TEM shows that drying by direct heating might result in hard aggregation of the tourmaline powder, while hard aggregation might be avoided by azeotropic distillation. Raman spectroscopy reveals that there are O_H and C_H on the surfaces of the tourmaline powder obtained by azeotropic distillation, which indicates that butoxy is chemically adsorbed on the surfaces of tourmaline particles, but not adsorbed on those formed by direct drying. X_ray powder diffraction shows that the intensity of diffraction peaks decreases after grinding. There is no damage to the tourmaline crystal lattice in the process of direct heating, azeotropic distillation, or ultrafine grinding.

透射电镜分析结果表明，直接加热脱去水或正丁醇会使电气石超细颗粒发生硬团聚，而共沸蒸馏法则可有效防止硬团聚的产生；拉曼光谱结果表明，共沸蒸馏法制备的电气石粉末表面存在O—H和C—H键，说明正丁醇在颗粒表面为化学吸附，而直接干燥法得到的电气石粉末表面则没有；X射线粉晶衍射结果表明，研磨过程降低了粉末衍射峰的强度，但直接加热干燥和共沸蒸馏干燥均未破坏电气石的晶格结构。

It is simple, that is, in a normal business card printing and membership card making of business card printing and membership card making, using the resin powder (the present use of rosin powder and the like) of spreading in paint, printing ink that is latent in the ink of powder, and then is able to make the business card printing and membership card making part of the carinal.
