CRYOGENIC COMMINUTION OF RUBBER

摘要

Rubber chips are immersed in a coolant to cool the chips to a the temperatur e in the range of -90 degrees to -110 degrees Celsius. The coolant contains alcohol such as n- butyl alcohol, methanol, pentane and is cooled by nitrogen. The cooled chips are then comminuted to a powder in the range of 10 mesh to 100 mesh ASTM in size.
