With the call of the government to vigorously promote the city lighting, at present, the advertising front word is mainly light-emitting words. At present, the luminous words mainly include acrylic light-emitting words, plastic absorbing luminous words, resin luminous words, etc. resin luminous words are loved by the majority of merchants due to their multiple advantages of low cost and good effect. This paper introduces some matters needing attention in the production of resin light-emitting words Let's take a look.
1. Material selection
According to the actual production of luminous words, unsaturated polyester resin, epoxy resin and polyurethane can be selected. Generally speaking, the above three kinds of resins are commonly used and more mature. If other materials are also used, of course, it is better. As far as the overall production process and technology are concerned, other resin materials do not seem to be suitable or easy to use. In terms of making full body luminous large characters, it is better to use unsaturated polyester resin, which is cheap and quick to form. If you want to make fine small characters such as signs, and want to be used as a whole for pouring and sealing, it is better to use epoxy resin. The shrinkage and brittleness of unsaturated polyester resin become unfavorable factors. Polyurethane can also be used for pouring font, but it is soft The adjustment of hardness has become a difficult point for users, and the supply of various supporting materials is not enough, and the bonding with mold base material is not as good as epoxy resin. Epoxy resin only has poor adhesion to several polyolefin plastics, so it needs to do some technical treatment, so it can be said that the adaptability of all-purpose adhesive is very good.
In any case, the transparency of the resin must be better, or we have to use more lights to waste. What's more, it's best not to have any color? Otherwise, the color can be well blended, trouble. What's more, the resin has to be a bit tough, not all like glass products, hardness is not low, but should be handled with care.
Selection of forming process
Make a large character, from tens of centimeters to a few meters, and generally not large-scale mass production, it is not suitable to use mold. Otherwise, most of the cost will be spent on the mold. In this way, we have to make lath first, and then fold it into shape, which is more feasible. The so-called folding molding, that is to surround the edge, surround a word border, according to it to cover the back cover to make the shape. But the key is that the resin can be bent before it is fully cured. It's just that flexibility is different. Stiffness is different. The variety of resin, the proportion of raw materials, and even the curing temperature, time and degree, etc. This heat can only be mastered by experience. To make smaller characters, most of them are below tens of centimeters. Smaller words or signs are often produced in batches, and the appearance is required to be exquisite and beautiful.
Nowadays, the conventional product is to make a model shell with single side opening of font or logo, which is usually opaque. The light emitting body of the light bulb inside is filled with resin. In this way, the whole word will come out, and the front will shine. Plus a variety of effects are quite beautiful, of course, the word is solid single-sided luminous. The difficulty of making three-sided transparent small characters is the problem of uniform light. Of course, with some efforts, from the production process to the application of uniform light scattering agent, this problem can be solved eventually.
3. Selection of light source
When choosing the light source, you should consider that it can be put into the words, and it has the same brightness, so that it can be used for a period of time. It's better to lower the heat dissipation and power consumption? Now LED is widely used. Different LEDs have different light intensity, power consumption, shape and divergence angle. Of course, including the good modules, the quality is not the same,resin luminous word production considerations and solutions, the price is also very different.
