As for the new partners, I believe that they have encountered similar problems, such as uneven luminescence, dots and shadows in the resin luminous words. In fact, this problem is very simple to say. If there is no leveling agent, the surface becomes thin, and the light is emitted directly from the light source, people can see through the bottom and display the light.
Let's take a look at the lanterns with Chinese characteristics. If you cover a layer of paper, the effect of light will come out. Therefore, in the production, we should first consider the distance between the light source and the surface, second, we should consider the density of the lamp, and third, we should consider adding leveling agent or light diffusion agent, and control the amount to change the light diffusion effect.
We are saying that we can add aluminum powder instead of adding it. For this reason, we are going to correct it. Generally speaking, ordinary people don't know about the optical properties and optical knowledge of materials, such as transmittance and refractive index. We don't have that method to control the appearance of shadows and uneven luminescence. So we'd better buy some back. As for how to add and how much to add, we can figure out by ourselves and practice. So we have always stressed that this thing is also technical work, practice makes perfect.
In addition, the following three points should be reiterated:
(1) It is suggested to pour in two times. The first time, diffusion agent or light guide agent should be added (in fact, the principles of these two things are similar, one is paste, the other is powder, the powder is cheaper). The initial resin amount is 1 / 31 / 3 of the total amount.
(2) Pigment should be added in place, because less can't block the light, so I said, to make the light transparent, it should be thin, but if the light is thin, the light will pass through the head, which is equivalent to that there is no paper for the lantern. Therefore, if you want to have a good effect, no problem, we must grasp how to make this paper, which is very important. Therefore, the front is divided into two pouring is also considered in this way (the second time without pigment).
(3) Main points: it is recommended to pour twice, add leveling agent and pigment again (for the first time) and thin, and practice more.
The above is about the reason why the resin luminous characters appear uneven. Do you understand? If you want to know more, please click our Jinan luminous character production Official website.
