济南停车棚:停车棚膜结构材料有哪些?

来源://www.shmtd.com/ 日期:2024-08-26 发布人:

  一、聚酯纤维覆聚氯乙烯(PVC)材料

  特点:

  Strength is low, elasticity is large, easy to age, creep is large, and self-cleaning property is poor.(强度低、弹性大、易老化、徐变大、自洁性差。)

  The price is cheap, it is easy to process and manufacture, the color is rich, and the folding resistance is good.(便宜,容易加工制作,色彩丰富,抗折叠性能好。)

  改进措施及寿命:在表面涂一层聚四氟乙烯涂层,可提高抗老化和自洁能力,其寿命可达到 15 年左右。The surface can be coated with a layer of polytetrafluoroethylene coating to improve its anti-aging and self-cleaning ability, and its service life can reach about 15 years.

  二、玻璃纤维覆聚四氟乙烯(Teflon)材料

  特点:

  High strength, large elastic modulus, self-cleaning, durable and fire-resistant.(强度高、弹性模量大、自洁、耐久耐火等性能好。)

  缺点及适用范围:较贵,不易折叠,对膜结构车棚裁剪制作精度要求较高,寿命一般在 30 年以上,适用于建筑。It is expensive, not easy to fold, and has high requirements for the cutting and manufacturing accuracy of membrane structure carports. The service life is generally more than 30 years and is suitable for permanent buildings.

  三、PVDF 建筑膜材料(聚酯纤维编织基布涂上 PVC 底层再涂 PVDF 树脂形成的复合材料)

  使用情况:该膜结构车棚膜材在我国现有的膜结构建筑上已广泛使用,目前的发展趋势是逐渐被 PTFE 建筑膜材所取代。This membrane structure carport membrane material has been widely used in existing membrane structure buildings in my country. The current development trend is to be gradually replaced by PTFE building membrane materials.

  与 PTFE 对比:强度及防火性与 PTFE 相比具有一定差距,PVC 膜材料的使用年限一般在 10 到 20 年。自洁性和耐久性均不如 PTFE 建筑膜材。Compared with PTFE, there is a certain gap in strength and fire resistance. The service life of PVC membrane materials is generally 10 to 20 years. The self-cleaning property and durability are not as good as PTFE building membrane materials.

  四、PTFE 膜材料

  织物基材及要求:The fabric base material is glass fiber. The diameter range of the fiber should be within 3.30~4.05μm, and the weight should be greater than 150g/m.(织物基材为玻璃纤维,纤维的直径范围应在 3.30~4.05μm 范围内,重量应大于 150g/m。)

  涂层主要材料及含量、重量要求:The main material of the coating should be polytetrafluoroethylene resin, the content should not be less than 90%, and the weight of the coating should be greater than 400g/m.(涂层的主要材料应为聚四氟乙烯树脂,含量应不低于 90%,涂层的重量在应大于 400g/m。)

  厚度要求:The thickness of PTFE membrane material should be greater than 0.5mm.(PTFE 膜材料的厚度宜大于 0.5mm。)

  性能:能防止化学腐蚀和紫外线侵蚀,不易老化,在雨水中具有自洁性能。It can prevent chemical corrosion and ultraviolet erosion, is not easy to age, and has self-cleaning properties in rainwater.
