Product Description
RDP (Redispersible Polymer Powder/Rdp Powder) or VAE Powder (Vinyl Acetate Ethylene Copolymer)Redispersible Polymer Powder(Redispersible Latex Powder Redispersible Polymer Emulsion Powder) plays an important role as an additive of building mortar. Adding redispersible emulsion powder to mortar can prepare a variety of mortar products such as tile glue, insulation mortar, self-leveling mortar, putty, plastering mortar, decorative mortar, joint pointing agent, repairing mortar and waterproof sealing material, which expands the application range and application performance of building mortar. Of course, redispersible emulsion powder has adaptability problems with cement, admixtures and admixtures, which should be paid enough attention in specific applications.
The polymer rdp/Redispersible Polymer Powder(redispersible emulsion powder) is physically mixed with other inorganic adhesives (such as cement, hydrated lime, gypsum, clay, etc.) as well as various aggregates, fillers and other additives (such as hydroxypropyl methyl cellulose, polypolysaccharide (starch ether), cellulose fiber, etc.) to make dry mix mortar. When the dry powder mortar is mixed in water, under the action of hydrophilic protective colloid and mechanical shear force, the latex powder particles can be quickly dispersed into water, and enough to make the redispersible latex powder fully film. The different composition of rubber powder has an impact on the rheological properties of mortar and various construction properties: the affinity of latex powder to water when it is redispersed, the different viscosity of latex powder after dispersion, the impact on the gas content of mortar and the distribution of bubbles, the interaction between rubber powder and other additives, so that different latex powder has an effect of increasing fluidity, increasing thixotropy and increasing viscosity.Rdp/Redispersible emulsion powder can be physically mixed with other mechanical adhesives (such as cement, hydrated lime, gypsum, etc.) as well as various aggregates, fillers and other additives (such as cellulose, starch ether, lignocellulose, hydrophobic agents, etc.) to make dry mixed mortar. When the dry mortar is mixed in water, the latex powder particles are dispersed into the water under the action of hydrophilic protective colloid and mechanical shear. For example, in the dry shotcrete repair mortar, the dry mortar with the redispersible emulsion powder and water are mixed at the end of the nozzle for about 0.1s and then sprayed onto the construction surface, which is sufficient for the redispersible emulsion powder to fully disperse and form a film. In the early mixing stage, the emulsion powder has begun to affect the rheology and constructability of the mortar. Due to the different characteristics of the emulsion powder itself and the modification, this effect is also different, some help the flow effect, and some increase the thixotropy effect. The mechanism of its influence comes from many aspects, including the influence of the affinity of the emulsion powder to water when dispersed, the influence of the different education of the emulsion powder after dispersion, the influence of the protective colloid, the influence of the cement and water, the influence of the gas content of the mortar and the influence of the bubble distribution, and the influence of its own additives and the interaction with other additives. Among them, the more common view is that the redispersible emulsion powder usually increases the gas content of the mortar, thus playing a lubricating role in the construction of the mortar, and the emulsion powder, especially when the protective colloid is dispersed, the increase in the affinity for water and the teaching consistency helps to improve the cohesion of the construction mortar, thereby improving the workability of the mortar. Subsequently, wet mortar containing emulsion powder dispersion is constructed on the working surface. With the reduction of water at three levels, the absorption of the base, the consumption of cement hydration reaction, and the evaporation of surface water into the air, the resin particles gradually approach and the interface gradually fuse with each other, and finally become a continuous polymer film. This process mainly occurs in the pores of the mortar and the surface of the solid.Technical data | Technical Date | HEARST RD 503M | HEARST RD 760F | HEARST RD 740H | HEARST RD 745W |
