The product description
Perforated board, also known as SAN Franciscan ya static sound absorption board, is the use of SAN Franciscan high-strength paper surface gypsum board according to different design patterns, through high precision perforation and the formation of a high-grade gypsum based paper surface sound absorption board. These different types of holes on the surface of the SAN Franciscan ya jing board not only add an aesthetic effect to the traditional gypsum board, but also produce the effect of noise reduction and sound absorption through these holes. The hole that layout is densely densely also strengthened the breath function of plasterboard, also have good effect and energy-saving effect to the respect with adjusting indoor temperature and humidity.
Sound absorption principle
Sound absorption material inside is the principle of a large number of tiny pore connectivity, when voice incoming material surface components, part of sound energy is reflected, part through material, and a due to the vibration of the component materials or voice in which friction transmission with the surrounding medium, the sound energy into heat energy, sound energy loss, known as the sound is absorbed by the material.
The necessary conditions for porous materials to absorb sound are:
There are a lot of voids in the material, which are connected with each other, and the voids go deep into the material. With metope or smallpox existence the perforated board of air layer, although material itself is sound-absorbing performance is very poor, this kind of structure also has sound-absorbing performance, be like perforated plasterboard. This type of absorption is called helmholtz resonance absorption.
The installation specification
1. SAN francisco-based yajing sound-absorbing board is installed on the face keel like the ordinary paper gypsum board.
2. In order to maintain the integrity of the figure, the overall layout should be done before installation, and the positions of lights, access port and air conditioning port should be taken into consideration.
3. It is recommended that the spacing of the surface keel should be 400mm and 600mm to maintain the flatness.
4. The installation of SAN ferronji ya static sound absorption board should be from the middle to the four directions, in order to make the figure symmetrical, complete and beautiful.
5. In order to facilitate the painting, it is recommended to use 25mm self-tapping screw of saint frankie, and ensure that the plate surface is not protruded.
6. Roll coating on the surface of the sound absorption board of Santa fe longji ya static sound absorption board, so as to avoid the paint infiltration into the hole on the non-woven cloth on the back of the perforated board, affecting the sound absorption effect.
