Acetylene Carbon Black

Acetylene Carbon Black Performance Specifications:

2. Iodine Adsorption Value g/kg: The iodine adsorption value measurement of carbon black is a commonly used method to determine the specific surface area of carbon black. Method: Immerse a quantitative sample of carbon black in a solution of iodine standard at a specified concentration, mix thoroughly, and wait until equilibrium is reached. Separate the carbon black from the iodine solution and titrate the concentration of the iodine solution. Calculate the ratio of the amount of iodine adsorbed to the amount of carbon black, which is the iodine adsorption value of the carbon black.

4. Resistivity Ω.cm: Resistivity is a physical quantity used to express the resistive characteristics of various materials. The resistance of a wire made of a certain material, 1 meter long and with a cross-sectional area of 1 square millimeter, at room temperature (20℃), is referred to as the resistivity of that material. The unit of resistivity is ohm-meters (Ω.cm or ohmm), with common units being ohm-millimeters and ohm-meters.

6. Heating Loss %: Some substances are not completely pure and are prone to absorbing moisture. After heating, the effective components will decrease, and the amount of decrease is referred to as the heating loss.
