In the design of brochures, a brief introduction of the SBR production status, trends, performance and the main purpose of the current SBR ， also introduced the two common industrial polymer production methods， And a comparison, final Determined to low-temperature emulsion polymerization as a polymerization technology production methods. In the design process, in accordance with the requirements of the mission design, a more detailed material balance and energy balance, the equipment was calculated and the selection process, while the production of SBR in the process of attention to safety issues and Three wastes governance made note of the entire device to a simple technical and economic evaluation. Drawing the corresponding design drawings, design drawings, including process maps, plans of major equipment assembly, equipment layout plans.
