Principle of ultraviolet curing:
It is a process that under ultraviolet radiation, the photoinitiator in liquid UV materials is excited to become free radicals or cations by using the short and medium wave (300-800 nm) of ultraviolet light, thus initiating the polymerization of polymer materials (resins) containing active functional groups into insoluble and insoluble solid coatings.
The lamp of nail-baking lamp uses ultraviolet lamp tube, so it is also called ultraviolet nail-baking lamp, which can quickly dry and apply nail polish on the surface of nails. In addition, it is most commonly used to quickly dry gel nails.
Extended data:
Scope of application of ultraviolet lamp:
1, spraying: mobile phone shell spraying, cosmetics shell, MP3 small household appliance shell and other plastic spraying companies, mobile phone shell spraying and uv printing have different requirements for uv, depending on his products and equipment.
2. Printing: screen printing, offset printing and five-color printing are mostly used. Like U disk and CD-ROM, uv protective glue is used, and uv ink is also used for screen printing when printing CD-ROM.
3. Shoe industry: ultraviolet rays are used to irradiate the materials of soles to make them react chemically, so that the adhesive has good affinity with soles and uppers. Footwear is suitable for gluing, and uv glue is used for plastic bonding, such as plastic tube bonding for hospital infusion.
4. Wood industry: only surface coating is carried out, because uv coating (varnish, etc.). ) Good performance in all aspects.
Such as wear resistance, acid and alkali resistance, weather resistance, etc. After uv coating, the wooden floor and other surfaces can feel gorgeous. Most of the lamps used in wood painting are long.
