8 mm and 12 mm Laminate flooring is thin and thick, typically 8 mm and 12 mm. From the perspective of environmental protection, thin is better than thick one. Because of its thinness, it uses less glue per unit area. Thick, not as tall as the density, impact resistance is almost, but the feel is thick and natural. Wear resistance at least 4,000 revolutions The number of revolutions is a representation of the degree of wear on the floor. Previously once demonized the number of revolutions, now in the national standard secondary wear index 4000 rotation and above; a wear-resistant 6000 rotation and above, these are suitable for home products, and 9000 or even more than 10000 rpm Laminate flooring is a commercial-grade standard. Color clarity and wear layer related Laminate flooring is also often referred to as imitation solid wood flooring, so the clarity of its surface color is very important. The wear-resistant layer is often referred to as "wear-resistant paper" and is a relatively transparent material. Above 6,000 rpm, it requires 46 grams of wear-resistant paper to ensure that it meets the requirements. 38 g wear resistant paper can reach 4,000 to 5,000 revolutions. The thicker the wear-resistant paper, the worse the transparency of the floor surface, so choose a reasonable range of wear resistance will also increase the texture of the floor surface texture clarity. Water swelling rate guarantees stability The water-absorption thickness expansion rate reflects the water resistance of the product. The greater the water-absorption thickness expansion rate, the lower the dimensional stability of the same-density product. National standards stipulate that the water-absorption thickness expansion rate should not exceed 10% as qualified, first-class products should be less than or equal to 4,5%, and superior products should be less than or equal to 2,5%. The poor water resistance of the floor in the wet environment, if the floor around the seal is not strict, may occur more obvious expansion, causing size changes, over the size of the General Assembly caused the floor to arch, thus affecting the floor life. Formaldehyde emission of the national standard and European standard China's national standard regulations, no more than 1,5ml/L are in line with national standards, at the time of purchase can request test data. Many companies have also begun to follow the European standards and have been classified into E0, E1, etc. The E0, the average value of formaldehyde emission, is less than 0 and 5 mg/L, and the E1 standard is equal to the national standard. In addition, some companies have also used their own advantages to develop technologies such as "anti-aldehyde" and "hunting aldehyde," and they can also be used as a reference for purchase. Compared with solid wood floors and engineered wood floors made of solid wood, the laminate flooring is almost in terms of comfort. However, because it is man-made, it also has many advantages that wood flooring does not have: Choose nine steps to strengthen the floor: 1, compared with the traditional solid wood flooring, size specifications. 2, more varieties, can simulate a variety of natural or artificial patterns. 3, the overall effect of laying the ground is good. 4, uniform color, visual effects are good. 5. Compared with solid wood flooring, the wear-resistant layer on the most surface of the laminate flooring is specially treated to achieve a very high hardness, that is, the use of sharp hard objects such as keys to scratch, will not leave traces. The biggest advantage of this advantage is that you no longer have to shy away from protecting your floor in your daily life. Moreover, it has higher flame retardant performance, strong resistance to pollution and corrosion, and good pressure and impact resistance. 6, easy to clean and care. When stains fall on the surface of a wooden material, it is easy to penetrate and it is difficult to clean. The surface of the laminate flooring is completely free from this annoyance. Because the surface is a special material, even if the ink drops, it will not penetrate, can only stay on the surface, can be cleaned with a mop. 7. The dimensional stability is good, so it can be ensured that the gap between the floors during use is small and it is not easy to arch. 8, easy to lay, cheaper prices. The main disadvantages of laminate flooring are: 1, compared with solid wood flooring, this type of floor due to the greater density, so the feeling is slightly worse. But this problem should be viewed as: Reinforcing the comfort of the floor is not good enough, but its price is only 1/4 of the solid wood floor, or even lower, and the advantages of the reinforced floor is what the solid wood floor does not have, not all People choose comfort first when choosing the floor. 2. The product has poor repairability and must be replaced once it is damaged. 3, due to the use of formaldehyde adhesives in the production process, so this type of floor there is a certain problem of formaldehyde release, if the formaldehyde emission exceeds a certain standard, will have a certain impact on human health, and cause environmental pollution. The key to selecting an enhanced floor is to see nine elements: 1, see the brand: well-known brands can guarantee product quality and after-sales service. 2, see the material: normal laminate flooring should be based on high density fiberboard as the substrate. 3, see the thickness: the international standard thickness of 8mm, below this thickness is not strong. 4, see the surface wear-resistant rotation: home floor surface initial wear resistance is generally more than 6,000 rpm. 5. To see the amount of formaldehyde released: The standards of green building materials stipulated by international environmental protection organizations are no higher than 9mg/100g. 6, see after-sales service: whether there is no property insurance, there is no warranty card, whether by the factory direct sales, the product is monopoly and so on. 7, see moisture measures: whether there is a special moisture-proof mats, whether there is a thick layer of moisture on the floor, glue is a special floor waterproof glue. 8, to see if the price is fair: compare the quality of the floor and its after-sales service is worth the money. 9, see packaging: If it is imported goods, there should be Chinese identification and customs inspection certificate.
