What is nano silica? Nanometer silicon dioxide has many unique properties because it is an ultra-fine nanometer with a size range of 1~100nm. For example, it has the optical property of resisting ultraviolet rays and can improve other materials' anti-aging, strength, and chemical resistance. It is widely used. Nanometer silicon dioxide is an amorphous white powder, non-toxic, tasteless, and pollution-free. Its microstructure is spherical, fluffy, and reticular quasi-particle structure, and its molecular formula and structural formula are SiO2, Insoluble in water. A nanometer is a scale of 10 meters. Nanomaterials mean that in three-dimensional space, at least one dimension is in the range of nanometer size, 1~100 nanometers. Nanomaterials have small size effects, surface effects, and macroscopic quantum drug following effects, thus showing many unique properties. They have broad application prospects in catalysis, light filtering, light absorption, medicine, magnetic media, and new materials.
Application of nano silica The use of nano-silica is very extensive. Generally, the added weight is 0.5-2%, and individual product systems can reach more than 10%. The key to reflecting the product performance is to fully disperse the nano-silica into the system. According to different systems, nano silica is dispersed in water, acetone, alcohol, or other solvents in advance during use. For oily systems, auxiliary agents can be used for pretreatment. It is mainly used in the following fields. (1) Electronic packaging materials: The nano-silica, after active surface treatment, is fully dispersed in the silicone-modified epoxy resin packaging adhesive matrix, which can greatly shorten the curing time of packaging materials (2.0-2.5h), and the curing temperature can be reduced to room temperature so that the device sealing performance can be significantly improved and the device service life can be increased (2) Resin composite material: fully and evenly disperse nano silica particles into the resin material, which can comprehensively improve the performance of the resin-based material, including A improving the strength and elongation; B improving wear resistance and surface finish of materials; C Aging resistance.
Hazards of silicon dioxide Silica is harmful to human health. Silica itself is not toxic, but it is mainly in a solid state. It is widely used in daily life. Silica dust will affect the lungs; for example, after absorption by the lungs, it will lead to silicosis. If it accumulates in the lungs for a long time, it may also lead to pulmonary fibrosis. It may also cause itching of the patient's skin so, which will cause certain harm to the human body.
Price of nano silica Nano silica particle size and purity will affect the product's price, and the purchase volume can also affect the cost of nano silica. A large amount of large amount will be lower. The price of nano-silica can be found on our company's official website.
