Shapes: pencil, rod and liquid
Used for manufacturing electrode
Used in water-resistant material
Used to produce modified coal tar pitch
Technical requirement (medium temperature coal tar pitch):
Softening point: 85 ?
Insoluble in toluene: 15 to 18%
Ash: 0.2%
Volatile: 60 to 65
Moisture: 4%
Quinoline insoluble matter: 50 to 55%
Notes:
Moisture is only the operation index but not the examination of quality
The ash of Luodi No.2 medium temperature coal tar pitch should be no more than 1%
Number 1 is mainly used for producing electrode
Quinoline insolubles matter should be tested one time per month
