1、 Emulsified asphalt emulsion breaking speed test mixer product structure:

The emulsified asphalt emulsion breaking speed test mixer consists of an electric motor and a stirring blade. The motor drives the stirring blade to rotate, allowing the material to achieve mixing and mass transfer (dissolution, extraction, absorption).Developed and researched the "Mixing Test of Emulsified Asphalt and Mineral Aggregate", which also meets national standards and relevant standards in the petrochemical industry

TD659-2The electric emulsified asphalt and mineral aggregate mixing tester is suitable for mineral aggregate and lotion with specified gradation25℃±1℃Mixing under conditions,

2、 Experimental steps

1、Sift and grade the aggregate (stone chips) used in the actual project, and weigh and mix them according to the proportion in Table T0658-1 into two standard graded mineral materials, each weighing 200g

2Sift and grade the aggregate (stone chips) actually used in the project, and weigh and mix them into two standard graded mineral materials each weighing 200g according to the proportion in Table T0658-1.

3Wash the mixing pot thoroughly and dry it.

4. Mix 200g of group A mineral aggregate evenly in the mixing pot. When it is cationic emulsified asphalt, first inject 5ml of distilled water to mix well, and then inject 20g of lotion. When it is anionic emulsified asphalt, directly inject 20g of lotion, mix it with a metal spoon at a speed of 60r/min for 30s, and observe the uniformity of mineral aggregate and lotion after mixing.
