Xinrui-Te has been tracking the latest development of international water reducing agent ,especially polycarboxylate water reducing agent. Has systematically studied various aspects such as raw material selection, molecular structure design, action mechanism, synthetic production process, cost reduction, and performance improvement of polycarboxylic acid-based water reducing agents. In development, synthesis, and production, Based on the matrix of polycarboxylic acid-based superplasticizers with different performance series, after years of development, the synthesis technology has made great progress.
(1)High water-reducing ester polycarboxylic acid water-reducing agent product adopts MPEG and methacrylate esterification and aqueous solution copolymerization technology. It has small fluctuations in performance and quality and has relatively good adaptability to different cements. The water-cement ratio makes it easier to exert its low viscosity and good slump retention performance. The slump of fresh concrete is more than 200mm, and the concrete loss over time is less than 50mm in 1 hour, which is at the leading level of similar products.
(2) The standard ether polycarboxylic acid water-reducing agent adopts APEG and acrylic acid aqueous solution copolymerization technology, which integrates high water reduction, high dispersion retention, simple process, environmentally friendly production, and stable quality.
(3) High slump retention polycarboxylic acid-based water reducing agent adopts TPEG, acrylic acid, AMPS and other aqueous solution copolymerization technology.
(4)Through the compounding of polycarboxylic acid-based water-reducing agent masterbatch with different properties, various polycarboxylic acid-based admixture products are available to end customers at a concentration of 10 to 20%, with a water reduction rate of more than 30%, using polycarboxylic acid-based pumping agents. The prepared concrete will not segregate, bleed, or slump within 1 to 2 hours, and has excellent performance.
