polycarboxylic acid superplasticizer mortar additive

Shanghai Hongyun New Construction Materials Co., Ltd has a group of experts who are good at solving your problems in cement. Our products includes polycarboxylate ether superplasticizer ( PCE supersplasticizer) . For the synthesis of polycarboxylic acid superplasticizers, the design of molecular structure is very important, including main chain group, side chain density and side chain length. The synthesis methods mainly include in-situ polymerization grafting, first polymerization and then functionalization and monomer direct copolymerization. 1. In-situ polymerization grafting method Polyether is used as the medium of unsaturated monomer polymerization, the main chain polymerization and the introduction of side chain are carried out at the same time, the process is simple, and the molecular weight of the synthesized water reducer can be controlled to a certain extent. However, the esterification reaction involved in this method is a reversible reaction, and the g…
