Problems solved by technology

[0004] At present, the texture of the foamed sound-absorbing panels sold on the market is relatively brittle, and the overall strength, bending resistance and use effect of the sound-absorbing panels are not ideal; in the process of installing the sound-absorbing panels on the wall of the building, the sound-absorbing panels need to drill 4 on-site The above bolt holes are not only labor-intensive and time-consuming, but also increase the difficulty of construction, and it is easy to damage or shatter the sound-absorbing panel when drilling. When the sound-absorbing panel is installed on the wall of the building, due to the effect of gravity, drilling The sound-absorbing panels behind the holes are broken and peeled off from the building wall

Embodiment Construction

[0043] Below in conjunction with embodiment the present invention will be further described:

[0044] The non-fired phosphogypsum foam sound-absorbing board is a rectangular plate-like object 1, which is composed of a built-in frame 2 and a phosphogypsum cement foaming agent 3. The built-in frame 2 is designed with 6 short steel pipes 5; the built-in frame 2 is laid flat On the mold 4, after the short steel pipe 5 in the built-in frame 2 is inserted into the column 6, the phosphogypsum cement foaming agent 3 is used to cast it on the periphery of the built-in frame 2, and after the built-in frame 2 is completely embedded in the inside of the phosphogypsum cement foaming agent 3, It is a semi-finished product of non-fired phosphogypsum foamed sound-absorbing board; after 5 days of static curing treatment, the semi-finished product of non-fired phosphogypsum foamed sound-absorbing board is taken out of the mold, and it is maintained according to the conventional maintenance metho...

Abstract

The invention discloses an unfired ardealite foamed acoustic board. The technical scheme is characterized in that an internal frame is horizontally placed on a mould, after short steel pipes in the internal frame are inserted into vertical columns, ardealite cement foaming agent is poured on the periphery of the internal frame, the internal frame is completely embedded inside the ardealite cement foaming agent, and the board is maintained according conventional cement product maintenance methods and packaged to form a finished product of the unfired ardealite foamed acoustic board. The ardealite cement foaming agent is composed of dewater ardealite, high-viscosity altapulgite clay powder, cement and the like. The ardealite cement foaming agent is cured and integrated with the internal frame, and integral intensity, deflection resistance and actual using effects of the unfired ardealite foamed acoustic board are improved. The unfired ardealite foamed acoustic board not only can effectively control noise pollution but also has functions of thermal insulation and air purification and is suitable for being mounted in facilities such as highways, viaducts, urban light rails, subways, public places and the like.

Description

technical field [0001] The invention relates to a sound-absorbing board, in particular to a non-fired phosphogypsum foamed sound-absorbing board. Background technique [0002] Urban noise seriously affects the normal life and personal health of urban residents. Urban noise mainly refers to traffic noise, factory noise, construction noise and social life noise. It has become one of the conspicuous urban environmental pollution problems. [0003] Usually, sound-absorbing materials are used to produce some sound-absorbing panels, sound-insulating walls, sound-absorbing nets and mufflers to control noise pollution, and some sound-absorbing materials are produced after foaming to improve product performance. [0004] At present, the texture of the foamed sound-absorbing panels sold on the market is relatively brittle, and the overall strength, bending resistance and use effect of the sound-absorbing panels are not ideal; in the process of installing the sound-absorbing panels on...
