Polycarboxylate in concrete more widely, but due to the current domestic regional complex variety of raw materials, in practical application Polycarboxylate the slump loss, bleeding and other problems. Based on years of enterprise technology management and concrete admixtures complex technical services practice found in many commercial concrete company's technology department Polycarboxylate's not enough to understand the mechanism and characteristics, so do not know how to detect and correct the factories fair use. Polycarboxylate is copolymerizable unsaturated monomer containing a carboxyl group is made concrete in water reduction, slump, enhancement, and environmental aspects of contraction with good performance water-reducing agent. Anti-mud type agents synthesis added HPEG2400, TM and some of the water in equipped with a stirrer, a thermometer, a dropping device of four-necked flask, stirred and heated to the reaction temperature. After addition of H2O2, Polycarboxylate technology, while dropping an aqueous solution of 1 (AA and AMPS dissolved portion of the water available) and an aqueous solution of 2 (Vc and MPA dissolved in water to give), polycarboxylate water reducer specification, dropping time is 3h, Hebi City Polycarboxylate After dropping was completed, for 1h to complete the polymerization. Then natural cooling, adding NaOH solution to adjust pH 6-7 to give anti-clay Polycarboxylate HSPC-KN, GPC detected molecular weight MW = 32000. Performance test paste test national standard GB / T 8077-2012 "Test Method homogeneous concrete admixture" in accordance conducted Polycarboxylate of standards, quality of soil cement in accordance with the corresponding substituted within the mixed method. Referring mortar test GB GB / T 19671-1999 "cement mortar strength test methods" steps, cement 550g, sand 1350g, water 220g, within superplasticizer mixed. Concrete test reference GB GB / T 50080-2002 "ordinary concrete mixture performance test method" to carry out. Polycarboxylate sales, high-strength construction materials (certified), Hebi City Polycarboxylate high-strength building materials provided by the Linyi City Limited.
