Unfired boric sludge foaming acoustical board

Abstract

The invention discloses an unfired boric sludge foaming acoustical board. According to the technical scheme, the unfired boric sludge foaming acoustical board is characterized in that a built-in frame is horizontally placed on a mold, after short steel pipes in the built-in frame are inserted into stand columns, boric sludge cement foaming agent is poured on the periphery of the built-in frame, the built-in frame is totally inlaid in the boric sludge cement foaming agent, maintenance is performed according to a conventional cement product maintenance method, and packaging is performed to form an unfired boric sludge foaming acoustical board finished product; the boric sludge cement foaming agent is prepared from acidized boric sludge, high-viscosity attapulgite clay powder, cement and other raw materials; the boric sludge cement foaming agent and the built-in frame form an integrated whole after the boric sludge cement foaming agent is cured, and thus the overall strength, the bending resistance and the actual using effect of the unfired boric sludge foaming acoustical board are improved. The unfired boric sludge foaming acoustical board not only can be used for effectively controlling noise pollution but also has the functions of heat preservation and air purification and is suitable for being mounted in facilities such as expressways, 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-burning boron mud 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 t...

Problems solved by technology

[0006] The stockpiling and disposal of boron mud not only occupies a large amount of land, but also alkalizes the soil near the stockyard and causes the migration and transformation of boron. Where the boron mud is discharged, no grass can grow, and its lye can dissolve into the groundwater, making the surrounding The production of farmland is reduced, and in severe cases, the crops may fail to produce, and the surrounding drinking water will be polluted

Due to the fine particles of boron mud, after losing moisture, it will often scatter with the wind, causing pollution to the atmospheric environment
