Scot-Degaser-N2
Scot-Degaser-N2 is an environmental friendly range of chemical degassing
tablets for aluminium and its alloys. Scot-Degaser-N2 is used to remove
dissolved hydrogen gas by diffusion process.
Even under the best melting conditions, it is often impossible to prevent
hydrogen gas from entering the melt which finally gives rise to porosity
in the cast products. It is therefore necessary to remove the hydrogen
from the melt to avoid any such problems in the cast or final section.
Degassing with these products is superior to flushing with chlorine or
nitrogen gas which is associated with problems of space, equipment, corrosion,
health hazards, etc.
| Advantages |
- Removal of Hydrogen from the melt
- Environmental friendly method of degassing
- Minimization of porosity, and defect free
casting
- Easy to use without any storage and handling
problems
- No impurity added into the melt
|
| Instructions for use
|
- The most efficient degassing techniques
are carried out on metal which has been put into maximum temperature
and when the temperature is falling.
- The application techniques using plungers
simply require that the tablet is immersed using bell plunger
to the bottom of the melt.
- Since the efficiency of the operation depends
upon the time of contact between bubble and metal, it is essential
to immerse the tablet as deep into the melt as practicable and
hold it there until bubbling has ceased. Plungers should be pre-heated
and dried.
- Gentle rolling action creates more efficient
degassing than a turbulent action; apply degaser tablets in two
or more successive operations rather than in a single operation.
Degassing should be continued till bubbling ceases.
Note: The use of DEGASSING may result in small amount of fume evolution.
This is non-toxic, no odor and it will not create any problem to the
environment.
