被列为国家级重点科技项目和四川省火炬计划项目的高新技术成果“HH沥青乳化剂”,由四川省合江县化工研究所研制成功。这种乳化剂无需有机溶剂和匀化机即能代替阳离子剂乳化沥青。该项目的研制成功为我国公路沥青铺设、层面防水、钢材结构和地下管道防锈、防腐及原乳化沥青厂乳化沥青、简化工艺、降低造价闯出了一条新路。
The HH asphalt emulsifier, which was listed as a national key scientific and technological project and the Sichuan Torch Program project, was successfully developed by the Hejiang County Chemical Research Institute of Sichuan Province. This emulsifier can replace the cationic emulsifier asphalt without organic solvent and homogenizer. The successful development of the project has created a new road for asphalt pavement, waterproofing of floors, steel structure and rust prevention of underground pipelines, emulsified asphalt for asphalt emulsified asphalt plants, simplification of processes, and reduction of cost.
