SILICA HAVING NARROW PARTICLE SIZE DISTRIBUTION, ITS PRODUCING METHOD, ITS APPLICATION, AND ELASTOMER MIXTURE CONTAINING THE SILICA

摘要

PROBLEM TO BE SOLVED: To obtain silica having a narrow particle size distribution, to provide its production method and its application, and to obtain an elastomer mixture containing the silica. SOLUTION: The silica having a narrow particle size distribution such that d5 10 μm, d50 20 μm and d95 40 μm is produced by drying a silica suspension in a pulse combusting/drying machine.
