The oil absorption value of carbon black, as a key indicator for evaluating the surface properties of powder materials such as carbon black, pigments, and battery raw materials, directly affects their dispersibility and application effects in rubber, plastics, coatings, and other fields. Traditional manual detection methods have problems such as large operational errors and low data repeatability.ASAHI S500The carbon black oil absorption tester has achieved a dual breakthrough in detection accuracy and efficiency through mechanical automation and intelligent control technology, becoming a core tool for industry quality control.

1、 Mechanical measurement: eliminating human errors and improving data consistency

The traditional manual titration method relies on the operator's judgment of torque changes, and the differences in the judgment of the endpoint torque by different experimenters can reach up to10%-15%.S500Adopting a servo motor-driven dual rotating wing mixing system, the viscosity changes during the powder oil absorption process are collected in real-time through high-precision torque sensors, and the data fluctuation range is controlled within±1%Within. For example, in the testing of a certain carbon black production enterprise, the same batch of samples were subjected to3The operator manually tested, and the standard deviation of the oil absorption value is2.3ml/100gAnd usingS500duplicate detection10Secondly, the standard deviation has decreased to0.4ml/100gThe data repeatability is significantly better than manual methods.

2、 Full process automation: intelligent control from titration to data output

S500Integrated automatic titration system and temperature control module, users only need to input sample quality and test liquid type, and the equipment can automatically adjust the titration speed（0.1-5ml/minAdjustable), mixing speed control（50-300rpm）And endpoint determination. The mixing chamber is equipped with semiconductor refrigeration/Heating unit can stabilize the temperature of the testing environment at25℃±0.5℃Eliminate the influence of temperature fluctuations on oil viscosity. A pigment manufacturer's test shows that23℃and27℃Manual detection of oil absorption deviation in the environment8%ButS500Compress the deviation through temperature compensation algorithm to1.2%.
