Experts pointed out that at least one physical and chemical standard such as formaldehyde content, water content, gluing performance and mechanical properties of the floor should be considered. It is not a consumer, that is, it is impossible for industry experts to measure so many indicators. In order to prevent consumers from being deceived at the time of purchase and to protect the interests of consumers, experts have provided the following suggestions for consumers who purchase laminate flooring.
Suggested method of judgment:
First of all, it is recommended that consumers go to brand stores or professional floor stores with brand sales authorizations, and don't want to be cheap.
When purchasing, if you choose to import original products, you should ask the seller for the following information:
â–¡ Incoming goods declaration price, there is a place of origin.
â–¡ Certificate of origin, with the name of the country of manufacture and manufacturer, the type of import, the size, and the quantity.
Some simple test methods can be used when selecting the floor. Commonly used are:
â–¡ See if there is any wear-resistant layer: use ordinary woodworking sandpaper and rub the tens of times on the front of the floor. If it is a fake wood laminate floor, it will be whitened, and the reinforced floor that meets the standard will not change.
â–¡ Not resistant to UV: Usually cheap domestically produced plates are placed on the edge of the window and will fade before the sun shines.
â–¡ See the stitching effect: use three pieces of floor to splicing together, observe the gap size of the floor, whether there are banana boards, height difference, straight angle, interface pattern change, etc. If it is too obvious, it indicates that the quality of the floor is problematic.
â–¡ Look at the color: the floor has a metallic luster and the texture is clear and true. If the surface of the floor is dark, dull, the texture of the pattern is blurred, and the effect is poor, it is undoubtedly a fake product.
â–¡ Look at the touch: The high-density board particles of the good floor are even and non-mosquito, and feel hard to the touch. The density board of the fake floor is of secondary quality, the grain is rough, the color is different, and there are burrs, but because the material of the MDF is different, it is normal for the difference of the color of the floor.
The laminate flooring has formaldehyde, which is a concern of consumers. These experts made a detailed introduction: the substrate of the laminate flooring is high-density board (HDF), and the quality of the product contains trace amount of formaldehyde. When formaldehyde is released, it will become a kind of There are irritating gases. But consumption does not need to worry too much, qualified laminate flooring does not interfere with health, because:
â–¡ Qualified laminate flooring is one or more layers of special impregnated thermosetting amino resin covering high quality high density boards. â–¡ The surface of the substrate, the balance layer on the back side, and the hot-pressed floor (where the balance layer and the wear layer are also impregnated with a thermosetting amino resin before hot pressing). Therefore, the surface sealing performance of the laminate flooring is excellent, and formaldehyde is difficult to release. Therefore, it is necessary to drill holes when experimentally extracting the formaldehyde emission from the laminate flooring.
â–¡ The state has strict control over this. If the amount of formaldehyde released does not reach the E1 standard, it cannot be shipped. However, if the environmental protection capability of laminate flooring does not meet the national standards, then we recommend that consumers do not choose such laminate flooring, because this flooring is relatively low-cost flooring, and its performance is poor in all aspects.
â–¡ Other products, such as solid wood, laminate flooring, parquet, plywood, etc. of certain tree species, also have trace amounts of formaldehyde. And these products have a relatively poor surface seal. The requirements for MDF are not as high as that of laminate flooring, and are more harmful to humans.
