ETFE Membrane Structure Building Response Measures and Maintenance Programs

1. response measures

Regular inspection:

Regularly check the ETFE film structure, focusing on the surface of the film, the connection part, the installation bolt and other parts.

Check whether the film material has scratches, cracks, aging and other phenomena, to ensure that abnormal conditions are discovered and dealt with in time.

Cleaning and maintenance:

The ETFE membrane structure is cleaned regularly to maintain its appearance and performance.

Use mild cleaning agents and avoid harsh chemical cleaning agents to avoid damage to the surface of the film.

Regular maintenance of the ETFE membrane structure, including application of waterproof coating, repair of damaged membrane material, etc.

Reinforcement measures:

For the parts that are prone to damage, reinforcement measures are taken, such as increasing the support structure and strengthening the connection parts.

2. maintenance plan

Repair of minor damage:

For small damage (less than 30mm in diameter) or long scratches on the film surface, special tape made of ETFE film can be used for maintenance and repair.

Before repair, clean and dry the parts that need to be repaired to ensure the bonding effect of the repaired materials.

When using ETFE tape, pay attention to the adhesive tape and the film surface need to be firmly fitted, there should be no adhesive bubbles, and the pasted tape should not be warped around.

3. Repair of larger damage 

For the damage area of the film surface is large (more than 30mm), first determine whether it can be repaired with ETFE tape according to the actual situation.

If it cannot be repaired, the entire ETFE air pillow needs to be replaced.

The ETFE air pillow needs to be re-customized and installed to the same specifications.

Handling of special cases:

If the damage is caused by the pressure increase inside the air pillow beyond the endurance range, or the cracking of the film splicing and weld in the middle and edge of the air pillow, it is necessary to develop a maintenance plan according to the specific situation.

ETFE membrane structure buildings need to take a series of countermeasures and maintenance programs during use to ensure their safety and service life. These measures and programs include regular inspection, cleaning and maintenance, reinforcement measures and repair methods for different damage conditions.

In the process of use, regular inspection and maintenance should be carried out to discover and deal with problems in time to avoid greater losses. At the same time, the appropriate repair materials and processes should be selected and operated in accordance with the instructions to ensure the quality and effect of the repair.
