Scope of application：
      Hc4660 carbon black content tester is suitable for the determination of carbon black content in polyethylene, polypropylene and polybutene plastics. The test of carbon black is obtained by the weight analysis of the sample after high temperature decomposition under the protection of nitrogen. Hc4660 carbon black content tester has the advantages of convenient use, simple operation, accurate measurement, high precision and high automation.

Executive standard：

      《1》GB/T 13021-1991Polyethylene pipes and fittings - Determination of carbon black content (thermogravimetric method)

      《2》ISO 6964-1986Polyolefin pipes and fittings - Determination of carbon black content by roasting and pyrolysis - Test methods and basic specifications

      《4》JTG E50 T1165 Test code for geosynthetics - carbon black content test (thermogravimetric method)

Test principle：

     Weigh a certain amount of the sample to be tested with the analytical balance, place the sample in the carbon black content tester, heat it to a certain temperature under the protection of nitrogen, pyrolysis at constant temperature for about 45 minutes, and then weigh the weight of the product after pyrolysis; heat the product after pyrolysis to 900 ± 50 ℃ with oxygen; calculate the carbon black content in the sample according to the quality difference before and after pyrolysis and calcination Quantity.
