Product Performance
Nano silica is an white powder with the characteristics of non-toxic, odorless and non-polluting. Its microstructure is a quasi-granular spherical structure in the form of nets and flocs. This special structure makes silica with unique chemical and physical properties.
Nano-silica has a reflectivity of more than 70% for ultraviolet rays with a wavelength within 490 nm. Although it is often used as an anti-settling agent and a dispersing agent in the ink industry , but it is also resistant to UV aging and thermal aging.
Nano silicon dioxide has the characteristics of high strength, toughness and stability at high temperature. Dispersing it in the ink and combining with the macromolecular chain of the resin in the ink can form a three-dimensional network structure, thereby improving the stability and printability of the ink. The size effect and macroscopic quantum tunneling effect of nano-silica make it produce a siltation effect, which can penetrate into the vicinity of the unsaturated bond of the resin, and form a hybrid effect with the electron cloud of the unsaturated bond, improving the thermal resistance of the polymer material. Light and chemical stability.
Nano SiO2 has a three-dimensional network structure, has a large specific surface area, high activity, can form a network structure when the ink dries, increase the strength and smoothness of the ink, and improve the suspension of the pigment, which can maintain the color of the pigment. long-term unchanged. If nano-silica is added, the can opening effect of the ink can be significantly improved, so that it does not delaminate, and it has thixotropy, anti-sag, and good printability. Therefore, whether nano-silica is used as an additive or a modified material, it is of great significance for the cost reduction of the ink industry, especially how to manufacture nano-scale inks that are suitable for the speed and fineness of digital printing.
Storage of Nano SiO2 Powders:
Silica nanoparticle should be sealed and stored in a dry, cool environment, away from direct sunlight.
