For mature products that have entered the Chinese market for nearly 10 years, is it better to strengthen the floor? This reporter interviewed relevant experts and manufacturers.
An expert who did not want to be identified believes that strengthening the floor is still the best thickness of 8 mm. Once it exceeds this thickness, there will be problems with its physical properties. His reasons are as follows:
Expert opinions square base density decide floors comfort and service life
Experts believe that in order to achieve better physical performance of laminate flooring substrates, it is necessary to use high density fiberboard with a density between 0.85 and 0.95 grams per cubic centimeter.
The density of high density fiberboard is closely related to the physical properties of the substrate, and the physical properties of the substrate will increase significantly with the increase in the density of the high density fiberboard. Studies have shown that the substrate has the best physical properties in the above density range. From the standpoint of comfort, the base material in the above density range has similar elasticity, feeling of foot and sense of temperature.
Substrate density distribution to meet the floor performance
Experts also believe that controlling the surface density distribution of the substrate is a key factor in satisfying the laying and use of laminate flooring. The control of the uniformity of the transverse density of the substrate can ensure that the density distribution of the substrate in the width direction is uniform, because from the moisture proof point of view, the floor surface and the back plate have different degrees of wet contact due to different usage conditions, and the thickness between different layers has a uniform density. It can make the water absorption expansion ratio produced after moisture absorption more consistent, making the dimensional performance more stable. Because the locking structure is based on the different thickness of the substrate processed between layers, ensuring uniform density between layers is the key to ensure the size, strength and binding force of the buckle, and it is also an important means to make the reinforced wooden floor beautiful and resistant to deformation.
For the expert's point of view, floor expert Huang Dakang dared not agree, he believes that the strengthening of the floor is not necessarily the best 8mm, the best performance.

Experts Fanfangguandian production process determine the quality of the floor
At present, some domestic companies have developed laminate flooring with a thickness of more than 8 mm. The thickness of the substrate used in this type of floor is generally between 9 and 12 mm. The requirement for the substrate is the same as that for 8 mm. The density of the surface needs to reach around 1100 kg/m3, which is necessary for the production of thickened laminate flooring. condition. The high density area of ​​this kind of floor substrate is similar to the 8 mm floor, but the second high density area is thicker than the second high density area of ​​the 8 mm floor, so its elasticity and stability are greatly improved, and the foot feel is also better. . Not only that, because the floor thickness has increased, the floor sound absorption function is stronger, effectively reducing noise. Taking the imitation solid wood floor as an example, it adopts a thicker floor substrate to effectively combine the advantages of the reinforced floor and the solid wood floor, and changes the original method of printing wood grain to the three-dimensional wood grain synchronous press printing. Natural wood style is exhibited. This kind of floor not only visually gives consumers a real wood feel, but also tries to create a solid wood-like comfort quality and a good sound effect on the foot.
Experts also suggested that the production of laminate flooring with a thickness of more than 8 mm has extremely high requirements on the production equipment and technology level of the company. Therefore, only the indexes of the products produced by large-scale and professional enterprises can meet the requirements of the relevant national standards. .
Business Views Floor Thickness Isn't Important Production Process Is Crucial
With regard to the opinions of the two parties on the left, what should the company choose? It is understood that the iconography, Hongnai, Del, Haidi are mostly 8 mm, and Deshi family, Knoksen Sen, Rui Jia is the main push 8 mm above the laminate floor. Asked the reason, Hongwei general manager Li Wei's answer is: “We are not making deliberate choices in the production of 8mm laminate flooring, just because the technology is more mature.†And Wang Jiaping, general manager of Deshishijia, who pushes over 8 millimeters, said : "Increase the thickness. One is to make the laminate flooring feel better. Second, our main line product is imitation solid wood flooring. Its thickness also needs to be more than 8mm." When it comes to laminate flooring, it is thin or thick. When this is a good question, the opinions of the above CEOs unanimously hold that the decisive factor influencing the quality of laminate flooring is not the thickness. When consumers purchase laminate flooring, the key depends on the manufacturer's material and craft level!
