Problems solved by technology

[0010] The formaldehyde emitted continuously in the board is emitted outward through the coating after the formaldehyde decomposing agent or formaldehyde scavenger is sprayed on the surface of the board and furniture. A relatively slow chemical reaction process, the technology lacks the means to allow the emitted harmful gas to stay in the coating, which directly causes the harmful gas to be emitted through the coating without being effectively decomposed and removed, making it difficult to receive satisfactory removal. aldehyde effect

specific Embodiment 1

[0045] Specific embodiment 1, such as figure 1As shown, a method for eliminating indoor chemical pollution in situ, the removal device is arranged on the surface of the pollution source carrier, and the removal device includes one or more than two composite layers of the stagnant layer, particle layer or decorative layer, and the removal device The interior forms a wave-shaped airflow path for the emission of polluted gases. Among them, the pollution source carrier is a carrier that emits chemical pollution gas such as boards, furniture or home decoration.

[0046] A method for in-situ elimination of indoor chemical pollution includes the following steps:

[0047] a. Prepare a pollution source removal device, that is, the attachment on the surface of the pollution source carrier, which is divided into a retention layer 1, a particle layer 2 and a decoration layer 3, and the three layers are bonded and compounded;

[0048] b. Cover the cleaning device prepared in step a on th...

specific Embodiment 2

[0085] Specific embodiment 2, a kind of method for eliminating indoor chemical pollution in situ comprises the following steps:

[0086] a. Prepare a pollution source removal device, select any two of the stagnation layer 1, the particle layer 2 and the decoration layer 3, and connect them by grid stitching at a certain distance;

[0087] b. Suspend the double-layer cleaning device on the surface of the pollution source.

specific Embodiment 3

[0088] Specific embodiment 3, a kind of method for eliminating indoor chemical pollution in situ comprises the following steps:

[0089] a. Prepare a pollution source removal device, the removal device includes a retention layer 1, a particle layer 2 and a decoration layer 3, and is riveted by connecting nails to form a three-layer structure;

[0090] b. Bond the cleaning device with three-layer structure to the surface layer of the pollution source.

Abstract

The invention relates to the technical field of pollution sources and indoor pollution control, and in particular to a method for eliminating indoor chemical pollution in situ. In the method, a cleaning device is arranged on the surface of a pollution source carrier, and the cleaning device includes one of a stagnant layer, a particle layer or a decorative layer. One layer or more than two layers of composite layer, the thickness of the cleaning device is 1mm-60mm, the specific surface area is 50-400m2 / g, and the aperture is 0.1mm-0.5mm. Distributed airflow path. Combining functional materials that remove formaldehyde and other pollutants with fibers, etc., reduces the speed at which pollutants are emitted, and forms a layer of pollutant retention on the surface of the pollution source. The pollutants are on the interface with a large specific surface area and functional materials. function to achieve efficient removal of pollutants.

Description

technical field [0001] The invention relates to the technical field of furniture and indoor pollution control, in particular to a method for eliminating indoor chemical pollution in situ. Background technique [0002] In view of the high reactivity and low cost of organic solvents such as aldehydes, ketones, and lipids, they have been used as important components of adhesives and coatings in the production and bonding of panels in the furniture and interior decoration industries. As a result, the chemical pollution of formaldehyde, acetaldehyde, acetone, ethyl ester and other organic solvents brought by indoor furniture and decoration materials in homes, offices, and public places has become a public enemy of people's health, the most common of which is formaldehyde. At present, the formaldehyde emission of the highest level E1 wood-based panel in China is 1.5 mg / L, while that of E0 in Europe and America is 0.5 mg / L, and the Japanese requirement is 0.3 mg / L, but the actual s...
