Le De's membrane treatment content:
Features of Lede waterproof and breathable film: ·Excellent self-cleaning performance ·It can prevent various dust from entering the equipment and maintain a high air flow rate without passing through water, aerosols, and particles. ·Opening rate: above 85%; ·Uniform pore size distribution can be controlled between 0.01 and 5.0 μ Within m ·Has an ultra long service life ·Preferred substrates (polytetrafluoroethylene (ECT FE), non-woven and mesh fabrics, polyester, polypropylene)
Scanning electron microscopy images ranging from 2000 to 10000 times clearly demonstrate the uniformity of the Lede membrane itself, the rigidity of membrane fibers, and the porosity of the membrane, among other aspects. In order to give everyone a more intuitive understanding of our product, please take a look at the microscopic pictures.
In practical production, there are many waterproof and breathable valves that require metal materials to achieve higher strength and longer lifespan. The metal sleeve is equipped with a threaded waterproof and breathable valve, commonly known as a respirator, breathable screw, etc. This product uses the EPTFE membrane material jointly developed by our company and partners. The shell is made of brass, aluminum, or stainless steel, and the membrane and shell are tightly matched with the metal shell through interference fit. It has the characteristics of stable performance, simple installation, longer use time, and high waterproof and breathable performance. Use a socket or ring wrench for installation, and pay attention to controlling the torque between 0.5 and 0.6NM. The specific adjustment depends on the size and hardness of the matching installation thread and O-ring. Good waterproof performance Quickly restore breathability by leaving the liquid surface The groove design ensures that the O-ring will not overflow 储存要求 1、避免阳光直射,避免靠近热源,避免灰尘 2、储存时间不超过1年
操作注意事项 1、把膜片安装位安排在竖立的方向,以免灰尘堆积 2、在安装膜片的位置施加明显的定位线,最有是限位台阶 3、安装表面粗糙度不得超过0.4 µm Ra。 4、确保环境清洁,以免环境灰尘干扰安装效果 5、确保安装面干净、干澡 6、避免有尖刺的部件触碰防水透气膜片 7、请戴干净胶指套或胶手套操作,避免手指直接接触防水透气膜片 8、准备钝边镊子不得使用可能损坏防水透气产品的尖嘴镊子。
从离型材提取膜片 方法1:卷起离型材料,使防水透气膜片与离型材料分离,分离到约1-2mm再用摄子提取膜片 方法2:把产品放在平整上的台面上,用摄子轻轻挑起膜片,挑起1-2mm后摄子轻夹直接从离型材料上轻轻取下膜片
贴放膜片
把膜片准确放置在目标限位区间内 若有二次粘膜片,应把前次膜片废除,先清洁好粘贴区间,重新贴新膜片 放置定位好膜片后,用手指用约3万pa的压强垂直持续施加在膜片上5至10秒钟 为了确保为效粘贴,应采用橡胶辅助压合工具 橡胶辅助工具应与环形背胶吻合 橡胶硬度大约在30度,厚度可以2至5mm 压合压强约3万pa 辅助压合时间大约24小时 ![]()
安装后的检查 1、是否定位好 2、离型材料的废材是否有附在膜片上,若有附上应去除 3、有无灰法、异物,若有应吹除
移除不良膜片 如果生产中或使用中发现有不良情况发生,需移除受损的膜片。可以应用95%医药酒精或白电油进行清除膜片上的背胶。 |
