The widespread use of uv printers, the more obvious feature is that the hit and dry,

normally speaking, the drying speed of uv ink is instant. But there are also customers

encountered uv ink does not dry situation, so, what are the factors that affect uv ink drying?

UV ink is ultraviolet light curing ink, through ultraviolet absorption curing and film.

The main components of UV ink are photoinitiator, active diluent, prepolymer, coloring pigment,

auxiliary components are fillers, additives (leveling agent, deflaaming agent, polymer blocking

agent), wax, etc. The curing mechanism of UV ink is that under the irradiation of ultraviolet light,

the light initiator in the ink absorbs the radiation energy of ultraviolet light, and is stimulated to

generate a free radical layout design, thus triggering the prepolymer polymerization,

crosslinking and grafting reaction, and curing in a short time to form a three-dimensional

mesh polymer, which becomes a hardened film. The essence of UV ink curing is to achieve

curing by forming chemical bonds.

what are the factors that affect uv ink drying?Ulv wavelength and ink in the curing agent

matching degree is not high, lead to not completely reaction solidification, led lamp power

open is low, lead to the emitted energy can not reach the set standard, printing speed is too fast,

led lamp cannot immediately irradiation, is printed material for glass, ceramic tile, acrylic

smooth surface, unused coating, ink resin and monomer content is less, lead to bad quality.

This is a brief introduction to the factors affecting uv ink drying, buy your company's uv ink,

generally do not encounter these problems.
