What should notice to use biodegradable glitter?

<p>Notes on the use of&nbsp;biodegradable glitter</p><p>Noctilucent powder to absorb all kinds of light and heat, is converted into light energy storage, and then automatically light in the darkness, by absorbing all kinds of visible light functions, the goods do not contain radioactive elements, and can be unlimited recycling, especially to short-wave visible under 450 nanometers, sunlight and ultraviolet light (UV light) has a strong absorption ability. So what does noctilucent powder need to pay attention to when using? Below small make up to introduce to you.</p><p>1.biodegradable glitter&nbsp;should be avoided in acidic environment. Because Al2O3 reacts with the acid.</p><p>2.biodegradable glitter&nbsp;should avoid contact with water and keep it sealed. Because contact with water will absorb moisture in the air, so that the&nbsp;biodegradable glitter&nbsp;black light and caking.</p><p>3.biodegradable glitter&nbsp;should avoid contact with metal, which will affect the unsaturated state of&nbsp;biodegradable glitter&nbsp;and affect luminescence.</p><p>4.biodegradable glitter&nbsp;should avoid high temperature and high speed friction, which will change the existing structure of&nbsp;biodegradable glitter.</p><p>Radioactive&nbsp;biodegradable glitter, is in the phosphor adulterated with radioactive materials, the use of radioactive materials continuously emitted ray to stimulate the phosphor to emit light, this kind of&nbsp;biodegradable glitter&nbsp;luminous time is very long, but because of toxic and harmful and environmental pollution and lead to a small range of applications.</p><p>Characteristics of&nbsp;biodegradable glitter</p><p>1. Short light storage time, high brightness, long afterglow time, rich color varieties.</p><p>2. Extremely stable physical and chemical properties, extremely strong environmental adaptability and extremely long service life.</p><p>3. Non-toxic and harmless no radiation, no combustion, no explosion, no other harmful heavy metal elements or chemicals.</p><p>4. Small particle size, uniform particle size distribution, easy to produce and process.</p><p>5. A number of independent intellectual property protection systems have been established for products made of this material.</p><p>6. Density ≈3.6gcm3 7. Good stability at -60℃-600℃.</p><p>7. After the color film treatment, the influence is weak in the strong acid and alkali environment, and suitable for use in the water paint&nbsp;biodegradable glitter.</p><p>8. Long afterglow luminescent materials of rare earth should not rub&nbsp;biodegradable glitter&nbsp;with metal for a long time.</p><p>9.biodegradable glitter&nbsp;meets eu environmental standards such as ROHS, SGS and EN71.</p><p>10. Description of product material composition mixture 4SrO.7AL2O3: Eu(Eu is a rare earth element).</p><p>Above is about biodegradable glitter when using some matters needing attention and its characteristic, hope can help to everybody.</p>
