Concrete reinforcement agent - sodium polyacrylate
DETAILS
Sodium polyacrylate is a polymer compound with hydrophilic groups obtained by neutralization of acrylic acid and sodium hydroxide, and polymerization with an appropriate amount of oxidation-reduction agent. It is a white powder, odorless and tasteless. Slowly dissolve in water to form an extremely viscous transparent solution. Product indicators project index exterior White powder Free alkali qualified Sulfate (calculated as SO4) ≤0.5% Dry weight loss ≤10% Burning residue ≤76% Heavy metals (measured in Pb) ≤0.002% Arsenic (calculated as As2O3) ≤0.0002% Residual monomers ≤1% Oligomers ≤5% The role of sodium polyacrylate in concrete: (1) The thickener component used as a high-efficiency water reducing agent in the preparation of high-strength concrete is used to solve the contradiction between the deformation ability and anti segregation property of high flow concrete. (2) As a thickening component of the pumping agent, it is used to ensure that the pumped concrete is not blocked, does not segregate, and has good cohesion, thereby increasing its pumpability. (3) As a thickening component of non separating agent for underwater concrete. Usage: Usage and precautions: Dissolution method: Stir and slowly add sodium polyacrylate powder evenly into normal temperature water (preferably soft water) at 20-50 ℃ (note: do not add a large amount at once, and sprinkle the adhesive powder into weighed warm water instead of pouring water into the adhesive powder, otherwise it will form interlaced gel clusters that are difficult to dissolve). Keep it warm and stir until it dissolves into a uniform solution. The solution concentration is generally around 0.1-0.2%, and the dissolution time is about 0.5 hours. |
