Long luminous emission time

Long-lasting luminous rare earth materials by a non-toxic environmentally friendly , save by absorbing visible light for 10-20 minutes , or more light emitted up to 12 hours in the dark , Photoluminescent Sand up to 15 years . Good weather resistance, can be used indoor and outdoor , resistant to temperature 400 ℃ -1000 ℃, widely used : watches, toys , photoluminescent paint, fire logo , injection products, silicone rubber, printing or spraying.
◆ Ink Application: Screen \ offset \ transfer \ printing \ spraying , ( paper \ fabric \ metal \ glass \ ceramics \ plastic ) .
◆ Powder Application: Injection PP \ PE \ PVC \ PC \ ABS \ AS \ PU \ EVA \ PMMA and silica gel .

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.

Discoloration of the six principles of electrochromic material

 1 , temperature change of raw materials: The temperature difference between the control change color. Temperature change various pigments have low to high temperature range , according to temperature generally divided into: low color ( about 10 ℃), the texture color ( about 30 ℃), High color (50 ℃, 60 ℃, 65 ℃) and other materials ; temperature change powder colored to colorless , colorless to colored series , temperature change with increasing temperature can be dropped repeatedly will change color. ( To 31 ℃ red , for example, more than 31 ℃ discoloration in the form of colorless presented below 31 ℃ is red ) .
 2 , Photoluminescent Sand discoloration principle: Dreaming of raw materials : use of sunlight (UV light ) control to change the color of the interior is a colorless or colored , color or appearance into another outdoor color under ultraviolet light .
 3 , luminous luminous pigments absorb light and heat energy , and energy storage , and then in the dark to light way slow release of energy can be recycled an infinite number of times , a faster sunlight and UV absorption.
 4 , long-lasting flavor: The aromatic microcapsules using microencapsulation technology , the flavors wrapped up membership glow in the dark dye , friction, heat or natural diffusion , etc., slowly release the aroma , flavor sustainable than six months.
 5 , anti-counterfeiting fluorescent material : surface colorless , showing color under ultraviolet light. Applications: money , bills , card , tobacco, alcohol , drugs, cosmetics, labeling, packaging , manuals , etc. have higher .
 6, the water becomes transparent ink : This ink is water-based , applied on paper , fabric printing, can cover the product as a white background when dry, discolored water after showing a transparent background color .

kinds of luminous color

The new light-emitting materials can be used as a luminescent pigment evenly distributed in a variety of transparent media such as paints , inks, plastics , rubber, paper, film , glass, ceramics, printing paste , used in clothing, footwear, stationery , watches, Photoluminescent Sand , signs, fishing gear and other consumer goods , but also can be used for architectural decoration, transport military measures , fire signs mark the import and export system , escape , rescue route signs , with the role of a good indication of the Fire .
Luminous range of applications :Long-lasting luminous powder luminous powder luminous powder luminous green color Type: luminous yellow-green , blue-green luminous , sky blue light luminous , luminous purple colored luminous , fluorescent luminous ,photoluminescent paint chart long-term thinking luminous high brightness, long lighting time , environmental adaptability, by absorbing various visible light automatic light, and can be recycled an unlimited number of permanent use , a very wide range of applications . The product is detected by the China Institute of Metrology , non-toxic , harmless , non-radioactive , lead, phosphorus and other harmful metals or chemicals , light new product is a new generation of environmental protection , safety, energy-saving luminous, bright light-emitting Si diagram pink highest emission time up to 12 hours.

Preparation of light- emitting material good performance

Sol - gel (So1-ge1) method is a very broad application prospects of nano- powder synthesis method , its main advantage is that at lower temperature synthetic products , and products with small particle size uniformity is good.Phosphorescent sand this SrAl2O4: Eu2 +, Dy3 + , the precursor material is an organic compound solution containing aluminum , with activator of activator, flux , catalyst compounds are organic solutions or aqueous mixture , water was added , remain in solution 2 ~ 3d, to form a gel , drying , removal of organic material , after ignition , and photoluminescent pigments N2 + H2 atmosphere ignition reduction derived carbon storage material . Sol - gel method can be prepared very good performance at the light emitting material , the reaction can be well controlled.
