A kind of water-based ink preparation grinding dispersion processing technology

Abstract

The invention relates to an aqueous ink preparation grinding and dispersion processing process, which comprises a tank component, a grinding mechanism, a screening mechanism, a first motor, a feed hopper, a second motor and collection bags, wherein the grinding mechanism is arranged in the tank component; the first motor is connected to the upper end of the grinding mechanism and is fixed to the top of the tank component through a fixing rod; the screening mechanism is arranged below the grinding mechanism; the second motor is connected to one side of the screening mechanism and is fixed to the outer side wall of the tank component; the feed hopper is arranged at the top of the grinding mechanism; the collection bags are both arranged on the outer side wall and the central position of thebottom of the tank component; and a supporting frame is welded to the outer wall of a steel structure shell. According to the aqueous ink preparation grinding and dispersion processing process, a grinding process is finer, the screening mechanism is high in running continuity, and a situation that a sieve hole is blocked by graphite and a large amount of the graphite is accumulated can be avoided;and meanwhile, the grinding mechanism and the screening mechanism are arranged in the same shell, so that the energy loss is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of ink preparation and processing technology, in particular to a water-based ink preparation, grinding and dispersing processing technology. Background technique [0002] Ink is an important material for printing. It expresses patterns and characters on the substrate by printing or inkjet painting. The ink includes main components and auxiliary components, which are uniformly mixed and rolled repeatedly to form a viscous colloidal fluid. It is composed of linking materials, pigments, fillers, additives and solvents. It is used for various printing of books, magazines, packaging and decoration, architectural decoration and electronic circuit boards. With the increase of social demand, the variety and output of ink have also expanded and increased accordingly. The pigment is an important fixed component in the ink, which is a fixed powder substance with a certain color. In the preparation process of the ink...

Problems solved by technology

[0003] However, the water-based ink preparation, grinding and dispersing processing technology in the current market has the following problems in the operation process: a. Since the traditional water-based ink preparation, grinding and dispersing processing technology is grinding the ink, the grinding method is relatively single, and a single friction is used. Grinding in the same way leads to insufficient grinding of the ink and a strong sense of particles, which increases the difficulty of operation for subsequent sieving; b. Due to the traditional water-based ink preparation, grinding and dispersing processing technology, the grinding process and sieving are carried out independently Therefore, after the ink is ground, it needs to be transported by transportation equipment, resulting in increased energy consumption and high production costs. At the same time, during the screening process, it is easy to cause blockage of the screening plate and a large amount of graphite accumulation, which affects the normal operation of the equipment.
