Before purchasing, everyone should understand that the grade of composite flooring is mainly based on the species, pattern, and color difference of the surface floor. The better the material of the surface tree species, the more neat the pattern, the smaller the color difference, the more expensive the price; conversely, the worse the material of the tree species, the greater the color difference, the more the surface scab, the lower the price. The points for purchasing solid wood flooring and selecting solid wood flooring are almost the same, but they should be more concerned about environmental protection.
First of all, the quality of appearance is not only determined by whether the color, texture and paint quality of the surface wood conform to the grading standards. In general, there should be no wood defects such as rot, dead knot, knot hole, wormhole, resin jacket, cracks or patchwork, wood texture and color perception harmony, paint should be uniform, no bubbles, small white spots Such phenomena. The surface should not have obvious stains and damage.
Secondly, select the size of the product. While selecting the appearance, you should also check whether the tongue and tongue around the floor are neat. After assembling any number of floors, observe whether the foundations and troughs are tightly combined. At the same time, whether the floor after the splicing can be touched is even. If there are more prominent hand feelings, the product is unqualified. After touching it, pick up two pieces of multi-layer solid wood flooring and shake it in your hands to see if it is loose.
Finally, the key indicators for selecting intrinsic quality composite wood flooring include formaldehyde content, water absorption, and fire resistance, etc., which can be found by checking the manufacturer's instructions. From the water swelling rate can be seen that its waterproof, moisture-proof performance, the lower the better, preferably less than 2%, followed by less than 5%. Fireworks are burned on the surface. If there are no traces indicating that the fire-retardant coefficient is high, the formaldehyde content is an indicator that cannot be ignored. According to the national regulations, the content of formaldehyde per 100 grams of floor shall not exceed 9 milligrams.
