A wave of layoffs that has swept the entire Internet industry has intensified. China's Internet industry has experienced several crises and major changes in the past development process. There is also a "brief history of layoffs by major Internet companies". Hot search, JD.com has a wide range of layoffs in this round of layoffs, and all its subsidiaries are involved. Most of the layoffs are between 10% and 20%. Among them, Jingxi Guangdong and other theaters have all laid off staff. Tencent also reported the news of downsizing and layoffs. Among them, Tencent PCG (Platform User Content Business Group) laid off 30% of its staff, iQiyi laid off 12% of its staff, Kuaishou was reported to have laid off 30% of its staff, and the e-sports department of Station B laid off 90% of its staff.
Mass layoffs on the internet have created a host of socioeconomic issues, including 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.

According to the bank of Spain's latest forecast data, the average inflation is expected to hit 7.6% in 2022, but the average wage increase for workers in this country is expected to be less than 4% in 2022.
If the Bank of Spain's forecast comes true, the gap between price and wage growth in Spain in a single year will be the largest since 1984.
Prices in Spain rose 9.8% year on year in March 2022 and average wages rose 2.4% year on year, with the Bank of Spain forecasting that the country's inflation rate will improve from July.
Recent changes in the international situation have had a big impact on commodity and energy prices. How the prices of the nano silica will develop in the future is still uncertain.
