Global polycarboxylic acid superplasticizer market trend 2022-2026 Key technology of polycarboxylic acid water reducing agent application by Newsseriesnow

Recently, the world's largest investment management corporation, BlackRock, in a market research report said that currently, they prefer U.S. and Japanese equities to European equities because of the energy problem stemming from Russia's invasion of Ukraine.

"Russia's invasion of Ukraine caused terrible injuries, a surge in commodity prices, and food and energy security issues," BlackRock, "It is stifling the economic growth and fulling inflation driven by supply problems. Europe is most affected among those developed markets, as it is trying to wean itself off Russian energy."

The volatile international political situations will continue to affect the markets and prices of many commodities like the 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.

Researchers at the Centre for Translational Atomic Materials at Swinburne University of Technology, Melbourne, Australia have developed a new graphene film that absorbs more than 90% of sunlight while eliminating most of the infrared thermal emission losses, a highly efficient A solar-heated metamaterial capable of rapidly heating to 83 degrees Celsius (181 degrees Fahrenheit) in an open environment with minimal heat loss. Proposed applications for the film include thermal energy harvesting and storage, solar thermal power generation, and seawater desalination.
