[Xinxiang Delong Chemical Co

] the structure of Xinxiang Delong conductive carbon black is the degree of chain or grape like aggregation between very fine carbon black particles, which is determined by the size and shape of the condensate and the number of particles in each aggregate; The more particles make up the aggregate, the higher the structure; The greater the probability of forming a network structure, the better the conductivity: carbon black is composed of condensates composed of a large number of branched and cross-linked primary particles, which is called & ldquo; High structure & rdquo; Carbon black
High structure means that the more developed the chain or grape like structure, it is easy to form a spatial network channel and is not easy to be damaged
High structure carbon black has fine particles, dense mesh chains, large specific surface area and many particles per unit mass, which is conducive to the formation of chain conductive structure in polymers
Generally, oil absorption value (DBP) is used to characterize the porosity of carbon black, that is, the structure
The greater the oil absorption value DBP, the higher the structure of carbon black and the better the conductivity
