Description

Technical Field

[0001] The invention relates to the technical field of carbon black testing, and in particular to a method for testing the oil absorption value of special carbon black. Background Art

[0002] Specialty carbon black is a high-performance carbon black with excellent conductivity, wear resistance and coloring properties. It is widely used in rubber, plastic, coating, ink and other fields. However, the production process of specialty carbon black is complicated, the cost is high, and there are certain difficulties in testing its performance parameters. Among them, the oil absorption value is one of the important performance parameters of specialty carbon black. The oil absorption value indicates the absorption capacity of specialty carbon black to oil, which directly affects the application effect of specialty carbon black. Therefore, accurately measuring the oil absorption value of specialty carbon black is of great significance for the production and application of specialty carbon black.

[0003] At present, the commonly used test method for the oil absorption value of special carbon black mainly adopts the ASTM D-2414 standard, which is to put a certain mass of special carbon black into a specific container, then add a certain amount of oil, stir it and measure the increase in oil, so as to calculate the oil absorption value of the special carbon black. However, in actual operation, due to the special structure of special carbon black, its oil absorption value is often high, resulting in the torque value being too high and unable to be measured during the test.

[0004] The existing test method for the oil absorption value of special carbon black has the following problems. First, due to the high oil absorption value of special carbon black, the torque value is too high during the test, resulting in an inability to measure. This not only affects the accuracy of the test results, but also limits the scope of application of the method. Secondly, due to the complex production process and high cost of special carbon black, if problems occur during the test, it will cause great economic losses. Therefore, how to improve the test method for the oil absorption value of special carbon black and improve the accuracy and efficiency of the test is a problem that needs to be solved urgently in the current field of special carbon black manufacturing technology.
