Sell Plant Acoustic Cellulose

Description

Plant Acoustic Cellulose is made from natural plant fiber like used wood, bark, waste paper ***** chemical processing of fire retardance and moth proofing etc. It is a new green product that is not including asbestos, glass fiber and other artificial mineral fibers. The acoustic theories of plant cellulose is to achieve properties of heat preservation , heat insulation and sound insulation through the closed air between the ***** is widely used in construction. eg. National Grand Theatre has a large roof of ****0m2 . In order to reduce the loading of structure, the facing adopts the titanium as light roof.But there is a problem that indoor will be disturbed by the rain noise caused by dropping on mental surface when it rains.A lot of experiments on the air sound insulation and raining noise insulation about this roof struction have been done at the Architecural Physics Lab of Tsinghua University .Based on plenty of experiment data, they put forword a creative plan that spraying cellulose of *5mm thickness at the bottom of roof is to prevent the rain noise, and this plan has been ***** main reasons that cellulose spray can greatly improve the soundproof properties are as follows: First, cellulose average spray attached on steel plate of 2mm thickness under the roof has acoustic damping effects and improves the vibration mode of steel plate and highly improves the soundproof properties of the middle and low frequency. Second, cellulose is a kind of sticky graininess materials which have a good sealed effect.
