How to avoid the glow in the dark powder in blackening?
Several problems should be paid more attention to the long-lasting glow powder when it is applied to injection molding.
The problem that long-lasting glow in the dark powder is used in injection molding is mainly because the glow powder is relatively hard, and the phenomenon of blackening caused by friction with the screw, how to avoid this phenomenon?
1.The first is to use a finer particle size and a softer glow powder. iSuoChem supply softer powder, faster absorption, finer grain size and high brightness of glowing pigment.
2.When mixing again, try to choose manual mixing and avoid using machine mixing. The diffusion oil is first added to the raw material and stirred for one minute, then the glow powder is added and stirred for one minute, and then the pigment is added and stirred for two minutes.
3.The injection molding machine should be cleaned and the temperature of the front section should be raised as much as possible during the process. The temperature and pressure of the rear section should be lowered as much as possible on the basis of the finished product. The time of the glow powder in the injection molding machine should not be too long to avoid burning.
There are also differences in the injection products of different machines, new machines and old machines, domestic machines and imported machines, which need to be solved in the slow debugging. The machine adopts the old injection molding machine with short screw as far as possible (the machine head within 0.8m is generally recommended) to make luminous products, and the effect is relatively better.
4.Various reasons for long-lasting glow powder in injection molding: injection molding technology, injection molding machines, and the temperature of the dissolved materials may cause blackening.
5.The ratio of luminous materials to plastic materials is generally 3%-10%. It can adjust the proportion according to the depth of product, the principle of less light color and more dark color, luminous brightness requirements and cost accounting, but the proportion should not exceed 10%.
