Is carbon black and conductive carbon black used in rubber?
Rubber carbon black and conductive carbon black are mainly distinguished from the function of the product, so the performance requirements of carbon black are different.The carbon black used in rubber mainly focuses on the physical properties of carbon black, and its abrasion resistance and tensile properties are performed according to the requirements of the national standard GB3778-2003. Market commonly used models can be divided into N219, N220, N330, N326, N550, N660, N774, etc., the specific application of the industry is different, but the choice of different models.Conductive carbon black value is the conductivity of carbon black, than the resistance, oil absorption value indicates the conductive carbon black conductive properties, according to the national standard GB3782-2006 GB requirements. According to the purpose of distinction is usually divided into three categories of battery grade rubber grade conductive carbon black, conductive carbon black, conductive carbon black ink level, the specific requirements of the various industries are not the same, there is no specific normative guidance documents, actual test and application specific to choose different manufacturers.
Conductive carbon black is a kind of carbon black used in rubber. After adding rubber, it can make the rubber which has not poured electricity have conductivity characteristics, but the resistivity is higher, and it can't be used as conductor for current load
Carbon black is divided into two major categories according to its use and usage:1. Rubber carbon black2, non rubber carbon black (or special carbon black, dedicated carbon black), including pigment carbon black, conductive carbon black, carbon black used for plastics, and a variety of special carbon black and so onMay refer to: Li Bingyan edited the "carbon black production and Application Manual."
