A Study of Filtration of Papermaking Suspensions with Application to Papermaking

乔治·蔡斯CTS-9410275建议研究滤水和微粒留着的过滤过程，特别是与造纸机湿部操作有关的过滤过程。将模拟滤饼过滤和颗粒在深床中的滞留，并通过实验获得材料系数。湿纸浆的变形行为作为施加压力、流速和纸浆性能的函数将在实验室中确定。用切片法、电子显微镜和重量法测定微粒的保留率。该项目将由俄亥俄州阿克伦阿克伦大学的G.G.Chase和纽约州立大学锡拉丘兹帝国纸业研究所的B.V.Ramarao合作完成。费用分摊由这两个机构提供。如果成功，所建立的滤饼信息预测模型将用于评估动态条件下的过滤过程，并在造纸机和其他制造过程中得到具体应用。***

ABSTRACT George Chase CTS-9410275 It is proposed to investigate the filtration processes of water drainage and fine particle retention, with special relevance to the operation of the wet-end of paper machines. Cake filtration and particle retention in deep beds will be simulated, and the material coefficients will be obtained from experiments. The deformation behavior of wet pulp mates as a function of the applied pressure, flow rate and pulp properties will be determined in laboratory. The fine particle retention will be measured by sectioning, electron microscopy, and gravimetric method. This project will be performed by collaboration between G. G. Chase of Akron University, Akron, OH, and B. V. Ramarao of SUNY, Empire State Paper Research Institute, Syracuse, NY. Cost sharing is provided by both institutions. If successful, the resulted predictive model for cake information will be used to evaluate filtration processes under dynamic conditions, with particular application in the paper making machine and other manufacturing processes. ***
