| 摘 要： | 衬层涂覆工艺是流体的一种成型加工过程,涂覆的工艺性能与衬层浆料的流变性密切相关。经对发动机涂覆过程的分析和研究,手工涂刷的工艺性能应包括易刷性、抗垂挂性和流平性,可分别用涂刷力、屈服值和流平时间表征。通过对一种具有很好涂刷性的实验衬层浆料的流变特性测定,研究了涂覆工艺性能与衬层浆料流变性的关系。结果表明实际涂刷工艺性能与理论分析十分吻合。从而探索了一条经流变分析来预估、判断和控制发动机衬层涂覆工艺性能的技术途径。

| Abstract: | The coating technology of liner on a rocket motor is a model-covering process and the processing properties are closely related with the rheological behavior of liner slurry.By means of analyzing the coating course of motor liner, it is suggested that the swabbing technology which should deal with swabability,sagging-restricting and flow level can be described by swabbing force,yield value and flow level time,respectively.The experimental results showed that the relation between the practical swabbing behavior and the rheological properties of a liner slurry are in good agreement with the theoretical analysis.As a result, the way to it is pointed predict,evaluate and control the coating characteristics of rocket motor liner by the aid of the testing rheological parameters of liner slurry was suggested. |
