Ink is an important material for printing. It displays patterns and words on the substrate through printing or inkjet painting. The ink consists of main components and auxiliary components, which are evenly mixed and rolled repeatedly to form a viscous colloidal fluid. It is composed of binder (resin), pigment, filler, auxiliary agent and solvent.

The application of water-based inks in actual production is constantly expanding, and continuously reflects the advantages of water-based inks compared to ordinary solvent based inks. Based on market analysis, the application range of water-based ink printing continues to expand, and packaging printing is the main market for water-based ink applications.
With the requirements of environmental protection and the continuous development and improvement of ink and wash technology, ink and wash printing has been accepted by more and more printing enterprises. When ordering products from a printing factory, a considerable number of users specify that the manufacturer use ink to demonstrate their support for environmental protection and their responsibility for the natural environment. At the same time, many users and printing manufacturers also have restrictions and requirements on the content of heavy metals in ink. That is to say, in the formulation of ink, it is necessary to correctly select pigments and try to exclude pigments with high heavy metal ion content.
Anti counterfeit ink is a new field of development and application of ink in the future. Due to the needs of anti-counterfeiting packaging, anti-counterfeiting securities, cheques, and other aspects, the combination of anti-counterfeiting technology and ink technology is generating more promotion and application of anti-counterfeiting ink.
The promotion and application of digital printing technology will provide a new field for the development of ink technology. In the next 10 years, the quality of water ink printing will be further improved, and the usage will also increase. Especially in developing countries where ink and wash applications are not yet widespread, the application of ink and wash will have greater development.

Boehmite and other materials have good thermal conductivity and flame retardance, which not only enables the membrane to conduct heat quickly, improves the thermal stability of the membrane, but also prevents large-scale combustion and explosion of lithium batteries, improving the safety performance of lithium batteries; After being dispersed by a nano sand mill, it has good performance and good compatibility with high polymers, improving the adhesion between the ceramic coating and the membrane, making it difficult to peel off, ensuring that the lithium battery membrane maintains structural stability for a long time, is not prone to deformation, and improves the safety of lithium battery use; Boehmite has low hardness and light specific gravity, which can effectively reduce the wear of production equipment, improve the stability of water-based mixed slurry, and further improve the safety performance of lithium batteries; The thickener in the ceramic slurry does not contain hydroxyl groups, which increases the wettability of the ceramic slurry while also improving the stability of the ceramic slurry and improving the mechanical properties of the membrane.
