Naphthalene pumping aid in the development of recent decades has also exposed some of its insurmountable problems. For example, concrete slump loss with its obvious influence formulated, there can be a higher water reduction, the main raw material for its production - a byproduct of coking industry is naphthalene, source, etc. subject to the steel industry. For this purpose, at home and abroad to actively research and develop non-Naphthalene efficient pumping agent, to enrich the petrochemical products as raw materials to high water reduction, minimal slump loss overshadowed naphthalene-based pumping agent, thus creating a new situation in pumping technology and construction technology of concrete. Trend of the times, the use of the State Key Laboratory of a renowned university after seven years research and development of key technology research synthesis technology, the successful production of a new generation of superplasticizer copolymerization carboxylic acid liquor Liaoning polyethylene, and formed a certain scale production. After incorporation copolycarboxylate pumping fresh concrete, superplasticizer brought polar anionic active group such as a SO 3 a, a first-class COO by ionic bonding, covalent bonds, hydrogen bonds and van der Waals interactions, etc. contacts tightly adsorbed on the surface of cement particles strongly polar Yunnan polycarboxylate liquor, so that charged particles of cement, according to the principle of charges repel each other, preventing the adjacent cement particles close to each other, increasing the cement and water area, fully hydrated cement, and in the process of particle dispersion in cement, aggregates release contains free water, improved workability, reduced water mix. At the same time the structure of the side chain having a hydrophilic polyether polycarboxylate liquor, stretching in an aqueous solution, thus hydrophilic perspective a certain thickness of the adsorbed layer of cement particles adsorbed on the surface is formed; when the cement particles near the adsorption layer start to overlap ,, which produce steric hindrance between the cement particles overlap, the greater steric repulsion between cement particles hinder the cohesive effect of the greater, making good concrete slump. GQ-213 non-shrink grout Executive Standard: JC / T986-2005 GQ-212 non-shrink grout is pore filling high-strength steel beams prestressed concrete members and the development of new products, is a composite with a highly dispersed chemical additive made A new material polycarboxylic acid liquor manufacturers, have also been widely used in large-scale equipment and the equipment is installed, a large area of ??ground leveling, emergency repair road surface, airport runway fast Buxiu, plugging the tunnel, foundation grouting works. ◎ The main technical performance: ◆ mobility, this grout in the case of low water-cement ratio, obtained great fluidity, 30 minutes liquidity may remain substantially unchanged. ◆ has a micro-expansion effect, filling the site no shrinkage, to ensure a seamless bond at, not loose. ◆ ease of construction, only at the site of the grout mixing water directly. ◆ The compound contained in the mobility component steel corrosion, prevents corrosion of prestressing steel to improve its durability.
