Acetylene Carbon Black Performance Specifications:

2. Iodine Absorption Value g/kg: The iodine absorption value measurement of carbon black is a commonly used method to determine the specific surface area of carbon black. Method: Soak a quantitative amount of carbon black sample with a solution of iodine standard at a specified concentration, mix it thoroughly, and wait until it reaches equilibrium. Then 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 absorption value of the carbon black.

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

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