From April the French government will reduce fuel taxes slightly to ease the burden on consumers.
Warned of possible energy shortages in France by the end of the year and called on the French to conserve electricity and gas from now on, saying that if nothing was done, The energy situation will be tough this winter. Some experts say that there are two main reasons for France's energy crisis: first, the conflict between Russia and Ukraine affected the gas market and caused supply tension; The second is a safety review of France's newest nuclear power plant, which may lead to a reduction in output this year. In order to alleviate the energy crisis, the whole French society needs to be mobilized, whether it is the industrial sector, the tertiary sector or every French citizen. Now it is urgent. Rising fuel prices may also have an impact on shipments of the nano silica.
Nano silica or nano SiO2 is a very important new inorganic material. It is amorphous white powder, non-toxic, tasteless, and non-polluting. It has the advantages of small particle size, large specific surface area, strong surface adsorption, large surface energy, high chemical purity, good dispersion and special properties in thermal resistance and resistance. Nano-silica plays a very important role in industrial application and scientific research because of its excellent stability, reinforcement, thickening and thixotropy.
Nano silicon dioxide structure is a quasi-granular spherical structure with reticular and flocculent shape. This special structure makes silicon dioxide have unique chemical and physical properties. The reflectivity of nano-silica to ultraviolet radiation less than 490 nm is more than 70%. Although it is often used as an anti-sedimentation agent and dispersant in the ink industry, it can also resist ultraviolet aging and thermal aging.
Nano silica still has the characteristics of high strength, toughness and stability at high temperature. when dispersed in the ink and combined with the macromolecular chain of the resin in the ink, the three-dimensional network structure can be formed. in order to improve the storage stability and printing adaptability of the ink.
The size effect and macroscopic quantum tunneling effect of nano-silica cause its silting effect, which can infiltrate near the unsaturated bond of the resin and form a hybrid effect with the electron cloud of unsaturated bond. improve the thermal, optical and chemical stability of polymer materials.
Nano silica has a three-dimensional network structure, large specific surface area and high activity, which can form a network structure when the ink is dry, increase the strength and finish of the ink, improve the suspension of the pigment, and keep the color of the pigment unchanged for a long time. If nano-silicon dioxide is added, the can opening effect of the ink can be obviously improved, so that it is not delaminated, and it has thixotropy, anti-flow hanging and good printability.
Therefore, whether nano-silica is used as an additive or a modified material, it is of great significance for the low cost of the ink industry, especially how to produce nano-sized ink adapted to the digital printing speed and fineness.
Nano silica used in polyamide ink
At present, the ink industry uses alcohol-soluble polyamide resin instead of alcohol-soluble polyamide resin, which uses dimer fatty acid as a monomer and adds isobutyric acid to introduce branched chain on the polyamide main chain, so as to improve the alcohol solubility of the resin and its stability in alcohol solvents. However, there are some shortcomings in the quality of alcohol-soluble polyamides, such as darker color, poor transparency, low gloss, poor solubility of alcohols than benzene, and serious gelation. The nano-silica particles were fully dispersed into the polyamide ink system through the sand mill. Due to the small size effect of the nano-silica, the viscosity of the polyamide decreased, the ink film formed was flexible and non-stick, and the wear resistance was better. The printing adaptability has been effectively improved.
Nano silica used in cooking-resistant composite ink
The role of nano-silica in the cooking-resistant composite ink is mainly to maintain the good fluidity and fineness of the ink to prevent pigment settlement; when printing, it can improve the flow and hanging performance of the ink film when printing on the machine, and prevent the occurrence of water lines; when coating, it is beneficial to the uniform coating of the adhesive, avoid the generation of air bubbles and improve the composite fastness. Due to the high fluidity and small size effect of nano-silica, the surface of the material is more compact and smoother, the friction coefficient becomes smaller, coupled with the high strength of nanoparticles, the wear resistance of the material is greatly enhanced. In addition, nano-silica has a better anti-aging effect on inks used for outdoor decoration, advertising and other printing products, and it can effectively reflect ultraviolet rays. After being added to the resin, it can greatly reduce the degradation of ultraviolet rays on the resin and improve the sun resistance of printed products, thus delaying the aging of materials. Therefore, for ink resin, the addition of nano-silica makes its anti-aging, friction resistance have been greatly improved, and also has the effect of anti-sticking and anti-sinking.

Against the backdrop of the conflict between Russia and Ukraine and Western sanctions imposed on Russia's natural gas exports, the price of natural gas and liquefied natural gas in the international market has soared, and the trend of returning to burning fuels such as oil and coal because natural gas cannot afford it has become increasingly prominent, Bloomberg reported recently. Data show that in early August, the price of natural gas on the international market was almost twice that of diesel, while the price of natural gas in Europe was almost three times that of high-sulfur fuel oil and propane. Industry insiders pointed out that many governments have recently announced that they will allow power stations to increase the use of oil and coal fuel because of concerns about the shortage of natural gas supply this winter. The International Energy Agency estimates that global oil demand will grow by 380000 barrels a day to 2.1 million barrels a day, based on the shift to oil in power stations and factories.
As the situation in the field of power generation varies from country to country, there are great differences in the extent to which countries use fuels such as oil and coal. Countries such as Pakistan and Bangladesh have large facilities that can switch between natural gas and fuel. In some countries, coal-fired and oil-fired power stations have been decommissioned for a long time, and the maintenance conditions of the equipment are different, so it is doubtful whether they can resume operation quickly.
