发明名称 CARBON POWDER FOR CHEMICAL BODY WARMER
摘要 <p>PURPOSE:To obtain titled carbon powder of low cost, with excellent heat-generating characteristics, by the pyrolysis, in a reducing atmosphere at a specific temperature, of a phnolic resin, followed by carrying out a granulation or grinding operation into a powder of a specific size. CONSTITUTION:The objective carbon powder can be obtained by the decomposition, in a reducing atmosphere at 400-900 deg.C, of a phenolic resin, followed by granulating or grinding the resultant carbonized material into a 5-100 mesh powder. When using, as a feedstock, a phenolic resin containing a halogen-based flame-retardant, incorporation of an alkaline material is preferable.</p>
