Paint knowledge six ways to deal with formaldehyde to solve the problem of decoration air pollution

Core tip: with the rising temperature in Beijing, the emission of formaldehyde based harmful gases is also rising Experiments show that the formaldehyde emitted by wood furniture and floor will increase the formaldehyde concentration in the air by 0.15 to 0.37 times every one degree Celsius rise of room temperature Many owners who decorate after the Spring Festival are about to move into their new houses How can they control the air before they move in? At present, the formaldehyde treatment technology in the market is still confused Which method is really scientific and effective? We visited many experts of Interior Decoration Association and commented on several popular methods in the market Plant Paint knowledge how about Akzo Nobel Powder Coating Recommended introduction: powder coating is a kind of coating with different form from general coating, which is in powder form It is a new type of coating, because of its own advantages and more and more known by people Let's introduce Akzo Nobel Powder coating Akzo Nobel Powder coating is a cost-effective coating solution, which can be applied to different kinds of products After the treatment of static electricity and fire baking, a tough and durable coating surface will be formed, with the least impact on the environment Since the introduction of this technology, powder coating has been able to continue to maintain the Paint Home News: with the rising temperature in the capital, the emission of formaldehyde based harmful gases is also rising Experiments show that the formaldehyde emitted by wood furniture and floor will increase the formaldehyde concentration in the air by 0.15 to 0.37 times every one degree Celsius rise of room temperature Many owners who decorate after the Spring Festival are about to move into their new houses How can they control the air before they move in? At present, the formaldehyde treatment technology in the market is still confused Which method is really scientific and effective? We visited many experts of Interior Decoration Association and commented on several popular methods in the market Plant absorption method plants have strong ability to absorb formaldehyde, such as cactus, Chlorophytum, aloe, Clivia, iron tree, chrysanthemum, etc Experts comment: many plants do have certain air purification effect However, this does not mean that plants can completely remove formaldehyde in the air The absorption of formaldehyde by plants can only play an auxiliary role in the whole process of air purification If the formaldehyde content in the air is too high, it may even cause the death of the plant itself In addition, because they consume the surrounding formaldehyde through photosynthesis, the absorption efficiency will be very low at night and rainy days In the folk way, tea dregs, grapefruit peel, onion slices and pineapple pieces are placed in the newly decorated room or the whole room is fumigated with white vinegar Experts comment: the use of tea residue, grapefruit peel, onion slices, pineapple pieces and other soil methods can only play a role in covering, such as covering the peculiar smell of toilets These things don't absorb formaldehyde in the air In addition to these things, some people also love to use perfume and air fresheners This is not advisable, because the chemical materials in perfume and air fresheners may react with the substances in the air, resulting in two pollution The solid activated carbon with activated carbon adsorption method has many pores, and has strong adsorption and decomposition effect on formaldehyde and other harmful substances The smaller the particles of activated carbon, the better the adsorption effect Experts comment: the adsorption effect of activated carbon on formaldehyde is very obvious It should be noted that the amount of activated carbon placed should be different according to the size of the space In addition, the activated carbon needs to be replaced after adsorption to a certain extent Although the effect of activated carbon is good, but like other methods, it can not completely remove formaldehyde in the air At present, the air purifiers in the market are divided into anion type, ozone type, filtration adsorption type, electrostatic integrated type and photocatalyst type Different air purifiers have different working principles For example, the anion type is to produce anion, decompose the peculiar smell and attached smoke in the air, so as to achieve the purpose of purifying indoor air Expert comment: air purifier has certain effect in absorbing formaldehyde, but it is only effective in closed space If the air purifier is used with the windows open, it will not only have little effect but also waste electricity Chemical purification method 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 sealing formaldehyde and preventing the volatilization of formaldehyde Experts comment: advantages: high efficiency, immediate effect after use; disadvantages: no cure for symptoms; formaldehyde release is a very long process, lasting for several years or even decades, only a small part of formaldehyde is absorbed or reacted It is a completely new idea to use latex paint to absorb and decompose formaldehyde The unique formula is used to select the special molecular groups of formaldehyde which can adsorb and decompose Expert comment: use chemical reaction to consume free formaldehyde in the air, produce water molecules harmless to human body and environment This is a safe and environmentally friendly way without any risk of re release In contrast, the emulsion paint adsorbing formaldehyde will have some disadvantages in convenience and safety, and libonaldehyde will be safer in its active and continuous absorption mode Aldehydes completely eliminate formaldehyde molecules in the air through chemical reaction, decompose into harmless water molecules, and last for a long time - from the completion of painting, absorb and decompose formaldehyde 24 hours a day In addition, its effective coefficient in the decomposition of formaldehyde is also very reassuring: the national standard for indoor formaldehyde concentration is less than 0.10 mg / m3, while the libonaldehyde net total effect is tested by the national building materials testing center, under the condition of 5-10 times higher than the national standard for indoor formaldehyde concentration, the effective decomposition rate for indoor formaldehyde is as high as 86% Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
