Biden recently announced that the United States successfully carried out a drone operation against an al-Qaeda target in Kabul, Afghanistan, on Saturday, killing al-Qaeda leader Ayman al-Zawahiri.

Al-Zawahiri joined al-Qaeda led by Osama bin Laden in 1998. As the organization's "chief strategist", al-Zawahiri is the top planner of most terrorist attacks, including the 1998 bombings of US embassies in Tanzania and Kenya, and the "9 / 11" terrorist attacks that shocked the world in 2001. Al-Zawahiri was appointed leader of al-Qaeda in June 2011 after the death of Osama bin Laden.

Afghan interim government spokesman Mujahed condemned the United States for carrying out drone strikes in Afghanistan.

Gazprom recently wrote on social media: "preliminary data show that Gazprom produced 262.4 billion cubic meters of natural gas from January to July 2022, a decrease of 12 percent, or 35.8 billion cubic meters, compared with the same period last year."

According to Gazprom's preliminary estimates, in the first seven months of this year, international natural gas demand decreased by 35 billion cubic meters compared with the same period last year. Among them, the demand for natural gas in the 27 member states of the European Union fell by 31 billion cubic meters during this period.

Because of the turbulent international situation, the supply and prices of many international bulk concrete additive are still very uncertain.

What is a water-based defoamer?

Water-based defoamer is mainly used for foam treatment in water-based systems such as water-based coatings and water-based inks. Easy to operate, with excellent defoaming and anti-foaming performance.

 

Waterborne defoamer an emulsion made of dimethyl silicone oil, silica, emulsifier, etc. It has efficient defoaming performance and remarkable anti-foaming effect. For foam treatment, it is not only to quickly and thoroughly eliminate foam, but also to inhibit foam production for a long time in the foaming system, water-based defoamer can achieve these two requirements. In addition to the excellent performance of defoaming and antifoaming, the defoamer also has the advantages of being used in high temperature environment, rapid dispersion in foaming system, good compatibility with foaming system, low cost, wide range of scenes and so on.

 

Different types of waterborne defoamers

Silicone defoamer: strong defoaming performance, relatively heat-resistant, but also antioxidant, but the foam inhibition time is not very long, if necessary, can be used with other ingredients of defoamer. Because of its easy access to raw materials and low price, it is widely used in the paper industry.

 

Defoamer of polyether composition: this kind of defoamer is also very suitable for high temperature environment, excellent anti-foaming performance, strong dispersion in water and widely used.

 

Mineral oil composition of defoamer: here a kind of defoamer is mainly can not use silicone defoamer industry use more, will not produce silicon spot, defoaming and anti-foaming ability are also quite outstanding, but the addition amount is slightly more.

 

The more waterborne defoamers are added, the better the effect will be?

As a kind of emulsion, the defoaming performance of waterborne defoamer is not related to its concentration, but may not be good if it is added too much. For most industries, thinner defoamers will have better defoaming effect, because dilution defoamers are easier to disperse in water, dissolve faster and defoamer faster.

The latest poll by CSA for consumer finance company Cofidis shows the French are taking action to trim their budgets as inflation erodes household purchasing power.  

According to Le Figaro, the poll shows that French people think they need to earn an average of 490 euros more a month in order to live a decent life. This is an increase of 23 euros compared to the purchasing power barometer published in September 2021. Amid inflation and international tensions, this average in the polls masks differences among households, with some social groups much more severely affected by the decline in purchasing power than others. Seventy-eight percent of single-parent households, 76 percent of 25-to 34-year-olds, and 72 percent of blue-collar workers said the international situation had had a negative impact on their personal finances, compared with 64 percent of all French people.  

In response to rising prices, soaring energy, and food prices, in particular, the French government is preparing to launch a package of measures designed to increase the purchasing power, such as extending the energy price protection mechanism, the extension of the fuel discount measures, and more targeted alternative measures, will be distributed inflation-linked pension and social security benefits, check the "food" and so on.

Because of the soaring energy prices, the concrete additive price is predicted to rise in the future.
