The counter-burnishing powder is becomes by one kind of glass micro bead powder body material production, divides into three kind of refractive indices, namely: ND≥1.90, ND≥1.93, ND≥2.2 specification from 100 items----500 items may grade provide, the color has the silver-gray color and the white supplies the choice. The counter-burnishing powder is produces the reflection cloth, the reflection leather, the reflection to paste the membrane, the reflection coating and so on new illumination function compound materials core part, it has the return reflection characteristic and has the strong reflection effect from this. The counter-burnishing powder may widely apply in domains and so on traffic signal, marking, make of car, advertisement, runway, clothing, shoes and hats, book bag and aquatic means of rescue, takes the safety mark, enhanced user's security reliability greatly.
<dnt> the </dnt> high refractive index glass micro bead has the return echoing characteristic. The so-called return reflection is refers to, when the bundle of rays any angle based on this shines to the micro bead's surface, condenses as a result of the micro bead's high refraction on the micro bead focal point special reflection layer, reflection layer optical fiber along photo source direction parallel reflection one optical phenomenon. When the refractive index is bigger than 1.9, the micro bead's reflection only then has the good return performance.
<dnt> the </dnt> beaded glass, the siliceous sand stone, the sheet glass as well as the stained glass micro bead are the clothing dye printing, the clothing burn the picture, the Christmas tree incrustation, the man-made fruit, the man-made flowers and plants handicraft incrustation, makes the hour glass wind-drift sand the ideal material!
