| Abstract:The surface of paper mill sludge (PMS) was modified by single surface modifier including sodium stearate (NaSt), sodium dodecyl benzene sulfonate (SDBS), silane coupling agent KH550 and KH560, as wall as compound modifier of NaSt-KH550. The effect of modifier type, modification condition, the dosage and ratio of NaSt-KH550 on the viscosity of the slurry of PMS and oil-absorbed value of PMS were investigated. The surface properties of modified PMS were characterized by FT-IR and OM. The results showed that hydrophobic lipophilic property of PMS was improved by surface modifying, and viscosity of its slurry and oil-absorbed value of PMS reached the lowest when the dosage of NaSt-KH550 was 2.0% and the ratio of NaSt to KH550 was 2∶1, modification temperature was 80℃, modification time was 60 min． |
