Product Details

It is suitable for the determination of carbon black content in polyethylene, polypropylene, and polybutene plastics. The test of carbon black is obtained by the gravimetric analysis of the sample under the protection of nitrogen after high temperature decomposition. Features easy using, simple operation, accurate measurement, high precision, and high degree of automation.

Standards

Test principle

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