Luminous toys are a kind of light that can be used for children to play with, and the color is also colorful. In fact, the luminous toy is the use of the injection of luminous powder, so that the toy emits beautiful light at night, then what are the things that need attention when the luminous toy luminous powder is used in the injection molding method? The following small series will introduce you to everyone.
1。 Ingredients: firstly scale the light-absorbing light-emitting luminous powder (the content is about 2 to 10%), add a small amount of diffusion oil (paraffin oil, white oil) and stir into a paste, then add the raw material to stir。 Add the color powder and stir well。 The time should not be too long to avoid the precipitation of long afterglow luminous powder。 Pay attention to the strong night metal powder rubbing with iron and other heavy metals, which will make the raw materials black。 The materials that can be used are: PP, PE, PVC, PU, PS, ABS, TPR, EVA, PMMA, nylon, etc。 The more transparent the plastic material, the better the illuminating effect。 The toner should be as fluorescent powder as possible。 The less the better, the better。
2. The temperature of the injection molding machine is lowered, and it can be injected. The time in the injection molding machine should not be too long to avoid burning.
3, injection molding machine: different machine injection products, there are also differences, new machines and old machines, domestic machines and imported machines, which need to be slowly solved in the solution.
4, luminous powder: luminous powder in the injection molding for various reasons, injection molding technology, injection molding machines, may cause blackening, can be determined according to their own circumstances。
The above is about the night light toy luminous powder need to pay attention to the injection molding, I hope to help everyone。
