Here are some basic ways to choose a laminate flooring:
(1) Test whether the floor wear-resistant layer with sandpaper rubbed more than ten times in the front of the floor, if it is false strengthening the floor, it will be white, and really hardened floor will not change.
(2) Look at the quality of the material Currently, the base material selected for the laminate flooring is mostly medium- or high-density fiberboard or particle board. Observe whether the pressed base material is firm, not deformed, not swelled, warped, or infiltrated.
(3) Look at the surface of the floor. Carefully touch the surface of the wooden floor with your hands. Is there any sense of roughness? A good laminate flooring should have a smooth surface. The surface wood grain texture should be clear and realistic, the thickness of the plate is equal, the four corners of the floor can not be damaged, cracked, missing corners, should be intact; the surface should not have obvious mechanical scratches; the surface decoration layer is glued with the substrate density fiberboard The quality is better, there can be no peeling, tilting, degumming.
(4) See the thickness of the international standard thickness is 8 mm, less than this thickness is not strong.
(5) Look at the surface wear-resistant rotation This is an important indicator of the quality of composite flooring. Objectively speaking, the higher the wear resistance, the longer the floor should be used, but the value of the wear resistance is not the only standard to measure the floor life. The initial wear resistance value of the home floor surface should be above 6,000 rpm.
(6) To see the amount of formaldehyde released The current domestic standard for the release of formaldehyde is no more than 30 milligrams per 100 grams. The amount of formaldehyde released from green building materials stipulated by international environmental protection organizations is not more than 9 milligrams per 100 grams. Consumers should choose to strengthen the floor Try to pick products that fall below this standard.
Smell the laminate flooring with a nose, even if it has a slightly irritating odor, which means that the formaldehyde content is higher.
(7) See if there is a special moisture-proof floor mat for damp-proof measures, and whether there is a thick damp-proof layer on the floor, and whether the glue is a special floor waterproof glue. With these three measures, it is difficult for the tide to invade.
(8) Look at the packaging If it is imported goods, according to relevant laws and regulations, there should be a Chinese logo and a customs inspection certificate, otherwise the route is suspicious and should not be taken lightly.
(9) Try water-absorption performance The lower the water-absorption coefficient of the laminate flooring is, the better, this indicator can be regarded as qualified within 3%. Otherwise, the floor is wet, or the humidity is relatively high, and the surrounding seal is not In the strict case, deformation will occur and affect normal use. Self-test method, it is advisable to take a small sample and soak in boiling water for 30 minutes to see if the floor is immersed in the water. It can be judged as good or bad: more water, more swelling, and worse flooring.
In addition, we should focus on checking whether the product has an environmental protection mark: high-quality imported boards generally have international environmental protection signs and blue sky patterns. The domestic certification authority for environmental protection standards is the CCEL-China Environmental Labeling Product Certification Committee. The domestic environmental protection label is a ten-ring pattern.
It should be pointed out that the production of some wood floors meets the “national standards†but does not necessarily comply with the “environmental protection standards.†Although both of these are national standards that allow production, the actual “environmental protection standards†are better than “national standardsâ€. Strictly more strict. Only the products with the “Ten Ring†logo issued by the China Environmental Labeling Product Certification Committee are truly green products.
