Effect of Additive Blending Temperature on Toner Properties
Abstract:Surface additive blending is one of the most important processes in toner manufacturing, which determines the toner's xerographic performance. The blending conditions as well as additive composition can affect several important toner properties such as triboelectric charge, charging rate, free flow, cohesivity and cleanabiltiy. An understanding of blending process and its effects to toner performance is of considerable use in designing additive blending and choosing optimal blending conditions.
So far effects of many blending conditions, such as blending rpm and blending time have been extensively studied. However the blending temperatures are normally kept at low temperature to remove the heat generated during high rpm blending and its effect has not been studied much.
Since toner's mechanical properties changes with temperatures as illustrated by the fact that storage modulus of DMA analysis changes with temperature, the adhesion of additives on toner surface may changes. In this study, we try to address the effect of blending temperature and cooling rate on toner properties.

For more than 25 years, NIP has been the leading forum for discussion of advances and new directions in non-impact and digital printing technologies. A comprehensive, industry-wide conference, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems, including drop-on-demand ink jet, wide format ink jet, desktop and continuous ink jet, toner-based electrophotographic printers, production digital printing systems, and thermal printing systems, as well as the engineering capability, optimization, and science involved in these fields.
Since 2005, NIP has been held in conjunction with the Digital Fabrication Conference.
