Global polycarboxylic acid superplasticizer market trend 2022-2029 Key technology of polycarboxylic acid water reducing agent application by Newsteampindar

Under the spread of the new crown epidemic, after Americans experienced life and death, they set off the largest "resignation wave" in history, and the number of resignations broke the highest record since statistics began in 2000. Since April this year, more than 4 million people in the United States have voluntarily resigned each month. In August, the number of resignations exceeded 4.27 million, and in November, it rose to 4.4 million. The operation of society is linked. The large number of departures in the United States has led to a large shortage of labor; and the shortage of a large number of labor has directly led to the supply chain crisis in the United States; the supply chain crisis has directly affected prices and prices in the United States. The economy has a direct effect on people's lives.
The economic downturn will affect the market demand for polycarboxylic acid superplasticizer.

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.

Europe has been facing the gas shortage problem since the second half of 2021. The worsening situation in Russia and Ukraine has reduced Russian gas shipments to Europe, leading to a doubling of European gas prices. Energy shortages have sent electricity prices soaring. For these reasons, it is predicted that the price of the polycarboxylic acid superplasticizer will continue to increase.
