| | This article analyses theoretically the technical feasibility of processing raime/cotton blended yarn with A591 cotton type OE spinning frame, introduces the process, technology and final quality of the 58 tex yarn by combing cotton and raime noil, and records the problems and their tackling during trials on the OE spinning frame. Beijing No.3 Cotton mill, after improving the OE spinning frame, has produced a great deal of 58 tex yaren of raime/cotton blends, whose uniformity is obviously better and end bre... | | 文章从理论方面分析了A591棉型气流纺纱机纺制麻棉混纺纱的可行性;介绍了用精梳落(苧)麻与棉混纺58号纱的工艺流程、工艺设计和成纱质量,以及试纺中在气流纺纱机出现的问题和解决方法。北京第三棉纺织厂通过将上述气流纺纱机适当改进后,纺出的58号麻棉气流纱的条干显著地优于环锭纱,因而织机断头率大幅度下降,该厂现已大批量进行生产。 | | 文摘来源 | | Abstract It introduces several kinds of CO [edit1][edit2]shift processes in large-scale ammonia plants,viz,Linde Sulphur-resistant shift processin three stages at 8. 24MPa,France t. p sulphur-resistant shift process in two stages at 8. 23MPa,Uhde sulphur-resistant shift-process in two stages at 6.45MPa,Lurgi sulphur-resistant shift process in two stages at 5. 25MPa. The design parameters of these processes and the heating and reduction differencess of the catalysts are copmared. | | 介绍了国外几个大型CO变换工艺。林德的8.24MPa耐硫三段变换流程,法国t·p的8.23MPa耐硫二段变换流程,伍德的6.45MPa耐硫二段变换流程,鲁奇的5.25MPa不耐硫二段变换流程。并比较了这几种流程的工艺设计参数以及触媒升温还原的差异。供设计合成氨流程参考。 | | 文摘来源 | | The source of the assembly process flow data and the application and transformation of these data in the assembly flow process design for advanced Boeing airplane manufacture are described. The ideas and methods for dividing the process flow nodes in assembly process flow of Boeing airplane are given. The basic position of the single source of product data in aircraft manufacturing is emphasized. | | 论述了在先进的波音飞机制造业中装配工艺流程数据的来源以及这些数据在装配流程工艺设计过程中的应用和转化,同时给出了波音飞机装配工艺流程中流程结点的划分思路和方法,强调了单一产品数据源在飞机制造中的基础地位。 | | 文摘来源 | |   | | << 更多相关文摘 |
