一、阻性隔（gé）音屏

　　阻性隔音屏麵板背板側板構成一個封閉的箱式（shì）結構，形成一個模（mó）塊化單元。麵板為穿孔率為25%的鍍鋅板，背板和側板為不穿孔的鍍鋅板，(從（cóng）美觀角度考慮，也可（kě）用彩色鋼板)兩層之間填充的為防潮降噪的離心玻璃棉，吸聲材料用聚（jù）氟乙烯薄膜覆（fù）蓋。立柱為H型鋼，柱間距2m。立柱插於鋼筋混凝土的基（jī）礎內，將（jiāng）標準板H型鋼之間，用緊固件加以（yǐ）固定，安裝，維修，更換極為簡便。

　　二、普通透明隔音屏

　　普通透明隔音（yīn）屏采用透明的聚碳酸酯板（bǎn）(又稱PC板)，因為是透明，隔聲（shēng）屏障的精悍感較好，比較容易融入周圍的環境，顏色可選。

　　三、微孔透明（míng）隔音屏

　　微孔隔音屏有2層，它應了微孔吸聲原理，在（zài）1層聚碳酸酯（zhǐ）板上穿許多直徑為0.8mm的小孔，穿孔（kǒng）率為1%。另一層（céng）聚（jù）碳酸酯版不穿孔，;兩（liǎng）層板之間（jiān）的間距為100mm，他相當於（yú）一個單層微孔犧牲結構，解決了吸聲和透明之間的矛盾。由於聲波的作用（yòng），微孔並不會被灰塵（chén）堵塞。

　　四、複合式隔音（yīn）屏

　　複合式隔聲屏障兼有透明和不透（tòu）明隔音屏的（de）有點。他一半是（shì）阻性隔音屏，另（lìng）一半是（shì）透明隔（gé）音屏，由一與二複而（ér）成以（yǐ）上（shàng）4中隔（gé）聲屏障的高度可以根據設計要求自由組合，亦可根據（jù）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.
