The purpose of the invention is to provide the application of luminous pattern baking paper in making ceramic building materials and daily articles. The invention adds luminous powder sold on [...]

Conversion of luminous powder,phosphor into nanometer, micron and mesh unit

1 cm (cm)=10-2m =10 mm (mm); 1 mm (mm)=10-3m =1000 microns (um); (3-5 micron um noctilucent powder = 0.003mm noctilucent powder) 1 micron (um)=10-6m=1000 nanometers (nm); (3-5 micron um noctilucent powder = 3000nm noctilucent powder) 1 nanometer =10-9m [Virus size about 100 nanometers Angstrom (Ao) = 10-10 m; One femtometer (FM) = 10 to 15 m Nanometer (nm)= [10 to the -7 to the -9 meters] = size of fineness, about 180,000 mesh ~ 18 million mesh unit conversion. Micron (um)= [10 to the -6 [...]

Uv fluorescent ink product introduction

Ultraviolet fluorescent ink is one of the most mature anti – counterfeiting inks in the market, in the ink to add the corresponding visible fluorescent compounds and made. The ink is printed with a fluorescent color that can be excited by ultraviolet light at 365nm (long wave) or 254nm (short wave) wavelengths. According to the different excitation light source, can be divided into long wave fluorescent ink, short wave fluorescent ink and double band fluorescent ink. According to the form [...]

The difference between long-acting luminous powder and short-acting luminous powder

Many friends should have used or heard of overnight luminous powder, but don’t know the difference between long-acting luminous powder and short-acting luminous powder. In order to make it easier for everyone to distinguish, choose the product that suits you for the following reasons Advantages and disadvantages of short-acting luminous powder 1. Zinc sulfide short-acting luminous powder has a short luminescence time, and it can only emit light for half an hour at most once it is stored. 2. Zinc sulfide short-acting [...]

Application scope and production status of reflective powder

Reflective powder: it is produced from a glass based powder material. Its main components are SiO2, CaO, Na2O,TiO2 and BaO. The product can be added directly to a coating or resin to give the product a retro-reflective effect and can be used on a variety of complex shaped surfaces. It is the production of reflective cloth, reflective film, reflective coating, reflective signage, advertising materials, clothing materials, standard racing track, shoes and hats, school bags, water, land and air life-saving [...]

Do you know about luminance and duration characteristics of glow in dark powder

About the brightness of luminous powder in the new customers often have doubts, clearly said that the manufacturer can be bright for 10 hours how to see half an hour, causing some unnecessary misunderstanding. The luminance of luminescent materials is usually measured in units of CD /m2(candela per square meter), while noctilucent powders are usually measured in units of MCD /m2(Millicandela per square meter). The midday sun reaches 10,000 to 100,000 CDS /m2, In the daytime, there are only 1000 ~ 5000cd/m2 [...]

Use method of reflective powder and reflective glass microbeads

Is the use of the reflective glass beads according to the actual needs of customers, according to different purposes, luminous intensity and the different requirements, in the actual production summary for its technical solutions, in the process of reflective glass beads is according to its luminous intensity, the length of the afterglow time, and determine its quality and cost, the following content is for reference only. Usage of reflective glass microbeads: Water-based screen printing method 1: Reflective glass beads can be directly [...]

Research status of fluorescent materials

1. Doping modification: Other ions are added to the traditional fluorescent materials to increase the conversion efficiency and enhance the fluorescence intensity. For example, add the sensitized Yb3+ ions to the fluorescent material. Yb3+ ion has a strong absorption cross section near 980nm, and only has two energy levels, so it will not lose the excitation light energy due to the up-conversion process. Therefore, it is an ideal sensitizer. In particular, lithium ions enhance the fluorescence of rare earth [...]

LED phosphors: a brief introduction of several phosphors

Ⅰ. Yellow phosphor powder Yellow Phosphors 1. Introduction: YAG phosphor is the fluorescent material of white LED. A blue light chip is coated with a layer of fluorescent substance, and a blue light LED is used to illuminate the fluorescent substance to generate complementary yellow light with blue light. Then the complementary yellow light and blue light are mixed with the principle of lens, and the white light required by the naked eye can be obtained. 2. Product Performance 2.1 The Appearance [...]
