Carbon black content tester
Date: 2025-09-22Read: 18
Scope of application:
The carbon black content tester is suitable for determining the carbon black content in polyethylene, polypropylene, and polybutene plastics. The testing of carbon black is obtained by weight analysis of the sample after high-temperature decomposition under nitrogen protection. This instrument has the advantages of easy use, simple operation, accurate measurement, and high degree of automation.
Compliant with standards:
ISO 6964，GB/T 13021，IEC 60811-4-1，GB/T 2951.41，JTG E50 T1165，ASTM D1603-94，GB/T13021-1991，CJ/T 125—2000 等。

YDT 837.3-1996 "Test Methods for Copper Core Polyolefin Insulated Aluminum Plastic Composite Sheath Urban Communication Cables Part 3: Mechanical and Physical Performance Test Methods"
Key Features:
High degree of automation, simply set the temperature value, and the instrument will automatically heat up to the set value;
High precision temperature sensor, accurate to 0.1 ℃;
Fast heating rate, up to 40 ℃/min;
● It has a constant temperature function and can set a constant temperature time;
This type of carbon black content tester can be set to 5 different heating time periods, with different heating temperatures and heating rates;
The parameter display is comprehensive, showing the number of set groups, theoretical temperature, actual temperature, and heating time (or constant temperature time).

Test temperature: Room temperature~1000 ℃ (can be set arbitrarily)
● Display mode: LCD display
Heating tube inner diameter: Ø 31 × (400 ± 50) mm
Power supply: 220V 50Hz
● Dimensions: 700 × 500 × 500 mm (L × W × H)
Operation steps of carbon black content detector:
1. Heat the combustion boat until it is scorching hot, then cool it in a dryer for at least 30 minutes and weigh it. Place a polyethylene sample weighing (1.0 ± 0.1) g into a combustion boat and weigh it together. Subtract the weight of the combustion boat from this weight to obtain the weight A of the polyethylene sample. (The dryer needs to be self prepared)
2. First, place the combustion boat containing the sample in the middle of the quartz tube of the heating furnace, and then insert a rubber plug of an exhaust glass tube into one end of the glass combustion tube. Adjust the atmosphere device to allow nitrogen with an oxygen content of less than 0.5% to pass through the quartz tube at the required flow rate, and maintain this flow rate during the subsequent heating process.
3. Move the combustion boat to the instrument port and do not immediately remove it; After the combustion boat has cooled slightly in nitrogen, remove it and cool it in a dryer for 20-30 minutes before reweighing. Subtract the weight of the combustion boat and measure the weight of the residue (residue weight B).
4. Then place the combustion boat into the glass combustion tube, and in step 4, adjust the atmosphere device to replace nitrogen with oxygen at an appropriate flow rate into the quartz tube of the glass combustion tube, so that the residual carbon black is completely burned. Take out the combustion boat and cool it down, weigh it, subtract the weight of the combustion boat, and determine the weight of the residue (residue weight C).
