UV curing lamps, by emitting UV light of specific wavelengths, can enable UV coatings such as UV glue and UV inks to cure rapidly, enhancing production efficiency and the weather resistance of printed products. UV curing lamps for printing is necessary to match the printing speed with the characteristics of the ink to ensure the curing effect and facilitate the realization of high-precision and high-speed UV curing production.

Description
Technical Parameters
High-pressure mercury lamps (such as UV glue curing lamps and uv ink curing lamps) are classic lights in the UV curing field. With their stable ultraviolet light output capability, they have long been applied in the curing processes of industries such as plastics, hardware, printing, coating, and electronics. It is a key device for promoting the improvement of industrial production efficiency. The core working principle is that the electrodes at both ends of the lamp tube discharge to excite the mercury vapor inside the tube to generate plasma, which then radiates ultraviolet light with wavelengths concentrated in the range of 200-450nm. Among them, the UV light with a wavelength of 365nm has the highest proportion of energy and can efficiently trigger the photoinitiator reaction within the UV material, achieving rapid curing.
In terms of performance characteristics, high-pressure mercury lamps have the advantage of broad-spectrum output and can be compatible with various UV inks and coatings, including solvent-based, water-based, and solvent-free types. It is suitable for printing on different materials such as paper, plastic and metal. In medium and high-speed production scenarios (such as full-wheel printing at 300-600 meters per minute), it can stably output curing energy, ensuring the surface gloss and adhesion of the product. However, it also has obvious shortcomings: it requires about 5 minutes of preheating time to start and cannot be started or stopped immediately.
In application scenarios, high-pressure mercury lights(such as ultraviolet ink curing light and epoxy resin uv light) are widely used in the production fields of food flexible packaging, self-adhesive labels, PCB circuit boards, etc. For instance, in food packaging printing, its rapid curing property can reduce the residue of harmful substances in the ink, meeting food safety standards. In PCB manufacturing, it can help the photoresist cure precisely and ensure the accuracy of the circuit.
