Polycarboxylate belong to surfactants, surfactant molecules hydrophilic groups and hydrophobic groups of two parts, after addition of the water solution of hydrophilic groups point, hydrophobic groups point to air, solid and non-polar liquid and make alignment, forming a surface tension adsorption film directed and reduce water and two phases of the interfacial tension. The basic mechanism is that when the cement slurry was added water reducer, superplasticizer molecules adsorb hydrophobic groups oriented to the cement particle surface, polycarboxylate water reducer synthesis, reducing the surface energy. Hydrophilic groups point to the solution, the surface of cement particles single molecule or molecules adsorbed film is formed, the surface of cement particles to bring the same charge, showing repulsion, strong polycarboxylate water reducer, cement particles adsorbed on the surface of the water reduction steric repulsion between molecules cement particles are dispersed, destroyed the cement flocculation, releasing large amounts of free water, Luliang City polycarboxylate water reducer, increasing the fluidity of concrete mixture. Superplasticizer acceptance basis for GB8076-2008 "concrete admixture", JG / T223-2007 "polycarboxylate superplasticizer", GB50119-2003 "concrete admixture technical specifications", GB / T8077-2000 "concrete admixture homogeneity test methods." Wherein GB8076, JG / T223 provides eligibility criteria superplasticizer, GB / T8077, JG / T223 provides test methods, GB50119 specified test items superplasticizer into place to be performed. If the local standard specifies the acceptance of the project and the eligibility criteria for local use when water reducer, polycarboxylate water reducer sales, the company should also be concrete superplasticizer basis for acceptance. Companies should learn from concrete, familiar with these standards, a variety of water reducer acceptance of the project, test methods clear, eligibility criteria, and then plan to form a water reducer acceptance of the company's operating instructions. Luliang City polycarboxylate superplasticizer, polycarboxylate water reducer sales, high-strength construction 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.
