Synthesis of copolymer of poly-carboxylic acid copolymer superplasticizer reaction with water as a solvent, persulfates or redox initiator system compound, mercapto compounds or methallyl sulfonate as a radical solution polymerization chain transfer agent . There are three methods of quality control copolymer: (1) seed polymerization: The portion of the monomer and the portion of the solvent and a small amount of initiator added to the reaction flask, Hebei price of ready-mixed mortar admixtures, heating the polymerization reaction was continued after the start of the remaining single body, solvent and initiator continuously added to the reaction flask. (2) was added law: all the monomers and all the solvent to the reaction flask and heated continuously added initiator. It was added to (3) part of the solvent system, the reaction 先向, raised to a certain temperature, and then double-drop method was added thereto and polymerization initiator mixture of monomers. In the country the past few years, Shijiazhuang ready-mixed mortar admixture price, in order to meet the development requirements of high-performance concrete and construction technology of concrete, ready-mixed mortar admixture price, needs to have a large water reduction, good workability cementitious materials Adaptability good superplasticizer, while polycarboxylates just to meet this demand, and therefore should be widely applied. Aiming Polycarboxylate nature and concrete performance carried out tests of concrete, pointing out the presence of Polycarboxylate deficiencies. Shanxi price of ready-mixed mortar admixtures, ready-mixed mortar admixture price, high-strength construction materials (view) provided by the 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.
