Ceramic water reducing agent Top Product

Water reducing agent mainly can make the mud water content is low, the fluidity is good, does not return to the coagulation and has the good stability.

Ceramic water reducing agent, also known as ceramic grinding aids, is widely used in the production of ceramic industry.

Dispersion: cement mixed with water, because the molecular attraction between cement particles, cement slurry to form the flocculent structure, so that 10% to 30% of the mixing water is wrapped in cement particles, can not participate in the free flow and lubrication, thus affecting the fluidity of concrete mixture. When adding water reducing agent, water reducing agent because the molecules can adsorb on the cement particle surface, the surface of the cement particles with the same charge (usually negative charge), the formation of the electrostatic repulsion, the cement particles dispersed, flocculation structure damage, releasing the wrapped portion of the water, in the flow, so as to effectively increase the flow of concrete mixture.

Lubrication: reduction of water in hydrophilic base is very strong, so the superplasticizer adsorption film on the surface of the cement particles can form a layer of stable solvent water film and water molecules, the water layer has good lubrication effect, can effectively reduce the sliding resistance of cement particles, so as to make concrete liquidity to further improve the.

Steric hindrance effect: the structure of water reducing agent with hydrophilic polyether side chain, stretching in aqueous solution, so as to form a certain thickness of the adsorption of the surface of the cement particles in the adsorption layer. When the cement particle close, adsorption layer began to overlap, which produce steric interactions between particles in cement overlap more, the steric repulsion of the greater cohesion between cement particles block is larger, so the slump of concrete good.

Sustained release effect of graft copolymerization of branched chain: new water reducing agent such as poly carboxylic acid water reducing agent in the preparation process, the molecular superplasticizer grafted on some branched chain, the chain can not only provide steric effect, and the hydration of cement with high basicity in the environment, the chain also slowly being cut off to release the polycarboxylic acid is a dispersing agent, which can improve the dispersion of cement particles, and control the slump loss.
