Soundproof rock wool board
The high-density rock wool board for the partition wall is simply referred to as "sound-proof rock wool".
It is because it is usually used for sound insulation of light walls. The typical structure of this lightweight wall is:
Gypsum board (1 or more layers ) + keel + rock wool board + gypsum board (1 layer or multi-layer ) rock wool board plays a sound-absorbing role here, absorbing sound waves passing through the gypsum board, reducing sound waves in the plaster The back and forth reflection in the cavity formed between the plate, the keel and the gypsum board, thereby achieving the effect of increasing the sound insulation of the wall. It has been proved that the light-weight wall after the rock wool board with a packing density of 80-150 kg/m3 is improved by 8 to 15 decibels than the sound-insulating effect of the rock wool without gypsum board alone .
This rock wool board is not a rock wool board
Different from the inferior rock wool sold in the building materials market, the special rock wool board for the silent wall is a new product specially developed for light wall sound insulation, and has been fully acoustically optimized:
Density - The density of rock wool board for mute treasure partition is set to 100-200kg/m3 , which is the best density for wall sound insulation, which not only guarantees the best sound insulation, but also guarantees the wall and the material itself. Strength of. The density of rock wool sold in the building materials market generally does not exceed 60kg / m3 , the sound insulation effect is not good and the hand feel is very soft, and it is easy to completely lose its sound insulation function due to sagging;

Slag ball - Silent treasure partition wall special rock wool board is not one-sided pursuit of the content of the slag ball, but strictly control the particle size of the slag ball and ensure the even distribution of the slag ball in the rock wool board. When the sound wave encounters the slag ball, the energy is reduced by reflection and scattering, so that the sound insulation effect of the rock wool board is improved. The rock wool sold in the building materials market is easy to form soundproofing holes due to uneven density;
The amount of glue - the special rock wool board of the mute treasure partition wall is hand-continued to ensure the uniformity and strength of the cotton layer. It is pressed by high temperature without adding too much adhesive, thus maintaining the fireproof of rock wool well. performance. The rock wool sold in the building materials market maintains the strength at low density and adds a large amount of glue, which not only reduces the fireproof performance, but also causes the rock wool board to sag and sag;
Dimensions - special rock wool board for silent wall is convenient for construction. According to the standard spacing of the keel, the width is determined to be 800mm , 600mm , 400mm, etc., so that it is not necessary to cut the rock wool board during construction, thus reducing rock wool. The debris is irritating to the construction workers. The reason why the rock wool sold in the building materials market is limited to equipment and the like is generally required to be cut at the construction site.
After the optimized design, the special rock wool board for the mute treasure partition wall can improve the sound insulation effect of the light wall by more than 10 decibels.
