1. the use of 1 ton plastic containers for transportation on an off-plant highway has unsafe factors, the dispersing agent has strong corrosivity, and accidents occur to cause large-area pollution.

2. The process of secondarily unloading full barrels and secondarily loading empty barrels needs to be carried out by adopting a forklift, so that the mechanical cost and the labor cost are increased.

3. According to the structural characteristics of the plastic container, about 100Kg of the dispersant can not be discharged every time, and the plastic container returns to a dispersant manufacturer, thereby increasing the transportation cost.

4. 30 barrels of the dispersing agent are transported to a factory every time and stored on the ground in the factory, certain unsafe factors exist, the dispersing agent is easy to be knocked and scattered to the ground, and certain expense cost is brought to management.

5. When the plastic container is conveyed to a high dispersant tank, the plastic pipeline needs to be frequently moved manually to connect the plastic container and the pump, certain personal safety hazards exist in the movement, and a certain amount of dispersant can be scattered on the ground when the barrel is replaced, so that pollution is caused.
