The overview of Spherical silica powder
Spherical silica powder is also known as spherical silicon dioxide, spherical silicon powder, etc. in the industry.
Spherical silica powder is a white powder with relatively high purity, very fine particles, good dielectric properties and thermal conductivity, and has the advantages of low expansion coefficient, and has strong development potential.
When the Spherical silica powder is used in current integrated circuits, the purity requirements become more and more stringent. Under normal circumstances, the silicon content cannot be lower than 99.95%.
Products using spherical silicon as raw material
1. Acrylic polyurethane varnish: Add 1-3%, which can significantly improve the scratch resistance of the paint film while matting.
2. Coating for printing paper: 15-18% addition amount, the binder is PVA solution, and the brightness of various colors can be maintained after ultraviolet light irradiation.
3. Plastic film additives: Adding amount of 0.05%-0.5%, good opening effect, high clarity, less fish eyes, and at the same time improve the scratch resistance, and the film's effect of adsorbing peculiar smell.
4. Cosmetic foundation: improve smoothness and coating effect.
5. Foamed PVC paste resin board additives: reduce the odor of resin boards.
6.Spherical silicon powder is mainly used for large-scale integrated circuit packaging. It is also used in high-tech fields such as aviation, aerospace, fine chemicals, rewritable discs, large-area electronic substrates, special ceramics and daily cosmetics. It is used in epoxy resin systems. As a filler, it can save a lot of epoxy resin.
Storage conditions of spherical silicon
Spherical silicon (spherical silica) should be sealed and stored in a dry and cool environment. It should not be exposed to the air for a long time to prevent agglomeration due to moisture and affect the dispersion performance and use effect. In addition, avoid heavy pressure and avoid contact with oxidants. But because of its non-toxicity, it can be transported as ordinary cargo during transportation.
The spherical silica is packaged in white woven bags and paper drums, with a PVC moisture-proof inner film and a waterproof outer layer.
