Cement is a very hard, brittle, flexible material with poor, many of the construction of modern buildings, with a polymer mortar must be modified to meet the construction requirements. In the 1930s, people began to use two-component system, a two-component system is prone to many problems, mainly it is difficult to accurately control the content of 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 outside Hang-Fu dry mortar, additional costs and increase the difficulty of the material flow is one of the reasons for the increase. 1953 German WCAKER CHEMIE invented redispersible powder, 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, 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 powders. 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 modified Wuhan dry mortar, can improve the bonding strength of Wuhan BAOYE various substrates dry mortar, mortar and improve flexibility and deformability engage in bending strength, wear resistance, toughness, bond strength and density, and water-holding capacity and workability. As China entered the building a moderately prosperous society in the history of the process, you can expect dry mortar, the next 15 years, China's infrastructure, technological innovation, real estate and other fixed assets investment will remain at a high level during the "Eleventh Five-Year" , China's urban per capita will reach 28 square meters of residential, rural residential per capita reached 33 square meters, increasing the need for new housing around 8 billion square meters. By 2020, the city will reach 35 square meters per capita housing in rural areas will reach 40 square meters, totaling more than 200 one hundred million square meters of new residential, for the development of the construction industry provides a huge market space, but also for the dry-mix mortar industry the development of a huge market base. _ Wuhan Wuhan dry mortar cement (certified) _ dry mortar supplied by Wuhan Hongshan District pavilion cement operation.
