Polyethylene glycol, maleic acid (anhydride) monoesters superplasticizer polymaleic acid (anhydride) superplasticizer is maleic acid or maleic anhydride unit with polyethylene or polyethylene / propylene block After the first esterified copolymer polymerization methods. Hirata of maleic acid capped glycol ether and methyl-3-isobutene superplasticizer containing polyoxyalkylene side chains to overcome the gelling problem. Sun Santo et maleic anhydride with polyethylene glycol to esterification macromonomer of polyethylene glycol carboxylic acid ester, followed by addition of 2-acrylamido-2-methyl propene sulfonate and methacrylic acid, an aqueous solution of synthesis by copolymerizing the superplasticizer studied comonomer ratio, measured reaction temperature, reaction time, and to decide the reaction rate constants obtained kinetic equation of the polymerization process. Jiannan to maleic anhydride, emulsifier OP as raw materials, triethylamine as a catalyst for the esterification reaction, the product of maleic anhydride monoesters, maleic anhydride homemade single-methacrylate monomer polymerization to high activity and low activity initiator initiator complex combination of aqueous products caused by water reducing agent system polymerization reaction obtained at various concentrations. He Jing and other new synthetic route through polymer reaction method, Anhui polycarboxylate liquor manufacturers, with S03 sulfonated styrene / maleic anhydride copolymer to introduce a sulfonic acid group, a sulfonic acid group through self-catalysis in synthesized by esterification graft polycarboxylate type superplasticizer with polyoxyethylene side chains on the maleic anhydride groups. 1, DH-4005-type polycarboxylate superplasticizer dosage of 0.4% to 2.5% of the total weight of cementitious material, commonly used dosage of 0.8% to 1.5%. Concrete test should be carried out with a test before use, in order to best dosage. 2, DH-4005-type polycarboxylate superplasticizer not with naphthalene superplasticizer mixed use, polycarboxylate liquor manufacturers must be used when using DH-4005-type polycarboxylate superplasticizer too naphthalene superplasticizer mixers and mixer clean otherwise might lose water reducing effect. 3. When using DH-4005-type polycarboxylate superplasticizer, directly in liquid form mixed with, Shandong-acid liquor manufacturers, can also be formulated into a certain concentration of the solution used and the deduction of Polycarboxylate high performance water-reducing agent into the water itself. 4, due to mixed with DH-4005-type polycarboxylate superplasticizer concrete water reducing rate is high, so the higher the sensitivity to water consumption slump, we must strictly control the use of water.
