UV is the English abbreviation for Ultra VioletRay, and its application range for industrial UV wavelengths is from 200nm to 450nm The process of using UV radiation to harden a material is called the UV Curing Process.

The UV curing device consists of five parts: light source system, ventilation system, control system, conveying system, and box body. The light source system is the core device, which consists of UV lamps, lampshades, transformers (ballasts), and capacitors (triggers). There are two types of UV lamps in the UV lamp market: high-pressure mercury lamps and metal halide lamps. High pressure mercury lamps are commonly used in domestic equipment, while some imported equipment uses metal halide lamps. The power generally needs to meet the requirement of 80-120W/cm, but the larger the power, the greater the heat. Therefore, the power should be selected according to the different curing materials and curing speed. The maximum lifespan of UV lamps is generally 800-1000 hours, and they should be replaced immediately after reaching this period, as the intensity of the ultraviolet light emitted by UV lamps during this period weakens, which can affect the curing effect.

When starting the UV curing machine, the light should be turned on first, and the fan should be turned on 2-3 minutes later; After shutdown, the fan should continue to operate until the lamp tube and the box cool down; Wait until the lamp tube is completely cooled before starting again.

When selecting a curing machine, the main parameters to consider are:

1. Luminescent area: The size of the luminous area directly determines the cost and also corresponds to different heat dissipation requirements.

2. Light intensity: The unit of light intensity is MW/cm2. Generally, the UV glue curing light intensity does not need to be too high, and around 1000mW/cm2 is optimal.

3. Wavelength: The wavelengths of the UV glue curing machine are mainly distributed at 365nm, 385nm, 395nm, 405nm, and 415nm.
