The installation of sound-absorbing foam glass is simple and the decorative effect is beautiful.
the installation method of foam glass is relatively simple. Generally, cement adhesives are used to stick to the wall, and metal keel can also be used for installation. As the maximum plate width is 400mmx400mm, it is smaller than other sound-absorbing materials such as mineral wool board. The visual effect of keel installation is poor
there are three forms of solid wall pasting, namely, close laying, double side seam and four side seam. The seam width is about 10~30mm. When the plate thickness is large, the seam width should be capitalized. On the contrary, when the plate thickness is small, the seam width should be smaller, and the solid board seam type. On the one hand, the function of leaving seams can eliminate the parallax of the thickness change of the plate, that is, the thickness of the plate is a little different, which fundamentally solves the difficulty of insufficient capital investment. On the other hand, it can enhance the three-dimensional feeling of the surface of the sound-absorbing material and improve the decorative effect. At the same time, after leaving the seam, it can also increase the sound-absorbing effect of the edge of the material and improve the sound-absorbing effect of the material
the width of the board is 400mmx400mm, the thickness of the board is 50mm, and the width of the seam is 15m. The three major key projects of its 300000 ton biological composite material project, 100000 ton engineering plastic upgrading and reconstruction project, 3D printing consumables intelligent manufacturing demonstration factory and 3D printing display experience cloud factory are officially launched. The sound absorption coefficient measured by its close laying, two side and four side seams, and three forms of board seams, namely close laying There is no significant change in the low-frequency sound absorption coefficient below 500Hz and the high-frequency sound absorption coefficient above 3150hz, but the edge of the frequency range of 630~2500hz has a significant impact on the sound absorption coefficient, and the average sound absorption coefficient is 0.43, 0.47 and 0.52 respectively, with each additional bilateral seam, the average sound absorption coefficient increases by about 10%
