We are a professional tin slag recycling firm.
2. Direct exchange of solder wire with manufacturers:
Most of the profit goes to the manufacturers of solder wire. If leaded and lead-free solder wire are accidentally mixed during storage or transportation, the price difference is significant, naturally resulting in a low exchange rate!
3. Utilize tin slag reduction machine:
The tin slag reduction machine is a relatively simple device. It mostly involves heating solder to melt it into a liquid and then using gravity to separate the molten solder from oxides. Oxides do not melt. Since it employs a physical reduction method, oxidized tin slag cannot be reduced to recover tin. What is所谓的还原出来的锡 is merely pure tin mixed in during the consolidation process. The high temperatures, pressure, and friction of the reduction machine during operation actually re-oxidize the pure tin mixed in during consolidation. It occupies space, requires dedicated operation, consumes electricity, generates noise, and the process of recovery is complex, involving recovery, transportation, storage, and increasing management costs. With a low reduction rate to begin with, subtracting the rent for equipment space, storage space, employee wages, electricity, and equipment investment, it's often more cost-effective to directly exchange tin bars with the manufacturer!
Common Sense: Any oxide can only be reduced through ionic or atomic displacement, i.e., a chemical displacement reaction. Physical reduction methods are not capable of conducting reduction reactions.
Use antioxidant oil or antioxidant additives:
By covering the surface of molten metal, it isolates it from air to minimize oxidation. Tin slag primarily forms when the raised wave peaks of molten tin reflow into the tin pot. Just like the slag covering the surface of molten tin, it can also isolate air to reduce the formation of tin slag! It's better not to use it than to use it!
4. Reducer or Reducing Agent
Most are inorganic metal salts, the vast majority of which are corrosive to metal. They emit large amounts of smoke, odor, and dust, and may contain sparks, posing a risk of igniting a fire or potentially clogging nozzles, making equipment maintenance difficult. Due to their conductive nature, once accidentally沾to a PCB board, they are hard to clean off and can affect the product's electrical performance and the reliability of solder joints!
