石油圈中國石化新聞網訊 據世界石油美國新澤西州12月23日消息，為了滿足土工膜制造商和安裝商對線性低密度聚乙烯（LLDPE）日益增長的需求，EPT宣布了一種具有這些特定性能的線增強LLDPE織物。與高密度聚乙烯（HDPE）相比，LLDPE具有優越的柔韌性和更好的平整度，因此需求日益增長。EPT 公司特別配制了LLDPE織物，具有較高的耐化學性和抗紫外線性能，并為該材料提供了抗穿刺和抗撕裂的纖維增強絲束材料。它非常適用于固體和危險廢物填埋場、C＆D垃圾填埋場、采礦和工業及市政給排水等領域。這種材料是黑色的，雙面磨砂處理，寬度可達10英尺，有30、36和45毫米，便于高效制造。獨特的，浮雕紋理處理改善摩擦力將在明年年初試試用所有厚度。 工程聚合物技術公司總裁Mike Satz表示：“我們的客戶對LLDPE的興趣越來越大。我們很高興推出高質量的LLDPE復合膜，它結合了要求苛刻的土工膜應用所需的柔韌性、化學特性、穿刺和撕裂強度。我們相信這種LLDPE薄膜將增強成功的美國生產聚合物纖維和薄膜的產品組合，并滿足制造商和安裝商的要求?！?HDPE和LLDPE都是聚烯烴，具有優異的耐化學性，這使其成為初級和次級密封的常用選擇。然而，與HDPE不同，LLDPE 具有足夠的柔韌性，可以在受控條件下在干燥的地板上提前進行制造、焊接和測試。該工藝包括焊接速度快、焊接一致性好、剝離附著力大、粘結焊縫厚度大、施工質量保證(CQA)費用低等優點。 【注】LLDPE是線性低密度聚乙烯 曹海斌 摘譯自 世界石油 原文如下： Engineered Polymer Technologies has introduced new string-reinforced LLDPE To meet the growing demand for Linear Low Density Polyethylene (LLDPE) bygeomembrane fabricators and installers, EPT has announced a string-reinforced LLDPE fabric with the specific properties required for these types of applications. LLDPE has been in increasingdemand due to its superior flexibility and better layflat versus High Density Polyethylene (HDPE). EPT has specially formulated its LLDPE fabric for high resistance to chemicals and UV, and offers the material with a puncture- and tear-resistant string-reinforced scrim. It is ideal for use in solid and hazardous waste landfills, C & D landfills, mining and industrial and municipal water and wastewater treatment. The material, sold in jet black with a matte finish on both sides is available in widths up to 10 feet, in 30, 36 and 45 mil, for easy and efficient fabrication. A unique, embossed textured finish for improved traction will be available early next year in all thicknesses. “There has been increasing interest in LLDPE from our customers. We are excited to introduce a high quality LLDPE composite membrane that combines the flexibility, chemical properties, puncture and tear strength needed for demanding geomembrane applications,” stated Mike Satz, president of Engineered Polymer Technologies (EPT). “We are confident this LLDPE membrane will strengthen our portfolio of successful US made polymer fabrics and films, and meet the requirements of fabricators and installers,” added Satz. Both HDPE and LLDPE are polyolefins, and have excellent chemical resistance properties, making them common choices for both primary and secondary containment. However, unlike HDPE, LLDPE is flexible enough to be fabricated ahead of time, welded and tested on a dry floor under controlled conditions. The advantages of this process include accelerated and more consistent welding, greater peel adhesion and bonded seam sheer values, and reduced construction quality assurance (CQA) expenses. ?
