Ink is a kind of pigment particles evenly dispersed in the connection material and a certain viscosity of the fluid material, in the production of life plays a very important role. In this experiment, based on the preparation of ordinary calcium carbonate inks, modified calcium silicate (particle size smaller than that of ordinary calcium silicate fillers) was used to replace ordinary calcium carbonate, in order to explore whether the particle size of calcium silicate has any effect on the ink printing suitability, and to find out the most suitable replacement rate of modified calcium silicate inks.
