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 added to the water-based glue, uniform adjustment (can be appropriately added additives to enhance fastness), printing, printing.
Water-based silk-printing method 2:
Reflective glass beads can be directly added to the transparent pulp, uniform adjustment (can be appropriately added additives to enhance fastness), printing, printing.
Oily screen printing method 3:
Reflective glass beads can be directly added to the varnish, uniform adjustment (can be appropriately added additives to enhance fastness), printing, printing.
Oily screen printing method 4:
It can be directly added into the ink to make reflective ink, screen printing or brush to fabric or other items, easy to use and operate, easy to grasp. The amount added depends on how bright the reflection is.
Oil screen printing method 5:
First base coating printing paste — surface coating reflective paste — drying and curing reflective paste preparation: according to the amount, weigh reflective glass microbeads and adjust them into paste with solvent (cyclohexanone), then add them into transparent printing paste for uniform use. * When printing, the printing layer thickness to be thin, to 30 microns – 50 microns appropriate, to ensure that the reflective powder can be half dew on the surface, produce reflective effect. Can be used according to the purpose, the size of the diameter of different thickness, to achieve a variety of reflective effects. (Particle size is different, the better the reflective effect).
Spraying method 5:
1. Spray reflective primer and wait for reflective primer to dry before spraying reflective finish. If the cement surface construction, it is recommended to spray two layers of reflective primer effect better
2. It is recommended to use w-71 type spray gun (￠1.50mm nozzle). The primer shall use about 2.0kg /cm2 and the finish about 3.0kg/cm2
3. During construction, the spray gun and the surface should be kept 18cm, the spray gun Angle should be 45°, and the spray paint film layer should be thin to obtain a good effect. 4. Do not work in bad weather, such as rain, fog and snow, which will affect the fastness.
Principle of reflection: The reflective powder is used to reflect the light rays on the lens and other objects. It is refracted and then concentrated, and then reflected from the focus and refracted by the lens to return to the direction of the light source. Products with high refractive index glass beads back half surface aluminum as a backward reflector, has a strong regressive reflection performance, can be 80% of the light directly reflected back to the light source. The brightness of the reflection caused by the regression reflection enables the driver and the night operator with light source to see people and obstacles clearly at night or in poor vision, ensuring the safety of both parties.
Scope of application: reflective powder is the production of reflective fabric, reflective film, reflective ink, reflective paint, reflective signs, advertising materials, reflective clothing, standard field runway, shoes and hats, bags, with both life-saving supplies the core of the new optical functional composite materials such as raw materials, it has the characteristics of regression reflection and the resulting strong regression reflection effect, without power supply, can be widely used in roads, ports, mines, fire and other fields, as a safety sign, greatly increased the safety and reliability of the user; Widely used in screen printing, traffic signs, reflective leather, reflective materials and other fields.
