This standard is formulated by adopting the American Society for Testing and Materials standard ASTM D19371998 Determination of mass strength of pelletized carbon black by mass target 3. The main technical differences between this standard and CB/T14853.4-1593 are: the addition of the fifth sampling, this standard is implemented from the date of this standard, replacing GB/T14853.4-1993. This standard was issued by the State Petroleum and Chemical Industry Bureau. This standard is under the jurisdiction of the Carbon Black Technical Committee of the National Rubber and Rubber Products Standardization Technical Committee. The drafting unit of this standard: China National Rubber Industry Research and Design Institute. The main founder of this standard: Deng Biyun. This standard was first issued in December 1993.

4.2 Calibration block: 7mm×250 m. Use this system or measurement. 4.3 Total scale: process (1~30k, used for music 4.4 Ruler as scraper: Used to scrape off excess material on the cylinder. 4.5 Ruler as scraper: Used to scrape off excess material on the cylinder. 5. ... At the same time, adjust the sample screen and mark the reference scale on the density plate. 6-3 Adjust the air regulator to move the barometer pointer from the zero position to a position that is 1/3 or more than 1/3 of the total load of the barometer. 6.4 Press the + button on the timing end to make the rear plug slowly descend and offset against the calibration block, and weigh the equal amount of mass produced by the live seal. 6.5 Single or multiple 6.4. Adjust the air throttle valve until any multiple of 51V is obtained, and mark these values ​​on the surface or on the scale. 6.6 Divide the 50N scale into 5 equal parts, and the annual scale is 10N. Finally, use the material to accurately calibrate these scales: 6.7 Use the calibrated panel to calibrate the scales of other panels, which are required to match the calibrated panel scales and be verified by bamboo. Evaluation and inspection method: Calibrate once a month or more frequently as needed. 7.1 Use a brush to clean the black dust stuck on the cylinder. Close the sliding door, put the overflow cup in a suitable position, put the carbon black sample into the cylinder barrel until a circle is formed on the cylinder barrel, hold a ruler or a knife in a vertical state, stick the table to the edge of the cylinder, and scrape the carbon on the cylinder to make the surface horizontal. 7.2 Adjust the air flow and select the appropriate [K small] until the desired value is indicated on the ruler force meter. 7.3 Press the timer button to activate the mechanical device to let air enter the air, so that the live wire slowly descends to the sample, and then presses on the sample for 10 7.4 When the seat returns to its original position, open the sliding door to observe the cylinder. If a ring or bridge is found after the positive contraction, the carbon black shadow has reached or is close to the test point. Record the value indicated by the pressure gauge. If there is no carbon black left in the cylinder, it means that the test point has not been reached. 7.5 Repeat the above steps according to 7.1 to 7.4 and test another carbon black test. 8 Results 8.1 The approximate pressure of the compressed granulated carbon black in the cylinder to form a ring is used as the numerical value 8.2 Test results Take the average of the two test results and perform static calibration according to G3/T817U to 1N. 9 Precision 9.1 Reproducibility The difference between the two test results shall not exceed 11% of the average value. 9.2 Reproducibility
The difference between the test results of two tests shall not exceed 31% of the average value.
