How Many Bonding Methods Are There For Membrane Structure Engineering Membrane Materials?

How many bonding methods are there for membrane structure engineering membrane materials? Membrane structure engineering is formed by combining and splicing a large number of membrane materials, so the adhesion between membranes is very important. The adhesion treatment between the film and the film is not good, and water leakage and tearing may occur in the subsequent use. Not only affects the appearance but also affects daily use. The following introduces three bonding methods for membrane structure membrane materials.

1. Sewing bonding method: This is the most secure bonding method, but the sewing thread is easily damaged. Sewing bonding is usually combined with heat sealing and applied to the landscape coated polyester PVC coated polyester filament fabric in order to obtain a greater strength, if it is used outdoors Yes, the sewing bond should also be protected with a PVC covering. The sewing bond is not suitable for PTFE-coated glass fiber fabrics, and all other brittle cloth-based materials.

2. Heat-sealing bonding method: heat-sealing bonding is a method of melting the film material by heating, then applying pressure to connect them to each other, and finally cooling and forming. Heat-sealing bonding is used for PVC-coated polyester filament fabric and PTFE-coated glass fiber fabric. But for PTFE-coated glass fiber fabrics, since PTFE cannot be hot-melted by itself, it is necessary to use a different material for the inner layer.

3. Mechanical bonding method: There are three ways-one is to put the rope on the edge of the two diaphragms first and then use the splint to clamp the place where the two membranes overlap; the second is to bury the rope on the edge of the membrane first And put the rope into the aluminum plywood. Although it is similar to the previous method, the waterproof method of this bonding method is worse than the previous method; the third is to arrange multiple diaphragms in a row and fix it. The simplest and fastest but also the worst.

The above are the three bonding methods of membrane structure engineering membrane materials introduced to you. If you have any needs and questions, please consult Shanghai Zhanji!
