(2) PC boards are mostly used in areas where safety must be emphasized, such as lighting balconies, garages and other places where people often go, and there are people in the lower area, so PC boards are the best choice for construction.
③ The light transmittance of tempered glass is about 5% higher than that of PC resistance board, so tempered glass can be selected to emphasize the landscape.
Tempered glass or resistor board has its own advantages and disadvantages. We will analyze them one by one:
? 1.PC resistant plate: Because of its light weight relative to glass and flexibility, it can be used in narrow spaces and special angles, and can be used in various spaces, which is convenient for construction. At the same thickness, the sound insulation effect of PC resistance plate is better than that of glass at high frequency.
Now the danger of glass building is much lower than before, but even tempered glass has the risk of breaking the whole glass in strong winds and earthquakes. Even special glass will still cause harm when broken. On the other hand, the PC resistor board does not have this problem. The strength of PC resistant plate is 250 times that of ordinary glass and 50- 100 times stronger than that of tempered glass. The PC resistance plate has strong toughness, so there is no danger of breaking even if it is struck with a hammer.
2. Tempered glass: Compared with glass, the thermal expansion coefficient of PC board is about three to six times that of glass. Although glass is easily broken, its hardness is higher than that of PC board, and there will be no problems such as scratches and scratches during transportation. Compared with PC board, PC board has its own advantages and disadvantages. But the glass with fine surface is not easy to absorb dust. The PC board on the market is easy to feel dirty after absorbing dust because of its large pores. Only a good quality board like Xinhai, such as UV board, has fine pores, so there is no such problem.
