Ester crosslinking type agents Chongzhi an acrylic ester synthetic macromolecules partially cross-called MPCs (with three polyoxyethylene chain link) Polycarboxylate superplasticizer. Of poly (ethylene oxide) chain length in the cement of liquidity, the role of Zeta potential and cement compatibility, etc., and that the MPC-7 is a good performance of polycarboxylate based superplasticizer. Grafted type agents grafted copolymer superplasticizer is the latest product of superplasticizer research and development, including the orientation reaction such superplasticizer polyether compound with a carboxylic acid polymer body, polyether-modified high acid polymer composites, etc., usually of a molecular weight of 1000-2000 and an end carboxylic acid polymer is an alkoxy group, and the other end is a hydroxyl group or an amino group in the polyoxyethylene non-aqueous solvent graft modified; or to polyene polyamine polymer modified to obtain a graft rate is high and stable performance of products ready-mixed mortar admixture plant in Hefei, its water reduction and slump retention performance are superior. Introduced in the molecular structure of amino improve cement composition fluidity retention performance, and facilitate cement hydration; graft Fuzhou mixed mortar admixture plant through an ester linkage or imide bond modified, effectively extending the storage period. Polycarboxylate superplasticizer as the third generation superplasticizer on behalf of ready-mixed mortar admixture plant, is the dominant direction of development of the industry in today's water reducing agent, in addition to a green, high strength, high water reducing rate, low dosage, dispersion and dispersion retention and good performance advantages, its other main feature is the large degree of freedom of molecular structure, can achieve excellent performance expected by the molecular structure of a multi-purpose design superplasticizer [1]. Current national polycarboxylate superplasticizer for more research and application, with Japan to promote the application of the more successful. 1986 Nippon Shokubai Co., developed the first successful Polycarboxylate superplasticizer has a certain proportion of hydrophilic functional groups, followed by the gradual application of concrete admixture plant engineering ready-mixed mortar, ready-mixed mortar admixture plant in Jiangxi, high-strength building materials (certified merchants) are provided by high-strength Materials Co., Ltd. Linyi City. Linyi high-strength building materials Limited (www.lygqjc.cn) is specialized in "polycarboxylate superplasticizer, polycarboxylate liquor, poly carboxylic acid liquor," the business, the company adhering to the "honesty, hard service" concept, in order to You provide the most quality products and services.
