可释放负离子的人造聚乙烯草丝纤维研究

Study on Artificial PE Grass Fiber Releasing Negative Ions

制备了可释放负离子的人造聚乙烯(PE)草丝纤维,并研究了其特性。结果发现,增加负离子粉的添加量以及采用具有更高负离子释放率的负离子粉,可以提高人造PE草丝纤维的负离子释放能力;随着压力的增加,人造PE草丝纤维的负离子释放量降低;而随着温度与压力变化频率的提高,人造PE草丝纤维的负离子释放量也提高;铺设有负离子人造草坪的区域,在垂直距离上随高度的增加空气中的负离子含量下降。

Polyethylene（PE） grass fiber releasing negative ion was prepared, and its properties were studied. The results show that the ability of releasing negative ions can be improved when the addition content increases or the releasing rate of negative ions increases. Its releasing ability also can be increased at higher changing frequency of temperature and pressure. Negative ions content in air decreases with the increasing of the height on the vertical distance.
