Laminate wood flooring is the bottom layer of moisture-proof layer, the general use of polyester material; substrate layer is to strengthen the main part of composite wood flooring, the use of MDF as the substrate; substrate layer is above the decorative layer, which is pattern layer, which The first layer is the use of a specially processed paper as the material; wear-resistant layer is to strengthen the surface of the floor uniform suppression of a layer of wear-resistant agent.
In this four layers, the substrate layer is the most important, it is the core component of Laminate wood flooring, it is pine, fast-growing trees as the main raw material, and after peeling and screening treatment, the use of wood or plant fiber by mechanical separation and chemical treatment , Mixed with adhesive and waterproof agent, and then pavement, molding and high temperature, high pressure.
As the wood fiber is added to the adhesive through the high temperature, high pressure, its density is relatively uniform, close to the mechanical properties of wood, is the more popular international a man-made sheet.
General inspection of the substrate approach has the following
First, look at the fineness of the substrate fiber, is uniform, with or without impurities; second look at its color to pine as raw material substrate, retain the pine nature, color darker, pine growth period is longer, wood Fiber development is complete, good physical properties, compared with the white substrate, using mostly fast-growing species, fast-growing species of wood fiber development is not complete, poor physical properties.
Second, look at the substrate has no smell.
Third, you can take different brands of flooring in the same container, soaked with 100 �� water for 30 minutes, look out, the higher the expansion coefficient that the quality of the times, the lower the expansion coefficient, the better the quality. |
