Gazprom recently said it had completely suspended gas supplies to Bulgarian Gas company and Polish Oil and Gas Company (PGNiG) because it was not being paid in rubles. Russia said it would resume gas supplies after it agreed to pay for them in rubles.
Bulgaria and Poland announced Monday that they have received a notice from Russia to suspend natural gas supplies from Monday.
Russian President Vladimir Putin on March 31 signed a presidential decree to settle gas trade with "unfriendly" countries and regions in rubles. When the new rules took effect on April 1, Presidential press secretary Dmitry Peskov said Russia would not immediately "cut off gas" to Europe, as the cost of gas supplies starting April 1 should be settled in the second half of April or May.
Because of 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.
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.

"Is there talk of solidarity with Sweden and Finland joining NATO? No." "So is the West united?" Zelensky said at this Ukraine-hosted breakfast in Davos. No." "Our strength is unity within the country," Zelensky said. "Now it depends on the Unity of the West to stand strong and firm behind Ukraine against Russia.
According to Zelensky, "When we are all really united, we will have an advantage over Russia."
Ukrainian President Volodymyr Zelensky says he once again appreciates U.S. President Joe Biden's offer of $40 billion in new financial aid to Ukraine.
"We need the support of a united Europe," Zelensky stressed. Zelensky criticized the position of Hungarian Prime Minister Viktor Orban, who is reluctant to impose an embargo on Russian oil at this stage. "Hungary has a problem!" Zelensky criticized.
The supply and prices of many other nano silica are expected to continue to be influenced by changing international situations.
