UV printer UV ink is poisonous

                    Is uv printer uv ink toxic? Many customers who buy UV printers now have a concern, is that the ink used in UV printers is toxic? Will it cause harm to the human body? Carle will explain it for everyone.

Uv printer UV ink is non-toxic, why?

UV printer UV ink is poisonous

                   The UV inks used by Hangzhou Kale are made of relatively environmentally friendly raw materials, and their toxicity is relatively low. However, UV ink is still irritating and corrosive to the skin. UV ink generally does not add any volatile solvents, so compared to other types of products, it has more environmental protection characteristics.

                   UV printer UV ink is a solvent ink that is universal for all materials. There are many chemical components of UV printer ink. Generally speaking, UV printer ink is based on the electric field force between the nozzle of the UV printer and the substrate. Role, while spraying on a predetermined area of the surface of the substrate to form a "liquid ink" that indicates the imprint of graphic information. Uv ink performance directly affects the output quality of material printing.

                   UV printer ink generally has the characteristics of stable physical and chemical properties, non-corrosive to metal objects such as nozzles, and is not easy to be burned and faded. The ink has good sprayability and good drying performance. It does not block the nozzle during spraying, and The nozzle wall is dry, but after the ink is ejected, it can be dried and firmly adhered to the surface of various types of printing materials; the ink's color density, viscosity, surface tension and other printing properties meet the needs of digital printing because the ink affects inkjet printing The vividness of the image, viscosity and surface tension directly affect the normal operation of inkjet.

                 Uv (ultraviolet light curing) ink refers to the use of ultraviolet light with different wavelengths and energy to polymerize the monomers in the ink binder into polymers under ultraviolet irradiation, so that the ink is filmed and dried. UV inks are also inks. As inks, they must have brilliant colors (except for special cases), good printability, and suitable curing and drying rates. At the same time, it has good adhesion, and has abrasion resistance, corrosion resistance, weather resistance and other characteristics.

                Uv ink is an ink that does not use solvents, has fast drying speed, good gloss, bright colors, and is resistant to water, solvents and abrasion. At present, UV ink has become a more mature ink technology, and its pollutant emissions are almost zero. According to statistics, the annual output of UV ink is about 16,000 tons in Japan, 18,000 tons in Europe, and 19,000 tons in North America. It should be noted that the water-based UV ink in UV ink is a new direction in the field of UV ink. Because the viscosity of prepolymers in ordinary UV inks is generally very large, it is necessary to add reactive diluents to dilute them. The currently used diluent acrylate compounds have different degrees of skin irritation and toxicity. At the same time as the low-toxicity diluent, another development direction is to study water-based UV inks, that is, water and ethanol are used as diluents. At present, water-based UV inks have been successfully developed and used in some printing companies.

                Therefore, UV ink is not poisonous, but it is not absolutely harmless, and hygienic conditions need to be paid attention to during work. There are many printer inks on the market. How to identify UV printer inks also needs to be understood.
