Phosphorus injection molding

How to compare the luminous powder?

A: Place the luminous powder on the hard board under the light, or 5-30 minutes under sunlight and natural light to absorb the light saturation (well to compare the light, so you can purify the luminous powder. to see), and then along with the hard The board can be seen in the dark to see the glow effect. Luminous bright (bright) powder can be illuminated in the dark for 1-20 hours, and luminous life can be absorbed and illuminated several times for more than 20 years. Includes brightness and long-distance. time on yellow green light, blue-green light and blue sky luminous powder, and are widely used. .

Initially, the luminous powder injection method

1. The woody injection molding (bright) special luminous powder is suitable for all kinds of performance rubber material (PP, ABS, PC, PVC ...) It has good luminous effect with transparent plastic, and translucent plastic can have better effect luminous also get. In color, do not add too much toner in the rubber, or it will reduce the light of the night light greatly. For products with deep color, the brightness of the night light should increase the proportion of luminous powder, use luminous powder. bright color (bright) directly. Mixed with transparent rubber, color powder need not be added;

2, the extra content: 1 kg plastic material: luminous powder between 20 grams and 200 grams (plus 40 to 80 grams of more generally), in this area, the amount of luminous powders is more and brighter, the amount is extra too small to spread. Uniform, which means that some products do not emit light or have black spots when emitting light;

3, the selection of rubber materials: water mouth content plus luminous powder injection is easy to black, it is recommended to use new materials; the rubber in the rubber is also easy to black, so moderate drying before injection;

4, choose injection molding machine: injection molding machine to be clean, use a short barrel, reduce injection time, quickly forward and quickly, so as not to burn black, injection molding machine is different to make a difference, if injection black luminous products the injection molding machine can be changed to disinfect excellent results;

5, mixed method: add an appropriate amount of white mineral oil and rubber compound with a mixture evenly (avoid the mineral oil viscosity to avoid the base of the light sinking of the night), and then add the luminous powder to the percentage of the mixture, you can, (remember not to use metal items to vigorously stir, otherwise it turns black) (try to reduce the injection temperature, select low temperature of the product to dump the luminous products), and make a luminous plastic product after injection molding .

Secondly, use luminous powder in rubber, silica gel

    Adding ratio: 1 kg of silicone rubber: between 10 and 200 g of luminous powder. The luminous powder size is brighter in this area If the additive size is too small, the spread is very uneven, and resulting some products do not emit light or black spots when light is emitted. ;

Luminous powder is very easy to use in TPU and TPR. As long as the high temperature rubber is added, the luminous powder is applied proportionally and evenly.

The luminous powder is good with transparent silicone rubber inside the brightness, if you want to add color glue, try adding less, the product should add a more luminous powder color. Use of luminous powder bright color (bright) can be placed directly with transparent silicone rubber, without adding color glue and color light products further.

Precautions use successful luminous powders (bright): luminous powder more important, pay attention to mix when using. Luminous powder should be stored in a ventilated environment, dry, pay attention to moisture, use a plastic bag to seal the unused luminescent powder at one time.
