How to determine whether the woven bag has been damaged by ultraviolet light

Determining whether the woven bag has been damaged by ultraviolet light is an important task, because ultraviolet light is a strong radiation that can cause irreversible damage to the woven bag. If the woven bag is damaged by ultraviolet light, it may lead to its strength reduction, brittleness, aging and other problems, thus affecting its service life and safety. The following are some methods summarized by Chengdu woven bag custom manufacturers to determine whether woven bags are damaged by ultraviolet light:

1. Visual inspection: Through visual inspection, we can preliminarily determine whether the woven bag is damaged by ultraviolet light. If the surface of the woven bag appears fading, yellowing, cracking, deformation, etc., it may be because of UV damage. These phenomena are usually due to the absorption of ultraviolet energy by the woven bag, resulting in changes in its molecular structure.

2. Tactile inspection: Through tactile inspection, you can judge whether the woven bag has become rough, hard, brittle, etc. If the woven bag becomes rough, hard, brittle, etc., it may be because of UV damage. These phenomena are usually due to the absorption of ultraviolet energy by the woven bag, resulting in changes in its molecular structure.

3. Physical test: physical test can determine whether the physical properties of woven bag such as tensile strength and elongation at break have changed. If the physical properties of the woven bag change, it may be because it has been damaged by ultraviolet light. These phenomena are usually due to the absorption of ultraviolet energy by the woven bag, resulting in changes in its molecular structure.

4. Chemical test: Through chemical test, you can determine whether the woven bag is damaged by ultraviolet light. For example, UV absorbent can be used to test the UV resistance of woven bags, or UV irradiation can be used to test the weather resistance of woven bags. If the anti-ultraviolet ability of the woven bag is poor, or there is a significant aging phenomenon after ultraviolet irradiation, it means that it has been damaged by ultraviolet light.

5. Laboratory testing: If you need more accurate test results, you can send the woven bag to a professional laboratory for testing. The laboratory can use various test equipment and methods, such as ultraviolet intensity meter, ultraviolet illuminometer, ultraviolet aging test chamber, etc., to determine whether the woven bag is damaged by ultraviolet light. These test equipment and methods can more accurately test the UV resistance, weather resistance and other indicators of the woven bag, so as to determine whether it is damaged by ultraviolet light.

To sum up, judging whether the woven bag is damaged by ultraviolet light requires comprehensive consideration of many aspects. In actual operation, the appropriate method can be selected according to the specific situation. If the woven bag is damaged by ultraviolet light, corresponding measures need to be taken in time to repair or replace it to ensure the quality and safety of the product. When choosing woven bags, factors such as their UV resistance and weather resistance should also be considered to ensure that they can be used in the outdoor environment for a long time. In addition, care should also be taken to avoid exposing the woven bag to strong sunlight, or to protect it with anti-ultraviolet materials to reduce the damage caused by ultraviolet light.
