Flame flux |
|
The main point of flame flux is that the flux is directly added into flame in the welding porcess. This state-of-the-art product is codevelopped by Tianjin University and our company.
Generally the flux is used to consistently remove oxidative layers on the metal and melting solder,thus the metal and solder is kept away from oxidization,and they can combine easily to form welding line.
1. Introduction :
The product is a colorless organic liquid,flammable and volatile. It turns into flux in flame. It is not corrosive and can be stored in iron or copper vessels.
2.physical property:
- boiling point:52-58°C
- density:0.85-0.88(20°C)
- flash point:-8°C
- volatile,no residue in dry air
