聚羧酸减水剂（Polycarboxylate Superplasticizer）是一种高性能减水剂，是水泥混凝土运用中的一种水泥分散剂，化学上可以分为两类，以主链为甲基丙烯酸，侧链为羧酸基团和MPEG(Methoxy polyethylene glycol)，聚酯型结构。另外一种为主链为聚丙烯酸，侧链为Vinyl alcohol polyethylene glycol，聚醚型结构。

Polycarboxylate superplasticizer (Polycarboxylate Superplasticizer) is a kind of high performance water reducing agent is a kind of cement concrete in the use of dispersants, chemistry can be divided into two categories, with the backbone for methacrylic acid, as the side chain carboxylate groups and MPEG (Methoxy polyethylene glycol), polyester type structure. Another is the backbone for polyacrylic acid side chain is Vinyl alcohol polyethylene glycol, polyether structure.

聚羧酸高性能减水剂是本公司研制的新一代高性能减水剂。掺入本产品后，混凝土具有高坍落度保持性能，在半个小时内坍落度基本不损失，1h坍落度损失很小m时具有外回剂掺量低、减水率高、收缩小等特点。掺入本产品可大大提高混凝土的流动性，使混凝圭能较长时间表保持施工性能；同时能改善混凝土的和易性及物理力学性能，提高工程质量。

Polycarboxylate superplasticizer is a new generation of high performance water reducing agent developed by the company. Mixed with this product after the concrete has high slump retention performance, in half an hour slump basically no loss, 1H slump loss is small m with external back to the low dosage of admixture, reduce the characteristics of water rate is high, small shrinkage. Mixed with this product can greatly improve the fluidity of concrete, the coagulation GUI can keep longer schedule construction performance; at the same time can improve the workability and physical mechanical performance, improve the quality of the project.
