According to Shandong TV Station's TV life channel "Life Help", many citizens pay attention to environmental protection when they decorate their houses. Those that have green certification are not necessarily green. What kind of floor should be chosen when decorating? ? Which floor is green?

The floor should be environmentally friendly, pure solid wood flooring is best

Life help reporters learned from the floor store in the building materials market in Jinan, the provincial capital. At present, the floor commonly used for home decoration has pure solid wood flooring, solid wood composite flooring and laminate flooring. Each floor varies in price from five to sixty yuan to several thousand yuan depending on the quality.

“The first layer of the reinforced board is a wear-resistant layer of aluminum oxide, which is pressed by a high-density board.”

"The solid wood composite is pressed one by one, and the pure solid wood is the whole piece of wood."

According to the reporter, the solid wood floor is made of a whole piece of wood. The advantage is that it is green and environmentally friendly. The disadvantage is that it is easy to deform, crack and difficult to care. The reinforced floor is made of high-density board as the base material, and is pressed with the wear-resistant layer and the decorative paper layer. The advantage is fireproof and wear-resistant. The solid wood composite floor is made of high-quality hardwood as the surface, and is pressed with multi-layer high-strength plywood. The solid wood composite floor and the laminate floor are artificial boards, and the pollution is relatively large.

Claims that most of the environmental compliance tests are exceeded

The sales staff told the helper that the pure solid wood flooring is processed from natural wood and does not contain formaldehyde, while the solid wood composite flooring and laminate flooring use glue in the processing process, so it will contain formaldehyde, three types of flooring, and the formaldehyde content of the laminate flooring is relatively speaking. maximum. However, for the floor that is sold by the company, the bosses are self-selling, promising that the amount of formaldehyde released is in line with national standards, and even meets the top international standards of E0.

"Formaldehyde we all meet the national standards, this is the board to do the floor heating"

"The national standard is E1 grade, the formaldehyde content is less than a little, we are E0 grade, less than a few tenths."

The floor with an average formaldehyde emission of less than 0.5mg/L belongs to the E0 standard. This is an international standard. At present, the standard implemented in China is the E1 standard, that is, the average amount of formaldehyde emission is less than 1.5mg/L. Although every floor seller praises the environmental protection of their own flooring, this is not the case. The shop has randomly purchased six different brands of flooring in Jinan and Qingdao building materials market. It found that only two brands of floor formaldehyde emission reached the E1 standard. The remaining four unqualified floors have a formaldehyde emission of 19 mg per liter.

"Tomorrow we will send the sampled floor to the Shandong Quality Inspection Center for re-examination. When the results come out, we will expose the brands of these unqualified floors according to the situation."
