ADDITIVE FOR HIGH-CONCENTRATION ASPHALT/WATER MIXED FUEL AND MIXED FUEL PREPARED BY USING THE SAME

摘要

PROBLEM TO BE SOLVED: To obtain a high-concn. asphalt/water mixed fuel excellent in storage stability by using a specific additive in producing an asphalt/water emulsion with an emulsifying machine. ;SOLUTION: A high-concn. asphalt/water mixed fuel is produced by keeping the inside of an emulsifying machine having rotors 61, stators 51, and fine channels 53 and 63 formed on the rotors and stators under a pressure higher than the atmospheric pressure and feeding asphalt, water, and an additive into the machine to mix them with each other to form an emulsion. The additive used comprises 1-50% nonionic surfactant and 99-50% anionic surfactant and/or anionic polymer compd.;COPYRIGHT: (C)1997,JPO
