3 Principles
3! The carbon black particles have a dense agglomeration effect on the health of the carbon, and the air volume of the particles is required to be sensitive to the stimulation. The absorption rate of the carbon black particles can be directly obtained from the absorption of the carbon black acid at a certain point, and the absorption value of the carbon black acid can be opened as the most effective carbon black. 3.2 The carbon black particles are used to rotate the film and maintain the state of stimulation. The rotation speed increases, and the torsion resistance of the whole process reaches the predicted value measured by the super chemical curve, and the automatic stop is determined. Directly read the volume of the ester added by the absorber, the absorption volume of each unit mass of the black ester is or the absorption value of the black ester, 4

Record the quality of the trial production and the drip case of 24C3 and 430≤ is the above exploration,
A.6 Evaluation of inspection results

Determination of large torque
B.1.1 For some machines, the determination of SR () as RH (N) may not produce a sufficiently large torque and fail to achieve a satisfactory test accuracy. This also means that the density of the measured carbon may vary with the test. B.1.2 If the test accuracy is not met, special oil restriction and machine adjustment are required, preferably SIF5 or SRB. The maximum torque can be produced at 7% of the scale. This operating procedure will provide the necessary instructions for the approximate torque. B.2 Step
2.? The torque rate should be selected at the scale position that can be used to adjust the torque of the piece. The operation should be carried out according to the operating procedures of 9.4 to measure the RBF5 or SRBF6. II.2.3 When the sample begins to produce a certain degree, the scale moves away from the zero direction of the scale for a certain period of time: the maximum torque produced by the sample is calculated as the percentage of the following formula
