Carbon black is widely used in industry. It can be divided into furnace method, carbon black, trough method, black carbon, hot cracking method, carbon black and lamp smoke, carbon black and so on. They usually exist in the form of aggregates. In the application field, there are two main categories: Rubber Industry and pigment industry, which are divided into rubber and coloring. Because of different performance of the raw materials for the production of ethylene tar, coal tar, anthracene oil etc.. Due to various tire rubber with carbon black, carbon black is the main performance requirements of wear coefficient, tensile stress, the carbon black density, oil absorption, tinting strength and performance requirements is not high, even every batch of products have a larger gap, but does not affect the use in rubber products. Our company mainly produces pigment black carbon, so here describes the application of pigment black carbon. The carbon black products of a series of technical indexes of density, oil absorption, tinting strength, fineness, pH, more stringent requirements must be inspected before leaving the factory project. In the application field, it is used as pigment. It is used in coatings, paints, inks, sealants, pastes, ceramics, plastics and other fields. Carbon black is one of the most difficult to disperse in all pigments and is used in different fields. Carbon black fineness refers to the original size, and the carbon black dispersion, emissivity, tinting strength, wettability are closely related, following a brief talk. 1, the original carbon black particle size, the smaller fineness, denoted as nm, its density is higher, the stronger the tinting strength. Can meet the production needs of high quality products. 2, but due to small size, gap exists between carbon black particles in the more, the gap between the existence of a large number of air, need longer time on wetting so high carbon black pigment particle size is fine to spend more time in the global invasion dispersed before. 3, smaller particle size, the dispersion will be more difficult in the dispersion when it requires more force, this kind of carbon black in the completion of the original production, the need for a series of postprocessing, in order to increase the active carbon black surface to improve its dispersion. In the field of ink production, more choice of low oil absorption, better tinting of carbon black products. In the field of coatings, the demand for carbon black is not too strict, and can be achieved by using the appropriate dispersing agent and wetting agent. In the sealant production areas, the carbon black particle size is not too small, otherwise the hygroscopic sealant is too high will affect the appearance of the product.
