膜结构车棚膜布膜材用国产还是进口的好？

膜结构车棚膜布膜材用***产还是进口的***？

Is the film material of film structure shed made in China or imported good?

建筑膜材俗称（膜布）作为膜结构建筑中的重要组成部分，膜材的质量直接决定了整个膜结构建筑项目的机械强度以及使用寿命，现在市面上建筑膜材种类繁多，品牌林立，质量参差不齐，加之膜材加工过程中也没有相应的统一标准，那么膜结构制作过程中如何保证膜材质量呢？

As an important part of membrane structure construction, the quality of membrane material directly determines the mechanical strength and service life of the whole membrane structure construction project. Now there are many kinds of construction membrane materials on the market, with numerous brands and uneven quality. In addition, there is no corresponding unified standard in the processing process of membrane materials, so how to ensure the quality of membrane structure in the production process What about the quality of membrane materials?

如今市场上的膜材主要分为进口与***产两***类，价格差异还是比较***的，就拿我们常用的PVDF膜材来说，进口的比***产的平均价格高60-70元以上，膜材的选择上我们推荐使用知名的老品牌，进口的如：杜肯、海德斯、米乐、德***赛德乐、法拉利，***产的如：浙江星益达、锦达、宁波汇聚、上海篷邦、湖北金龙等，进口与***产膜材的主要差异在自洁性以及质保年限上，进口膜材质保一般在15年左右，***产在10-15年左右，所以在选择膜材的时候要根据工程的具体情况，对使用年限、强度、跨度、张拉力等有一定要求的建筑结构上我们推荐使用进口膜材，避免后续的维护和减少未来十年后更换的费用；然而对于车棚之类的小跨度雨棚我们推荐使用性价比更高的***产膜材。

Nowadays, the membrane materials in the market are mainly divided into two categories: imported and domestic. The price difference is relatively large. For PVDF membrane materials commonly used by us, the average price of imported membrane materials is more than 60-70 yuan higher than that of domestic ones. We recommend the use of well-known old brands in the selection of membrane materials, such as: Duken, heides, Milo, German sideler, Ferrari, and domestic ones like: Zhejiang Xingyi The main differences between imported and domestic membrane materials are self-cleaning and warranty period. The warranty period of imported membrane materials is generally about 15 years, and that of domestic membrane materials is about 10-15 years. Therefore, when selecting membrane materials, we should consider the construction structure with certain requirements for service life, strength, span, tension and so on according to the specific conditions of the project We recommend the use of imported membrane materials to avoid subsequent maintenance and reduce the cost of replacement in the next ten years; however, for small span canopy such as car shed, we recommend the use of domestic membrane materials with higher cost performance.
