PVC word is also popular with customers, it has the following characteristics. First of all, it has low price and good manufacturing technology. You only need to mechanically carve out your own well-designed font. Handle the rough edge after cutting, such a process also fosters the price is not as good as other words.
Although the price is not high, but it does not mean that the quality is nothing. PVC material is light in weight, heat insulation, moisture-proof, anti-corrosion, flame retardant. In addition, it is firm and convenient for splicing and bonding. Also very welcome by the manufacturing staff, complex process intuitive shape, more than other words can lose the love of the market. From the construction point of view, PVC word manufacturing is convenient and fast, and the device is indirectly bonded to the scenery. In this way, it completely saves the efforts of one side.
We generally have such several kinds of appearance: flat edge light-emitting words, punching light-emitting words, plastic light-emitting words and so on. Let's share how to recognize these words.
Acrylic production is very difficult, the cost is also very high, so there are many low-cost substitutes in the market.
这些假冒的也被称为“亚克力”，其实他们是用的有 机板或者复合板(又称夹心板）。普通有 机板采用的是普通有 机玻璃裂解料加色素浇铸而成的，表面硬度低、易褪色、用细砂打磨后抛光效果差。复合板只有表面很薄的一层亚克力、中间是ABS塑料、使用中受热胀冷缩影响容易脱层的。
These fake ones are also called "acrylic". In fact, they are made of organic board or composite board (also known as sandwich board). Ordinary organic board is cast with ordinary organic glass cracking material and pigment. It has low surface hardness, easy to fade and poor polishing effect after grinding with fine sand. The composite board has only a very thin layer of acrylic on the surface, ABS plastic in the middle, and easy to be delaminated due to thermal expansion and cold shrinkage in use.
The true and false acrylic can be identified from the fine color difference and polishing effect of the plate section. In the process of making acrylic luminous characters, we should pay attention to the following points:
When making acrylic luminous characters, the voltage of LED module should be the same as that of switching power supply. Also to ensure that the card slot and blister bottom plate firmly stick, acrylic luminous words are generally used in outdoor installation, so there is sunlight, if not solid will cause falling off. The power cord should not be too long, as short as possible.
Only with high-quality acrylic can we make good acrylic luminous characters. There are all kinds of acrylic luminous characters on the market. Please carefully identify them.
