Semi-metal plate transparent noise barrier

There are two main types of transparent materials currently used in highway noise barriers: one is polycarbonate board, also known as PC board; the other is acrylic board, also known as PMMA board. PC board is characterized by its high strength and moderate price, but its weather resistance is relatively poor. It is easy to age after being exposed to wind, sun and rain, and needs to be treated with UV protection; PMMA board is compared with PC board, although the price is * Expensive, but has the best light transmittance, chemical stability and weather resistance, not easy to age, easy to dye, and rich in color. The specific gravity of acrylic transparent sound barrier sheet is less than half of ordinary glass, and the resistance to fragmentation is several times higher. ; It has good insulation and mechanical strength; it has the corrosion resistance of glue gun to acid, alkali and salt; and it is easy to process. It can be bonded, sawed, planed, drilled, carved, polished, screen printed, sprayed Sand and other manual and mechanical processing, after heating, can be bent and molded into various products. Therefore, according to the customer's requirements on the cost, we select the corresponding transparent board.
