土工格栅拉伸机理及工艺研究

Study on Stretch Mechanism and Process Conditions in Drawing Geogrid

探讨了土工格栅拉伸机理;通过实验分析了土工格栅拉伸工艺条件对土工格栅性能的影响。结果表明:在格栅适宜的拉伸温度范围内,较低的拉伸温度、较高的拉伸速度及采用二次拉伸工艺有助于提高土工格栅的性能和生产率。

Stretch mechanism and process conditions in drawing geogrid are discussed in this paper. The results show that lower orientation temperature, higher velocity, and a second drawing process will contribute to improving the property of geogrid.
