In our daily life, how do we choose environmentally friendly flooring? This article provides two tips for testing environmentally friendly flooring.
First, the wooden floor saw a new section, carefully smell, look, if there is a pungent smell or glare, it must be a substandard product of formaldehyde, and vice versa can basically be determined to be environmentally friendly products.
2. Soak the top of a small sample in boiling water for 1-3 minutes to see if it has a pungent odor.
Environmentally friendly wood flooring generally does not smell pungent odor due to low formaldehyde emission. If the irritating odor is strong and even the eyes feel uncomfortable, it is proved that the substrate of the floor has more free formaldehyde.
In addition, professionals remind consumers to try to buy in regular shopping malls.
At present, in the issue of the formaldehyde content of the wooden floor and the glue used, the products of the formal enterprise should have the test report of the sampling or inspection issued by the national authority, and the consumer should request and verify it from the merchant.
Therefore, when buying wooden flooring, you must sign a purchase contract with the merchant, and also require the operator to clearly indicate the material information on the contract (invoice) sold, in case of disputes.
