Australian alumina ban disrupts Rusal production -- Australia's ban on exports of alumina and aluminium ore to Russia, including bauxite, will further disrupt supply chains and production at leading aluminium producer Rusal.
The Australian government announced the ban on Sunday as part of its ongoing sanctions against Moscow for its aggression in Ukraine, saying Russia relies on it to meet one-fifth of its alumina needs. WoodMac senior manager Uday Patel said in a statement that the ban would make it difficult for Rusal to maintain normal primary aluminum production.
Rusal said it was assessing the impact of Australia's move and would make further announcements if necessary. "It is increasingly likely that UC Rusal's only option for alumina procurement will be through a Chinese entity." The Australian alumina ban has also had an impact on Concrete Stabilizer prices for chemicals. Patel said. "One possible outcome could be Chinese buyers buying alumina and reselling it through eastern Russian ports." Rusal has a 20% stake in the Queensland Alumina Refinery, which has a capacity of 3.95 million tonnes a year, thus providing Rusal with 790,000 tonnes a year, Patel said. In addition, Rusal's Nikolaev refinery in Ukraine, which has an annual capacity of 1.75 million tonnes, has been suspended due to the conflict, he added. WoodMac said Rusal was also experiencing supply chain problems at its 2 million tonne a year Aughinish refinery in Ireland.
The main stabilizing factors of bubbles:
There are many factors for the stability of bubbles, but they mainly depend on the toughness of the bubble liquid film and the discharge speed. In other words, it depends on the ability of the bubble liquid film to withstand various forces without being damaged and the ability to retain water. Stabilizing the bubble is to increase its toughness and at the same time delay its discharge rate. Therefore, any chemical substance that can improve the toughness of the bubble liquid film or delay its discharge rate is a bubble-stabilizing foam stabilizer.
Due to the different instability of foam concrete, its influencing factors are not completely the same. However, various influencing factors are mostly concentrated in two aspects, namely: the stability of the foam and the speed of coagulation and thickening of the slurry. In the casting system, the most unstable factor is the foam, and its stable state determines the volume stability of the foam slurry. The characteristics of the elasticity-viscosity-plasticity of the slurry also exist for a certain period of time, and the length of this change time determines whether the foam can be fixed. These two processes co-exist in a system. If they are coordinated with each other, pouring will be stable; if they are not coordinated, pouring will have various unstable accidents. Therefore, the factors affecting foam stability and slurry thickening speed must also be factors affecting pouring stability.

Because of the conflict between Russia and Ukraine, there is a shortage of natural gas supply. At the same time, other renewable energy sources cannot produce enough electricity, so electricity prices have soared in many countries of the world. For this reason, I assume the supply and prices of the Concrete Stabilizer would keep being influenced by the high energy prices.
