研究了玻璃微珠填充超高分子量聚乙烯（ＵＨＭＷＰＥ）基复合材料的润湿及土壤粘附特性，分析了玻璃微珠的掺量、粒径与复合材料表面润湿性、土壤粘附特性的关系。试验结果表明：随着玻璃微珠掺量的增加，水对复合材料表面的接触角减小，土壤在复合材料表面的粘附力增大；当玻璃微珠的体积含量不超过９％时，玻璃微珠的加入不至于明显地降低ＵＨＭＷＰＥ的减粘降阻特性。由于“非光滑效应”，水膜在表面曳力的作用下力图拉离ＵＨＭＷＰＥ基体表面，土壤／基体间产生楔开应力，使土壤易于脱离基体表面。
The wetting and soil adhesion properties of UHMWPE-based composites filled with glass micro-beads were investigated. The effects of the content of micro-beads, the particle size, wettability of composite surface and soil adhesion properties relationship. The experimental results show that with the increase of glass microbead, the contact angle of water to the composite surface decreases and the adhesion of soil to the composite surface increases. When the volume content of glass microbeads does not exceed 9% The addition of glass beads does not significantly reduce the viscosity reduction of UHMWPE drop resistance characteristics. Due to the “non-smooth effect”, the water film tries to pull away from the surface of the UHMWPE substrate under the action of the surface drag, and the wedge-opening stress is generated between the soil / substrate so that the soil can be easily detached from the surface of the substrate.
