The author reminds consumers that if the wood wardrobe of the purchased wooden cabinet exceeds the standard, do not buy it. It is recommended to buy the wardrobe that has reached the e1 standard board. Only the board that meets the e1 standard can be harmless to the human body. Ask the price: Most of the wood wardrobes with excessive formaldehyde use cheap man-made boards, so the price of the whole set of wooden wardrobes is often "ultra-low". Due to the intensive use of inferior glue in cheap man-made boards, the amount of formaldehyde released is seriously exceeded. Smell: Most wooden wardrobes sold on the market, except for all solid wood wardrobes, have wood-based panels. Therefore, you should especially smell when you buy. If you make people cry and sneeze, it means that the formaldehyde emission of the wardrobe is relatively high, there may be problems, do not buy. The easiest way to distinguish can give us more enjoyment of life. The above three coups make your wise choices bring more love to children.
