Powder polycarboxylate superplasticizer than liquid superplasticizer advantage

  Polycarboxylate superplasticizerIs the third generation of water reducing agent, is an environmentally friendly water reducing agent, the earliest polycarboxylate water reducing agent is liquid, the concentration is also different, with customer demand and market development, powder polycarboxylate water reducing agent came into being, the following to introduce the liquid water reducing agent and powder water reducing agent compared to what are the differences:
Most of the liquid polycarboxylate superplasticizer is 60% water and 40% active ingredient, which is a common product form in the market. In addition, polycarboxylic acid mother liquor is also a common type of product in the market. It is directly synthesized without adding retarding ingredients (such as sugar) or other non-functional polycarboxylic acids (Some polycarboxylic acids have good water reducing performance. Some polycarboxylic acids do not have good water reducing performance at first, but they do have good slump protection). Different concentrations of water reducing agent mother liquor, in principle, because of their different polymerization methods, so the product concentration is different. With the development of powder water reducing agent in the market, the disadvantage of liquid water reducing agent in transportation and storage is also increasing.Obviously.
Polycarboxylate superplasticizer is the third generation of concrete water reducing agent, its comprehensive performance index is excellent, green pollution-free, is a high-performance environmental protection products. It is a kind of powder modified polycarboxylic acid superplasticizer made by spray drying process. Excellent fluidity of the powder, especially suitable for powder building materials requiring high performanceIt is used as a dispersant. This kind of water reducing agent has good dispersibility, high water reducing rate and good adaptability to different cements. When used in concrete and mortar, the fluidity of the mixture is excellent. At the same time can also be used in self leveling floor, grouting material and other projects.
