Carbon black oil absorption meter
english: Absorptometer
Type: C-type
Brand manufacturer: Brabend Instrument Company, Germany
Application:Carbon black oil absorption meterInstruments are widely used testing equipment in the rubber, carbon black, and masterbatch industries. By determining the absorbed Paraffin Oil/DBP content, the structure of carbon black and fillers can be determined.
working principle:Bradender C-type carbon black oil absorption meter from GermanyCan accurately repeat 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.
Technical specifications: The C-type carbon black oil absorption meter is the world's standard carbon black oil absorption capacity analysis and testing instrument. It meets the requirements of the C-type carbon black oil absorption meter and can directly test the oil absorption value of carbon black samples without the need for standard values. The software automatically calibrates.
The high standard testing capability of the C-type carbon black oil absorption meter is due to its highly accurate torque measurement ability and highly accurate mixing chamber design. During the sample oiling period, three phases can be observed on the torque curve: free flowing phase, condensed phase, and terminating phase.
By measuring the torque during the process of sample transformation from liquid to solid to liquid, the oil absorption value of carbon black was analyzed. 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.
