Common USES of rare earth elements

Here we will talk about the timing of the application of various rare earth elements in order to make a better distinction between light rare earth and heavy rare earth: Promethium (Pm) : promethium is a man-made radioactive element produced in nuclear reactors. For vacuum detection and satellite to provide auxiliary energy. Pm147 gives off rays of low energy to make promethium batteries. Power for missile guidance instruments and clocks. The batteries are small and can last for years. Promethium [...]

Introduction of various types phosphorescent materials

Phosphor types use a phosphor “phosphor” “Inorganic powder material at a certain excitation conditions can be light, sometimes also called light pink, crystalline phosphors or phosphor according to the type of excitation mode can be divided into organic light-emitting phosphor, the electroluminescent phosphor, cathode ray luminescent phosphors and phosphor luminescence radiation and so on. 2 photoluminescent phosphors “photo luminescent phosphor” Emitting excitation light can be an inorganic powder material. Excitation light can be ultraviolet, visible, near-infrared bands. 3 fluorescent high pressure mercury lamp phosphors [...]

How to distinguish luminous powder and fluorescent powder

Luminous and phosphor are the two products, but many people think that is luminous phosphors and think they are following the same substance, small to give you how to distinguish luminous powder and phosphor.: 1 luminous powder: Yes absorbance – STORING – a self-luminous light emitting material, which is a kind of luminous material can be made visible in the dark, called luminous powder, luminous powder it into long-term, short-acting luminous, radioactive luminous, but they are of a material glowing [...]

Luminous nail polish

Also known as “nail paint.” Its main components are 70%-80% volatile solvents, 15% nitrocellulose, a small amount of oily solvents, camphor, titanium dioxide and oil-soluble pigments. The film formed by the luminous nail polish applied to the nail is firm and has a moderately colored luster to protect the nail and impart a beauty to the nail. Nail Polish, nail color, Nail enamel Main ingredients: long-lasting luminous powder, volatile solvent, nitrocellulose, oil, etc. ingredient The composition of ordinary luminous nail polish generally consists [...]

About Phosphorescent Emergency

The innovative glow-in-the-dark pigment as a substitute for radioactive self-luminous pigment for watches and clocks is rapidly becoming a useful material for safety systems in commercial aircraft. “Go!! Go!!” An instructor shouted the order to evacuate the dark cabin. Passengers left their seats and groped for a way to escape. They stooped to avoid the smoke, and saw a line glowing brightly on the floor. It was the phosphorescent evacuation path marking! Passengers followed the glowing line to the emergency [...]

Application of luminous screen printing ink

In order to obtain a more ideal luminous prints, its ink use skills are key. After the ink is determined, the luminosity of the printed matter depends on the thickness of the printing coating. 1. Screen plate production: a) select polyester monofilament mesh below 80 mesh; b) make thicker screen plate. This screen can be a single printing of a thicker layer of ink. 80-150 mesh mesh mesh is ideal. 2, luminous ink printed on white or light substrate [...]

What is the principle that phosphor gives off light ?

One, “phosphors” luminous enlightenment In order to find out the chemical composition of phosphor powder, we first thought about the luminescence of fireflies. The luminescence principle of fireflies mainly has the following series of processes. Photoforming protein + photoforming enzyme containing oxygenated photoforming protein (emitting green light) Oxygen-containing photogenic protein +H2O photogenic protein That’s why fireflies glow continuously, with flashes of light. It’s worth noting that the green light emitted by fireflies is a “cold light” with a conversion rate of 97%. Secondly, we [...]

About photoluminescent inkjet paper

The ideal superior photo quality glossy paper for digital photos and color print-outs Most suitable for high-resolution printers. Photo quality printing in dazzling and strongly contrasting. Excellent ink absorption, quick drying, perfect reproduction of small characters, more real and clear. Photo quality printing in dazzling and glowing in the dark. Directions for use Do not touch the printable side of paper. Moisture and oil from your skin can affect print quality. Hold paper by the edges. Only suitable for ink jet printers. Unavailable for laser [...]

Phosphorescent Injection Molding Recommendations

Avoid exposing product to strong acids and or heavy metal compounds as they will react with the glow component and destroy the phosphorescent effect. Keep Moisture content of product to a minimum. Moisture content should be no greater than 00.05 – 0.10%. Minimum Drying time should be 2- 4 hours at 180℉(Fahrenheit) in either a dehumidifier or hopper dryer. It is recommended that a dew point of -20℉(Fahrenheit)   be achieved for the inlet air Phosphorescent master batches or compound material [...]

Basic knowledge of rare earth

Rare Earth Rare Earth Rare Earth Rare Earth Rare Earth Rare Earth Rare Earth Rare Earth Rare Earth Rare Earth Rare Earth Rare Earth Rare Earth Rare Earth Rare Earth Rare Earth Rare Earth Rare Earth Rare Earth Rare Earth Rare Earth In fact, this is just a misunderstanding left over from the 18th century. Several rare earth elements were discovered successively after 1787, but the corresponding mineral discoveries were few. Due to the limitations of science and technology [...]
