glossy ink Precautions

1 , since the mirror silver ink dilute water, it should choose a high mesh screen , not only that, squeegee hardness should be more rigid .
2 , mirror ink must stir before using it with aluminum powder mixed resin to fully ensure the emergence mirror effect , otherwise , masterbatch glow in dark the produce mirror effect .
3 , printing ink mirror when temperature and humidity are very important, because the ink on the screen easy to dry, so we can not screen in air circulation , otherwise very easy to block network , when the air humidity, mirror effect backward , so in the screen printing to prevent air flow and moisture as possible.
4 , screen tension slightly lower , the net transfer from also nearer, and appropriate pressure reducing scraping blade, otherwise the mirror effect will undermine the formation .
5, printing machinery , which can not be used to back blade with a hard aluminum or stainless steel , while the gum back blade should be used to ensure Photoluminescent Ceramic ink coating uniformity mirror , the mirror effect is the same.
6 , mirror effect mirror the way the ink is drying on the mirror effect in terms of heating and drying naturally dry less good , and note should be consistent with warming temperatures and drying time , otherwise the mirror performance and color saturation will differ.
7 , we must first understand the dilute water mirror ink printing technique is the key, when the printing speed is slow, on the one hand , dilute the ink will leak water shed mirror screen , on the other hand , mirror ink easy to absorb moisture from the air , after printing mirror effect was not good , for at the time of printing, the ink mirror inverted version must be continuous and rapid network printing , printing to complete successfully , that is, the printing side of the workpiece edge to check this rate, will give the effect of impact printing , such as blocking network , printing ink does not go on the screen slagging Orchestra.

Due to the long afterglow luminescent Photoluminescent Gravel

Due to the long afterglow luminescent material removal can be light illumination in the dark a long time, so people will this material colloquially known as "luminous." Traditional luminous two categories: sulfur Compound-and radiation-excited type. photoluminescent paint Sulfide including ZnS, CaS, etc., and chemical properties of these materials are relatively less stable in water and ultraviolet light easily hydrolyzed or photolysis, Afterglow time is generally two to three hours, life is also shorter. Excitation radiation type is incorporated into radiant energy emitted by radioactive substances within the material as an excitation source, excitation and emission center Glow. Because such materials containing radioactive substances harmful to the environment and human health, Photoluminescent Ceramic has been banned in most countries use.

luminous materials are Photoluminescent Rigid Sheet

Long Afterglow 
Long-lasting storage luminous materials are photoluminescent (Photoluminescence) of a material, the excitation energy is the energy that can be any kind of ambient light, such as: sunlight, lighting, etc. 
. The basic principle of this luminescent material is: photoluminescent pigment suppliers a material preparation process, the doped luminescent center-forming element in the matrix and the center of the trap, when excited by external light, the light emitting center Electronic ground state to an excited state, when the electron transition from the excited state to the ground state, light emission is formed. Meanwhile, some of the electrons in the excited when falling into the trap center is bondage. After removal of light , Disturbed by ambient temperature, bound to fall into the trap out of the trap-state electronic energy released to stimulate the formation of a light emitting luminescent center. Since the electron is bound to trap affected by ambient temperature Disturbance Photoluminescent Ceramic gradually out of the trap, so luminous performance of a lengthy process, which formed a long afterglow.
