1) mechanical roughening
机械打磨
1.
Through simulating the on-the-spot application method,the following factors influencing interlayer adhesion of polyurethane woodenware finish coats were investigated: mechanical or non-mechanical roughening between coats,effective hydroxyl of hydroxyl resin,coating interval time between coats,various n(—NCO)∶n(—OH) ratio,change of surrounding temperature and additives,etc.
通过模拟施工现场的操作方式,考察了影响聚氨酯木器面漆层间附着的因素:涂层间有无机械打磨,羟基树脂的有效用羟基,涂层间涂装间隔时间,n(—NCO)∶n(—OH)不同配比,环境温度的变化以及助剂的使用等,讨论了通过改善施工方式和选择有效用羟基树脂以改善聚氨酯木器面漆涂层间附着的问题。

补充资料：通用机械：波纹管阀
用波纹管作为阀杆密封组件的阀门。它常用于对阀杆密封要求严格的场合﹐如用于高真空的场合和核工业中。采用波纹管代替普通阀门上的填料函或与填料函并用﹐可使阀杆部位无泄漏﹐以防止放射性物质或贵重物质外漏﹐或保持高真空。波纹管随阀杆的升降而伸缩﹐其最高工作压力取决于波纹管的耐压强度和疲劳强度。
