Title:
FORMALDEHYDE-PURIFYING AND SOUND-INSULATING ECOLOGICAL BOARD
Document Type and Number:
WIPO Patent Application WO/2022/126500
Kind Code:
A1
Abstract:
A formaldehyde-purifying and sound-insulating ecological board, comprising a base plate (1), wherein a splice plate (2) is fixedly mounted at an end of the base plate (1); a splice groove (5) is cut at the end of the base plate (1) that is away from the splice plate (2); three expansion grooves (4) are cut on the base plate (1); the three expansion grooves (4) are arranged at equal distances; a plurality of sound absorbing holes (6) are cut on the base plate (1); four first sealing plates (3) are buckled on the base plate (1); and four second sealing plates (7) are buckled on the base plate (1). Activated carbon particles (13) in the base plate (1) can absorb formaldehyde indoors. When sound waves are in contact with the activated carbon particles (13), some of the sound wave energy can be consumed by means of the activated carbon particles (13). A V-shaped channel (171) is cut in a built-in partition plate (17), and when sound waves pass through the V-shaped channel (171), the lengths of propagation paths of the sound waves are prolonged, and more sound wave energy is consumed. The ecological board not only absorbs sounds but also formaldehyde indoors, thereby effectively purifying indoor air and greatly increasing the diversity of functions of the ecological board.
