Warm beds, large closets, compact dining cabinets, soft sofas... Furniture is closely related to our lives, directly affecting the health and quality of life of the whole family, so choose safe and environmentally friendly furniture. Particularly important.
There are various types of furniture on the market, and the pollution release sources of different types of furniture are also different, so the degree of influence on people's health is also different. So what kind of furniture should be chosen? Today, Mutong comes to give you a variety of different kinds of furniture. The long-term source of formaldehyde pollution release, when buying furniture, pay attention to these places.
1. Long-term formaldehyde pollution release source in Chinese paint furniture
The source of formaldehyde pollution in paint furniture comes from two parts:
(1) A wood-based panel without paint;
(2) The amount of paint sprayed inside the furniture is small, the paint film is incomplete, and the release of free formaldehyde in the artificial board cannot be completely closed, which is also a long-term pollution source.
The solid wood paint furniture frame is solid wood. In most cases, the door panel is solid wood, but the side panels, partitions and back panels are mostly fingerboards, blockboards, plywood and other wood-based panels, so there is also a long-term formaldehyde pollution release source.
2. Long-term formaldehyde pollution source of European furniture
High-grade European furniture is made of solid wood carving. Ordinary European furniture is made by MDF, and then painted or painted. Therefore, European furniture is made of MDF, and the surface is painted with paint. The most common is white. Light color such as milky white.
The long-term formaldehyde release source in European furniture comes from the urea-formaldehyde resin glue in the substrate MDF, mainly on the inside of the furniture, especially the back of the bottom plate, the outside of the back plate (by the wall), the drawer box, etc. Where, these areas are not painted or sprayed, so the free formaldehyde in the MDF cannot be blocked.
3. Long-term formaldehyde pollution sources in panel furniture
The most common panel furniture is the â€œcustomized whole wardrobeâ€. The custom-made wardrobe is a typical melamine veneer furniture. The melamine board is made of particle board (some are medium-density fiberboard). The surface is covered with melamine-finished skin and the side is PVC. Furniture for the edge banding. Therefore, the long-term formaldehyde pollution release source of melamine board furniture is the particle board used as the substrate.
There are several cases of formaldehyde pollution sources for panel furniture:
(1) The plain board without the veneer is commonly used on the outside of the drawer bottom, the outside of the furniture back panel, the outside of the bottom panel, etc.
(2) There is no edge seal, which is commonly found in furniture;
(3) The quality of the skin is unqualified, or the edge is unqualified.
In all three cases, free formaldehyde in the substrate is volatilized into the air to form a pollution.
4. Long-term formaldehyde pollution source for decoration and furniture production
The furniture made by decoration is mainly divided into two categories: one is made of finger joint board (toothed board), blockboard (large core board), plywood (multilayer board, solid wood multi-layer board); the other type is Made of veneer or plywood (commonly referred to as "paint-free board" or "ecological board").
(1) Furniture made of blockboard, plywood, finger joints, etc.
The outer surface uses treated decorative panels, or spray paint, does not produce long-term formaldehyde pollution, and some furniture does not do any treatment inside, for the exposed surface of bakelite, plywood and other plain plates, formaldehyde volatilization without any blockage, is the biggest Long-term formaldehyde pollution release source; some furniture interior decoration with PVC decorative paper, but due to poor PVC sealing effect, the free formaldehyde in the artificial board can still be volatilized. Whether the PVC facing material is still a source of formaldehyde pollution needs to be tested.
Note: Fingerboards are often mistaken for solid wood panels that are free of formaldehyde contamination, and are actually wood-based panels with relatively little formaldehyde contamination. The finger joint plate has less glue than the blockboard, and its formaldehyde emission is close to half that of the blockboard.
(2) Furniture made of paint-free board
The furniture made of paint-free board is the same as the PVC veneer furniture, and it needs to be tested to verify whether it is a source of formaldehyde pollution. In addition, the paint-free board has a "single finish" (only one side is decorated with a veneer, the other side is not attached, the plywood or wood board is directly exposed) and the "double veneer". If it is a single finish, it is best to be renovated. Use a strong aldehyde removal agent to treat the side without the finish.
5, long-term formaldehyde pollution source in soft package furniture
Soft furniture includes fabric furniture and leather furniture, the most common of which is the fabric sofa. The outer surface of the soft-packed furniture is leather, artificial leather, or fiber cloth. The middle layer is generally sponge or various fiber mats. The innermost part is solid wood frame and wood-based board lining. The lining board is generally not treated with facing surface. The bare plain board is a long-term source of formaldehyde pollution release; in addition, some sofas with storage functions, the use of wood-based panels is even greater.
After reading the knowledge about the long-term formaldehyde pollution release source of different styles of furniture written by Mutong, I believe that you have a certain direction when purchasing furniture! Mutong hopes that everyone can start from their own health, choose real environmentally friendly furniture, and eradicate formaldehyde pollution from the source!
