What is the principle of UV curing machine?

What is the principle of UV curing machine? Nowadays, UV curing machines are widely used in our daily lives. Widely used for screen printing, planographic printing, relief printing, adhesive trademarks, metal nameplates, KT boards, glass, ceramics, electronic components, single-sided circuit boards and other substrates to print crystal sugar coating, frosted, crystal gemstones, colorful convex oil, etc.
1、 Overview of UV Curing Machine
UV is the abbreviation for ultraviolet Ray, with industrial ultraviolet wavelengths ranging from 200 nanometers to 450 nanometers. The process of curing a "UV cured material" by irradiating it with ultraviolet light is called the "UV curing process".
UV curing machine is a surface treatment machine used for UV spraying of paper, PVC, plastic products, and curing of ink layers after printing. UV curing machine is currently a relatively environmentally friendly ink drying method. Under the excitation of instantaneous high voltage, the ultraviolet lamp can light up and emit ultraviolet light with a main peak of about 360 nanometers, which shines on the ink layer. The acrylic resin of the ink can crosslink and solidify.
2、 The principle of UV curing machine
Adding initiators (or photosensitizers) to specially formulated resins can generate active free radicals or ionic groups after absorbing high-temperature ultraviolet light in UV curing equipment, leading to polymerization, cross-linking, and grafting reactions. This allows resins (UV coatings, inks, adhesives, etc.) to transform from liquid to solid within seconds. Suitable for various industries such as PVC, plastic sheets, computer keyboards, mobile phone buttons, cameras, etc.
