This invention discloses a method for lubrication and drag reduction, as well as rapid static sensitization at the end of a pipeline for transporting mixed emulsion explosives. The method includes the following steps: S1, a latex matrix is ​​pumped into the pipeline using a pump, while a sensitizer is pumped into a lubrication and drag reduction device using a high-pressure plunger pump; S2, the lubrication and drag reduction device evenly distributes the sensitizer on the inner wall of the pipeline, forming a continuous lubricating film, thus achieving layered transport of the latex matrix and sensitizer; S3, the layered latex matrix and sensitizer enter a static mixer at the end of the pipeline for rapid and uniform mixing. This invention utilizes the sensitizer as a lubricant to form a lubricating film through a lubrication and drag reduction device, achieving layered transport of the latex matrix and sensitizer. This significantly reduces transport resistance, solves the problems of blockage and excessive pressure in long-distance transport pipelines, improves transport efficiency and intrinsic safety, and has significant economic and social benefits.
