What Is a Curing Light?

The shadowless adhesive curing lamp refers to a type of adhesive that must be cured by ultraviolet light. It can be used as an adhesive, as well as a glue for paints, coatings, inks, etc. The glue requires corresponding ultraviolet light. To cure.

The shadowless adhesive curing lamp refers to a type of adhesive that must be cured by ultraviolet light. It can be used as an adhesive, as well as a glue for paints, coatings, inks, etc. The glue requires corresponding ultraviolet light. To cure.

I. Overview of shadowless adhesive: UV adhesive is also known as shadowless adhesive, photosensitive adhesive, and UV curing adhesive. It refers to a type of adhesive that can be cured by ultraviolet light irradiation. It can be used as an adhesive or as an adhesive. Paints, coatings, inks and other rubber materials are used. The glue needs to be irradiated with corresponding ultraviolet light to be cured.

Second, the working principle of shadowless glue curing lamp:

After the photoinitiator (or photosensitizer) of the shadowless rubber absorbs ultraviolet light (365NM) under the irradiation of ultraviolet rays, it generates active free radicals or cations, triggering monomer polymerization, crosslinking and grafting chemical reactions, so that the Change from liquid to solid in seconds.

Three, the classification of shadowless curing lamp:

According to different requirements, shadowless glue light sources can be divided into high pressure mercury vapor discharge lamps and low pressure mercury vapor discharge lamps.

1. High-pressure mercury vapor discharge lamp, also known as ultraviolet high-pressure mercury lamp, is used as a shadowless curing light source.

The main peak of external output is 365NM, its power density and UV output are strong, and the curing time is short. The lamp head can be made into a top type and a porcelain head, and the common power is 250W, 400W, 500W.

2. Low-pressure mercury vapor discharge lamp, also called fluorescent low-pressure mercury lamp, power is 20 / 40W, lamp length: 1200 , irradiance range: 50w / m2, ultraviolet wavelength: 290nm 400nm, its ultraviolet fluorescent light source It is more suitable for curing large-area shadowless glue. Due to the low power, the curing time is relatively long.
