Ink and glue curing are common in our life. Sometimes, we write something, and need to submit soon, we may need to curing it; or we draw a painting, and need curing it soon to avoid ruin it.

What is UV LED Curing

UV LED Curing: glue, ink or the like which after absorbing UV light from curing equipment in high-intensity ultraviolet light, change from liquid to solid.

The physical properties of the purple LED curable material is substantially affected by the impact of UV light curing machine. Whether protecting glue, ink, or adhesive, they are dependent on these parameters in curing UVLED chip design and method of control.

UVLED chip’s four key parameters:

1.UV radiometric (or density)

2 spectral distribution (wavelength)

3 radiation (or UV energy)

4. infrared radiation. With respect to maximum irradiance or radiation, as well as different UV spectrum, inks and rubber protective will exhibit very different characteristics. Identification of the different characteristics and their ability to UVLED chip and the optical properties of the curable material that matches the extension of the purple LED curing as a fast, efficient production processes range. There are many optical and physical properties of the curing system affect the curing effect, which leads to the appearance of different violet LED curable material properties.

Three Factors that Affect the quality UV Curing Effect

1, Power of UV curing flashlight: Usually UV light for curing ink required power 80-120w / cm, solid light energy is too high will cause the ink embrittlement, low-light energy can not reach the light solid results.

2, the suction device: When LED chips throw ultraviolet light, it would also generate some heat, the temperature of the body rising, light aircraft over the LED chip tube fitted with ventilation means, and through the exhaust pipe to suck the ozone outside so to cool the UV chip. If the substrate is too thin or very low temperature requirements, subject to curing test to determine whether it can meet the requirements.

3, UV curing flashlight wavelength: 365nm band spectrum is suitable for general light-curable ink (not applicable to wrinkles, and other ink with special spectrum requirements). Some UV machine due to the impact of the LED chip and the stray light too much, it will affect the curing effect, we advise clients test the wavelength of the 365nm UV flashlight before purchase it.

Tank007 provides various UV curing flashlights, such as UV31, UV Lo3, PT10, etc., such flashlights are good for curing.
