PRODUCT DESCRIPTION

Classification of noise barriers: noise barriers are classified according to their materials, mainly including: all-metal noise barriers, all-glass fiber reinforced plastic noise barriers, endurance board (PC) full-transparent noise barriers, high-strength cement noise barriers, cement sawdust noise barriers, etc.;

The noise barrier is a shielding structure between the sound source and the receiver, which is mainly used to block the transmission of direct sound. It is a sound insulation facility.

According to the application environment of noise barriers, noise barriers are divided into traffic noise barriers, equipment noise attenuation noise barriers, and industrial boundary noise barriers.

Noise barriers can be divided into the following categories according to different uses: railway noise barriers, highway noise barriers, urban landscape noise barriers, residential noise barriers, etc.

Types of Noise Barriers

1. Resistive noise barrier: The resistive noise barrier consists of a front panel, a rear panel and a side panel to form a closed box structure, forming a modular unit. The front plate is a galvanized steel sheet with a perforation rate of 25%, and the rear and side plates are non-perforated galvanized steel sheets (from an aesthetic point of view, colored steel sheets can also be used). Moisture-proof centrifugal glass wool board is filled between the two layers, and the sound-absorbing material is covered with polyvinyl fluoride film. The column is 12# I-beam, and the column spacing is 2m. The columns are inserted into the reinforced concrete foundation. Insert the standard plate between the I-beams and fix them with fasteners, installation, maintenance and replacement are extremely easy.

2. Ordinary transparent noise barriers: ordinary transparent noise barriers use transparent polycarbonate sheets (also known as PC boards), because they are transparent, the sound barriers have a better sense of landscape and are easier to dissolve into the surrounding environment. Color optional.

3. Micro-porous plate transparent sound insulation barrier: The micro-porous plate transparent sound insulation barrier has 2 layers. It applies the principle of micro-porous sound absorption. A number of small holes with a diameter of 0.8mm are penetrated on the 1-layer polycarbonate plate, and the perforation rate is 1%. . The other layer of polycarbonate sheet is not perforated, and the spacing between the two layers is 100mm. It is equivalent to a single-layer microporous sound absorption structure, which solves the contradiction between sound absorption and transparency. Thanks to the sound waves, the pores are not blocked by dust.

4. Composite noise barrier: Composite noise barrier has the advantages of both transparent and opaque noise barriers. Half of it is a resistive sound barrier, and the other half is a transparent sound barrier. It is composed of one and two. The height of the above four kinds of sound barriers can be freely combined according to the design requirements, and the road screen can also be customized according to customer requirements.

Application of noise barriers: At present, noise barriers are mainly used for sound insulation and noise reduction in transportation municipal facilities such as highways, elevated composite roads, urban light rail subways, etc., to control the impact of traffic noise on nearby urban areas, and can also be used in factories and other noise sources. sound insulation and noise reduction.
