"Pure natural zero formaldehyde" "environmental pollution-free zero formaldehyde" ... There are more and more so-called "zero formaldehyde" furniture on the market, merchants to "no smell" and "renovation is staying" as a selling point to attract people to buy.
Is there really "zero formaldehyde" furniture? Song Guangsheng, director of the National Indoor Interior Environment and Environmental Product Quality Supervision and Inspection Center, said that "zero formaldehyde" is a marketing method used by some businesses to take consumers' fear of formaldehyde.
Director Song Guangsheng introduced that formaldehyde in furniture is mainly found in urea-formaldehyde-based adhesives because formaldehyde has strong adhesion, which can strengthen the hardness of the board and prevent insects and corrosion. At present, most of the furniture on the market needs to be processed through multiple processes such as veneering, painting and edge sealing. Most of them use adhesives containing urea-formaldehyde resin and phenolic resin, and formaldehyde is here. In addition, the preservatives needed to store the wood also contain formaldehyde.
Even if solid wood furniture uses environmentally friendly adhesives, it does not mean “zero formaldehydeâ€. It is only in the production process that no formaldehyde-containing glue is used or no artificial formaldehyde is added, and there is no guarantee that the finished product has no formaldehyde. In addition, although the environmental protection level of the furniture in the furniture is higher, the formaldehyde content is less, but the excessive amount of furniture placed in the room will also cause the formaldehyde emission to exceed the standard. Therefore, the "zero formaldehyde" furniture is almost non-existent, just a matter of how many!
China's latest revision of "Indoor Decoration Materials and Its Products in Formaldehyde Release Limits" (GB18580-2017) stipulates that the amount of formaldehyde released from wood-based panels and their products is not higher than 0.124 mg/m3. Marked as E1, the new standard will be officially implemented on May 1, 2018. The standard for "E0" furniture that is now popular in the market is that the maximum amount of formaldehyde released is 0.05 mg/m3.
Song Guangsheng suggested that the best way to control indoor formaldehyde pollution is to choose low-cost formaldehyde or solid wood furniture in decoration and furniture. For pregnant women, children, the elderly and allergic people, try to make simple decoration. Installation of new fans can purify formaldehyde pollution; it can also be ventilated by opening windows to maintain ventilation and convection; if activated carbon is used to purify formaldehyde, on the one hand, special deodorized activated carbon should be selected, and in addition, closed small spaces such as wardrobes, bed drawers and drawers must be used. Inside, this will work. At the same time, we must pay attention to timely replacement. In addition, you can also put some green plants in your home. For example, spider plant, green radish, etc. can play a role in degrading formaldehyde.
Director Song Guangsheng reminded everyone that moving into a new home to perceive formaldehyde can not judge whether formaldehyde exists according to the presence or absence of odor. Newly renovated and replaced new furniture rooms must be professionally tested with CMA/CAL testing qualifications. Check in. The formaldehyde testers sold online are products that are not qualified for production. Don't be fooled.
