Luminous powder to use for printing paste

General printed fabrics , patterns will not be displayed at the light , but in the play equipment, evening dress and decorative cloth , the pattern will be asked to be able to show at the glittering effect, this stamp is called luminous printing. This luminous garment both special warning, but also has special artistic effects. For example, glow in the dark dye the literary arena concert singer , dancer , had put on such a luminous costumes , colorful lights hit the singer 's body , the luminous clothing can fully absorb the irradiation stage lighting , stage lighting and then suddenly disappear , theater a dark , luminous clothing only singer who still shiny hair , beautiful magical glow refreshing , light color dreamlike , strange light enveloped wonders for the actor adds artistic charm.
Although the printing paste is made luminous luminescent light-emitting material ( luminous ) made ​​of transparent printing paste deployment . But for printing paste composition requirements should be phosphorescent sand, paste , add the additives are supporting no effect on the luminescent material ( luminous ) , can be the company's point of luminous gold , gold luminous powder is non-toxic harmless environmentally friendly .
Phosphorescent material content before printing press ( luminous ) is 20 to 25% ( by mass ) added to the printing paste , then mix thoroughly medium speed --- mantle velocity can be used for printing on the machine . Do not mix both speed when beating Gao avoid affecting glow.

Luminescent paint application methods

* Luminescent paint
Phosphorescent paint phosphorescent pigment is mixed into paint and varnish -like coating . Varnish must be highly transparent , and selection of the material to be coated and the coating method ( brushing , injection , spraying , coating machinery , etc.) is also necessary.
In addition , we must take into glow in the dark stones and other coating properties , if the choice can improve the stability of the luminescent light lacquer paint better.
Phosphorescent paint and varnishes standard mixing ratio of 1:1 by weight . Luminescent pigment content the higher the brightness is also higher.
Luminescent coatings for transparent varnish ( excitation light transmittance of light release ) the higher the brightness is higher .
Varnishes and thinners used in luminescent paint must not contain any heavy metals because of chemical reactions luminescent pigments and heavy metals will make it degenerate and luminous failure.
Phosphorescent paint coating of standard fluorescent pigments 0.1mm, brightness higher the thicker the coating , when saturated at about 0.3mm.
1 g phosphorescent pigment and 1 g of a mixture of varnish coating may be applied in the area of 0.1 ( thickness ) X10X300mm.
When part of the background painted white , brightness effect after coating the best .
For example, the coating thickness of 0.1mm phosphorescent paint on a white background of light attenuation rate is set to 0 , then the silver is 10 - 15% 30 --- 35% green , and black on the dimming rate of up to 45 --- 50%.
