FAQ

 What is photoluminescence? photoluminescent materials (commonly called “glow-in-the-dark”) has the ability to absorb light (sunlight, fluorescent, incandescent,etc) and then to emit light. When ambient darkness occurs, it becomes highly visible, lasting at least 8 hours. Our best products could last more than 20 hours.
Upon removal of the light source, the stored light is gradually released, the strongest glow is produced during the first 30 minutes of darkness, the most critical period following a power failure or other emergency. Then it fades over a period of time, when there is light again, it stores energy again. So the photoluminescence process is circulatory.
The bases of most photoluminescent products are photoluminescent pigments that can be incorporated into coat, paint, ink, fabric, ceramic glaze or porcelain enamel, glass, flexible and rigid molded plastics. Typical products include self adhesive flexible vinyl tapes, rigid PVC marker strips, and silk-screened signage. Photoluminescent fabric, enamel-coated sheet metal and ceramic tiles are also available.
What is traditional Zinc Sulphide pigment? Some of the first phosphors to be developed were inorganic zinc sulphide compounds. (German submarine commanders during World War I reportedly rubbed these compounds on their hands to read documents during blackout conditions.) These phosphors typically absorb energy from deep blue and ultraviolet light and emit it as yellow-green light.This is useful in that the peak spectral distribution of the emitted light roughly coincides with the peak spectral sensitivity of the human visual system under isotopic (low-level) lighting conditions (which is around 510 nanometers).
Zinc sulphide occurs in crystalline form, but is not photoluminescent by itself. This requires the addition of activator ions to the crystals, such as copper atoms. These ions absorb the excitation energy of the ultraviolet or visible light and later release it as visible light.
The copper-activated zinc sulphide crystals(identified with the chemical symbol ZnS:Cu) are typically ground into a fine powder with a grain size of 3 to 15 micrometers to avoid light trapping and light piping effects. This must be done carefully however, because the crystals can darken (or gray) if subjected to heavy pressure or excessive mechanical stress, due to disruption of the crystalline structure.
How efficient is the fire retardant of the firefighting security mark? Is it conforming to the regulations ofthe fire fighting department? 1. The products are tested to have conformed to the regulations of the firefighting department outright. 2. The firefighting security mark has been certified to be fire retardant. The oxygen index is above 32, which is compliant with the fire retardant standard.
In what types of places do the spontaneous security marks perform the best if deployed? In general, the spontaneous security marks are best suited for the well-lit sites of large space such as: the shopping centers/supermarkets of above 1500 square meters in size, high-rise buildings, underground complexes, etc.
