The application of nano calcium carbonate in ink products demonstrates excellent dispersibility, transparency, good gloss, as well as excellent ink absorption and high dryness. Nano calcium carbonate is used as an ink filler in resin ink, which has good stability, high glossiness, and does not affect the drying performance of printing ink Strong adaptability and other advantages.
Difficulty in dispersing nano calcium carbonate:When nano calcium carbonate is dispersed in water or solvents, it is prone to agglomeration, resulting in an increase in material particle size, poor dispersion effect, and insufficient product modification.
If ordinary dispersing equipment is used, it is difficult to evenly disperse nano calcium carbonate, and agglomeration may occur, making it difficult to open the agglomerates. However, if SID's latest developed dispersing equipment, a grinding and dispersing machine, is used, the agglomeration problem can be solved by first grinding and then dispersing the machine, and the nano calcium carbonate can be reduced to the nanometer level.
SID grinding disperser is a device composed of colloid mill and disperser, mainly used to solve the dispersion of nanoscale materials, such as nano calcium carbonate, nano magnesium hydroxide, nano alumina, graphene, carbon nanotubes, etc.
The GMSD2000 series grinding and dispersing equipment is a new product developed by SID Company after research. This machine is particularly suitable for materials that require grinding, dispersing, emulsifying, and homogenization in one step. We will modify the three-stage high shear homogenizer emulsifier by replacing the three-stage with the first stage, and then adding a colloid grinding head on top of the emulsifier head, so that the material can be first finely ground by colloid before being dispersed, emulsified and homogenized by the emulsifier. The colloid mill can be replaced according to material requirements (we provide five types of emulsifying heads for customers to choose from, including 2P, 2G, 4M, 6F, 8SF, etc.)
