[0002] Carbon black is a black powdery substance formed by incomplete combustion or pyrolysis of hydrocarbons in the gas phase under strictly controlled process conditions. Its main component is carbon, and it contains small amounts of elements such as oxygen, hydrogen and sulfur. Carbon black particles are approximately spherical, with a particle size between 10 and 500 μm. Many particles often fuse or agglomerate into three-dimensional bonded dendritic or fibrous aggregates. In rubber processing, it is added to rubber through mixing as a reinforcing agent (see reinforcing materials) and filler.

[0003] The carbon black oil absorption value, also known as the DBP value, is the volume (cm3) of dibutyl phthalate (DBP) absorbed by 100g of carbon black under specified test conditions. It is used to characterize the degree of aggregation of carbon black.

[0004] When testing the oil absorption value of carbon black, it is necessary to take some carbon black samples and oil samples and add them in batches for mixing. The operator needs to stir the mixture while dripping the oil, which is inconvenient for the operator to perform other operations during the experiment. Moreover, when sampling, it is inconvenient for the operator to complete these steps on the same operating platform, and the operation is more troublesome. Therefore, a carbon black oil absorption value testing device is proposed to solve the above problems. Utility Model Content
