What floor has no formaldehyde? What are the classifications of floors?

Few people will avoid using the floor in interior decoration now, but we all know that the floor contains formaldehyde, so is there a floor that does not contain formaldehyde? Moreover, many merchants in the market still insist that the floor of their home is environmentally friendly and does not contain formaldehyde. The following small series will tell you about the classification of floors, which floors have no formaldehyde, and the formaldehyde content of each layer. When buying a floor, you can have a simple understanding and know fairly well.

Floor classification

From the perspective of formaldehyde pollution, floors can be divided into three categories: pure solid wood flooring, solid wood composite flooring and laminate flooring. Among them, solid wood composite flooring includes: three-layer solid wood composite flooring and multi-layer solid wood composite flooring. Different kinds of floors have different levels of formaldehyde pollution.

What floor has no formaldehyde?

1, that is, pure solid wood floor, made of a whole piece of wood, with no other decorative components except surface painting. The formaldehyde emission of this floor is almost negligible and can be regarded as zero formaldehyde floor.

2. Solid wood composite floor is made of three or more layers of solid wood chips, which are cut, glued and pressed into base material, and then high-quality patterned veneer is pressed on the surface, and the surface is decorated by painting process.

The substrate of solid wood composite floor is multi-layer plywood, and the adhesive is mostly urea-formaldehyde resin glue, and the formaldehyde release period is as long as 15 years. The floor surface is decorated with paint to block the release of formaldehyde. There will be no formaldehyde release, but there will be formaldehyde release at the bottom and sides.

The formaldehyde detection value of solid wood composite floor, especially the new house with multi-layer solid wood composite floor, is more than 0. 1 mg in many cases, but so far, we have not found that the indoor formaldehyde detection value of any furniture exceeds 0.3 mg.

3. strengthen the floor. It is a floor made of high-density fiberboard, with decorative layer and wear-resistant layer on the surface and balance layer on the back, which is pressed at high temperature.

The main material is high-density fiberboard, which uses wood fiber and urea-formaldehyde resin glue to release formaldehyde for a long time.

Because the thermal insulation performance of the floor is better than that of ceramic tiles, many families like to use the floor when decorating. However, the problem of formaldehyde content in the floor is indeed more serious than that in ceramic tiles, because it is difficult to avoid using adhesives for board products, so formaldehyde must be contained. This is why some families with children try to avoid using plates when decorating their houses. Bian Xiao also explained in the above what kind of floor formaldehyde content is relatively low, you can choose according to your own situation.
