Yumingjie Technology - the main pigment, reflective powder, copper powder, luminous powder, phosphor, pearl powder, aluminum silver paste, glitter powder and other reflective powder is produced from a glass microbead powder material, it is Production of reflective fabrics, reflective foils, reflective coatings, reflective signs, advertising materials, apparel materials, standard stadium tracks, shoes and hats, school bags, water and land life-saving supplies, and other core materials, which have the characteristics of retroreflective This results in a strong retroreflective effect, without the need for external power supply, can be widely used in roads, ports, mines, firefighting and other fields, as a safety sign, greatly improving the safety of users.
Yu Mingjie reflective powder characteristics:
1. Color: white / gray
2. Refractive index: ND ≥ 1.90, ND ≥ 1.93, ND ≥ 2.2
3. Chemical composition: SiO2, CaO, Na2O, Tio2, Bao, etc.
4. Mesh: Available from 100 mesh to 500 mesh
5. Transparency: ≥95%
6. Roundness: ≥93%
7. High anti-oxidation, high temperature resistance and excellent reflection effect
[How to use]: (Screen printing method)
Water-based silk screen method: The reflective powder is directly added to the transparent pulp, and the additives are added appropriately, and the printing can be printed and printed.
Water-based silk screen method 2: The reflective powder is directly added to the gold-silver powder binder, and the additive is added appropriately, and the uniformity can be printed and printed.
Water-based silk screen method 3: Reflective powder is directly added to the water-based "reflective powder special ink", adding 0.5-2% water-based special effect catalyst, evenly adjusted to print and print. (This method works well)
Oily silk screen printing method 1: The reflective powder is directly added to the varnish, adjusted evenly, and the additives are added appropriately, and the uniformity can be printed and printed. (This method works well)
Oily silk screen method 2: Reflective powder is directly added to the ink/paint to make reflective ink, silk screen or brush applied to fabric, license plate, house number, signage, traffic signs.
1. When printing, the thickness of the printed adhesive layer should be thin, preferably from 30 micrometers to 50 micrometers, to ensure that the reflective powder can be semi-exposed on the surface to produce a reflective effect.
2. It is possible to obtain various reflection effects by using particle sizes of different thickness depending on the application.
The above method of use is simple and convenient to operate and easy to grasp.
[Construction method]: (spraying method)
1. Thoroughly remove oil, water and dust from the surface of the substrate before construction, while keeping the working surface dry.
2. Spray the primer on the reflective primer first, and then spray the reflective finish after the reflective primer is dry. For cement surface construction, it is recommended to spray two layers of reflective primer for better effect. Stir the paint thoroughly before spraying the topcoat. Stir constantly during construction.
3. It is recommended to use the W-71 type spray gun (spray ¢ 1.50 mm), the primer using the spray gun pressure of 2.0Kg/cm2, and the top paint spray gun pressure of about 3.0kg/cm2.
4. The coating thickness of the reflective topcoat, in the case of ensuring the tinting strength, the thin and uniform coating has the best reflective effect, one molding. The paint film should not be too thick and have a thickness of about 20 microns, otherwise the effect will be poor.
5. The spray gun and surface need to be kept at 18cm, the spray gun angle is 45°, and the paint film layer should be thin, which is good. For unknown substrates, try a small area in advance.
6. Clean the spray tool with thinner after construction.
7. Do not work under bad weather such as rain, fog, snow, etc., which will affect the fastness.
[Note]:
1. Clean the construction surface before use, the surface is free of oil and dry.
2. The reflective primer and reflective topcoat must be evenly mixed before construction; stirring should be carried out during the painting process to prevent the precipitation of reflective powder.
