Look at the package and certificate. Ordinary manufacturers, whether imported or made in China, will use Chinese or Chinese and English logos on the packaging. Beware of packaging in English only, which is likely to be a "smoke bomb" for small manufacturers to deceive consumers. In order to maintain their reputation, regular manufacturers generally use environmentally-friendly raw materials that meet national regulations, but the behavior of small factories is difficult to guarantee. Another point is that merchants are required to show ISO 1400 1 International Environmental System Certification and China Environmental Label Certification.
Step 2 smell it
You can soak the top of the sample in boiling water for one to three minutes to see if it has a stimulating taste. Green floor generally does not smell pungent smell because of low formaldehyde emission. If the pungent smell you smell is strong and even makes your eyes feel uncomfortable, it proves that the base material of the floor contains a lot of free formaldehyde, which will pollute the air.
Step 3 ask an expert
Before buying, ask people in the industry or consult relatives and friends who know how to do it, and ask them to recommend it, focusing on technical instructions and experience. Or go to the building materials market to shop around, don't buy inferior products for cheap, it's too late to regret it.
4. Pro-experience
The more you see, the more you know. If you want to buy a satisfactory floor, you must know your common sense about the floor. In addition to the well-known indicators such as formaldehyde emission and wear resistance, there are also many key indicators such as water absorption expansion rate, static bending strength and dimensional stability that also affect the performance of the floor.
