It crosses clamping piece to be clamped on the backing material plate, the adsorption plate includes being bonded to each other by a top plate and four side plates
Plate frame structure, the top plate and four side plates by being made of plastic plate, the adsorption plate it is opposite with the top plate
Side by one removably paper shell plate close, the paper shell plate offers multiple adsorption holes, in the plate frame structure
It is filled with methyl aldehyde adsorption material.
Preferably, in the Furniture panel of the adsorbable formaldehyde, the methyl aldehyde adsorption material is active carbon.
Preferably, in the Furniture panel of the adsorbable formaldehyde, four side plates of the adsorption plate are fitted in described
The outside of four sides of backing material plate.
Preferably, in the Furniture panel of the adsorbable formaldehyde, the medial surface of four side plates is provided with rubber
Item.
Preferably, in the Furniture panel of the adsorbable formaldehyde, the clamping piece is by the first side and along institute
It states the first side to constitute to the second side of a pair made of ipsilateral bending, and the clamping piece is plastic material.
Preferably, it in the Furniture panel of the adsorbable formaldehyde, is removed from the backing material plate in the adsorption plate
When, a protective film is attached on backing material plate.
The Furniture panel of adsorbable formaldehyde of the present invention is respectively set by the upper and lower surfaces in backing material plate
Adsorption plate, the adsorption plate is built-in to be filled with formaldehyde absorbing particle, can be with formaldehyde released in adsorption substrates plate, and then reduces base
Content of formaldehyde in material plate improves the safety in the Furniture panel use of adsorbable formaldehyde.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the Furniture panel of adsorbable formaldehyde of the present invention.
Specific embodiment
Present invention will be described in further detail below with reference to the accompanying drawings, to enable those skilled in the art referring to specification text
Word can be implemented accordingly.
As shown in Figure 1, the present invention provides a kind of Furniture panel of adsorbable formaldehyde, including：Backing material plate 7, is filled out by plate
It fills particle and the bound edge material being coated on around the plate filler particles is constituted, the backing material plate offers the release of perforation
Hole 8, the inside of the backing material plate are additionally provided with the duct 9 for several relief holes of connection being laterally extended, and the aperture in the duct is
0.2-0.4mm；Adsorption plate 1, a pair of of adsorption plate are overlapped in the upper and lower surfaces of the backing material plate, and the adsorption plate
1 is clamped on the backing material plate by clamping piece, and the adsorption plate includes being tied each other by a top plate 3 and four side plates 6
Plate frame structure made of conjunction, the top plate and four side plates by being made of plastic plate, the adsorption plate with the top
The opposite side of plate by one removably paper shell plate 5 close, the paper shell plate offers multiple adsorption holes 2, the plate frame
Methyl aldehyde adsorption material 4 is filled in frame structure.
The present invention overlaps adsorption plate in the two sides of backing material plate, and adsorption plate includes a plate frame structure and filling
Formaldehyde absorbing particle in the plate frame structure, backing material plate offer the relief hole of perforation, and the formaldehyde in adsorption plate is inhaled
Attached particle can be with the formaldehyde in adsorption substrates plate, and then reduces the content of formaldehyde in backing material plate.Five faces of adsorption plate are by moulding
Flitch is made, and makes it have good stability, and wherein one side is made using paper shell plate, when the formaldehyde absorbing in adsorption plate
When grain is needed replacing or regenerated, then paper shell plate is removed.Paper shell plate also has good adsorptivity simultaneously, facilitates backing material plate
In diffusion and release of the formaldehyde into adsorption plate.
Adsorption plate is clamped on backing material plate by clamping piece, can be disassembled from backing material plate.
The duct being laterally extended, several relief holes of hole link, to promote formaldehyde to adsorption plate are provided in backing material plate
Release, the content of formaldehyde in backing material plate is effectively reduced.The aperture in duct should not be too large, excessive, may will affect backing material plate
Intensity.
Preferably, in the Furniture panel of the adsorbable formaldehyde, the methyl aldehyde adsorption material is active carbon.
