Decoration formaldehyde is not clean, ventilation and odor can not be stayed for a year, common formaldehyde is basically IQ tax!
Some people say that they can move in in three months after renovation, which is not accurate. The degree of decoration of each home is different, minimalist decoration + solid wood furniture + big brand true. Solid wood composite flooring, ventilation can be moved in for a month. Large-area package wall panels + panel furniture + soft and hard wood for modeling + miscellaneous brand flooring, this "luxury" ventilation can not be occupied for a year, only the installation of wall panels and soft and hard bags will use a large number of foaming agents and structural glue, formaldehyde is hidden deep inside, the release cycle of up to 5-15 years.
In addition to the formaldehyde trick every year there are new tricks, money spent but can not achieve the effect, barely cleared the free formaldehyde in the air, more than ten hours after the source of pollution is re-released, not to mention the common means of removing formaldehyde on the market, the ability to remove aldehyde, the ability to remove water, most people use the means of removing aldehyde, formaldehyde is still "my own way".
First, the formaldehyde detection method is not formal, the formaldehyde detector bought for hundreds of dollars on the Internet can only be used as a reference, according to the latest national indoor air standard gbt 1883-2002 regulations, in the closed 12 hours environment formaldehyde content should not be greater than 0.1 mg / cubic meter, accurate data need to find an institution with cma testing qualifications.
Second, indoor formaldehyde is divided into three forms, free state. Adsorption state. Binding state, free formaldehyde is released into the air by the pollution source; Adsorbed formaldehyde is the free formaldehyde adsorbed by activated carbon packages, sofa curtains, etc., when adsorbed full, it will be re-released and become a new source of pollution; The binding state exists in the aldehyde-containing resin. Glue, as an indispensable raw material for the production of decoration materials, exists in decorative materials for a long time, and the slow release cycle is as long as ten years.
Third, the common aldehyde removal method is basically only effective for free formaldehyde, including green plant adsorption (green lotus, tiger tail orchid, hanging orchid, turtle back bamboo), activated carbon. Nano-mineral crystal adsorption, aldehyde-removing paste adsorption, peel adsorption (grapefruit peel, tea stem).
Open windows for ventilation. Fresh air system. The air purifier is to achieve the diluted formaldehyde concentration through indoor and outdoor air convection.
Photocatalyst aldehyde removal spray (titanium dioxide photocatalyst) decomposes free formaldehyde under the action of ultraviolet rays of sunlight. Amino acid derivative spray, in addition to decomposing and neutralizing free formaldehyde, can also cover the surface of the pollution source to form a protective film, reducing the release of formaldehyde, but after the failure of the protective film, formaldehyde will be released in large quantities. Biological enzyme aldehyde removal agent, in the ideal environment to remove aldehyde effect is very good, but the actual use is not satisfactory.
Fourth, it can be seen that all formaldehyde treatment methods cannot remove formaldehyde in the conjugated state. The only way is to avoid it from the source and reduce the use of foaming agents and glues during decoration. Try not to use synthetic panels, such as granular panels, MDF, laminate flooring, wall panels, etc. Cancel the floor instead of tiles, furniture choose solid wood, such as pine furniture, the price is lower than custom furniture, you can also use hardwood fingerboard, like north American red oak fingerboard.
Fifth, the most advocated method of removing formaldehyde, air convection in addition to formaldehyde, the most commonly used is to open the window ventilation, but in the windless weather, indoor and outdoor air convection is very slow, in addition to the effect of aldehyde is greatly reduced, is a passive way to remove formaldehyde; The air purifier and fresh air system can actively achieve air convection, especially the fresh air system, the air supply outlet exhaust outlet is all over each room, there is no need to open the window, and the formaldehyde concentration is diluted 24 hours a day. #装修那些事 #
