A Carbon Black Content Tester is an instrument used to measure the carbon black content in materials.

Applications

The Carbon Black Content Tester has wide applications in industrial production, scientific research, and quality control. In industrial production, it can be used to quantitatively analyze the carbon black content in raw materials, thereby controlling the raw material ratio and product quality during the production process. In scientific research, it can be used to quantitatively analyze the carbon black content in new materials, thus understanding the physical and chemical properties of the materials. In quality control, it can be used to quantitatively analyze the carbon black content in products, thereby ensuring the quality and safety of the products.

Standards

GB 13021-1991: Determination of carbon black content in polyethylene compounds.

GB/T 2951.41-2008: Test method for carbon black and ash content in cables and wires.

International Adaptability: Configurable for ASTM D1603 and ISO 6964 equivalency upon request.

Test Procedures

1. Sample Preparation

Weigh 1g of the sample to be tested and place it in the combustion boat according to the test procedure.

2. Instrument Warm-up

Turn on the instrument, purge with nitrogen for a few minutes, and set the heating program.

3. Sample Placement

Place the prepared sample into the quartz tube.

4. Start Testing

Press the test button. Remove the sample after the test is completed.

5. Data Processing

Calculate the test results according to the formula.
