Variable Speed Refining of Recycled Paper Fibers

这项小企业创新研究第一阶段的提案是针对纸浆和造纸工业的。再生纸纤维的使用正在迅速增长，但由二次纤维制成的纸浆的性能差异很大。这个项目通过控制精炼过程来解决这个问题。随着新材料的加入，混合二次纸废弃物不断发生变化，因此需要一种在线控制策略。该程序将提供有关加工与财产关系的关键信息，并将为精炼过程的在线修改生成控制算法。该项目的其他目标是确定合适的传感器技术来提供过程数据，以及确定可以在潜在的恶劣条件下运行的设备。研究将集中在实验数据上，这些数据将建立精炼条件和所得二次纸浆的过程和性能关系。回收纸浆将在处理前和处理后，以单一或再循环的方式通过精炼厂评估许多特性。预期的结果是，该工艺可以实时控制二次纸浆的性能。将开发设备控制算法，以帮助二次纸浆工业提高二次纸浆的强度和稠度。

This Small Business Innovative Research Phase I proposal is directed at the pulp and paper industry. The use of recycled paper fibers is growing rapidly, yet the properties of the pulp created from secondary fibers varies greatly. This project addresses the problem by control of the refining process. Since mixed secondary paper waste changes continuously as new material is fed into the process stream, an on-line control strategy is needed. This program will provide critical information on processing versus property relationship and will produce a control algorithm for the on-line modification of the refining process. Other objectives of the project are the identification of suitable sensor technology to provide process data, and the identification of equipment that can operate under the potentially harsh conditions. The research will focus on experimental data that will establish the process and property relationship of the refining conditions and the resultant secondary paper pulps. Recycled pulp will be evaluated for numerous properties both prior to and following treatment, in either single or recirculated mode through the refiner. Anticipated results are that the properties of secondary paper pulp can be controlled in real-time by the proposed process. Equipment control algorithms will be developed that can aid the secondary paper pulp industry in improving the strength and consistency of secondary paper fiber pulps.
