Product Description

Product Description:
 Key indicators of nano calcium carbonate for ink
General requirements: The filling amount of calcium carbonate in ink is 3% -10%, and it must undergo activation treatment. The crystal shape is mostly spherical or cubic.
Transparency: Generally, nano calcium carbonate used in ink can be either transparent or slightly transparent. The method of selection is to grind the calcium carbonate with a certain proportion of inking oil to obtain a paste without gray color. The transparency of nano calcium carbonate is related to particle size, crystal shape, and product dispersibility. Generally, the smaller the particle size, the higher the transparency.
Fineness: The average particle size of Type I is required to be less than 30nm, while Type II has an average particle size of 30-60nm, with good dispersion and low insoluble substances in hydrochloric acid.
Viscosity: The viscosity is related to the dosage, dispersibility, and particle size of nano calcium carbonate. Calcium carbonate has good dispersibility in the connecting material, while the viscosity of the ink is low.
Flowability: Type I requires 30-40mm, Type II requires 28-36mm, and flowability is the reciprocal of viscosity, indicating the degree of thinness of the ink. Calcium carbonate products can meet the requirements of different ink flowability by controlling crystal shape and particle size.
Glossiness: Glossiness is a major characteristic indicator of most inks, which is influenced by many factors and is generally specific to customer requirements. In production, the crystal shape and particle size distribution of nano calcium carbonate have a significant impact on glossiness. Whiteness: The requirement for whiteness of nano calcium carbonate used in ink is generally above 80, and a high whiteness can also affect the covering power of the pigment; Some inks also have specific requirements for whiteness, with different systems and application scenarios having their own requirements
