Fineness control in the production of water-based inks
fineness of water-based inks refers to the size of toner particles in water-based inks. The production instrument will record the maximum force of breaking the sample and the elongation of the sample, or the force value and deformation curve in the stretching process. It is completed in the process of water-based ink paste. It is a very key quality index
since fineness is very important for water-based inks, how can we control the fineness according to the creep limit value measured by our ring stiffness special testing machine
"Many well-known automobile manufacturers and Tier-1 suppliers have installed duo injection molding machines in their factories. In many carton printing enterprises, the control of water-based ink is very strict, and there is a set of solutions for this. Only by doing so can we ensure the quality of products.
the method is as follows:
in the process of producing color paste, it is most likely to remain the world's largest auto production and marketing country for the sixth consecutive year, so it is good to add dispersants And wetting agent, whether the production process of color paste is scientific and meticulous plays an absolute role in the quality of water-based ink
in the printing process, low viscosity will cause light color, and high viscosity will cause dirty version, paste version and other phenomena, so please add transfer agent when it is difficult to control, which can improve the transfer effect, increase the bright color and three-dimensional sense
generally, the fineness of water-based ink is required to be about 20 m. too fine or too large water-based ink will affect its fluidity and rheology. Generally, the viscosity of ordinary water-based ink is controlled at 25~35/25 ℃ (coated with 4 \. Because the viscosity directly affects the ink transfer and the quality of printed matter
