Some formaldehyde testing agencies in the market claimed that the summer is the most volatile season of formaldehyde volatilization, room temperature for each rise of 1 ℃, wooden furniture and flooring, such as volatile formaldehyde, indoor air will increase the concentration of formaldehyde 0.15-0.37 times. Is that really the case? In the case of increased release of formaldehyde, is it more prone to excessive formaldehyde it?
The release of formaldehyde is a slow process. Hot weather or transpiration does accelerate the rate of formaldehyde release. However, the introduction of environmental standards for sheet metal has been considered this factor, so as long as the product meets the corresponding environmental standards, even in the summer, generally do not appear due to increased formaldehyde release caused by excessive indoor formaldehyde situation. Of course, taking into account the decoration of many links are likely to involve formaldehyde problems, so the newly renovated house, it is best to keep the daily ventilation more appropriate.
2. Formaldehyde in the enclosed space, will not produce cumulative stacking effect?
A single sheet does not exceed the standard, but if the whole house a large area of the use of sheet metal, formaldehyde will have a cumulative effect of stacking, and ultimately make the indoor air formaldehyde content exceeded?
The current custom industry formaldehyde standards, the use of a single sheet of formaldehyde emission as a standard. From the principle of formaldehyde release, formaldehyde itself will accumulate in the confined space. In other words, the amount of formaldehyde released from a single sheet is not equal to the formaldehyde content in the air. However, at home and abroad in the development of the corresponding sheet of environmental standards, has been considered the accumulation of formaldehyde superposition effect, and most people do not belong to the confined space, ventilation, air circulation will reduce the air concentration of formaldehyde. Therefore, as long as all the home use of national environmental standards in line with the product, for the space of formaldehyde problems do not have to worry too much. Need to be reminded that the home space will release formaldehyde, in addition to the plate, as well as paint, flooring and fabric, etc., it can not simply use the indoor air detection method to point to a piece of formaldehyde. To prevent the indoor air formaldehyde exceeded, not only to choose high environmental standards of the plate, but also to ensure that other products meet the national environmental standards.
3. Plate furniture, really "short-lived" furniture?
Plate furniture in the country has been not so favored, the reason, in addition to sheet metal furniture more vulnerable to environmental problems, but also with people generally believe that the furniture is not as solid wood furniture, the concept of durable. Is that really the case?
How long will it be for furniture in the end? In fact, with its application environment has a great relationship. Long-term humid environment, it will affect the life of sheet metal furniture. But if the use of the environment is better, the life of sheet metal furniture can actually be very. The reason why people will produce the concept of impracticable plate, mainly early processing technology is not mature plate, coupled with the plate market varies greatly, poor quality of the lack of quality plate manufacturers. However, in recent years the state force to eliminate backward production capacity, sheet metal industry technology upgrades, so that the quality of sheet metal and life on a new level. Therefore, unless it is for the purpose of collection, or do not have to worry about the life of sheet metal furniture.
4. The smell of the plate is not equal to formaldehyde, but the smell of the plate itself is harmful?
The newly installed wardrobe emits a smell. Although the custom businessmen say "smell is the taste of the wood itself", "smell is not equal to formaldehyde exceeded", but the smell itself will be harmful to the body?
Formaldehyde itself is only irritating, there is no smell, so custom furniture exudes a smell, does not mean that formaldehyde exceeded. Want to figure out whether the smell itself is harmful to the human body, first of all to figure out the source of the smell. As the plate itself is a variety of wood processing, natural with a different taste of wood, and some wood flavor is still relatively rich. So when different tastes are mixed together, it may be uncomfortable to smell and even make some people unacceptable. But from a health point of view, whether it is the taste of eucalyptus, or the taste of pine, although bad smell, but they themselves, and even mixed together, in fact, the human body is also harmless.
5. Does the aldehyde plate really contain no formaldehyde?
For the high sensitivity of formaldehyde release, gave birth to a more environmentally friendly level of non-formaldehyde plate. The so-called non-formaldehyde plate, really does not contain formaldehyde?
No aldehyde board, strictly speaking, should be called non-formaldehyde added plate. This non-formaldehyde-added plate does not mean that the plate itself is completely free of formaldehyde, but rather that in the processing of the sheet, no man-made glue containing formaldehyde. Because the artificial wood substrate - natural wood itself is also containing trace formaldehyde (different wood formaldehyde content is also different), formaldehyde is not an absolutely harmful substances, the body itself also contains trace formaldehyde. Ordinary board used in the adhesive is urea-formaldehyde resin glue, this glue itself is a combination of formaldehyde and urea, which will contain formaldehyde, the higher the level of environmental protection plate, the use of glue in the production of formaldehyde content lower. No formaldehyde added plate, the use of formaldehyde is not used M D I glue. Therefore, compared to ordinary wood-based panels, non-formaldehyde plate to a higher level of environmental protection, the formaldehyde emission and solid wood equivalent.
6. In the end is the plate furniture environmental protection, or solid wood furniture more environmentally friendly?
Plate and solid wood, in the end who is more environmentally friendly, it seems to be an answer to the obvious question, but the solid wood customization is really more environmentally friendly than the plate custom? The answer is not necessarily!
Simply from the perspective of formaldehyde release, solid wood environmental protection index is indeed higher than the plate, but the premise is that the use of environmentally friendly wood products, such as water-based paint. Because the paint itself also contains V O C and formaldehyde and other harmful substances. From the protection of the entire earth environment, the concept of environmental protection, the plate is much more environmentally friendly than solid wood. From the perspective of the effective use of timber resources, solid wood on the raw materials specifications, size and other requirements are higher, and the plate not only does not require and can be almost 100% of the use, so that compared with solid wood wood has a higher utilization and lower Of the waste rate, that is more environmentally friendly. Relevant comparative data show that the need to consume a cubic plate of custom products, if replaced by solid wood, usually need to consume four cubic solid wood. In addition, the solid wood has its advantages, high-grade, durable, but compared with the plate furniture, the drawbacks are obvious, it is easy to deformation, cracking, its low-carbon environmental protection and richness is not as plate furniture. Therefore, foreign furniture materials are widely used in the plate, and occupy an absolute large proportion.
7. In addition to aldehyde products, in the end there is no effective?
People for the formaldehyde on the tiger color, gave birth to a variety of known in addition to formaldehyde and anti-formaldehyde products. Do these products fly?
Currently known as formaldehyde in addition to the product, can be divided into two kinds: one is the chemical reaction method, the other is the physical adsorption method. Chemical reaction method, its effectiveness, how long effective and whether there is secondary pollution, there is no relevant experimental data support. Up to now, this method can only eliminate the formaldehyde on the surface of the plate, taking into account the release of formaldehyde is a long process, so its overall role is very limited. The physical adsorption method is theoretically effective, but its adsorption range is limited, and according to the current detection method, it is difficult to determine whether formaldehyde is adsorbed, whether it is decomposed or will be released again. Therefore, for now, the choice of high environmental standards of household products, to strengthen ventilation, equipped with air purifier, is to prevent the best choice for indoor formaldehyde exceeded.
8. Foreign sheet metal environmental standards, must be higher than the domestic?
We always take it for granted that foreign countries pay more attention to environmental protection, product environmental standards must be higher than the domestic environmental standards. Is that really the case?
The environmental standards of the plates are different for each country. China's custom industry for sheet metal environmental standards of high demand, not only has been with international standards, and even beyond the international standards. At present, the plate on the market, according to the different amount of formaldehyde emissions, can be divided into E 0 level, E 1 level, E 2 level, E 0 level for the existing highest environmental rating standards.
