Membrane?Structure （二） The Fabrication of membrane unit 膜单元的制作 The process of producing membrane member includes cutting diaphragm, connecting the membrane materials and so on.? 膜单元的加工过程主要包括裁剪膜片、膜材连接等。 1. Cutting Diaphragm 裁剪膜片 Cutting Diaphragm is divided into manual cutting and automatic cutting by the cutting machine.? 裁剪膜片分为手工裁剪和裁剪设备自动裁剪。 Automatic cutting by the cutting machine 裁剪设备自动裁剪 6.5.1 Fabrication of membrane structure 膜结构的制作 Membrane?Structure 2. Membrane Connection 膜材连接 热合焊接(Welding) ：Ensure the strength and water tightness? 可保证强度和水密性。 缝合连接(Seaming )： Use industrial sewing machines to produce the materials, which results in the discontinuity of load distribution, stress concentration, easier tearing as well as poor water tightness?. 采用工业缝纫机缝制，膜受力不连续，应力集中，易撕裂，且无法保证水密性。 黏结连接(Warping )：Use special glue or adhesive bonding to connect. This method is commonly used in the repairing and reinstallation of membrane materials.? 由特殊胶水、胶粘剂粘合而成，常用于膜现场修补、二次膜安装。 Ways of Membrane Connection 膜材连接有多种方式，常用的有: Membrane?Structure 6.5.2 Installation of membrane structur
