Carbon Black Content Tester

Carbon Black Content Tester Manufacturers,Suppliers China Factory.Carbon Black Content Tester typically utilizes a method called combustion or oxidation to measure the amount of carbon black present in a sample.

Carbon Black Content Tester, also known as a carbon black analyzer or carbon black content analyzer, is a device used to determine the carbon black content in various materials. Carbon black is a finely divided form of carbon widely used as a reinforcing filler in rubber and plastic products.

Here's a general overview of how it works:

Sample Preparation: A representative sample of the material is collected and prepared for analysis. The sample is typically in a powdered or granular form.

Combustion: The sample is placed in a combustion furnace or reactor, where it is subjected to high temperatures in the presence of an oxidizing agent, such as oxygen or air. The carbon black present in the sample combusts or oxidizes, releasing carbon dioxide (CO2) gas.

Detection: The carbon dioxide gas generated during combustion is measured using various detection techniques. One common method is infrared (IR) detection, where the infrared absorption of carbon dioxide is measured. Another technique is thermal conductivity detection, where the change in thermal conductivity caused by the presence of carbon dioxide is measured.

Calculation: The instrument calculates the carbon black content based on the amount of carbon dioxide detected. The carbon black content is usually expressed as a percentage or parts per hundred (phr) in the original sample.

Carbon Black Content Tester Use:

Carbon black content testers are widely used in industries that utilize rubber and plastic materials, such as tire manufacturing, polymer production, and automotive industries. The measurement of carbon black content is important for quality control purposes and to ensure the desired physical properties and performance of the final products.

It's worth noting that there are different types and models of carbon black content testers available in the market, each with its specific features and capabilities. The exact operation and specifications may vary depending on the instrument manufacturer and model.
