產(chǎn)品簡(jiǎn)介

SOUNDON 的質(zhì)量加載乙烯基屏障 (Tuff Mass®) 是一種專門開(kāi)發(fā)的質(zhì)量層產(chǎn)品，具有良好的阻尼性能,，具有卓越的聲學(xué)傳輸損耗,。

SUNDONDUS 乙烯基質(zhì)量/阻尼板提供高達(dá) 32 的 STC 額定值。 它是一種低成本材料,，用于各種海洋和陸地應(yīng)用,。 下面的圖示顯示了作為懸浮屏障安裝的 Tuff-Mass。 這種典型的 Appli 陽(yáng)離子可以改善相鄰空間之間的傳輸損失,。

Soundown 的質(zhì)量加載乙烯基的阻尼性能和剛度特性相結(jié)合,，在將質(zhì)量層和阻尼器應(yīng)用于隔板和輕質(zhì)結(jié)構(gòu)艙壁時(shí)，它具有優(yōu)異的性能,，從而降低了機(jī)艙和結(jié)構(gòu)噪音的跨式任務(wù),。

英文介紹

SOUNDOWN’S Mass Loaded Vinyl Barrier (Tuff­ Mass®) is a specially developed mass layer product offering superior acoustic transmission loss com­bined with good damping properties.

SOUNDOWN'S Vinyl mass/damper sheet offers STC Ratings up to 32. It is a low cost material used for a variety of marine and land based applications. The drawing below shows Tuff-Mass installed as a suspended barrier. This typical appli­cation would improve transmission loss between adjoining spaces.

The combination of the damping and stiffness properties of Soundown’s Mass Loaded Vinyl gives it excellent performance as a combined mass layer and damper when applied to partition panels and lightweight structural bulkheads, reducing trans­ mission of both airborneand structurebourne noise.
