Physical properties of carbon black particles

Carbon black is a colorant, anti-UV aging agent and anti-aging agent for plastics. Static agent. With the development of the plastics industry, the amount of carbon black used in the plastics industry is also increasing. From ordinary daily plastics to high-end engineering plastics, carbon black is inseparable. Compared with carbon black used in the rubber industry, although the amount of carbon black used in plastics is not large, it has a great impact on the performance of plastics. Therefore, the performance requirements for carbon black used in plastics are more stringent and different uses Plastic products have different requirements for carbon black performance. Now we will introduce the application of carbon black in plastics.

Physical properties of carbon black particles

Carbon can be tested using a transmission electron microscope with automated image analysis technology Black particle size, aggregate size and shape, and distribution. By applying transmission electron microscopy to multiple images of carbon black aggregates, the three-dimensional structure of the aggregates can be seen. By rotating the aggregate structure of carbon black with a goniometer on a transmission electron microscope, it can be found that the appearance of the aggregates seen at different angles is different.

Revealed through different angles Aggregate Image, we can create a three-dimensional image of an aggregate. All in all, by rotating we can see that aggregates with high structure carbon black are larger and more complex than aggregates with low structure carbon black. At the same magnification, the image tested by a transmission electron microscope and the three-dimensional image simulated by a computer are shown in Figure 1. Judging from the simulation image on the right, although the image is two-dimensional, we can clearly feel the three-dimensional image of the aggregates; and through observation, we can understand the spatial relationship between carbon black particles. Additionally, such model images can be rotated as needed to observe and measure carbon black aggregates. With the development of three-dimensional image analysis technology, future three-dimensional analysis technology will provide a satisfactory explanation of how the aggregate structure affects application performance.
