Performance and quality index of synthetic water reducing agent: This product can react with unsaturated acid such as acrylic acid and cis-butylillic anhydride. The polycarboxylic acid-based water reducing agent produced has high cost performance, high water reduction rate, good plasticity and durability. Excellent and so on.
¡¤ High cost performance. In the case of achieving the same water reduction rate, it has a high cost performance.
¡¤ Low dosage and high water reduction rate. The mother liquor containing 20% solids of water reducing agent, the dosage of 1.0% (the amount of cementing material), the water reducing rate can reach 30-35%.
¡¤ Good plasticity. The slump loss was less after 1 h of concrete.
¡¤ Excellent durability. It can greatly reduce water consumption and improve the durability of concrete.
¡¤Green. The environmentally harmful formaldehyde is not used in the production of water reducing agent, and the chloride ion and sulfate content are low.
Application: Polycarboxylate water reducer produced by this product can be used to prepare retarding concrete, precast concrete, cast-in-place concrete, high performance concrete, large fluid concrete, self-compacting concrete and mass concrete. It can be widely used. High-speed railways, large bridges, water conservancy, hydropower, nuclear power, subways, highways, harbor terminals and various construction projects.
Packing specification: The sheet is packed in 20 kg woven bag.
Storage and transportation: This product is non-toxic and non-combustible. It can be handled according to the general chemical transportation regulations. Store in a dry and ventilated place to avoid sunlight and rain. Product shelf life: two years. |
