Recently, covid 19 outbreak spreads in Shanghai, China. There are more than 25,000 new asymptomatic domestic infections every day. China is implementing a dynamic zero-out policy. A leading respiratory expert said the key to COVID-19 prevention and control is to minimize transmission and fatality rate. Omicron has a low case fatality rate but is highly transmissible and can still claim many lives in large outbreaks. "Total openness is not applicable in China. For China, we should keep to the dynamic zero-out and gradually open up."
However, "dynamic zero clearance" is not the pursuit of complete "zero infection". As the Novel Coronavirus has its own uniqueness and strong concealment, there may be no way to prevent the detection of cases at present, but rapid detection and prompt treatment must be carried out, as soon as one case is found, one case will be dealt with.
The situation in Shanghai is serious. As the financial center of China, Shanghai is a very important city, and the outbreak of the epidemic in Shanghai will put a great impact on China's economy. The current task is to contain the spread of the epidemic as soon as possible, to achieve social zero so that Shanghai's life and economy quickly return to normal.
As China plays an important role in the global supply chain, the outbreak will have a significant impact on the supply and prices of many nano silica.
Silicon Dioxide nanoparticles, also known as silica nanoparticles or nano-silica, can be used as:
Electronic packaging material
The curing time (2.0-2.5h) and curing temperature can be reduced to room temperature, which can significantly improve the sealing performance of the device and increase the service life of the device.
The properties of resin base materials can be improved by fully and uniformly dispersing nano-silica particles into resin materials. It can improve strength and elongation; improve wear resistance and improve the surface finish of the material; improve the aging resistance.
The use of nano silicon dioxide light transmittance, and small particle size, can make plastic become denser, adding silicon dioxide to polystyrene plastic film, can improve its transparency, strength, toughness, waterproof performance, and anti-aging performance. The main technical indexes (water absorption, insulation resistance, compressive residual deformation, flexural strength, etc.) of polypropylene, a common plastic, have reached or exceeded those of nylon 6.
It can improve the suspension stability, thixotropy, weather resistance, washing resistance, etc., so that the combined strength of the film and the wall is greatly improved, the hardness of the film is increased, and the surface self-cleaning ability is also improved.
Silica is known as white carbon black, adding a small number of nano SiO2 in ordinary rubber, the strength, wear-resistance, and anti-aging properties of the product have reached or exceeded high-grade rubber products, and can keep the color unchanged for a long time. Nano-modified color EPDM waterproof roll material, its wear resistance, tensile strength, flexural resistance, and aging resistance are improved obviously, and the color is bright, excellent color retention effect.
Color (dye) material
By adding nano-SiO2 to the surface modification of organic pigment (dye), not only the anti-aging performance of the pigment (dye) is greatly improved, but also the brightness, hue, and saturation index are also improved to a certain extent, which greatly expands the grade and application range of organic pigment (dye).
Nano-SiO2 instead of nano-A1203 can not only play the role of nano-particles, but also the second phase particles, which can improve the strength, toughness, hardness, and elastic modulus of ceramic materials. Nano-SiO2 was used to composite ceramic substrates, the density, toughness, and finish of the substrates were improved, and the sintering temperature was greatly reduced.
Adding nano-SiO2 could make a layer of organic material form on its surface, forming a network structure, forming a silica structure, so that it has hydrophobicity, can inhibit colloidal flow, accelerate the curing speed, improve the bonding effect, increase the sealing and impermeability of the product.
Glass fiber reinforced plastic product
The grafting and bonding of nano-particles with the organic polymer can increase the toughness, tensile strength and impact strength, and heat resistance.
Nano SiO2 can be used as the carrier to achieve a good sustained-release effect.
Nano SiO2 is inorganic composition, easy to be compatible with other components of cosmetics, non-toxic, tasteless, white, has a strong ability to reflect UV, has good stability, UV irradiation will not decompose, does not change color, and will not react with other components in the formula, for the upgrading of sunscreen cosmetics laid a good foundation.
Using the large specific surface area, multi-mesoporous structure, super adsorption capacity, and strange physical and chemical properties of nano-SiO2, functional ions such as silver ions are uniformly designed into the mesoporous surface of nano-Si0X, and the nano-antibacterial powder with high efficiency, durability, high-temperature resistance and a broad spectrum of antibacterial is developed. Can be widely used in bills, medical and health, chemical building materials, home appliances, functional fibers, plastic products, and other industries.

The Japanese minister of Economy, Trade, and Industry recently held talks with the U.S. Secretary of Commerce and industry in Washington, where he is visiting, and agreed to include basic principles on joint research and development of semiconductors and strengthening of supply chains. Japan's economy, Trade and Industry Minister has asked the United States to increase the nano silica will continue to increase in the future.
