Dry mortar, is one of the emerging field of building materials dry mixed materials, according to the Guangdong Provincial standard definition of "dry mortar application of technical regulations DBJ / T 15-36-2004" as: dry mortar manufacturer specializing in the production by means of to cement the main binder and dry screening process fine aggregate, mineral admixtures, reinforcing materials and additives blended mixture made by a certain percentage. Cement is a very hard, brittle, flexible material with poor, many of the construction of modern buildings, must be modified with a polymer mortar dry mortar, in order to meet the construction requirements. In the 1930s, people began to use two-component system, a two-component system is prone to many problems Wuhan dry mortar brand, the main content is difficult to accurately control the polymer emulsion. The reason for the error has inexperience and lack of training for workers, or cut corners to save costs. In addition to the two-component system is difficult to use, the additional cost increases and increased the difficulty of the material flow is also one of the reasons. 1953 German WCAKER CHEMIE invented redispersible powder dry mortar wholesale Wuhan, which makes the production of polymer-modified dry mortar as possible, now known as the single-component systems. Redispersible powder is made by spray drying an aqueous emulsion of a special, mainly based on vinyl acetate - ethylene copolymer prepared out of the polymer binder. This powder is mixed with an organic binder in water or dispersed dry mortar factory in Wuhan, can be restored to their original state of an aqueous emulsion, and keep the machine adhesive has the typical features and functionality, it is called re-dispersible powder . After partial evaporation of the water, the polymer particles by coalescence, forming a layer of polymer film, play a role in the adhesive. Depending on the ratio, the use of re-dispersible polymer powder dry mortar modification, can improve a variety of substrates with glue bonding strength and improve flexibility and mortar deformability, engage in bending strength, wear resistance toughness, bond strength and density and water retention capacity and workability.
