Shelf life of new tensile membrane fabric
There’s a nuance to the shelf life of tensile membrane fabric recommended by some material manufacturer . While it doesn’t have a hard expiry date like food, there can be quality concerns related to storage conditions:
Impact of Storage Conditions:
- Humidity: High humidity during storage can cause the fabric to absorb moisture, leading to mildew growth, weakening the fibers, and potentially affecting the welding process.
- UV Exposure: Prolonged exposure to UV light, even before welding, can initiate degradation in some fabrics, especially those not specifically formulated for UV resistance. This can lead to a decrease in strength and flexibility.
- Improper Handling: Rough handling or exposure to sharp objects during storage can damage the fabric, making it unsuitable for use.
Manufacturer’s Recommendations:
- Most reputable tensile membrane fabric manufacturers provide specific storage recommendations. These typically involve:
- Climate-controlled environments with moderate humidity levels.
- Protection from direct sunlight and UV exposure.
- Proper stacking or rolling techniques to avoid creases or damage.
Impact on Welding:
- Fabric stored improperly can have a negative impact on the welding process.
- Moisture absorption can affect the adhesive properties of the welding material.
- UV degradation can make the fabric more brittle and less receptive to welding.
Here’s how to ensure quality:
- Follow storage recommendations: Adhere to the manufacturer’s guidelines for temperature, humidity, and UV protection during storage.
- Inspect before use: Prior to the welding process, thoroughly inspect the fabric for any signs of damage, mildew growth, or brittleness.
- Use within recommended timeframe: While there might not be a strict expiry date, some manufacturers suggest using the fabric within a specific timeframe for optimal performance during welding.
In essence:
Tensile membrane fabric itself doesn’t have a set expiry date, but proper storage conditions are crucial to ensure quality for the welding process and the long-term performance of the final structure. By following manufacturer’s recommendations and conducting proper inspections before use, you can ensure the fabric performs as intended.
