Polycarboxylate Superplasticizers

In recent years, polycarboxylic acid water-reducing agents have been widely used in building construction, especially in the preparation of high-performance concrete due to their excellent water-reducing properties. However, with the excessive development of river sand, there is a shortage of river sand. More and more projects use artificial sand and machine-made sand. At the same time, each construction site is made of local materials. This causes the sand and gravel aggregates to vary greatly in each project. . The fluctuation of the content of various mineral components in cement will also cause differences in cement properties. Therefore, in practical applications, the performance of polycarboxylic acid water-reducing agents is often affected by these factors, causing compatibility problems with cement or aggregates, such as: the water-reducing effect of the water-reducing agent cannot be exerted, and the fresh concrete appears serious The phenomenon of bleeding segregation, rapid loss of concrete slump, abnormal condensation, and easy cracking.

In order to solve these compatibility problems, experts at home and abroad have developed a high-performance water-reducing agent 3-mercaptopropionic acid that is not sensitive to raw material ingredients. China 3-Mercaptopropionic Acid CAS 107-96-0 is mainly used to control the molecular weight in the production of polycarboxylic acid water-reducing agent, a high-performance mediator, and greatly improve the water reduction rate and slump retention performance of concrete. Improve the copolymerization rate of monomer carboxylic acid monomer as a chain transfer agent for colleges and universities. Adjust the relative molecular mass of the water reducing agent. Proper main chain length can achieve both initial water reduction and subsequent collapse protection. Adjust the adsorption process of polycarboxylic acid molecules.
