How to Identify the Quality of PC Sunshine Board？

Polycarbonate (PC for short) sheets have unique advantages such as light weight, high transparency, good impact resistance, temperature resistance, flame retardancy, sound insulation, heat insulation and good electrical insulation. It is a new type of building sheet that is popular and recognized in the current building materials market. It is widely used in the fields of construction, advertising, agriculture, manufacturing and decoration. Below. PC board manufacturers teach you how to distinguish the quality of PC sheets.

PC board manufacturers teach you how to distinguish the quality of PC sheets

1. Look at the raw materials

Whether it is PC sun panels or solid endurance boards, the raw materials have a direct impact on the color and service life of the product. PC board raw materials are divided into imported new materials, domestic new materials, and recycled materials. The quality of boards produced with different raw materials is different and the price is also different. When we buy, we must not be greedy for cheap prices and choose sun panels or solid endurance boards made of recycled materials. The performance of such boards is greatly reduced. At present, the high-quality raw materials selected by manufacturers are mainly imported new materials from foreign brands such as Bayer, Teijin, and LG Chemical, followed by domestic big-name new materials.

2. Look at the appearance

Generally, PC manufacturers such as polycarbonate sheets and solid boards can send free samples. You can observe the samples or conduct field visits to distinguish the quality with your naked eyes.

First, look at the transparency. When the sheet is facing the light, the light of a good sheet is very clear, without fogging and blurring, and without obvious impurities or pitting; then, look at the color. Polycarbonate sheets and endurance sheets with uniform and pure colors, without yellowing or darkening are the most ideal choices; finally, look at the surface. Polycarbonate sheets and endurance sheets are covered with protective films, so we need to check whether the protective films are intact and whether they are easy to fall off. Then, you can tear off the protective films of the samples to see whether the surface is flat and smooth, whether there are scratches, pits, unevenness, and observe whether the sheet has small bubbles, horizontal lines, wavy lines and other undesirable phenomena at a 45-degree angle.

3. Look at the UV layer

PC polycarbonate sheets, endurance sheets and other sheets have an anti-ultraviolet (UV) coating co-extruded on one side and anti-condensation treatment on the other side, integrating anti-ultraviolet, heat insulation and anti-fog droplet functions. It can block ultraviolet rays from passing through, and is suitable for protecting precious artworks and exhibits from ultraviolet damage and extending their service life. We can observe through a professional ultraviolet microscope, and illuminate the side of the PC solid board with a pure ultraviolet light source at an angle of 45°. Under the microscope, the UV layer will reflect ultraviolet rays and show a dark blue color, so the quality of the UV layer of the board can be observed intuitively. If there is no professional ultraviolet microscope, you can use a banknote detector lamp and RMB banknotes to conduct a simple ultraviolet defense experiment. As we all know, there is an anti-counterfeiting mark on the RMB banknotes, which will show a golden fluorescent reaction under the irradiation of ultraviolet light. We can put a PC solid board between the ultraviolet light source and the RMB banknotes. If there is no golden fluorescent reaction on the banknotes, it proves that the board has the ability to prevent ultraviolet rays.

Conclusion

In addition to the above methods, we can also learn about the brand and manufacturer of the product. Generally speaking, the product quality of some old manufacturers and well-known brands is more trustworthy. In addition, you can also look at the product inspection report provided by the manufacturer. Regular manufacturers will send their products to third-party institutions for inspection regularly.
