I have been in the decoration industry for many years, and I can tell everyone with certainty that the so-called zero formaldehyde of the business does not exist, but it is just a publicity stunt. Unless they choose to use solid wood for decoration, otherwise, the house after decoration, especially in summer, will exceed the standard of formaldehyde. A universal phenomenon. Removal of formaldehyde in decoration is an unavoidable thing to do. Before the decoration and removal of formaldehyde, we must not only understand the source of formaldehyde, but also know whether the method to distinguish the removal of formaldehyde is true and effective. Here, we will give you a detailed summary of the top ten brands of ceramics.

The main source of formaldehyde

Generally speaking, all kinds of man-made boards, such as plywood, blockboard, particle board, medium density fiberboard, etc., as well as the adhesives used in the decoration process are the main sources of formaldehyde. These are reflected in the furnishings, mainly in the furniture. In fact, most of the man-made board furniture contains formaldehyde. Look at the picture below, the composition of the board:

The main source of formaldehyde for artificial board furniture is the paint layer of the board and the adhesive added in the process of making the artificial board furniture. I don't need to say much about the formaldehyde in the paint layer, but I will mainly mention the adhesive. In the current artificial board technology, there are three main types of adhesives: urea-formaldehyde resin, phenolic resin, and melamine-formaldehyde resin. The name has something to do with formaldehyde. These glues will be released continuously when we use furniture.

From a professional point of view, the amount of glue used is also different for different sheet structures. In fact, the amount of glue used is MDF> particle board> blockboard> plywood> multilayer solid wood board> veneer> solid wood board.

It is not to create panic for you, but it is true that formaldehyde is still volatile for ten or eight years. Therefore, choosing environmentally friendly and healthy furniture is really responsible for the health of the family.

● Select furniture whose formaldehyde emission meets national regulations. At present, my country's health standards for monitoring and defining formaldehyde emission have two levels E1, E2, and E3. Choose furniture that meets E1 environmental protection standards. The E0 level cited by some merchants is actually equivalent to E1 level. It is just for publicity and there is no advantage.

● Regardless of whether composite or solid wood furniture contains formaldehyde. The composite is multi-layer board bonding, there is glue so there is formaldehyde. If there is paint on the surface of solid wood, there is also formaldehyde, and the smell of indoor temperature rise in summer is more obvious. There is no way, you should buy it or you have to buy it, just choose a trusted brand as much as possible.

In addition, paints, textiles, etc. are also seriously polluted by formaldehyde. Everyone knows the formaldehyde in paints. Now the paint market is relatively transparent. If you choose a reliable big brand, you can use it with confidence.

The harm of formaldehyde to the human body

Although formaldehyde is an irritating gas, it has no taste. As the most important and most irritating source of indoor pollution, it is not because it is poisonous, but because it can be released for a long time and slowly, with a release cycle of up to 3-15 years. And 2-3 times more than the standard is usually no smell! If you can smell it, it is a serious overrun! Different concentrations of formaldehyde are harmful to the human body. If it exceeds 6, it may cause pulmonary edema. If it reaches 30, it can cause death immediately!

Here, I really want to persuade everyone, Jane Decoration! More ventilation! Take a lot of time to choose home improvement materials, and say no to formaldehyde from the source as much as possible!
