Russian President says if the European Union imposes an oil embargo, Europe will buy energy at the most expensive price and economic activity in Europe will weaken. Rosneft needs to change its business model. Russia will help facilitate settlement and access to loans and insurance in its own currency.

According to Reuters, the European Commission will unveil a 210 billion euro plan on how Europe can end its dependence on Russian fossil fuels by 2027 and use its distance from Moscow to accelerate a shift to green energy. According to a draft document seen by Reuters, Brussels will propose a three-pronged plan to wean countries off Russian fuel: switch to importing more non-Russian gas, move more quickly to promote renewable energy, and work harder to conserve energy. The draft measures, which include EU law, non-binding plans, and possible recommendations by national governments, are subject to change before publication.

Austria is not a member of NATO and will not seek membership in the future, the Austrian Foreign Minister said in Brussels recently. He stressed that it was "their choice" for Sweden and Finland to seek NATO membership, while Austria would remain neutral.

The supply and prices of many other pce powder are expected to continue to be influenced by international situations.

Polycarboxylate superplasticizer is often used in concrete, which can reduce the water consumption of concrete while maintaining the same fluidity, thus improving the strength and durability of concrete. It has the function of lubrication, wetting, water reduction and plasticization. it is widely used in roads, bridges, tunnels, dams and other construction projects.

A large number of foams will be found in the process of using polycarboxylic acid superplasticizer, and water-based defoamer can be used to solve the problem.

When selecting polycarboxylate superplasticizer, it is necessary to choose products with good compatibility with all kinds of cement, so that the slump of concrete can be maintained well, the construction time of concrete can be prolonged, and the chloride ion content and alkali content in superplasticizer should be low. this is conducive to the durability of concrete. Polycarboxylic acid superplasticizer has the advantages of low content, high water reduction rate and shrinkage, which can greatly improve the early and later strength of concrete.

In the process of using polycarboxylate superplasticizer, because the stirring operation of the equipment will bring a large amount of air into it, foam will be formed, and these bubbles are mainly large bubbles; polycarboxylate superplasticizer will retain some surface active components that reduce the surface tension in the production process, which has a certain air entraining and foaming characteristics, which will lead to foam production.

These foams need to be eliminated in time. When the foam content in superplasticizer is too high, it will have a certain impact on the structure of concrete, and the existence of air bubbles will reduce the compactness of concrete and affect the strength of concrete structure. Too much foam will also affect the performance and quality of polycarboxylate superplasticizer, resulting in excessive bacteria, mildew, deterioration and odor in superplasticizer. The production of foam will affect the production progress and efficiency of polycarboxylic acid superplasticizer and lead to the increase of production cost.

The water-based defoamer has the ability of rapid defoaming and long-term foam suppression, and can quickly penetrate into the interior of the foam to realize foam breaking and defoaming; and has good chemical stability, and will not affect the performance and quality of polycarboxylic acid superplasticizer after use; it will not change its basic system; it has good water solubility and fast dispersion, can dissolve and uniformly disperse with the superplasticizer, and does not bleach oil or precipitate.

Southern Copper Corp (SCCO.N) recently said its Peruvian mine remained closed after a six-week standoff with protesters and blamed the Peruvian government for failing to intervene in the safety of its 1,300 workers and their families.  

The company said in a statement that a recent agreement to end protests at the Cuajone mine required the company to withdraw complaints against protest leaders because railways transporting minerals and supplies remained blocked. Production has been suspended since the end of February.  

Peru's Energy Ministry said in a separate statement that it had also reached an agreement with Southern Copper to start talks to find common ground with local communities.  

"If we shut down for a year, the government will stop receiving more than 3.1 billion soles ($830 million) in taxes and royalties, and 8,000 direct and indirect jobs will be lost. This is what we want to avoid, "Southern Copper added in the statement.

Peru has faced a wave of protests from indigenous communities, who accuse mining companies of not providing enough jobs and funding to poor local residents.  

Central bank officials said last week that protests against copper mines such as MMG's Las Bambas and Southern Copper's Cuajone were dragging down the economy.  

Peru is the world's second-largest copper producer and mining is an important source of tax revenue for the country. It is estimated that the supply and prices of the pce powder will be influenced by that.
