Calcium Carbide environmental sound-absorbing panels

The present invention discloses an environmentally sound-absorbing panels carbide slag, the gist of the technical solution is that the built-in frame on the flat die, a short steel tube after the frame built into the upright, using composite carbide slag foaming cast inline frame a peripheral, built-in frame is completely embedded within the composite foaming agent, which solidified on standing after treatment, after baking and cooling, packaging for the environmental sound-absorbing panels carbide slag products. Compound carbide slag foaming agent after acidification carbide slag powder, attapulgite clay powder and hydrogen peroxide raw material composition; composite carbide slag after the blowing agent is cured to form an integrated whole with the built-in frame, increasing the carbide slag the overall strength of the environmental sound-absorbing panels, bending resistance and the practical effects, not only to enhance the sound absorbing effect and noise pollution control, but also has thermal insulation, adsorption and air purification functions. Calcium Carbide environmental sound-absorbing panels suitable for installation in highways, viaducts, urban light rail, metro, public places and other facilities.
