Key technology of polycarboxylic acid water reducing agent application

A wave of layoffs that has swept the entire Internet industry has intensified. China's Internet industry has experienced several crises and major changes in the past development process. There is also a "brief history of layoffs by major Internet companies". Hot search, JD.com has a wide range of layoffs in this round of layoffs, and all its subsidiaries are involved. Most of the layoffs are between 10% and 20%. Among them, Jingxi Guangdong and other theaters have all laid off staff. Tencent also reported the news of downsizing and layoffs. Among them, Tencent PCG (Platform User Content Business Group) laid off 30% of its staff, iQiyi laid off 12% of its staff, Kuaishou was reported to have laid off 30% of its staff, and the e-sports department of Station B laid off 90% of its staff.
Mass layoffs on the internet have created a host of socioeconomic issues, including 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.

The war in Russia and Ukraine is roiling global financial markets. Russia and Ukraine are important commodity suppliers in the world, so their conflict is bound to make a full impact on the global commodity supply. In view of this, the price of the polycarboxylic acid superplasticizer may continue to rise in the future.
