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

[0039] Below in conjunction with embodiment the present invention will be further described:

[0040] The non-fired carbide slag foam sound-absorbing panel is a rectangular plate-shaped object 1, which is composed of a built-in frame 2 and a carbide 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, it is poured on the periphery of the built-in frame 2 with a calcium carbide cement foaming agent 3, and after the built-in frame 2 is completely embedded in the interior of the carbide cement foaming agent 3, It is a semi-finished product of non-burning calcium carbide slag foamed sound-absorbing panel; after standing and curing, the semi-finished product of non-burning carbide slag foamed sound-absorbing panel is taken out of the mold, maintained according to the conventional maintenance method of cement products, an...

Abstract

The invention discloses a non-fired calcium carbide slag foamed sound-absorbing board. The main point of the technical proposal is that the built-in frame is placed flat on the mould, and after the short steel pipes in the built-in frame are inserted into the columns, the calcium carbide slag cement foaming agent is used to pour the Around the built-in frame, the built-in frame is completely embedded in the interior of the calcium carbide cement foaming agent. It is cured according to the conventional maintenance method of cement products, and it is packaged as a finished product of non-burning carbide slag foamed sound-absorbing board; the calcium carbide slag cement foaming agent is made of acidified Composed of calcium carbide slag, high-viscosity attapulgite clay powder and cement and other raw materials; carbide slag cement foaming agent is cured to form an integrated whole with the built-in frame, which increases the overall strength and bending resistance of the unburned carbide slag foamed sound-absorbing panel Ability and actual use effect; non-burning carbide slag foam sound-absorbing panels can not only effectively control noise pollution, but also have the function of heat preservation and air purification, suitable for installation in highways, viaducts, urban light rail, subways, public places and other facilities .

Description

technical field [0001] The invention relates to a sound-absorbing board, in particular to a foamed sound-absorbing board with unfired carbide slag. 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 ...
