Synthesis of the production process diagram: →→ esterification and polymerization reaction →→ →→ →→ liquor finished (1) esterification reaction (preparation of large single-family): Measurement of polyethylene glycol, which is melted in a water bath , added to the reaction vessel, and methyl methacrylate, and 1 part by small material (hydroquinone and phenothiazine ratio of 5: 1), heated to 90 ℃, was added concentrated sulfuric acid (as catalyst), heated to 120 to continue ℃, maintained 4.5h, after sufficient nitrogen 2 hours, (6㎡ / when filling a bottle every 30 minutes, a total of four bottles), the reaction was complete, to give the intermediate water reducer macromonomer polyethylene glycol monomethacrylate acetate and water. (By vacuum distillation → → dehydration, acidification is more complete). (2) Polymerization: Using ammonium persulfate initiator aqueous solution polymerization. Measurement esterification product i.e. polyethylene glycol mono methacrylate, acrylic acid, dodecyl mercaptan molecular weight modifier, with deionized water, pumped into tank A standby titration, is A material. Measurement of ammonium persulfate, with deionized water, pumped into tank B alternate titration, B is expected. Adding deionized water into the reaction vessel, warmed to 85 ℃, while titration A, B material. A complete feed three hours titration, B feed 3.5 hours titration finished, incubated for 1.5 hours. (Temperature control: 90 ± 2 ℃). (3) and reaction (is concentrated sulfuric acid catalyst in the esterification reaction and above being used), the reaction would be cool to below 50 ℃ good polymer polylactic acid liquor manufacturer, soda ash is added with stirring, until the PH value of about 7, the reaction was complete, the mother liquor obtained polycarboxylate superplasticizer. Ultra-retarding superplasticizer GQ-211 Super retarding superplasticizer Executive Standard: GB8076-2008 GQ-210 ultra-slow superplasticizer based on naphthalene superplasticizer as the main component and other complex variety of surface active substances formed, its main feature is a small dosage of polycarboxylate liquor production, retarding effect is remarkable; the construction of concrete hot hot season, solve temperature control, improved construction conditions, concrete dimensions and other extremely favorable combination, can effectively improve the concrete and Easy and reduce bleeding, improve water impermeability and durability, are widely used in concrete, hydraulic concrete dam engineering. Homogeneity ◎ Specifications: ◆ The product is brown or brownish-gray powder. ◆ powder fineness: 0.315mm sieve ≤10%. ◆ paste fluidity ≥180mm. ◎ The main technical performance: ◆ poly-carboxylic acid liquor under the same conditions, the incorporation of this product 0.5-1% water reduction rate of 15-20%. ◆ at the same intensity, it can save 10-15% of cement. ◆ slump at the same time, the incorporation of this product 0.5-0.7%, 28 days strength increased by 30-50% ◆ can effectively improve the workability of concrete, reduce water seepage, improve permeability, water capacity. ◆ can effectively inhibit cement hydration reaction rate, lower heat of hydration polycarboxylate liquor synthesis, delays and delay time peak heat of hydration, reducing the temperature rise inside the concrete, improving crack resistance of concrete. ◆ no corrosion of steel role.
