The application of reflective powder
Reflective powder is made of a glass based powder material,its main components are SiO2,CaO,Na2O,TiO2 and BaO,etc.The product can be directly added to the paint or silicone to endow a variety of products with the reflective effect,it is a core raw material of reflective fabric,reflective film,reflective paint,reflective signs,advertising material,clothing material,standard runway,shoes,hats,bags, life-saving supplies etc.
The introduction of reflective powder
Reflective powder is a kind of glass microbeads powder material, divided into three refractive index, ND≥1.90, ND≥1.93, ND≥2.2, specifications from 100 mesh -500 , the color is silver gray and white.
Chemical composition of reflective powder: SiO2,Cao,Na2O,TiO2, BaO.
Specific gravity: 4.2g/cc Appearance: clean, complete, transparent glass without impurities.
The feature of reflective powder
Reflective powder with high refractive index glass beads after half surface aluminized as a backward reflector, with strong reverse regression reflection performance, 85% of the light directly reflect back to the source of light, regression reflection caused by brightness, drivers and night operators in the night or poor vision clearly see pedestrians and obstacles, to ensure the safety of both sides.
The mechanism of reflective powder
When light shines on the surface of the microbead, due to the high refraction , the light is concentrated on a special reflector at the focus of the microbead. The reflector reflects the light through the transparent microbead and back to the light source, so that you can see very bright reflected light at the light source. According to the complex optical formula calculation, when the refractive index of the microbead is greater than 1.9, the regression reflection effect form. Reflective powder is the core material of reflective cloth, reflective ink, reflective coating and other new luminous functional composite materials. It's unique regression reflective characteristics ,produces a strong reflection effect.
The application of reflective powder
Reflective powder is the core raw material of reflective cloth, reflective film, reflective paint, reflective signs, advertising materials, clothing materials, standard racetrack, shoes and hats, school bags, life saving supplies and other new light functional composite material,can be widely used in roads, ports, mines, fire and other fields, as a safety sign. Through the coating machine can produce reflective film, screen printing reflective clothing, reflective paint,and so on.
