| 中文摘要: |
| 橡胶挤出扩胀法，是一种新的橡胶加工方法，适宜于宽幅橡胶薄片材料的生产。该法使用的挤出机，具有机头结构简单、价廉、占地面积小，挤出物质量好等优点。对三组不同结构的扩胀机头进行试验，结果得出：橡胶挤出扩胀方法的适宜扩胀比为2.0～2.5；在挤出扩胀过程中对胶片施加纵向牵引力比横向牵引力好。 |
| 英文摘要: |
| The rubber blowing extrusion is a new rubber process.It is useful for the production of wide and thin rubber sheets.The extruder used for this process features simple head structure，low price，less space and quality extrudate.The experiment is carried out on 3 types of extruder heads with different structures.The result shows that the appropriate blowing ratio of the extrudate is 2.0～2.5；the stretch applied on the sheet is in the longitudinal direction better than in the lateral direction during the blowing extrusion. |
