The more prominent advantage of the mineral wool sound-absorbing board is its outstanding fire resistance. The mineral wool board is made of mineral wool as the main raw material, with a melting point of up to 1300 ° C, no harmful gas is generated in the process, and it has high fire resistance. Therefore, in some buildings with prominent fire protection functions, some people choose to use mineral wool sound-absorbing panels to decorate the walls. There are two construction methods for installing the mineral wool sound-absorbing panel on the wall, one is to paste it directly on the wall, and the other is to install it together with the light steel keel. Before installation, both methods must measure the actual size of the wall, confirm the installation position, determine the horizontal and vertical lines, and determine the cut-out reserved size of wire sockets, pipes and other objects. Direct mounting method, pay attention to the base wall to be flat, clean and free of dust. Apply at least 5 dots of plaster plaster on the back of the mineral wool board and stick it to the wall; press the T-plastic or T-aluminum-alloy bead on the edge of the sound-absorbing board; the board corners can be punched with expansion screws to press the white pressure plate Fixed to the wall.
The wall installation of mineral wool sound-absorbing panels can also be made of light steel keels or wooden keels. For this installation, attention should be paid to the arrangement of the keels to fit the arrangement of the sound-absorbing panels. The distance between wooden keels should be less than 300mm, and the distance between light steel keels should not be more than 400mm. The installation of the keel should be handled in the length direction of the mineral wool sound-absorbing board, and the distance from the surface of the keel to the wall is generally 50mm. If fillers are required in the keel, they must be installed and processed according to the design requirements to ensure that the installation of the sound-absorbing panels will not be affected.
In addition, it should be noted that the impact resistance of the mineral wool sound-absorbing board is not enough, and it is not suitable for wall installation in some occasions. In addition, special attention should be paid to the selection of glue for the installation of mineral wool sound-absorbing panels, and the use of glue that meets the national environmental protection requirements should be considered. Therefore, in the process of wall sound-absorbing decoration, we should select suitable materials according to specific scenes and specific requirements, and maximize strengths and avoid weaknesses to achieve the expected design goals.
