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 an unfired carbide slag foamed acoustic panel. According to the technical scheme, a built-in frame is flatly arranged on a mould, carbide slag cement foaming agents are poured on the periphery of the built-in frame after short steel tubes in the built-in frame are inserted into stand columns, the built-in frame is completely embedded inside the carbide slag cement foaming agents, maintenance is carried out according to a regular maintenance method of cement products, and an unfired carbide slag foamed acoustic panel finished product is packed; the carbide slag cement foaming agents are formed by acidized carbide slag, high-viscosity attapulgite clay powder, cement and other raw materials; the carbide slag cement foaming agents and the built-in frame form a whole after solidification, and thus the overall strength, the counter bending capability and the actual using effects of the unfired carbide slag foamed acoustic panel are improved. The unfired carbide slag foamed acoustic panel can effectively control noise pollution and further has the functions of heat preservation and air purification. The unfired carbide slag foamed acoustic panel is suitable for being mounted on facilities such as expressways, viaducts, urban light rails, metros and public places.

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 ...
