Environmentally friendly wooden floors, as the name implies, are floors with less pollution, but the national assessment standards for environmentally friendly wooden floors are:
National standard regulations: Floor formaldehyde emission of less than or equal to 1.5mg / L is to comply with the new national standard regulations and meet indoor environmental health requirements.
A simple way to judge environmentally friendly wooden floors:
Saw a new section of the wooden floor and carefully smell and see. If it has a pungent taste or a dazzling feeling, it must be a substandard product with formaldehyde exceeding the standard, otherwise it can basically be determined to be an environmentally friendly product.
In addition, consumers can soak the tip of a small sample in boiling water for 1-3 minutes to see if there is a pungent odor. Environmentally friendly wooden floors generally do not smell pungent odor due to the low formaldehyde emission. If the irritating smell is very strong and even makes the eyes feel uncomfortable, then it proves that the floor substrate has more free formaldehyde.
In addition to the fact that the floor itself contains formaldehyde, which will cause pollution to the indoor environment, the choice of the floor cannot ignore the installation problem. If the installation is not standardized, it will also affect the environmental protection. In addition, if the adhesive in the floor does not meet the standard, it will also cause indoor formaldehyde pollution. Therefore, while choosing wooden floors with good environmental performance, consumers should also pay attention to environmental protection and cleanliness in related processes.
Other methods for judging environmentally friendly wooden floors:
1. Judging the packaging of environmentally friendly wooden floors and looking at the packaging
Look at the packaging, look at the certificate. Generally, regular manufacturers, whether it is purely imported or domestically produced, will use Chinese or Chinese-English text marks in packaging.
Regular manufacturers generally use environmentally friendly raw materials in compliance with national regulations in order to maintain their reputation, and the behavior of small factories is difficult to guarantee.
2. Judging experts on environmentally friendly wood floors
Ask people in the industry or consult relatives and friends who know the industry before buying, and let them recommend it. Focus on asking for clear technical instructions and experience.
Or go to the building materials market to run a business, shop around, and buy low-quality products for a cheap price. You will regret it too late.
3. Judge the experience of environmental protection wooden floor
See as much as you can. If you want to buy a satisfactory floor, you must understand the common sense of the floor.
In addition to well-known indicators such as formaldehyde emission and abrasion resistance, there are many key indicators such as water swelling rate, static bending strength, and dimensional stability, which also affect the floor performance.
