UV material foil: the technological art of balancing absorption and transmission

Dual requirements for UV absorption and transmission
The main design purpose of UV material foil is to efficiently absorb ultraviolet rays and protect the contents inside from photoaging, fading or chemical property changes. This feature is particularly important in the fields of cultural relic protection, art preservation, food packaging and outdoor advertising, effectively extending the service life of items and maintaining their original quality. However, in some specific situations, ultraviolet rays are not entirely harmful, but become a key factor in achieving specific processes or functions. For example, in ultraviolet curing technology, ultraviolet rays of specific wavelengths are used to accelerate the curing process of resins, coatings or adhesives, significantly improving production efficiency; and in the medical and health fields, ultraviolet rays are widely used because of their powerful sterilization capabilities Used in disinfection equipment to effectively kill bacteria and viruses in the air.

The art of regulating ultraviolet transmittance
In order to meet the above dual needs, the research and development focus of UV material foils has gradually shifted to the precise control of ultraviolet transmittance. Ultraviolet transmittance, as a key indicator of a material's ability to allow ultraviolet penetration, directly determines the material's applicability in different application scenarios. By adjusting the material formula, changing the film thickness, introducing special additives or adopting a multi-layer composite structure, scientific researchers can accurately regulate the absorption and transmission ratio of UV material foils to meet the individual needs of different industries for UV management. .

Application examples: the integration of technology and life
Ultraviolet curing field: In industries such as 3D printing, electronic packaging, and paint curing, UV material foils are designed to have specific ultraviolet transmission windows, ensuring that only ultraviolet rays of specific wavelengths can penetrate, promoting rapid curing of materials while avoiding damage to Unnecessary exposure of operators.
Medical disinfection equipment: In medical equipment such as ultraviolet disinfection boxes and air purifiers, UV material foils can not only effectively block short-wave ultraviolet rays that are harmful to the human body, but also allow UVC band ultraviolet rays with significant sterilization effects to penetrate, achieving efficient and safe disinfection. Disinfection process.
Smart agriculture: Modern greenhouse planting technology uses ultraviolet light of specific wavelengths to promote plant growth and enhance crop stress resistance. The UV material foil plays the role of regulating light quality here to ensure that plants receive the best lighting conditions.
