The use of nano-scale conductive carbon black

　　When buying carbon black, I often hear nano-scale, nano-scale, but many friends do not know what nano-scale conductive carbon black refers to. This article will introduce to you what nano-scale conductive carbon black is and what it has What is the use, what is the technical index and the use suggestion of nano-scale conductive carbon black.

　　What is nanoscale conductive carbon black?

　　Nano-scale conductive carbon black means that the particle size of carbon black is nano-scale. It is generally believed that the particle size is generally considered to be below 100nm and can be called nano-scale.

　　Nano-scale conductive carbon black technical indicators:

　　Iodine absorption value (g/kg) 700-900

　　DBP absorption value (10-5m3/kg) 400-500

　　Nitrogen adsorption specific surface area (103m2/kg) 800-900

　　Heating loss (%) maxl

　　Powder resistivity (Ω.cm) 0.12

　　Average particle size (nm) 30-40

　　Ash (%) ≤5-8

　　What are the uses of nano-scale conductive carbon black?

　　Nano-scale conductive carbon black can be used in plastics, rubber, coatings, and inks. It can be said that conductive carbon black for plastics, carbon black for conductive rubber, carbon black for conductive coatings, and conductive carbon black for inks can all use nano-scale conductive carbon black. .

　　Suggestions for the addition of nano-scale conductive carbon black:

　　In plastics and rubber, the resistance can reach 106 if it is added to 6-7%;

　　Generally, only 5-6% resistance needs to be added to paint and oil to reach 105;

　　In PVC products, it is necessary to increase the dosage appropriately.

　　The above is the introduction of nano-scale conductive carbon black. In fact, the particle size of many conductive carbon blacks has reached the nano-level. When purchasing conductive carbon black, it is not necessary to choose the nanometer level, but to choose the conductive carbon black suitable for your own production process.
