If the curing effect of the UV flatbed printer is good, the service life will be longer. This article will talk about what to do if the curing effect of the UV flatbed printer is not good?
1. What should I do if the curing effect of UV flatbed printer is not good?
UV printer uv light curing has three elements:
1. Spectrum, that is, whether the light emitted by the light source such as UV flatbed printer UV lamp is consistent with the absorption spectrum of the cured product.
2. Intensity, that is, whether the light emitted by the UV flatbed printer light source is sufficient to cause a photochemical reaction of the cured product. Due to the performance and dosage of the sensitizer inside the cured product (UV coating, ink, glue), the main agent and the amount of The light transmittance and sensation are also different, so the curing strength requirements are different.
3, the curing speed, too fast curing speed can not complete curing, and too slow will have a bad effect on the cured product. Such as pattern cracking, poor adhesion, etc. The curing speed varies with different cured products.
2. Summary of UV printer manufacturer Dacen
The UV lamp tube of UV flatbed printer mainly refers to the lamp tube that can emit ultraviolet light. When it emits light, it is accompanied by high heat, because it not only excites ultraviolet light, but also accompanied by infrared emission. The light wavelength is concentrated at about 365mm. The ratio is different due to the content of different quality lamps. Normal domestic UV lamps have a longer ultraviolet of about 30%, while imported UV lamps have 40-50% content. At the same time, the heat generation is also long and the service life is long, up to 2000 hours. The lamp only lasts about 1000 hours.
Some industry personnel often encounter the phenomenon of incomplete curing of UV ink and sticky surface during the printing and production process of UV printers, resulting in unsatisfactory printing results. This article is "What should I do if the curing effect of UV flatbed printers is not good?" All the content, I hope to help you.
