EL5000Oil flux for lead-acid battery
一、Product characteristics
All organic active ingredients, basically non corrosive, no damage to products and molds, performance close to TBS 7 flux. It is suitable for the electrode group casting and welding of lead-acid batteries such as medium and small density lead-acid batteries and electric vehicles. The battery products produced with this flux maintain stable voltage and good consistency in use.
二、Product advantage
● Excellent activity, fast reaction with lead oxide, lead carbonate and other lead compounds, strong activation ability for the surface of lead and its alloy；
● Improve the welding quality and avoid dropping and false welding；
● It can reduce the contact resistance of welding parts to the maximum extent and improve the life and performance of lead-acid battery. Especially high current starting performance。
三、Application scope
It is suitable for group welding of lead antimony, lead calcium and lead multielement alloy plates.

五、Usage method
First, polish the polar ear, then apply the flux to the polar ear, and then immerse it in the lead furnace, the immersion time depends on the temperature of the lead furnace. When coating, only the flux shall be applied to the position to be welded, and the flux shall not be applied to the non immersed position.
六、Matters needing attention
This product will appear turbid at low temperature and become a white paste with fluidity. Please shake it evenly before use, or preheat it with external temperature until it turns yellow and then use it.
