ASTM D4218 Test Method For Determination Of Carbon Black Content In Polyethylene Compounds
ASTM D4218 Test Method for Determination of Carbon Black Content in Polyethylene Compounds
Application:
The carbon black content tester is applicable to the determination of carbon black content in polyethylene, polypropylene, polybutylene plastics, cable and optical cable insulation and sheath materials, and rubber. Comply with national standards GBT 3515-2005, GBT 13021-1991, GB/T2951.41-2008, IEC60811-4-1:2004, etc. A certain amount of samples were pyrolyzed in nitrogen flow at high temperature, and the carbon black content was obtained by analyzing the weight of pyrolyzed samples.
The information provided by this test method is useful for manufacturing quality control, technical service, and research purposes; and is required by various material specifica tions and for the calculation of optical absorptivity.
Technical features:
1. The instrument has a beautiful appearance and is easy to operate;
2. The integrated design of the heating furnace body and control system facilitates user management of instruments.
3. High degree of automation, simply set the temperature value and heating time, and the instrument will automatically heat up to the set value;
4. High temperature control accuracy, wide temperature range, and high uniformity of furnace temperature;
5.7-inch LCD touch screen display, extremely user-friendly interface, can be started with one click operation.
6. Has excellent temperature control function, can set temperature control time, and high temperature control accuracy;
7. The instrument can set any set of different heating time periods, with different heating temperatures, heating rates, and constant temperature times;
8. Comprehensive parameter display, showing the set number of groups, theoretical temperature, actual temperature, heating time (or constant temperature time); During the operation of the instrument, the set parameters and temperature rise or constant temperature time can be viewed. 9. The software comes with built-in calculation function, one click calculation; Automatically calculate carbon black content and ash content.
