Comparison of advantages and disadvantages of PC solid sheet and glass for lighting building materials
Sun board PC endurance board and glass are all common light building materials on the market. Therefore, PC endurance board is often compared with glass. How do you choose PC board light top?
The weight of the pc endurance plate is about 1/3 of the same specification glass, and the price is about 2-3 times. For example, if the pc strength plate has a thickness of 4.5mm, the glass thickness of about 10mm can be purchased at the same price. Because of its light weight relative to glass, and its flexible nature, pc Nacelle can be used in narrow spaces and special angles. It can be used in all kinds of spaces and is convenient for construction. At the same thickness, the pc-resistant plate has a better soundproofing effect at higher frequencies than glass.
Today, glass also has special-purpose glass such as toughened glass. The risk of glass construction is also much lower than before. However, even tempered glass has the risk of chipping of the entire glass during strong winds and earthquakes, even if it is special glass, broken pieces. Cracking can still cause harm. On the contrary, pc stamina boards have no such problems. The strength of pc stamina boards is 250 times that of ordinary glass, and it is also 50-100 times stronger than tempered glass. The toughness of the pc endurance plate is strong, even if it is struck with a hammer, there is no danger of fragmentation. The permissible impact strength per unit area is 91kgf-cm/cm of notch, and the compressive strength is 739kgf/cm^2 for earthquakes, The areas with strong winds are really good building materials.
When glass is used as a building material, it is often used in colloidal cooperation to combine two thin glasses into one thicker glass. The middle film, after prolonged exposure to the sun, may cause embrittlement and pose a safety problem. Glass is often weather-resistant and durable, and there is no in-depth knowledge of the problem that glass may cause fragmentation after prolonged exposure to the sun. In addition, when glass is used in building materials, it often uses silicone and other adhesive materials as caulking and bonding adhesives. However, in the case of silicon, for example, silicon lican will harden and embrittle for a long time, resulting in insufficient adhesion of the adhesive area. Under the impact of external forces or strong winds, it is easy to cause glass fragmentation and cause problems such as casualties or loss of assets. Taking the coastal areas as an example, the wind power received by the buildings is stronger than that of the ones receiving typhoon, and glass is rarely used as building materials. In Japan, for example, because of the strong earthquakes that often occur in Japan, buildings often use pc Nacelle for their light building materials.
As the cheaper PC endurance panels in the market often use recycled materials to reduce the production cost and reduce the price to compete, their neglect of quality makes ordinary people feel that they are likely to cause yellowing and endurance. The use of high-quality new raw materials produced by the pc Nai Liban, can ensure durable use for more than 10 years.
Compared with glass, pc board has a larger coefficient of thermal expansion, which is about three to six times that of glass. Glass is more brittle but its hardness is higher than that of pc board, and it is less likely to scratch during transportation. Matte and other issues caused by scratches, compared with the pc board has its own advantages and disadvantages. The surface of the glass is more subtle, teaching is not easy to absorb dust.
The light transmittance is about 5% less than that of the glass, so the emphasis should be on the landscape rather than the safety of the sights and landscapes. The glass is the choice for most people, but the pc board must emphasize the safe area, such as the lighting balcony, garage Where people often go in or people are in the area below, pc board is the best choice for construction
