一、阻性隔音屏

　　阻性隔音屏面板背板侧板构成一个封闭的箱式结构，形成一个模块化单元。面板为穿孔率为25%的镀锌板，背板和侧板为不穿孔的镀锌板，(从美观角度考虑，也可用彩色钢板)两层之间填充的为防潮降噪的离心玻璃棉，吸声材料用聚氟乙烯薄膜覆盖。立柱为H型钢，柱间距2m。立柱插于钢筋混凝土的基础内，将标准板H型钢之间，用紧固件加以固定，安装，维修，更换极为简便。

　　二、普通透明隔音屏

　　普通透明隔音屏采用透明的聚碳酸酯板(又称PC板)，因为是透明，隔声屏障的精悍感较好，比较容易融入周围的环境，颜色可选。

　　三、微孔透明隔音屏

　　微孔隔音屏有2层，它应了微孔吸声原理，在1层聚碳酸酯板上穿许多直径为0.8mm的小孔，穿孔率为1%。另一层聚碳酸酯版不穿孔，;两层板之间的间距为100mm，他相当于一个单层微孔牺牲结构，解决了吸声和透明之间的矛盾。由于声波的作用，微孔并不会被灰尘堵塞。

　　四、复合式隔音屏

　　复合式隔声屏障兼有透明和不透明隔音屏的有点。他一半是阻性隔音屏，另一半是透明隔音屏，由一与二复而成以上4中隔声屏障的高度可以根据设计要求自由组合，亦可根据客户的要求定制隔音屏。

A, resistive sound insulation screen

Resistive soundproof panel Backplane side panels form a closed box structure, forming a modular unit. The panel is galvanized sheet with a perforation rate of 25%, the back plate and side plate are galvanized sheet without perforation, (for aesthetic consideration, color steel plate can also be used) the centrifugal glass wool filled between the two layers is moisture-proof and noise-reducing, and the sound absorption material is covered with polyfluoroethylene film. The columns are H-shaped steel, and the column spacing is 2m. The column is inserted into the reinforced concrete foundation, and is fixed, installed, maintained and replaced by fasteners between standard h-beams.

Two, ordinary transparent sound insulation screen

Ordinary transparent sound insulation screen uses transparent polycarbonate board (also known as PC board), because it is transparent, sound insulation barrier sense is better, easier to blend into the surrounding environment, color optional.

Three, microporous transparent sound insulation screen

Microporous sound insulation screen has 2 layers, it should be the principle of microporous sound absorption, in 1 layer of polycarbonate board through many holes with a diameter of 0.8mm, the perforation rate is 1%. Another layer of polycarbonate plate is not perforated,; The spacing between the two layers is 100mm, which is equivalent to a single-layer microporous sacrificial structure, which solves the contradiction between sound absorption and transparency. Thanks to sound waves, the pores don't get clogged with dust.

Four, compound sound insulation screen

Compound type separates sound barrier both transparent and opaque sound insulation screen have a bit. Half of him is a resistive sound insulation screen, the other half is transparent sound insulation screen, composed of one and two complex and the height of the above 4 sound insulation barrier can be combined freely according to the design requirements, can also be customized according to the requirements of the customer sound insulation screen.
