Specification:*
Material: stainless steel
Application: Station, subway fire safety channel
/>Features:
, using stainless steel plates of -mm national standard level 3 or above, stainless steel metallurgy is formed at one time under high temperature and high pressure. The surface graphics are etched and sunk, and the negative side is coated with light-storing material.
The light-storing material uses long-afterglow self-luminous material. After absorbing light for a short period of time - minutes, it can still continue to glow for hours in the dark. Its self-luminous material meets the following requirements:
Appearance color: light yellow or green powder.
Luminous color: light yellow gloss or green gloss.
Main peak wavelength of luminescence
Excitation light wavelength range:
3. The surface of the mark shall not be lower than the B/- level.
, the weather resistance, color adhesion, corrosion resistance, impact resistance, water resistance and radioactivity of the luminescent fire safety evacuation signs should comply with .3-Requirements
