Membrane structure shed

Hot welding is to heat the bonding seam and melt the coating on the upper layer of the fabric, then apply pressure and cool the bonding seam. It can blow hot air to the membrane material to make the membrane material touch the heated object, or it can obtain the corresponding heat through high-frequency electromagnetic waves. Heat and bonding for PVC coated polyester filament fabric and PTFE coated glass fiber fabric. As for PTFE coated glass fiber fabric, because PTFE cannot melt by itself, it is necessary to select a different material in the inner layer. Mechanical bonding of membrane structure shed: although sewing and heat sealing have been widely used in membrane processing workshops, mechanical bonding is also sometimes used. Mechanical bonding usually takes the form of embedding rope at the edge of two diaphragms, and clamping clamping plate at the overlapping position of two diaphragms. The splint request is disconnected and can be moved. Embed the ropes at the edges of the two diaphragms, and insert the two ropes into the aluminum splint with two openings (like the dumbbells lying horizontally). The aluminum plywood is also disconnected. The waterproof performance of this bonding method is worse than that of planting. A simple method is to arrange many diaphragms in a row and fix them. This is a simple and quick installation method, but it cannot be waterproof. In the face of earthquake, buildings will suffer catastrophic damage. Inflatable membrane structures have advantages. Even when the power supply of the power grid in the disaster area is suspended, the standby generator can ensure normal operation. Useful to protect life safety.
