What is Nano Silica Used For?

The US President recently said the conflict between Russia and Ukraine had driven up the prices of all the world's major food staples, including wheat, corn, barley, oilseeds and edible oils, and that Russia and Ukraine together supplied more than 25% of the world's wheat exports and about 20% of its barley exports. 

To address the food shortage, the Biden administration says it plans to increase the number of counties eligible for insurance for double cropping. Double cropping is when farmers grow two different crops a year on the same field. 

Under Biden's plan, the number of counties eligible for two-season crop insurance would increase by 681, for a total of 1,935. 

The UN has warned that up to 1.7bn people are "highly exposed" to the domino effect of the conflict between Russia and Ukraine on the global food, energy, and financial systems.  The agency says conflict could increase hunger in countries where people are already suffering from malnutrition.

Even countries where food is less scarce are being hit by rising prices. U.S. grocery prices rose 1% in April, compared with a 10.8% increase over the past 12 months, the Labor Department said recently.

According to the White House, global food prices have risen nearly 13 percent since the outbreak of the Russia-Ukraine conflict. 

Besides, affected by the ever-changing international situation, the supply and prices of international bulk nano silica are still very uncertain.

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. 
 
Resin composite 
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.
 
Plastic 
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. 
 
Coating 
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.
 
Rubber
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).
 
Ceramic
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. 
 
Sealant, binder 
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. 
 
Drug carrier
Nano SiO2 can be used as the carrier to achieve a good sustained-release effect. 
 
Cosmetics 
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.
 
Antibacterial material
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.

With Russia taking the lead on Poland and Bulgaria at the end of last month, there appears to be a growing sense of compromise within the EU over whether to accept Moscow's proposed rouble settlement order. 

Italy's prime minister said recently that European companies would be able to buy gas in roubles without violating sanctions.  This apparently ignores the guidance of hardliners in the EU to "fight to the end". 

For weeks, European companies have been trying to find ways to meet Russia's payment demands for the rouble while maintaining vital gas supplies without violating sanctions against Moscow. 

Late last month, European Commission President Von der Leyen said operating under the mechanism would violate sanctions and asked European companies not to bow to Russian demands. However, the EU has yet to issue more rigorous written guidelines on how companies should pay Gazprom. 

The Italian prime minister said recently, "There is no official announcement from the European Union about what ruble settlement means for sanctions violations, and no one has said whether ruble payments violate sanctions or not. It's a grey area." 

"In fact, most gas importers are already opening rouble accounts for deals with Gazprom,"

He also used German companies as a shield. He said Germany's largest gas importer had already paid in rubles. "In fact, we saw evidence yesterday that the largest gas importer in Germany has already paid in rubles."
