How to avoid buying a toxic floor? First of all, to understand the classification of the wooden floor, all indoor artificial boards are classified in the same level of free formaldehyde emission, that is, regardless of the furniture or the wooden floor, this classification is applicable as long as the artificial board is involved.
The country has not officially released the national standard for the E0 level. At present, most of the E0 standards are customary in the industry. The formaldehyde emission of the E0 floor is ≤0.5mg/L, which is almost a safety level close to the food level, suitable for children and other healthy environments. For those with higher requirements, the E1 level is ≤1.5, which is suitable for general residential interiors. E2 products are larger than this standard and can only be used outdoors.
How to identify the floor with excessive formaldehyde? First of all, it is necessary to look at the packing box of the wooden floor. The manufacturer's wooden floor packing box records the manufacturer, the place of origin, the amount of formaldehyde released, etc. According to the above data, you can know which level of the product belongs to, and keep the outer packing box in the protection of rights. More convenient; Secondly, the wooden floor has obvious pungent and tearing feeling when unpacking, and the formaldehyde emission is definitely exceeding the standard; finally, if there is any doubt about the formaldehyde emission of the wooden floor, the sample can be sent to the authority for testing. In Guangzhou, the Wood Testing Center of South China Agricultural University has a high authority.
Need to be reminded that many organizations detect the overall formaldehyde emission of the indoor environment, it is difficult to prove that it is brought by furniture or flooring, this test has almost no help for rights protection.
