Global polycarboxylate superplasticizer market trend 2022-2027 Compound Polycarboxylate Superplasticizer with Defoaming Air-entraining Component by Newsmymanmitt

U.S. natural gas futures rose about 5 percent to a near nine-week high as global energy prices surged on concerns over a pricing plan for energy exports, keeping U.S. LNG export demand near record highs. U.S. natural gas prices have risen despite forecasts of mild weather and lower-than-expected demand, which will allow utilities to fill up storage facilities next week. On Wednesday, Germany launched an emergency plan to manage gas supplies in Europe's largest economy. If natural gas supplies are interrupted or stopped, the German government could take unprecedented steps to limit electricity supply.
Affected by the increase in the price of natural gas, the price of the polycarboxylate superplasticizer will also increase.

In order to overcome the technical defects in the application of polycarboxylate water-reducing agent, or to improve some or some properties of concrete (workability, slump retention, reduction of bleeding, improvement of early strength, low shrinkage, etc.), it is necessary to modify the concrete. 

In practice, the commonly used modification methods include synthetic technology and compound technology. Compared with the synthetic process, the compound method has the advantages of simple operation and low cost, so it is widely used in practical applications. Polycarboxylate series compound technology, is the Polycarboxylate series water-reducing agent and other components (such as slow coagulation, defoaming, air induction, early strength, and other components) according to a certain proportion of the combination compound, in order to achieve the coordination of the superposition of each component.

 

Compound Polycarboxylate Superplasticizer with Defoaming Air-entraining Component 

Polycarboxylate superplasticizer has high surface activity and good foam retention, which will affect the strength of concrete due to excessive gas content. Therefore, in actual use, according to the requirements of construction and use, foam components are selected to reduce the gas content. In addition, air entrainment components are sometimes added to ensure the small stability and uniformity of the internal foam of concrete, so as to meet the performance of concrete.

 

Polycarboxylate series water reducing agent with defoaming agent

He studied the compound effect of oil-type, emulsified type, dissolved type, and solid defoaming agent with polycarboxylate series water-reducing agent. The results showed that dissolved defoaming agents had good compatibility with polycarboxylate series and could compound pumping agents with high flow, high slump, and high strength. If the storage time is short, emulsified type can also be used; And other kinds of defoaming agent should not be mixed, can only be used. 

 

Polycarboxylate series water reducing agent with defoaming agent and air-entraining agent 

Zhang studied the compound technology of defoaming agent, entraining agent and Polycarboxylate superplasticizer, and optimized the compound superplasticizer system that met the requirements of plain concrete. The key to compounding technology is the dosage of defoaming agents and air-entraining agents. By selecting the dosage of defoaming agent and air-entraining agent, the performance requirements of improving workability, increasing strength, increasing compactness, and reducing foaming can be achieved. 

 

Polycarboxylate series water reducing agent with defoaming agent, air-entraining agent, and retarder

Zhang used the compound technology of Polycarboxylate water-reducing agent, defoaming agent, air entrainment agent, and retarder to achieve the synergistic superposition effect of the composite system on workability, slump retention, and setting time of concrete by adjusting the dosage of each component. It is found that foaming can be effectively eliminated and strength improved when the dosage of defoaming agent is controlled at 0.2% of Polycarboxylate superplasmer, cave-retaining property can be significantly improved when the dosage of air-entraining agent is controlled at 0.3% of Polycarboxylate superplasmer, and the effect is better when the retarder (sodium gluconate) is 0.4% of Polycarboxylate superplasmer.

Germany has begun talks with Senegal on gas extraction and LNG supplies. Mr. Scholz recently visited a solar farm in Dakar. He told a news conference that he was willing to work more closely with Senegal on renewable energy. Senegal's president told a news conference that his country was ready to supply liquefied natural gas to the European market.  

The global economy may be facing its greatest test since World War II amid the ongoing threats of COVID-19, the Conflict between Russia and Ukraine, heightened financial market volatility, and climate change, IMF Managing Director Kristina Georgieva warned in an article posted on the IMF's website.

Some 30 countries have imposed restrictions on trade in food, energy, and other key commodities since the outbreak of the Conflict, the article noted. That would raise trade barriers, disrupt global supply chains, drag down economic growth and undo years of economic gains. If countries let it go, the costs will be enormous and everyone will be affected.

The prices of many other commodities like the polycarboxylate superplasticizer are expected to increase in the future. Luoyang Tongrun Nano Technology Co. Ltd. (TRUNNANO) is a trusted global chemical material supplier & manufacturer with over 12-year-experience in providing super high-quality chemicals and Nanomaterials including graphite powder, 3D printing powder, the polycarboxylate superplasticizer, etc. If you are looking for high-quality materials, please feel free to contact us and send an inquiry.
