Embodiment Construction
[0038] Below in conjunction with embodiment the present invention will be further described:
[0039] The cement foam sound-absorbing board is a rectangular plate-shaped object 1, which is composed of a built-in frame 2 and a cement foaming agent 3, and 6 short steel pipes 5 are designed in the built-in frame 2; the built-in frame 2 is placed 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 cement foaming agent 3, and after the built-in frame 2 is completely embedded in the interior of the cement foaming agent 3, it is a semi-finished cement foam sound-absorbing board; After standing and solidifying, the semi-finished cement foam sound-absorbing board is taken out of the mold, cured according to the conventional maintenance method of cement products, and packaged as a finished cement foam sound-absorbing board.
[0040] The cement foaming agent batching is made up of fo...
