Abstract
The present invention relates to pollution sources, indoor pollution Treatment process field, more particularly, to the method in situ for eliminating ski dome, remove device is arranged at pollution sources carrier surface by this method, the remove device includes the composite bed of one layer or more than two layers in retention layer, stratum granulosum or decorative layer, the thickness of the remove device is 1mm 60mm, and specific surface area is 50 400m2/ g, aperture are 0.1mm 0.5mm, the current path that remove device is internally formed wave mode or broken line type, distributed for dusty gas.The functional material for removing the pollutant such as formaldehyde and fiber etc. are combined together, reduce the speed that pollutant outwards distributes, the retention layer of one layer of pollutant is formed on pollution sources surface, pollutant is had an effect on the big interface of specific surface area with functional material, and pollutant is efficiently removed so as to realize.
Description
Technical Field
The invention relates to the technical field of furniture and indoor pollution treatment, in particular to a method for eliminating indoor chemical pollution in situ.

In view of the characteristics of high reactivity and low cost of organic solvents such as aldehydes, ketones, lipids and the like, the organic solvents have been used as important components of adhesives and coatings to be applied to the processes of manufacturing and bonding plates in furniture and interior decoration industries, so that chemical pollution of organic solvents such as formaldehyde, acetaldehyde, acetone, ethyl ester and the like brought by interior furniture and decoration materials in families, offices and public places becomes a public enemy of human health, wherein formaldehyde is the most common. At present, the formaldehyde release amount of the highest-grade E1-grade artificial board in China is 1.5 mg/L, the formaldehyde release amount in Europe and America is E0 grade, the formaldehyde release amount is 0.5 mg/L, and the Japanese requirement is 0.3 mg/L, but in the practical situation, pollution emission exists only in application, and in any situation, many boards are used in an overproof way, so the national standard of indoor chemical pollutants is set by the nation.
At present, the methods for removing chemical pollution in furniture and rooms generally comprise:
the indoor arrangement of specific green plants has a certain effect of eliminating chemical pollutants such as formaldehyde and the like which are emitted to the space.
The fresh air unit or the air purifier is used for replacing or reducing chemical pollutants such as formaldehyde and the like which are emitted to the space.
Indoor spraying with chemical or catalytic agent with removing effect is also effective on formaldehyde and other chemical pollutants diffused to space, and has the risk of secondary pollution.
The sealing agent is used for sealing the board, so that the emission of chemical pollutants such as formaldehyde and the like in the furniture such as the board and the like can be slowed down, the symptoms are treated, the root causes are not treated, and the hidden danger of chemical pollution in a pollution source exists forever.
The surface of the furniture and the decorative material is sprayed or coated with the coating with the function of removing, and the treatment is carried out in the first step of pollutant emission, which is a more efficient method.
From the release mechanism of the pollutants, no matter organic pollutants such as formaldehyde existing in the board in a free state or a combined state, the release process is a continuous dynamic process influenced by factors such as environmental temperature, humidity, concentration gradient and the like, and the continuous emission of chemical pollutants such as formaldehyde is inevitably accompanied as long as furniture and decorative materials exist. Based on this, the most effective solution to the problem is to solve the problem from the source principle, in addition to using the raw materials containing chemical pollutants in the least amount, in the above method for removing chemical pollutants in furniture and indoor, most directly and efficiently, the method for removing the chemical pollutants in furniture and decoration materials is to spray or coat the surface of the furniture and decoration materials with a coating with a removing function, which belongs to the methods for treating harmful gases in situ on the plate so as to reduce the source treatment of the emission to the environment, wherein the representative methods are ZL201210397449.7 formaldehyde decomposition method authorized in 5.20.2015, and ZL201210398138.2 formaldehyde removal method authorized in 2015 6.10.h, and the common characteristic is that the formaldehyde decomposer or the formaldehyde remover is sprayed on the surface of the plate, furniture or home decoration. The method related by the patent technology can convert and degrade formaldehyde emitted by the board or the decorative material into harmless substances, effectively reduces the pollution of free formaldehyde to indoor air, and does not cause secondary pollution. However, this technique also has the following drawbacks:
the formaldehyde that continuously gives off in the panel gives off through formaldehyde decomposer or formaldehyde scavenger spraying coating after panel, furniture surface outwards, and it is transient through the mode, and harmful gas gives off fast, and the decomposition of formaldehyde is clear away is a relatively slow chemical reaction process, lacks the means that lets the harmful gas who gives off detain in the coating in this technique, directly leads to the harmful gas effectively not to decompose and clear away and just give off through the coating outwards to hardly receive satisfied aldehyde effect. Therefore, a more efficient method for in-situ chemical decontamination of the interior of a room is needed.
