Pyrolytic carbon black (PCB) is one of the most important products resulting from the pyrolysis of used tires. One of the most significant applica-tions of modified pyrolytic carbon black is its use as pigment for offset printing ink to obtain high added values. Inverse gas chromatography (IGC) results show that a large quantity of inorganic matters and carbonaceous deposit are removed by treating the pyrolytic carbon black with nitric acid solution. Plenty of active sites originally occu-pied by inorganic ash and coke are recovered. The surface energy of pyrolytic carbon black (TWPC)modified by titanate-coupling agent-especially the specific interaction γ sspdetermined by the specific probe molecule, tolu-ene-shows the strong interaction between the TWPC and the synthetic resins. The offset printing ink performance confirms the IGC prediction. And TWPC has the great potential of applications in printing ink industry as pigment.展开更多

The amount of fillers （natural zeolite, RHA and perlite） filled in the vulcanizates has been fixed at 20 phr, while CB loading was varied in a range of 0-45 phr. It was found that the tensile strength, percentage of elongation at break, modulus and hardness of the vulcanizates filled with all kinds of fillers increased with the increase of CB loading, while there was no significant change in the compression set. Moreover, at this particular filler loading （20 phr）, the addition of perlite has significant effect on gasohol resistance of the vulcanizates in which gasohol resistance （various ethanol ratio） of the vulcanizates was significantly improved with perlite loading compared with others.展开更多
