1. Chemical formula: ZnS (doped Cu, Mn… The metal ions are non-toxic, not radioactive, and the powder is insoluble in water; 2. The recommended voltage is: ac 20v ~110v, frequency: 400HZ, customer adjustment; 3. Water vapor (or water) cannot be included in normal production, because water will affect the service life in the electricity. 4. In addition, the encapsulated film should be compact, otherwise it will be breathable and easy to enter. It is better to use glass for longer life.
Electroluminescence (EL) is the electroluminescent material that occurs when the electric field is connected to the electric field. When the electrons return to the ground state from the excited state, they are electroluminescent. Electroluminescent (EL) phosphor powder is mainly used in cold light tablets and cold light (light), converts electrical energy directly into light energy of a kind of inorganic powder luminescent material, its main emitting light colors are blue, green, orange, and the color color transition. Electroluminescent powder has been widely used in electronic products, Mp3, mobile phone, thin film switch, liquid crystal backlight, automobile, ship, medical equipment and aircraft instrument backlight; Flag lamp, fluorescent line; Advertising, building decoration, luminous gifts, advertising.
We can adjust the production process flexibly to meet the requirement of luminescent color, brightness, life and particle size of phosphor.
About EL phosphor film production
First, the raw material
1, EL phosphor;2, Silver;
3, EL phosphor dedicated barium titanate powder;
4, EL phosphor special adhesive glue (A / B plastic);
5, conductive glass (or conductive film);
6, packaging films.
Second, the process
1, EL phosphor drying temperature at 80 degrees;
2, configure phosphor slurry: EL phosphor in proportion with the adhesive glue stirring, to bubble, as required by controlling the viscosity;
3, the phosphor screen printed conductive glass paste (or conductive film), as required to control the thickness;
4, the carrier drying phosphor;
5. Configure barium titanate slurry ratio in accordance with the requirements of control, viscosity, to bubble;
6, the upper screen printed with phosphor carrier barium titanate paste thickness control;
7, drying over carrier;
8, screen paste, as required to control the viscosity and print thickness of the slurry;
10, welding lug;
