| 聚乙烯丙纶复合防水卷材的选材及结构特点，使其具有抗渗能力强、抗拉强度高、低温柔性好、线胀系数小、易粘接、摩擦系数大、稳定性好、无毒、变形适应能力强、适应温度范围宽、使用寿命长等良好的综合技术性能。聚乙烯、聚丙烯（丙纶）均耐化学稳定、耐腐蚀霉变、耐臭氧，而丙纶具有良好的力学性能。完全隔绝紫外光条件下，聚乙烯、聚丙烯已证明的寿命大于50年。 The material selection and structural characteristics of polyethylene polypropylene composite waterproof roll make it have good comprehensive technical properties, such as strong impermeability, high tensile strength, good low temperature flexibility, small linear expansion coefficient, easy adhesion, large friction coefficient, good stability, non-toxic, strong deformation adaptability, wide temperature range, long service life, etc. Polyethylene and polypropylene (PP) are resistant to chemical stability, corrosion and mildew, and ozone, while PP has good mechanical properties. The life of polyethylene and polypropylene is more than 50 years. |
