Laminate flooring, substrate layer is the most important
Today, laminate flooring in the market is generally composed of four layers of materials, namely wear-resistant layers, decorative layers, substrate layers, and moisture barriers. The bottom layer is a moisture-proof layer, generally made of polyester material; the base material layer is the main part of the reinforced composite wood flooring, and more uses density board as a base material; the base material layer is a decorative layer and uses a specially processed paper as material. The wear-resistant layer is a layer of anti-wear agent uniformly pressed on the surface of the laminate floor. The methods for general inspection of substrates are as follows: (1) Look at: First, look at the fineness of the substrate fiber, whether it is uniform, with or without impurities; secondly look at its color, use pine wood as the raw material, and retain the pine wood. The true colors, darker colors, longer growth cycle of pine wood, complete development of wood fiber, better physical properties, and white-colored substrates, most of which are fast-growing species. The fast-growing tree species have incomplete development of wood fiber and poor physical properties. (2) Smell: There is no smell in the substrate. (3) Cooking: The floors of different brands can be placed in the same container and soaked in 100°C water for 30 minutes. When they are taken out, the higher the expansion coefficient, the higher the quality. The lower the expansion coefficient, the better the quality. Nature floor del floor decoration

In the four layers, the base layer is the most important. It is the core component of laminate flooring. It uses pine wood and fast-growing species as the main raw material. After peeling and screening, it is mechanically separated and chemically processed using wood or plant fibers. , Incorporation of adhesives and water repellents, and then by paving, molding and high-temperature, high-pressure suppression, its relatively uniform density, mechanical properties close to the wood, is currently more popular in the world of a man-made board.
