高相对分子质量聚乙烯的增塑熔纺，由于聚合物浓度较高，大分子缠结多，纤维超拉伸比较困难，难以达到高强度。
Plasticized melt - spun HMWPE fiber is hard to draw to high strength because of high HMWPE content and more molecular tangle in as-spun fibers.
因此，具有较大相对分子质量的有机物会妨碍沸石去除氨氮。去除大分子有机物能有效地提高氨氯的去除效果。
Therefore, removal of organics with higher MW could enhance the efficiency of ammonia-nitrogen removal by zeolite, which might otherwise impede the removal.
