Lining bulk storage equipment with sheets of ultra-high- molecular-weight polyethylene [UHMW-PE] is, in many instances, an ideal way to improve the flow of bulk solids. The benefits offered by UHMW-PE are becoming more widely recognized and accepted throughout the world. However, further education on the proper use of UHMW-PE is necessary. The technical information needed to predetermine the effectiveness of a liner is seldom sought out; in addition, liners are often installed incorrectly.
This article covers the key physical properties of UHMW-PE and how they help solve some bulk solids flow problems. The article also discusses proper installation methods and how they directly relate to the success or failure of the liner.
