When the laminate flooring is just facing the market, the thickness is only 6 mm. In the following years, 8 mm flooring has dominated the market. In recent years, the thickness of the floor has been increasing, and now 12 mm floor has become mainstream, and 13 mm and 15 mm thick floors have appeared on the market. This industry trend has caused many consumers to have the illusion: when buying laminate flooring, the thickness is very important, and the thicker the floor, the more weight it means, the stronger, the more durable, and the better the quality. Is this really the case?
Regarding the problem of thick and thin laminate flooring, experts and companies have their own opinions. Some companies believe that laminate flooring has entered the "thick" modern (modern decoration renderings), so the floor is still thick and thick; while some companies think that the laminate flooring The optimum thickness is 8 mm, above which the performance will be greatly reduced. For the laminate flooring that has entered the Chinese market for more than 10 years and is relatively mature, is it thick and thin?
Viewpoint 1: 8 mm for optimum thickness
Substrate density determines the comfort and service life of laminate flooring: For better physical performance of laminate flooring, high density fiberboard with a density between 0.85 and 0.95 grams per cubic centimeter must be used. The density of the high-density fiberboard is closely related to the physical properties of the substrate, and the physical properties of the substrate are significantly increased as the density of the high-density fiberboard increases. Studies have shown that the physical properties of the substrate are optimal over the above range of densities. From the viewpoint of comfort, the substrate in the above density range has similar elasticity, foot feel and temperature feeling.
Uniform density distribution of the substrate satisfies the performance of the reinforced floor: controlling the surface density distribution of the substrate is a key factor in meeting the laying and use of the reinforced wood floor. Controlling the uniformity of the lateral density of the substrate ensures uniform distribution of density in the width direction of the substrate, because from the viewpoint of moisture resistance, the surface of the floor and the back sheet are different due to different use conditions, and the degree of moisture contact is different, and the thickness of the layers is uniform. It can make the water swell expansion rate after dampness more consistent, and make the dimensional performance more stable. Since the lock structure is processed based on different thickness substrates between layers, ensuring uniform density between layers is the key to ensure the size, strength and bonding force of the lock, and is also an important means for making the laminate flooring both beautiful and resistant to deformation.
Viewpoint 2: The production process determines the quality of the floor, 8 mm is not optimal
At present, some domestic enterprises have developed laminate flooring with a thickness of more than 8 mm. The thickness of the substrate used in this kind of floor is generally between 9 and 12 mm. The requirement for the substrate is the same as that of 8 mm. The density of the surface needs to be about 1100 kg/m3, which is necessary for the production of thickened laminate flooring. condition. The high-density area of ​​this type of floor substrate is similar to the 8 mm floor, but the second high-density area is thicker than the sub-high-density area of ​​the 8 mm floor, so its elasticity and stability are greatly improved, and the foot feel is better. .
Not only that, because the thickness of the floor is increased, the sound absorption of the floor is stronger and the noise is effectively reduced. Taking the imitation solid wood floor as an example, it uses a thick floor substrate to effectively combine the advantages of the laminate floor and the solid wood floor, and the original method of printing the wood grain is changed into a three-dimensional wood grain synchronous pressing printing, truly It shows the natural wood style. This kind of floor not only gives the consumers a real sense of solid wood, but also strives to create a solid wood-like comfort quality and good mute effect on the foot.
The production of laminate flooring with a thickness of more than 8 mm has extremely high requirements for the production equipment and technical level of the enterprise. Therefore, only the indicators of products produced by large and professional enterprises can meet the requirements of relevant national standards. Therefore, when we purchase the laminate flooring, we need to recognize that the determining factor of quality is not the thickness. The key depends on the manufacturer's materials, strength and process level.
“In fact, the thick plate is the same as the thin plate. Once the surface is worn out, it cannot be used. Therefore, the quality of the floor surface layer is largely related to the service life of the wood floor, not the thickness of the board.†Mr. Huang, the industry insider, said that the impact The decisive factor in strengthening the quality of the floor is not the thickness. When consumers purchase the laminate flooring, it depends on the manufacturer's materials and process level.
Industry insiders reminded that at the same price, it is better to buy 8mm flooring for branded wood flooring, and not to buy 12mm flooring for miscellaneous brands. “It looks thick, but because of the huge difference in cost, process and production technology, the brand is thick. The service life may not be as long as the thin plate of the big brand."
