50um UV resistant polycarbonate sound barrier  

 

Between the sound source and receiver inserts a facilities, makes the sound waves spread has a significant additional damping, so as to abate the noise effect of the receiver in a certain area. This facility is called noise barrier. According to the application environment of noise barrier, divided into traffic noise barriers and equipment noise attenuation of noise barriers, industrial factory boundary noise barriers.

A. Special mechanical properties of polycarbonate solid sheet sound barriers

1. Impact strength: Polycarbonate solid sheet has excellent shock resistance, it is 250 times higher than the traditional glass, 30 times higher than acrylic.

2. Good tensile strength, Polycarbonate solid sheet has good heat resistance, even at 120 ℃, its tensile strength is still up to 350 KGF/cm2.
3. Bending strength: Polycarbonate solid sheet has excellent buckling resistance, even if the bending Angle of 90, it can be still not broken.
4. Fatigue and creep resistance: the creep resistance of Polycarbonate solid sheet is one of the best in the thermoplastic. Even if at high temperature, its creep resistance is still very small.

B. The thermal performance of special Polycarbonate solid sheet sound barrier
1. Melting temperature: Polycarbonate solid sheet melts in 135 ℃, can continuous use in 120 ℃.
2. Linear expansion coefficient: linear expansion coefficient of 7 x 10-5 cm/cm / ℃ is smaller in the plastic.
3. Brittle temperature: brittle temperature of Polycarbonate solid sheet is minus 40 ℃, the minimum temperature for continuous using is minus 30 ℃, is incomparable by the general plastic.
4. Combustibility: Polycarbonate solid sheet belongs to one of flame retardant self-extinguishing plastics, it does not produce poisonous gas in high temperature heating.
5. Thermal conductivity: thermal conductivity of Polycarbonate solid sheet is sane as the general plastic, is about a quarter of the glass, 1/300 of the iron, 1/1000 of aluminum, 1/2000 of the copper, is one of the good performance of heat preservation material.

C. Optical properties of special Polycarbonate solid sheet sound barriers
1. Light transmittance: the light transmittance of Polycarbonate solid sheet is between 85% to 90% same as the glass.
2. Weather resistance: general Polycarbonate solid sheet exposes outside in a long-term, easy cause yellowing by ultraviolet radiation and surface degradation. Polycarbonate solid sheet surface coats a UV resistance layer, even if exposed outside in a long-term, its optical and mechanical performance have no significant changes.

D. Chemical resistance of Polycarbonate solid sheet sound barriers

Polycarbonate has good resistance performance for weak acid, weak alkali and alcohol at normal temperature, but has a bit poor resistance performance for strong acid and alkali, benzene, chlorinated hydrocarbons and esters, and prones to dissolved, swelling or decomposed phenomenon. Because its chemical resistance relates to temperature, internal residual stress size and length of exposure, so should pay special attention before using.

E. Light weight of Polycarbonate solid sheet noise barrier

Under the same thickness and area, the weight of Polycarbonate solid sheet is only about half of the glass, so can save the handling and the difficulty of the construction noise barrier.

F. Sound insulation performance of Polycarbonate solid sheet sound barriers

Sound insulation effect of Polycarbonate solid sheet is higher than glass 3-4 db, transparent insulation material is the first choice of noise barriers.
