photoluminescent technology applied on the security aspect is its most common. In terms of security, the photoluminescent material may be used as security export indicator, evacuation and other markings. When used as these markers, the photoluminescent material must go through rigorous testing to ensure they meet safety standards. Application of different photoluminescent material with decorations or other small items on the security front, the luminescent material requirements to maintain the brightest light intensity and long duration of lighting. Secondly photoluminescence material exquisite products that do not belong to the product safety signs, T-shirts, promotional items, children's toys, small labels can use photoluminescent materials decorative printing.

● When using long-acting glow in the dark material in plastic, output products will be darkening phenomenon, which temporarily is no way to eradicate, but can be reduced.
There are two reasons for black: mainly luminous relatively high hardness, and process metal in contact with each other will produce friction, the surface of the metal oxide layer is black, after rubbing down in the product mix to black; followed by plastics prolonged high temperature will change color, luminous heat slowly and evenly dispersed in the plastic, indirectly increasing the time the high temperature of the plastic, the plastic will lead to discoloration.
Therefore, in use, to try to avoid contact with metal and reduce the high temperature time.
● luminous powder comprised of fine particles having a mixture which can not be dissolved. There are several luminous powder particle size division, to choose the right product according to claim luminous particle size.
● Short-acting luminous powder used in plastics no black phenomenon, the application easier.
● luminous light-emitting principle of simply withdrawing light - light, transparent plastic, the higher the easier the luminous effect performance.

glow in the dark film

Use white underlay in luminous where to buy glow powder or directly printed on a white substrate , can improve brightness and time printed pattern. If the underlying Color is dark , the light emission brightness to be reduced by 50 %.To get the desired brightness light-emitting pattern , glow in the dark film thickness of the luminescent ink should not be less than 100um.Since a lower mesh screen printing ink layer is thick, the effect can be obtained a light emitting pattern is preferable , and therefore it is preferable to use 80-120 mesh screen .

Based on the above characteristics

Based on the above characteristics, gravel for gardens advertising signs industry applications available from the following direction to think about where it's cold market 

1. Need to strong advertising (including: fast, permeability, weather) driven by commodities such as: 

tobacco, alcohol, beverages, credit card ...... or signs such as billboards and other advertising 

sales. 

2. Strengthen energy-saving and safety of the aspects (can replace traditional neon tubes). 

3. Liquidity marked glow in the dark stones with advertising boards, signs. 

lighting and other energy excitation

with the development and progress of science and technology , the emergence of new storage realglow ornamental gravel light rare earth -based alkaline earth aluminate phosphor material does not contain radioactive material. It differs from the traditional nature of the sulfide -and radiation- excited type luminous material , completely free of any harmful elements , chemically more stable, high brightness, long afterglow time . photochromic sheets storage luminescent material is a light-induced luminescence (Photoluminescence) material by ambient light , such as any kind of daylight , lighting and other energy excitation .
