1、 Working principle

Brabant Instruments, Germany（Bradender）CtypeThe carbon black oil absorption meter can accurately and repeatedly test the absorption testing ability of the oil absorption meter. The principle is to measure the resistance generated by carbon black on the rotating rotor and determine its absorption capacity during oil addition. Apply high-precision burettes to add liquid (as a titrant) to powder samples in the mixing chamber.

When the liquid wets the sample, three different objects can be seen on the torque curve: the free flowing phase; Condensed phase; Terminate the phase.

During the automatic mobile phase, the liquid is fully absorbed into the structure of carbon black. After fully absorbing the liquid, the particles begin to adhere to each other and form aggregates. A sudden increase in torque value indicates an enhancement in resistance to mixing forces.

The torque can reach its maximum value through the phase change from liquid state entering solid state to solid state entering liquid state.

The oil absorption of carbon black is directly related to the processing and vulcanization properties of rubber compounds prepared using carbon black.

2、 Technical indicators

CThe carbon black oil absorption meter is the world's most standardized instrument for analyzing and testing the oil absorption capacity of carbon black, which meets the requirements ofCThe type carbon black oil absorption meter can directly test the oil absorption value of carbon black samples without the need to make standard values first, and the software automatically calibrates.

CType carbon black oil absorption meterThe high standard testing capability is attributed to the extremely high precision torque measurement capability and the highly accurate mixing chamber design. During the sample oiling period, it can be observed from the torque curve that3Individual phases: free flowing phase, condensed phase, terminating phase.

By sampling from liquid state-solid state-The measurement of torque during the process of liquid state change can be used to analyze the oil absorption value of carbon black. The oil absorption value of carbon black is directly related to its processing performance and the vulcanization performance of rubber compounds.

Optional constant temperature jacket, accurately reflecting the mixing characteristics of materials.
