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.

纯粹的聚合物凝胶力学强度相对较低，而新型多功能复合凝胶的力学强度相对较高，能有效的解决井下地层漏失。

The pure polymer gel has low mechanical strength, but the new multi-function composite gel has high mechanical strength, which can control the down-hole loss circulation effectively.
