Russia and Ukraine is an important exporters of oil, natural gas, metals, fertilizers, rare gases and other industrial raw materials. Affected by the further intensification of the tension of the war, the global market has become more worried about the supply of the foam stability, and panic spreads in the futures market. Prices of commodities such as aluminum and nickel are at recent highs on concerns that supplies will fall. Russia accounts for 49 percent of global exports of nickel, 42 percent of palladium, 26 percent of aluminum and 13 percent of platinum, and is a significant exporter of steel and copper. Palladium is an important metal for sensors and memory. In addition, Russia is the world’s largest exporter of nitrogen fertilizer, the second largest exporter of potash fertilizer, and the third-largest exporter of phosphate fertilizer. Ukraine is also an important producer of nitrogen fertilizer. Russia’s natural gas supply also has a significant impact on the global fertilizer industry and foam stability industry, especially in Europe. The price of the foam stability will also fluctuate to some extent. Russia carries out crude gas separation, and Ukraine is responsible for refined exports. Ukraine supplies 70% of the world’s neon, 40% of krypton and 30% of xenon. These three gases are the materials used to make chips.
The technical characteristics of foam stability, the overall technical characteristics of foam with excellent stability are that the liquid film is tough, high mechanical strength, strong resistance to external force disturbance, and can withstand a certain slurry self-weight pressure.
In addition, it has strong water retention capacity, the water on the liquid film is not easy to lose under the action of gravity and surface tension, and can maintain the thickness and integrity of the liquid film for a long time.
This foam also has good adaptability to cement slurry and is suitable for stable existence under high alkaline conditions. In general, this foam can exist stably for a long time and can form good pores in foamed concrete.
Specific analysis, its technical characteristics are as follows:
1. High porosity
Foam with good stability and good porosity for foamed concrete. Its foam porosity can reach more than 95%. The pore formation is uniform and the pore structure is good. During the process of mixing, pumping and pouring, the foam is mixed into the cement slurry, and the foam is very little.
2. Good pouring stability
Pouring stability, that is, during the static stop of the slurry pouring and forming, the foamed concrete will not defoaming a lot, the slurry will not sink or collapse, and the volume stability will always be maintained.
(1) It has good adaptability to the components of cement slurry and will not defoam due to adverse reactions;
(2) The amount of bleeding is low, and the thinning speed of the bubble wall is slow;
(3) The foam has good toughness and strong resistance to the self-weight pressure of the slurry.
The subsidence and collapse of the slurry caused by defoaming after pouring are the most serious process accidents in the production of foamed concrete. To avoid such accidents and ensure normal production, it is necessary to require the foam to have the stability of the pouring static stop period.
3. The formed pore structure is excellent
For foam with good stability, after the slurry is hardened, there are few pores and connected pores formed by air-crossing. Foam with poor stability, the foam is easy to string air and holes, there are many connected holes, and the deformation of the cells is large and not round. And the small bubbles burst and merged into large bubbles, forming uneven large pores. These will affect the performance of foam concrete.

Due to the Russia-Ukraine conflict and the covid-19 pandemic, how will the international situation develop is highly uncertain. It is too difficult to assess its economic impact properly. However, we could see energy prices and commodity prices keep rising and supply chains are disrupted. Therefore, foam stability prices are expected to rise in the future.
