Decoration pollution in summer teaches you six way

With the continuous rise of temperature, the release of harmful gases mainly formaldehyde also jumped up. Experiments show that the formaldehyde volatilized from wooden furniture and floors will increase the concentration of formaldehyde in the air by 0.15 to 0.37 times every one degree Celsius rise in room temperature. Many owners who decorate after the Spring Festival are about to move into their new houses. How can we control the air before moving in? At present, the formaldehyde treatment technology on the market is still relatively chaotic. Which method is really scientific and effective? We visited a number of experts from the interior decoration association and commented on several popular methods in the market

plant absorption method

plants have a strong ability to absorb formaldehyde, such as cactus, Chlorophytum comosum, aloe, Clivia, iron tree, chrysanthemum, etc

expert comments: many plants do have a certain air purification effect. However, this does not mean that plants can completely remove formaldehyde from the air. The absorption of formaldehyde by plants can only play an auxiliary role in the whole process of purifying the air. If the formaldehyde content in the air is too high, it may even cause the death of plants themselves. In addition, because they consume the surrounding formaldehyde through photosynthesis, the absorption efficiency will be very low in the evening and rainy weather

folk method

put tea dregs, grapefruit peel, onion slices, pineapple pieces, etc. in the newly decorated room or fumigate the whole room with white vinegar

expert comments: the use of tea residue, grapefruit peel, onion slices, pineapple blocks and other soil methods can only play a role in covering, such as covering the odor of the toilet. These things will not absorb formaldehyde in the air. In addition to these things, some people also like to use perfume and air fresheners, which is not advisable, because the chemical raw materials in perfume and air fresheners may react with substances in the air, causing secondary pollution

activated carbon adsorption method

solid activated carbon has the characteristics of many pores, and has a strong adsorption and decomposition effect on harmful substances such as formaldehyde. The smaller the particle of activated carbon, the better the adsorption effect

expert comments: the adsorption effect of activated carbon on formaldehyde is obvious. It should be noted that the amount of activated carbon should be different according to the size of the space. In addition, the activated carbon needs to be replaced after it is adsorbed to a certain extent. Although the effect of activated carbon is good, like other methods, it can not completely remove formaldehyde from the air

purifier treatment method

at present, the air purifiers on the market are divided into anion type, ozone type, filtration and adsorption type, electrostatic integration type and photocatalyst type. Different air purifiers have different working principles. For example, the negative ion type produces negative ions to decompose the odor and attached smoke in the air, so as to achieve the purpose of purifying indoor air

expert comments: air purifiers have certain effects in absorbing formaldehyde, but air purifiers are generally only effective when used in closed spaces. If the air purifier is used with the window open, it will not only have little effect, but also waste electricity

chemical purification method

it mainly consumes formaldehyde in the air through physical adsorption or chemical reaction; At present, there are two kinds of formaldehyde capture agents on the market. One is to purify the air by neutralizing formaldehyde and generating harmless substances; The other is to purify the air by blocking formaldehyde and preventing its volatilization

expert comments: advantages: high efficiency, immediate effect after use; Disadvantages: treat symptoms but not root causes; The release of formaldehyde is a long process, which lasts for several years or even decades. Only a small part of formaldehyde released is absorbed or reacted

latex paint absorption method

using latex paint to absorb and decompose formaldehyde is a new concept; Through a unique formula, lotion with special molecular groups that can adsorb and decompose formaldehyde is selected to purify the air at home

expert comments: use chemical reactions to consume free formaldehyde in the air and generate water molecules that are harmless to human body and the environment. This is a safe and environmentally friendly method without any risk of release. Relatively speaking, latex paint adsorbing formaldehyde will have some shortcomings in convenience and safety, while Nippon formaldehyde net will be safer with its active and continuous absorption. Formaldehyde net fully eliminates formaldehyde molecules in the air through chemical reaction, decomposes into harmless water molecules, and has a long-lasting effect - from the completion of painting, it absorbs and decomposes formaldehyde 24 hours a day. In addition, its effective coefficient in decomposing formaldehyde is also very reassuring: the national standard requires the concentration of indoor formaldehyde to be less than 0.10 mg/m3, while the net total effect of Nippon aldehyde has been tested by the national building materials testing center. When the concentration of indoor formaldehyde is 5 to 10 times higher than the national standard, the effective decomposition rate of indoor formaldehyde is as high as 86%
