Read MoreRedispersible polymer powder features and applications in dry mix mortar
Read MoreRedispersible polymer powder can improve the bending strength and adhesion strength of the mortar because it can form a polymer film on the surface of the mortar particles, and there are pores on part of the surface of the film, and the pore surface is filled with the mortar,
Read MoreRedispersible polymer powder(RDP) and other inorganic adhesives (such as cement, slaked lime, gypsum, clay, etc.) and various aggregates, fillers and other additives (such as hydroxypropyl methyl cellulose, starch ether, cellulose fiber, etc.) After physical mixing, dry-mix mortar is made.
Read MoreRDP has extremely outstanding bonding strength, improve the flexibility of mortar and have a long opening time, give the mortar excellent alkaline resistance, improve the mortar adhesion, flexural strength, water resistance, plasticity, wear resistance and construction, in the flexible anti-crack mortar more has a strong flexibility.
Read MoreTest method for properties and viscosity of redispersible polymer powder RDP ,Worldwide are widely used to disperse polymer powder RDP with vinyl acetate and ethylene copolymerized emulsion powder, ethylene and vinyl chloride and lauric acid vinyl ester ternary copolymer powder,
Read MoreOne of the most important applications of polymer-modified cement mortar is the application of thin-layer construction methods to tile. The specific process is as follows: the dry powder adhesive with the package is mixed with water on the spot,
Read MoreRedispersible polymer powder produced by spray-drying special water-based emulsion, mostly based on vinyl acetate-ethylene (VAE), and then obtained a free flowing organic polymer powder. It can re-disperse in water, and form a film after water evaporation by coalescence of individual polymer particles.
Read MoreMFFT is the lowest temperature which allows polymer particles in emulsion have enough activity for intercoagulation and continuous film forming. During films forming, the polymer particles have a closer arrangement. To form a continuous film, besides good dispersion emulsion, there is also the requirement of polymer particles deforming (which shows the pressure between particles forced by hydraulic pressure). Closer the particles be, stronger the pressure would become.
