沥青水浆不同结构分散剂的成浆性能研究

The slurriability and dosage of some different structure dispersants are studied in the pitch-water slurry(PWS) of Erlian deasphalting pitch and the effect of dispersant adding mode is discussed. The opinion on PWS dispersant is put out that they are consistent when the structure of dispersant and pitch is similar. At the same time, the conception of excellent mol dosage is brought out. The experiment results show that the best PWS dispersant is the pitch sulfonate. It accords with the HLB requirement of PWS and is a good dispersant. Ascertaining the excellent mol dosage can help confirm the best industry dosage. The PWS of high consistence, low viscidity and good stability is produced by the wet crushing and multi adding mode.
