A recent poll in Britain found that public support for sanctions against Russia is falling as fuel and prices rise.
The proportion of people willing to accept higher fuel prices as a result of western sanctions against Russia fell 14 percentage points to 36% from 50% in March, according to a survey conducted for the Telegraph by consultancy Redfield & Wilton Strategies.
Global energy and fuel prices have soared since the start of the year and remain high because of the conflict between Russia and Ukraine and uncertainty over Russian supplies.
The survey also found that 54% of people believe their own financial situation has worsened in the past year, up 12 percentage points from 42% two months ago. Sixty-two percent think things will get worse in the year ahead. Less than a third of respondents said they had received a pay rise to keep up with inflation, with two-thirds of those saying it was not enough to keep up with rising living costs.
The figures suggest that public concern about the conflict with Ukraine is now likely to be overtaken by financial worries.
Separately, the UK's consumer price index rose 7 percent this month from a year earlier, the highest since March 1992, according to figures released recently by the Office for National Statistics. In addition, a separate report released a few days ago by the Centre for Economics and Business Research said that real household disposable income in the UK will fall by 3% in 2022, equivalent to a loss of £2,320 per household, which would lead to the biggest drop in living standards since the 1950s. That is mainly because wages aren't keeping up with rising energy and fuel costs.
The prices of other commodities like the concrete foaming agent are also expected to be influenced.
3. The larger the bubble diameter, the better, should be more than 1mm
The pore diameter should be the same as the bubble diameter. Some experts misleading the pursuit of a small foam aperture of 0.1mm, in fact, because of physical foaming if the bubble diameter is large, the stability of the foam cannot be made of foam concrete. The same raw material and formula, the same equipment and technology, just change the bubble diameter, the compressive strength of 1mm bubble diameter of foam concrete, then 0.1mm bubble diameter of foam concrete, at least 20% higher. Therefore, it is wrong to pursue a bubble diameter of more than 0.1mm, which should be corrected in the production of foamed concrete.
4. The lower the foam bleeding rate, the better. Avoid using milk foam.
According to the size of water content, foam is divided into milk foam with more water and sponge foam with more water. Among them, lacteal foam is unqualified inferior foam and cannot be used.
After the foam is made, it gradually secretes water. Its secreting water includes two parts:
Bleeding of foam liquid film. This water is secreted from the liquid membrane, which is secreted by the liquid membrane under the combined action of gravity drainage, surface tension drainage, and liquid membrane damage drainage. The thicker the liquid film of foam is, the larger the bleeding is. The faster the bubble burst, the more bleeding.
Water between bubbles. This is the water that didn't form the bubble film. The worse the foaming agent and foaming machine’s foaming performance, the more water between bubbles cannot form foam liquid film. They're essentially water that doesn't bubble.
When the foam is bleeding at a high rate, it becomes as thin as float juice, sloshing around and not piling up, and there's a lot of water in the foam. When this foam is added to the cement slurry, the cement slurry becomes very thin, and the foam is very little, the volume of the slurry is small, and the resulting foam concrete density is very high, not technical requirements.
Therefore, latex foam should not be used. The appearance of a technically acceptable foam should be a spongy, compact bubble, piled up like white clouds, like bouncing cotton, and not sloshing. This foam has very little water content. This shows that its foam liquid film is small, the foam is not easy to burst, there is little water between the bubbles, and the amount of bubbles is large, accounting for most of the volume of bubbles. It should be emphasized here that the spongy foam must be a small bubble with a diameter of less than 1mm, rather than a few millimeters, or even dozens of millimeters. Bullae are easy to pile up, also like white clouds, but because of the large diameter of the bullae, also unqualified.
The low secretion of foam is mainly to ensure the number of bubbles in the foam and the porosity of foamed concrete, that is, to ensure the density of foamed concrete.
5. The foam has no side effects on cementitious materials
The cementitious material is the main source of strength of foamed concrete, the addition of foam cannot affect its cementitious property, that is, there is no negative cementitious effect. Not every bubble can achieve this.
In the long-term test, we discover a lot of foam to cement, magnesite, gesso of gelling have hindrance, can reduce the strength of foam concrete, sometimes even from beginning to end the concrete after hardening loses strength basically, resemble a dish scatters sand. The stability of these foams is very good, several hours do not disappear, the appearance of sponge, bleeding is very low, dense, and uniform, all aspects meet the technical requirements, but are not compatible with the gel material, so cannot be used for production. This means that foams that are otherwise qualified, such as affecting strength, are ultimately not technically qualified.

Cancer cells can "stretch out a big hand" and take away the mitochondria of immune cells. The Harvard Medical School research team cultured mouse and human breast cancer cells and immune cells, such as killer T cells, and used field emission scanning electron microscopy (FESEM) to observe the relationship between cancer cells and immune cells. interactive. Interestingly, they found that cancer cells stick out long nanotubes, typically within 100-1000 nanometers in diameter, each of which connects to multiple immune cells along the way. The researchers used the drug L-778123, which inhibits the formation of nanotubes, for treatment. The higher the concentration of L-778123, the better the treatment effect.
It is used in various high-tech fields, so the market demand for concrete foaming agent will continue to rise. We are a quality supplier of concrete foaming agent, please feel free to contact us.
