There are many varieties of reinforced laminate flooring, and the products on the market are mixed. It is not easy to buy a suitable laminate flooring. Today, we will introduce 10 aspects that need to pay attention to the purchase of laminate flooring. The owner of the floor provides assistance.
First, the surface wear resistance number: the wear resistance of the laminate floor is determined by the surface wear layer, and is represented by the wear resistance number. The household is generally about 6,000 rpm, and the public is about 10,000 rpm. There are four types of wear-resistant layers for laminate flooring on the market today: the floor area of ​​about 30g of aluminum oxide per square meter has a wear resistance of about 4,000 rpm; the wear resistance of about 38g is about 5000 rpm; The wear resistance of about 44g is about 9000 rpm; the wear resistance of about 62g is about 18000 rpm.
Second, the content of free formaldehyde: laminate flooring contains a certain amount of formaldehyde in the adhesive, excessive formaldehyde is harmful to the human body, if the human body is in a high concentration of formaldehyde for a long time, there will be a risk of cancer. China has issued mandatory standards for the concentration of formaldehyde in public places, and the regulations do not exceed 0.12mg/m3. According to national regulations, the formaldehyde content of laminate flooring is not more than 30mg/100g, preferably less than 9mg/100g.
Third, the water absorption thickness expansion rate: the higher the index, the more easily the floor expands. The state stipulates that this indicator is within 2%.
Fourth, the internal bonding strength: reflect the quality of the bonding between the fibers inside the substrate, the greater the strength, the closer the combination of the various layers of the wooden floor, the state stipulates that this indicator should reach more than 1Map.
Fifth, the surface is resistant to cigarette burning: put the cigarette on the floor to see if there are cracks, dark spots and bubbling on the surface. If not, the floor is flame retardant.
6. Floor Density: The higher the density, the better the mechanical properties of the product and the better the impact resistance. However, under the same conditions, the water swell thickness expansion rate is too large, and the dimensional stability is worse; in addition, the higher the density, the more the product cost increases.
7. Static bending strength and elastic modulus: These two are important indicators reflecting the mechanical strength of the product, mainly determined by the wood and the quality of the glue. Finally, it is reflected in the anti-destructive ability of the floor gutter combination. The higher the index, the floor resistance to external bending. The better the folding strength.
Eight, the surface is resistant to scratches: the surface is resistant to scratches, reflecting the ability of the product to resist sharp hard objects. The higher the surface scratch resistance value, the stronger the ability to resist sharp hard objects.
Nine, surface impact resistance: This indicator consumers can self-test, with a heavy ball on the surface of the product, if there is a more obvious surface depression, the surface impact resistance is poor.
X. Peel resistance: This index reflects the quality of the glue between the surface decorative layer of the laminate flooring and the substrate. For example, the quality of the glue is poor, and the decorative layer will peel off after using the product for a period of time. (The picture in the text comes from the network)
