Redispersible polymer powders are polymer emulsions which have been converted by a series of process such as high temperatures and pressures, spray drying and surface treatment to powdered thermoplastic resin materials. When mixed with water, these powdered organic binders can redisperse in water back into new emulsions with essentially identical properties to the original copolymer.. read more →

The production of redispersible polymer powder is mainly divided into two steps, namely, emulsion polymerization and drying, as shown in the figure. (l) Emulsion Polymerization Monomers adopted for emulsion polymerization determine the types of redispersible polymer powder. Polymer monomers used for the production of redispersible polymer powder are mainly olefins and unsaturated monomers, including a.. read more →

The traditional method of pasting tiles or stone is to adopt the on-site preparation, mixing cement, sand, 108 glue and water according to a certain proportion and then pasting. Since the water retention of mortar of this kind is low, tiles should be soaked and wetted in water beforehand, and then put mortar onto the.. read more →

①. It has good water retention. Tiles do not need soaking treatment before pasting, can be used in construction for a longer time and smeared in large area; it has good adhesion effects, strong vertical flow resistance, and the construction can be from top to bottom.   ②. Since it has good workability, slide resistance,.. read more →

The building gypsum is the main raw material that guarantees the bond strength of adhesive plaster, and should meet the requirements of national standard GB / T 9776-2008.   As for the setting time of building gypsum, the standard requires that the initial setting be greater than 6min and that the final setting be less.. read more →
