Precipitation white carbon black has high porosity, is very light, and contains a lot of hydroxyl groups on its surface, so it is easy to absorb water.
In the ignition loss experiment, the error sources mainly include: 1) When weighing, white carbon black will absorb water; 2) Because it is easy to be blown off by the wind, affecting the weighing accuracy; 3) After burning, water will be absorbed during cooling and weighing. Article 3 has a greater impact. After burning, it should be put in a dryer to cool down. When weighing, it should be quick to reduce the water absorption of white carbon black.
