[UV curing] is widely used, not only in electronics, automotive, medical, automation and other industries, where the printing effect on iron cans is also very obvious.
1. Application prospect
In today’s increasingly high environmental protection requirements, the environmental protection of UV technology is also fully recognized, more and more iron can printing enterprises adopt UV printing technology to meet the increasingly stringent environmental requirements. In addition, UV technology can also save considerable costs for enterprises, such as the use of UV technology, there is no need for drying processes (traditional iron printing process to have more than 30 meters of drying room to dry the ink at about 150 degrees). Due to the non-absorption of the tinplate and the coating on the tinplate, it is not possible to use multi-color printing like the printing paper process, so the general traditional iron printing production line is mostly monochrome or two-color machine, and the production of a product often needs to be printed several times, and the use of UV technology can use four colors or even six colors at the same time, so that a product can be printed once. Can greatly improve efficiency.
Due to the advanced nature of UV technology and the applicability of the printing can industry, since 2004, COFCO packaging has transformed the original traditional printing wire into a UV line, the development of UV technology in the printing can industry has entered the fast lane.
2, UV iron printing material
At present, the materials used in UV iron printing technology are mainly inks, coatings and related auxiliary materials. Because UV ink, coating and traditional ink, coating there is a big difference, in this detail.
The main components of UV ink and glazing oil are polymeric prepolymers, photosensitive monomers, photoinitiators, auxiliary components are coloring pigments, fillers, additives (leveling agent, defoamer, inhibitor, slip agent) and so on.
UV printing ink has higher requirements for storage, which needs to be stored in an environment of 5-25 and the ink cannot be exposed in the air; Avoid heat sources and sunlight.
The technical indicators of UV polishing oil 971-0461 are: Main ingredients: UV acrylic acid; Solids: 97.5±2.5%(ASTMD-5403; METHODA); VOC: 0.08Kg/L; Viscosity: 65-95 seconds (25@Ford4 cups); Curing conditions: 3300±75mj/cm2; Film thickness: 5.4-7.0gsm; Temperature of preheating varnish: 32-38; Flash point: 93(closed cup); Coating properties: good adhesion and machining properties, high gloss, high hardness, excellent surface smoothness.
3, UV iron printing equipment
The main difference between UV iron printing equipment and traditional iron printing equipment is that there are UV UV drying between each printing unit.
