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 polycarboxylic acid superplasticizer, 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 polycarboxylic acid superplasticizer industry, especially in Europe. The price of the polycarboxylic acid superplasticizer 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.
In recent years, polycarboxylic acid superplasticizer has been widely used in many construction fields. Modern concrete has high requirements for additional functional additives, so polycarboxylic acid water-reducing agent in the concrete system, it should consider the following key technologies.
The compatibility technology of polycarboxylic acid series. Because of the special structure of polycarboxylic acid superplasticizer, it can not be stored and used with other superplasticizers, especially naphthalene superplasticizer. Need and different type of water reducing agent for alternate use, must be the relevant container for serious cleaning cleaning, prevent cross pollution to affect the quality of concrete. The adsorption performance of water reducing agent is not the same because of different types of cement, because the polycarboxylic acid water reducing agent is relatively narrow in the compatible range of cement, the incompatible situation is inevitable, so it is necessary to increase its dosage or use different types of cement to effectively solve this problem.
⑵ retarding technology of polycarboxylic acid water-reducing agent. In the construction process, due to the short retarding time, the use of retarding agent can effectively prolong the plasticity of concrete. However, the incompatibility of the two should also be considered to avoid the reduction of concrete performance.
⑶ Gas control. Polycarboxylic acid water reducing agent entrainment effect is very good, can be used together with defoaming agent, entrainment agent. The gas content of concrete can be controlled and its workability and durability can be improved by removing the concrete and then introducing it.
(4) Control of mud content in sand and stone. The application effect of polycarboxylic acid superplasticizer is also affected by the mud content of sand and stone. If the mud content in the sand exceeds 2%, the structures between the clay layers will therefore absorb large amounts of water reducing agent molecules, reducing the flow performance of the concrete. If the mud content is relatively large in the construction process, the anti-clay polycarboxylic acid water-reducing agent should be considered.

Due to the limited total amount of traditional energy, people have a huge demand for cleaner and greener new energy alternatives. Now, the emergence of graphene is unlocking the possibility of its application in the energy field, which can create a greener, more efficient, and sustainable future. Here Francesco Bonaccorso, Deputy Director of Innovation at the Graphene Flagship Program, explains how his researchers have developed a series of initiatives to bring graphene from the lab to the commercial market. Graphene has become a research hotspot for new materials in the 21st century. Graphene has been adopted by many industries, the most notable of which are healthcare and key material applications.
The development of graphene has brought huge fluctuations in the demand for polycarboxylic acid superplasticizer, and the demand for polycarboxylic acid superplasticizer will continue to grow in the future. You can contact us for the latest news on polycarboxylic acid superplasticizer.
