The use of UV release film precautions mainly include the following aspects:
1. Storage and custody
Temperature and humidity: UV release film should be stored in the indoor 25 ° C ±2 ° C, relative humidity 55%RH environment, to avoid high temperature, high humidity lead to material properties changes.
Avoid light: avoid UV light or direct sunlight to prevent material aging or performance degradation. When unpacking and using, it is also necessary to avoid natural light and strong light.
Shelf life: It is recommended to be used within 12 months after purchase to ensure the best performance of the material.
2. Preparation before use
Test suitability: When changing the application conditions or fitting objects, it should be tested on a small scale to confirm that it will not cause problems before using it on a large scale.
Cleaning work: Before use, ensure that the adhesive surface is clean and free of dust and oil to improve the adhesive effect.
Third, the film process
Operating environment: The film should be applied in an indoor environment with poor air circulation and no direct sunlight to prevent dust contamination and glue solidification too fast.
Film strength: When the film needs to use a certain strength, generally controlled in 3~5kg, to ensure that the film flat fit, to avoid bubbles.
Protect the screen: Before applying the film, tape can be used to cover the speaker hole, shutdown key, volume key and other positions on the screen to prevent glue from flowing into.
4. Curing and follow-up treatment
UV curing: According to the UV dose provided by the manufacturer, select the appropriate UV light wavelength (such as 365420nm) and exposure (such as 300400Mj/cm²) for curing to ensure that the glue is completely solidified.
Standing time: After the film should stand for 15 to 20 minutes, so that the UV film and the product bond more firmly, reduce the flying phenomenon.
Cutting and gluing: After the cutting is completed, try to unglue the same day, and attach the product for no more than 12 hours to avoid residual abnormalities.
5. Precautions
Avoid scratching: In the process of use, avoid using sharp objects to scratch the surface of the release film, so as not to affect the fitting effect.
Prevent static electricity: In the film process, attention should be paid to prevent static electricity, so as not to affect the bonding effect and material properties.
Safe operation: When using ultraviolet lamp for curing, attention should be paid to safety protection to avoid harm to the human body caused by ultraviolet light.
To sum up, the use of UV release film needs to pay attention to storage and storage, preparation before use, film coating process, curing and subsequent treatment and precautions. Only when these requirements are strictly followed can the best performance and fit effect of the UV release film be ensured.
