Recently, the wood flooring industry has been arguing about the thickness of the laminate flooring. Some companies believe that the laminate flooring has entered “thick†modernism, so the floor is still thick. Some companies and experts believe that the optimal thickness of the laminate floor is 8 mm, and the performance above this thickness will be greatly reduced. For the more mature products that have entered the Chinese market for nearly 10 years, is the laminate floor thicker or thinner?
An expert who asked not to be named believes that the laminate flooring is still 8 mm in thickness, and once it exceeds this thickness, its physical properties will be problematic. His reasons are as follows:
Substrate density determines floor comfort and service life
Experts believe that to achieve 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.
Substrate density distribution evenly meets floor performance
Experts also believe that controlling the surface density distribution level of the substrate is a key factor in meeting the laying and use of laminate flooring. 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.
For this expert's point of view, the floor expert Huang Dakang did not agree. He believes that the laminate flooring is not necessarily the best of 8 mm, and the best performance.
Production process determines floor quality
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.
Experts also pointed out that 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. .
Thin floor thickness is not important, the most important production process
For the two opposing experts, what choice should the company make? It is understood that the iconostasis, Hong Nai, Del, Haidi are mostly 8 mm, while Deshi Shijia, Knoxenhua and Ruijia are mainly pushing the laminate floor of 8 mm or more. Asked the reason, the general manager Li Wei's answer is: "We are not deliberately choosing 8mm laminate flooring, just because the technology is more mature." Wang Jiaping, general manager of Deshi Shijia, who is mainly pushing 8mm or more, said : "Increase the thickness, one is to make the floor feel better, and the second is that our main line products are imitation wood floors, and the thickness is also required to be more than 8 mm." When it comes to strengthening the floor is thin or thick When this question is good, the opinions of the above-mentioned CEOs agree that the decisive factor affecting the quality of the laminate flooring is not the thickness. When consumers purchase the laminate flooring, the key depends on the manufacturer's materials and technology level!
