Engineering Research Equipment: Emulsion Polymerization>>>>>Process Control Facility>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>

乳液聚合在工业上被广泛应用于生产乳胶漆、粘合剂、涂料、纸张和纺织产品的粘合剂、合成橡胶等应用。生产的乳胶阶段凝结成大块聚合物，或最终产品，经过适当的处理后，以其原始乳胶形式（例如，丙烯酸涂料）可用。此外，环境问题和法规已经引发了一种主要趋势，即远离高溶剂含量的涂料产品，导致水性涂料的广泛使用。乳液聚合反应器的控制仍然是一个难题。控制乳液聚合过程的问题是由于其多相性质，这一点尚不清楚。新兴的传感器技术与建模和过程控制的进步相结合，引入了更好地控制此类工业系统的潜力，并为美国工业提供了乳液聚合的竞争优势。这笔拨款仅用于设备，用于乳液聚合的原型过程控制设施。包括一个完全仪器化的聚合物反应器和自动传感器和控制设备。将进行不同控制策略的各种工艺设计和实验测试，包括新型在线传感器的测试。

Emulsion polymerization is widely used in industry to produce latices for applications such as latex paints, adhesives, coatings, binders in paper and textile products, synthetic rubber, etc. The latex stage of the production is coagulated to give bulk polymer, or a final product, which after suitable treatment is made available in its original latex form ( for example, acrylic paints). In addition, environmental concerns and regulations have initiated a major trend driving away from paint products with high solvent content leading to widespread use of water based latices. The control of emulsion polymerization reactors is still a difficult task. The problems of controlling emulsion polymerization processes are due to their multiphase nature which is not well understood. Newly emerging sensor technology combined with advances in modeling and process control, introduce the potential to better control such industrial systems and provide US industries with a competitive edge in emulsion polymerization. This grant is for equipment only a prototype process control facility for emulsion polymerization. Included are a fully instrumented polymer reactor and automatic sensor and control equipment. Various process design and experimental testing of different control strategies will be carried out including the testing of new on-line sensors.
