Pultrusion Process, hollow structure
Performance: without breakdown under 1800 kv high voltage, surface
spraying RTV vulcanization silicone rubber, with excellent
antifouling performance, connected end to end as a circle.
Application of FRP sound-absorbing cover
Applied to reactive power industry and urban elevated road; The
highway; High-speed railway; Urban expressway. The subway tunnel
engineering; Bridge project; The airport sound barriers and sound
barriers and other noise reduction barrier project in residential
Main technical parameters
1,The average amount of sound insulation; P 31 db (1/3 octave, 125
hz - 4000 hz).
2,Absorption coefficient; Acuity 0.85 (1/3 octave, 125 hz - 4000
3,The noise reduction effect; 12 db (A) or higher.
Feature of FRP sound-absorbing cover :
1.Corrosion resistance and stable chemical properties
2.Sound insulation quantity can reach more than 31 db and
absorption coefficient; The noise reduction coefficient of the NRC
acuity 0.8 can meet the requirements of a variety of noise
3.Strong and durable; High strength, the flexural bearing capacity
of acuity 5.29 KN /m2; Out of shape not easily; Long service life.
4.Light weight (weight 16 kg /m2) or less sound barriers can reduce
the strength of the foundation and pillar design requirement and
bring convenient installation.
5.Screen in the rain, the natural conditions, such as the sun
sinks, agglomerate, not easy damage, good weatherability. Products
have anti-theft function; The late maintenance convenient and does
not change color, easy to clean.
6.Products according to customer demand customize various color and
