How to use luminous powder in injection silicone rubber?

First, the successful luminous powder is used in plastic injection material silicone plastic injection

When long-term luminous powder is used for molding injection, the ratio of luminous materials to plastic materials is usually about 2% -10% (25 kg of material plus one kilogram of long shiny shiny), by color of the product. The depth is light, the color is less light, and the deep color is more important. First, when mixing, add the diffuse oil to the raw material for a minute first, then add the luminous material for one minute, then add the color powder for two minutes. exciting time to be too long. Iron, too long, will cover the raw material. Secondly, the injection molding machine should be cleaned, the temperature should be adjusted to a lower level, and it can be injected. The time in the injection molding machine should not be too long to burn. to avoid, and the injection products at different machines are also different. Domestic machines and imported machines, which need to be resolved slowly. Once again, there are certain requirements for the development of luminous materials. Light storage powders acting long may cause ducting due to various reasons such as injection molding technology, injection molding machines, and molten material temperature. . Black injection molding performance was better.

Secondly, use successful luminous powder on ceramic glass and precautions

1. First, mix the luminous powder with the low-temperature ceramic glaze powder (luminous powder is 40% by weight) and the ratio of water by weight t

The ratio of 1: 0.6 milled into a ball mill for 20 minutes to make slurry glaze. A glaze layer of 200-400 μm is created on the white body of green ceramic by glass, glazing, glazing, etc.. spraying and drying at 800-960. At a temperature of 35 degrees, it can be burned rapidly in 35 to 50 minutes, and can be made into a glazed tile product inside the wall.

2. The Luminous Xingsheng Powder and the low-temperature ceramic glaze powder are mixed uniformly (the luminous powder represents 30-40% by weight) and mixed with appropriate size of screen printing inks to prepare slurry for screen printing. A luminous pattern was created by printing a screen on luminous glass on the white glass layer of the uncultivated floor tile (80 to 120 mesh for the screen). On the surface of the pattern, rinse a layer of transparent glass. It is quickly lit in 35 to 45 minutes at a temperature of 850 to 960 degrees. It can be made in luminous pattern tile products.

3. First, make the luminous powder to mix the low-temperature ceramic glaze powder (the luminous powder accounts for 30-40% by weight) and mix with the appropriate oil screen printing to prepare the slurry for screen printing. Use wire mesh on the luminous pattern, make transparent glaze powder dry to stack, and fire quickly at 40 to 950 degrees for 40 to 50 minutes. A luminous pattern is formed with a convex effect. The wall inside a luminous pattern is decorated with glazed tiles.

Luminous powder note:

(1) Avoid strong friction between the luminous powder and the metal objects, otherwise it will affect the luminous effect. Xingsheng luminous powder particle size is usually 160-300 mesh or 200-400 mesh.

(2) If the glaze by arrangement, add 2 to 4% of the turmeric soil to increase the possibility of the glaze slurry.

(3) Select the low-temperature glaze that matches the white porcelain to control the temperature and time. If the temperature is too high, the burning time will affect the brightness.
