Special Adhesion PIJ Inks
UV inkjet printer ink is a special ink based on ultraviolet (UV) curing technology, and its composition and characteristics give it significant advantages in the field of industrial inkjet printing. The following provides a comprehensive description from the aspects of composition, characteristics, applications, and technical parameters:
UV inkjet printer ink is mainly composed of the following components:
Resin: As the main film-forming substance, it determines the adhesion and physicochemical properties of ink. Common types include acrylic resin, epoxy resin, etc., providing high hardness and wear resistance.
Photoinitiator: The core component that absorbs ultraviolet light and triggers the polymerization reaction of the resin, achieving rapid curing. For example, a reaction can be triggered under LED-UV light source.
Additives: including leveling agents (to improve ink leveling), defoamers (to prevent bubble formation during spraying), antioxidants (to enhance stability), etc.
Pigments/Dyes: Nanoscale particles (such as special black UV ink) ensure bright colors and excellent light resistance.
Low volatility solvent: used to adjust ink viscosity, ensure smooth spraying, and leave no residue after curing.
Rapid curing: Instantly dry (in milliseconds) through ultraviolet irradiation (usually LED light source) to improve production efficiency. After printing, it can be directly stacked to avoid adhesion.
High adhesion and durability: After curing, a network structure ink layer is formed, which is resistant to water, alcohol, friction, high temperature (up to 100 ºC), and chemical corrosion (such as solvent wiping).
Environmental safety: Does not contain volatile organic solvents (VOCs), meets the hygiene requirements of food and drug packaging, and has passed international environmental certification.
Strong adaptability: Suitable for a variety of materials, including metal, glass, plastic (such as PC, PE, OPP), ceramics, aluminum, etc., even stable adhesion on curved or rough surfaces.
High resolution printing: precise ink droplet control, supporting high-resolution (such as 180dpi or above) printing of complex graphics, QR codes, etc., close to the printing effect.
Food and drug packaging: Due to its non-toxic and odorless properties, it is suitable for labeling and packaging coding in direct contact with food.
Industrial material identification: such as metal pipes, electronic components, building materials, etc. that require long-term weather resistance identification.
Smart cards and precision components: high-precision coding or anti-counterfeiting information is printed on the surface of the smart card to ensure long-term clarity.
Variable data printing: supports online real-time printing of dynamic information such as serial numbers, dates, batch numbers, etc., suitable for automated production lines.
Nozzle adaptation: Compatible with various industrial grade piezoelectric nozzles, such as Ricoh GEN 4/5/6, Kyocera KJ4A, and Dimatix QE A30.
Curing conditions: UV-LED light source (wavelength 365-395nm) should be used, and the curing energy should match the ink formula to ensure complete drying.
Environmental requirements: The working temperature should be between 0-35 ° C, the humidity should be between 30-80%, and the storage temperature should be controlled between 0-40 ° C to avoid ink deterioration caused by high temperatures.
Safety protection: Photoinitiators may be irritating to the skin, and gloves and goggles should be worn during operation.
Nozzle maintenance: Regularly clean the nozzle (such as using specialized cleaning solution) to avoid clogging; Seal the ink path to prevent solidification during shutdown.
Storage management: Store in a dark and cool place. Use as soon as possible after opening to avoid prolonged exposure that may cause pre curing.
