防渗膜应用在高速公路路基防冻胀翻浆处理
什么是防渗膜?防渗膜有什么特性?防渗膜在东北公路路基的冻胀翻浆的应用方法?泰安市瑞恒土工材料有限公司为你娓娓道来,希望与你共同进步了,呵呵。
防渗土工膜标准名称为聚乙烯土工膜,主要是乳白色半透明至不透明的热塑性树脂材料-聚乙烯树脂制作而成。聚乙烯是高分子聚合物,是、无味、无臭的白色颗粒,熔点约为110℃-130℃,相对密度0.918—0.965;防渗膜具有良好的耐热性和耐寒性。化学稳定性好,具有较高的刚性和韧性,机械强度好,耐环境应力开裂与耐撕裂强度性能好,随着密度的上升,机械性能和阻隔性能会相应提高,耐热,和抗拉强度也更高;可耐酸、碱、有机溶剂等腐蚀。
Impermeable membrane application in Expressway Subgrade Frost Heaving boiling process
What is the film? Impermeable membrane having characteristic? Impermeable membrane in the NortheastHighway Subgrade Frost Heaving application methods? Tai'an Ruiheng geotechnical material limited company for you to explain, hope to make progress together with you, ha ha.
Impermeable geomembrane for polyethylene geomembrane is milky white, translucent to opaquethermoplastic resin material - polyethylene resin produced. Polyethylene is the high polymer, is non-toxic,tasteless, odorless white particles, the melting point of about 110 ℃ -130 ℃, the relative density of 0.918 - 0.965; impervious membrane has good resistance to heat and cold resistance. Good chemical stability, high rigidity and toughness, good mechanical strength, resistance to environmental stress cracking and tearing strength performance is good, as the density increases, the mechanical properties and barrier properties are increased, heat resistant, and the tensile strength is higher; to acid and alkali, organic solvents and othercorrosion.
