In recent years, new do mark with the pen
with a thicker, lighter ink coverage key parts to do mark, marked with a
symbol, not blocking the text at a glance. The most important role is: the
highlighter did mark the file copying, once did not see the mark!
The key principles of the UV fluorescent
ink visible fluorescence with ultraviolet excitation (DEA) and compound is
added in the ink. , And then release of additional energy is absorbed by the
absorption of light energy, resulting in the energy level transitions of atoms.
The security feature is in the irradiation of ultraviolet light (200nm ~ 400nm)
emits red, yellow, green, and blue visible light (400nm ~ 800nm). This ink
colored and colorless divided longwave (365nm) and short wavelength (254 nm).
Fluorescent pigment organic complexes, grinding refinement, emitting high,
usually colorless or pale white in ultraviolet light (200nm ~ 400nm)
irradiation, side showing a variety of colors of visible light (400nm ~ 800nm).
According to the wavelength of the excitation light source can be divided into
short-wave ultraviolet excitation fluorescent pigment (excitation wavelength
254nm), and ultraviolet excitation pigment (excitation wavelength of 365nm).
Highlighter fluorescent agent, it
encounters more ultraviolet light (sunlight, fluorescent lamps, mercury lamps)
will produce the fluorescent effect, a white light, so that the color looks
dazzling fluorescent feeling.
Also can hide colorless highlighter color
after writing, you can display the contents of the writing pen behind violet
light irradiation.
Highlighter fluorescent our watches,
fluorescent light sticks principle is not the same, light sticks inside the
radioactive reaction generated ray excitation, the outer periphery of the
light-emitting phosphors, in the night, so they do not have any UV luminescence
can. Highlighter is necessarily fluorescence ultraviolet circumstances will you
highlighter handwriting near mosquito lights, Detector can be seen very
clearly.
The highlighter smell toxic?
The highlighter is divided into two kinds
of water-based and oil-based.
Similar to the water-based pen and a color
pen and is nontoxic, but not easy to dry. And the coverage is not good, not
write up the surface of some items, the two colors will appear stacked dirty.
Oily pen color synthetic solvents dissolved
in alcohol, some sensitive people smell the taste will produce dizziness. But
it is easy to write, easy to dry, the coverage is good, the price is also
cheaper.
The highlighter principle, and then release
the extra energy absorption by the absorption of light energy to produce atomic
energy transitions. Highlighter added some fluorescent agent. Some fluorescent
substances toxic, potentially carcinogenic ingredients, long-term use of
harmful, some small workshops toxic fluorescent agent in order to reduce costs,
raw materials as a highlighter. In addition, due to the highlighter containing
a large number of fluorescent agents, long-term use, can also seriously affect
the child's vision.
