随着计算机的普及,激光印字机和数码复印机的发展,其使用的耗材(主要是色调剂,即碳粉)也随之兴旺,国际市场的年需求量达12.8万吨,国内市场也达到6000余吨,而且每年按10％速度稳定增长。 复印用碳粉是高分子聚合物,碳粉颗粒的平均直径8-12微米,对粒度分布要求严格,过粗和过小的颗粒总数不多于8％。对碳粉的其他物理特性,如电荷性质(正电或负电)、带电量大小、带电量分布、磁性能、
With the popularization of computers, the development of laser printers and digital copiers, the consumables (mainly toner, ie toner) used by them are also booming. The annual demand in the international market reaches 128,000 tons and the domestic market also reaches 6,000 I tons, but also by 10% per year steady growth. Copying toner is a polymer, the average diameter of the toner particles 8-12 microns, the particle size distribution of demanding, too coarse and too small the total number of particles is not more than 8%. Other physical characteristics of the toner, such as the nature of the charge (positive or negative), the amount of charge, the charge distribution, magnetic properties,
