A-class fireproof rock wool board is one of the oldest and most widely used sound-absorbing materials. It is widely used in sound insulation, heat preservation, and fire prevention of light walls. Silent Po has a wholly-owned Grade A fire-resistant rock wool board factory with an annual production capacity of more than 10,000 tons. The products are of high quality and exported to Russia, Romania, Kazakhstan, India, Sri Lanka and other countries. Grade A fire-resistant rock wool board high-density A-class fire-resistant rock wool board is called "soundproof A-class fire-resistant rock wool board". Because it is usually used for soundproofing of light walls. The typical structure of this lightweight wall is: gypsum board (1 or more layers) + keel + A fireproof rock wool board + gypsum board (1 or more layers) A fireproof rock wool board is played here It absorbs sound and absorbs sound waves passing through the gypsum board, reducing the back and forth reflection of sound waves in the cavity formed between the gypsum board, keel, and gypsum board, thereby achieving the effect of increasing the amount of sound insulation of the wall.
Facts have proved that the light wall of Class A fireproof rock wool board with a density of 80-150kg/m3 is 8-15dB higher than that of a Class A fireproof rockwool board without gypsum boards. This Grade A fireproof rock wool board is not the same as the water rock wool board quoted grade fireproof rock wool board and the poor grade A fireproof rock wool board sold on the market is very different, Silent Po partition dedicated A grade fire rock wool board The panel is a new type of product specifically developed for light wall sound insulation and has been fully acoustically optimized:
Density - The density of the special Class A fireproof rock wool board for the Silencer partition wall is set to 100-200kg/m3. This is the best density for the wall sound insulation, which not only guarantees the best soundproof effect, but also guarantees the wall The strength of the body and the material itself. The density of Class A fireproof rock wool board sold by the building materials market is generally not more than 60kg/m3, the sound insulation effect is not good and the hand feel is very soft, and it is easy to completely lose its soundproof function due to sagging;
Slag Ball - Special Class A fireproof rock wool board is not a one-sided pursuit of the content of the slag ball, but strictly control the size of the slag ball and ensure the even distribution of the ball in the Class A fire rock wool board. When the sound wave encounters the slag ball, it will reduce the energy due to reflection and scattering, so that the soundproof effect of the Class A fire-proof rock wool board can be improved. The Grade A fireproof rock wool board sold by the building materials market is prone to sound insulation due to uneven density;
Glue Amount - The special A-class fire-resistant rock wool board is hand-supplied with cotton, which ensures the uniformity and strength of the cotton layer. It is formed by pressing at a high temperature without adding too much adhesive, so that the A-class fire-resistant rock is well maintained. Cotton wool felt for glass wool price fire performance. A grade fireproof rock wool board sold by the building materials market to maintain the strength at low density, adding a lot of glue, which will not only reduce the fire performance, and the aging of the glue will lead to A grade fire rock wool board scattered sagging;
Dimensions - Special Grade A fireproof rock wool board For the convenience of construction, the width is determined to be 800mm, 600mm, 400mm according to the standard spacing of the keel, so that it is not necessary to cut the Class A fireproof rock wool board during construction. Reduces the stimulation of A-level fireproof rock wool board scrap to construction workers. The reason why the A-grade fire-resistant rock wool board sold in the building materials market is limited to equipment and other reasons is generally required to cut at the construction site. After optimization and design, the special-grade fire-proof rock wool board for Silencer partition wall can improve the sound insulation effect of the light wall by more than 10 decibels.
