According to the data, the membrane substrate of membrane structure can be divided into three categories: PVC, PTFE and ETFE.

The cost of PVC membrane structure materials is relatively low. This kind of membrane structure material was developed and applied earlier. The service life of general PVC membrane is 5-15 years depending on the application environment.

Compared with PVC, PTFE data has high data and processing costs. Glass fiber is used as the base material of such membrane structure data, and Teflon is used as the external coating. The data has good self-cleaning property and long service life, which can generally reach more than 20 years.

The price of ETFE membrane material is high, but because it is very light, the cost of supporting structure and membrane structure foundation engineering can be greatly saved. The service life of ETFE membrane shall be at least 25-35 years. This kind of membrane structure membrane material is an ideal material for multi-layer movable roof structure.

Normal companies will use high-quality membrane structure data, because the quality is relatively more stable, of course, good data means high costs.

Workers should not wear hard soled shoes to directly contact the surface, so as to avoid sand abrasion and severe abrasion of the surface. Membrane structure landscape

When cleaning the surface of the membrane, clean it with clean water or neutral detergent, not with acidic or alkaline solvent such as gasoline, alcohol, chlorine water, etc. Foreign matters such as iron parts, chemicals or other colored materials should not be accumulated on the surface of the film for a long time.

The steel structure, steel cable, plywood, bolt and other components in the structure shall not be adjusted or disassembled without the approval of the manufacturer.

It is not allowed to pull or hang heavy objects and articles on the membrane materials without permission.

The user shall regularly (half a year to one year) carry out rust prevention and maintenance on the steel structure to ensure the structure and prevent rust water from dropping on the surface of the film material.

As a modern building structure, the membrane structure scene is a space structure with a certain rigidity, which is a high-tech project integrating architecture, structural mechanics, fine chemicals and information science, by combining the high-strength and flexible membrane data with the tensioning system.

The membrane structure scene project can provide a variety of uses and create a happy space for people to enjoy. It fully demonstrates the artistic beauty of clear force bearing of structural components. Because of the color rendering of the film material itself, it not only provides people with a space to shade from the sun and rain, but also can form a colorful scene under the reflection of colored lights at night. Because this lively shape can bring people fashionable and relaxed leisure feelings, it is widely popular.
