一、阻性隔音屏

　　阻性隔音屏麵板背板側板構成（chéng）一個封（fēng）閉的箱（xiāng）式結構，形成一個模塊化單元（yuán）。麵板為穿孔率（lǜ）為25%的鍍（dù）鋅（xīn）板（bǎn），背板（bǎn）和側（cè）板為不穿孔的鍍鋅板，(從美觀角度考慮，也可（kě）用彩色鋼（gāng）板)兩層（céng）之間填充的為防潮降噪的離心玻璃棉，吸（xī）聲（shēng）材料用聚氟乙烯薄膜覆蓋。立柱為H型鋼，柱間距2m。立（lì）柱（zhù）插於鋼筋混凝土的基礎內，將標準板H型鋼之（zhī）間，用緊固件（jiàn）加以（yǐ）固定，安裝，維修，更（gèng）換極為簡便。

　　二、普通透明隔音屏

　　普（pǔ）通透明隔音屏采用（yòng）透明的聚碳酸酯板（bǎn）(又（yòu）稱PC板)，因（yīn）為是透明，隔聲屏障的精悍感較好，比較容易融入周圍的（de）環境，顏色可選。

　　三、微孔透明隔音屏

　　微孔隔音屏有2層，它應了微孔吸聲原理，在1層聚碳酸酯板上穿許多直徑為0.8mm的小孔，穿孔率為1%。另一層聚碳酸酯版不（bú）穿（chuān）孔，;兩（liǎng）層板之間的間距為100mm，他相當於一個（gè）單層微孔犧牲結構，解決了（le）吸聲和透（tòu）明之間的（de）矛盾（dùn）。由（yóu）於聲波（bō）的作用，微孔並不會被灰塵堵塞。

　　四、複合式隔音屏

　　複（fù）合式隔（gé）聲屏障兼有透（tòu）明和不透明隔音屏的有點。他一半是阻性隔音屏（píng），另一半是透明隔音屏，由（yóu）一與二複而成以上4中隔（gé）聲（shēng）屏（píng）障的高度可以根據設計要（yào）求自（zì）由組合，亦可根據客戶的要求定製隔音屏。

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.
